Call for Abstracts

This symposium explores advances in fundamental and applied electrochemistry and electrochemical systems to enable efficient, economical, and sustainable chemical manufacturing. With renewable electricity increasing its penetration into the grid, opportunities to use electrochemistry in chemical manufacturing economically and sustainably are ever growing. By utilizing electrochemical methods, processes can be decarbonized when using renewable electricity, wastes and hazardous intermediates can be reduced or eliminated, alternative feedstocks can be used, and modular chemical production units can be implemented.

This symposium covers topics including:
(1) Electrolysis of organics such as those used for manufacturing commodity chemicals, fine chemicals, and pharmaceuticals
(2) Water electrolysis for hydrogen and oxygen utilization in chemical manufacturing
(3) Inorganic electrolyses including, but not limited to, chloro-alkali and aluminum electrowinning
(4) Electrochemical separations for chemical manufacturing
(5) Electrolysis for recycling/upcycling
(6) Materials degradation issues impacting chemical manufacturing processes and equipment

Traditional petrochemical and mineral feedstocks are considered in addition to emerging feedstocks such as biomass, CO2, nitrate, and waste streams. Contributions may address areas including electrocatalyst, electrolyte, and membrane development; electrochemical reaction engineering; reactor design; separation unit design; integration of electrochemical units into chemical production processes; process intensification; corrosion/degradation; and techno-economic/life-cycle analyses. Experimental, computational, modeling, and simulation approaches, as well as process development efforts, are solicited. Invited and submitted presentations from industry, national labs, and academia are included.

This conference relates to all aspects of additive manufacturing (2D, 3D and 4D printing) of electrochemical or solid state materials and systems which utilizes 1D, 2D, 3D materials with a focus towards soft robotics and wearable sensors and devices. 4D printing refers to single-material or multi-material printing of a device or object that can be transformed from a 1D strand into pre-programed 3D shape, from a 2D surface into preprogramed 3D shape, and is capable of morphing between different dimensions. Such transformations are facilitated by, e.g., heating, light, or swelling in a liquid, electrochemically and by programming different sensitivity to, e.g., swelling into various parts of the designed geometry. These techniques offer adaptability and dynamic response for structures and systems of all sizes, and promise new possibilities for embedding programmability and simple decision making into non-electronic based materials. Potential applications include: robotics-like behavior without the reliance on complex electro-mechanical-chemical devices as well as adaptive products, garments or mechanisms that respond to user-demands and fluctuating environments. Mechanical metamaterials are structured materials with mechanical properties defined by their structure rather than their composition. By carefully designing their structure, materials with properties not found in nature, such as negative compressibility (contract when pulled) can be made. Novel developments include the use of elastic instabilities, origami-based materials and programmability, where a single materials function can be changed by pushing. The construction of such materials often relies on forms of (multimaterial) 3D and 4D printing. New innovative technologies and materials processing for energy storage, soft batteries, energy harvesting, display, sensing for soft robotics, are also an integral part of this conference.

The symposium is focused on “out-of-the-box” approaches and developments in materials, components and systems for addressing the grand challenges in the area of electrochemical energy systems. Of particular interest are innovations in materials, methods, designs, and analytical strategies for realizing sustainable and efficient energy conversion, storage and transmission, not limited to fuel cells, batteries, capacitors, PEC and photovoltaics. Contributions to new methods to characterize, model and analyze interfaces, cell and system performances in aqueous and non-aqueous environments are of particular interest to the symposium. The symposium will feature oral presentation, poster, and invited talks from subject-matter experts.

As a part of this symposium under “Ideas, Interchange & Initiative” (Triple I) abstracts can be submitted based on premature and unexplainable results. The aim of this session is to accomplish a complete exchange of scientific ideas and related difficulties in understanding and interpreting the findings. Speakers are expected to present their results in <10 minutes and reserve the remaining time for discussions between the speaker and the audience to explore solutions and collaboration. Please label your talk as A1- Triple I.

Lithium-ion batteries have driven the portable electronics market's tremendous growth and their use in transportation and grid storage sectors are expanding at a fast rate. Further boosting the energy density of these batteries requires higher voltages and greater electrode materials capacity. This symposium is intended to provide a forum for dissemination of new advances and developments in Li-ion batteries which includes new or improved materials and understanding, electrolytes, interfaces/interphases, separators and electrochemical testing.

Electrical energy storage is critical for supporting the integration of renewable energy sources (e.g., wind and solar) and increasing the capacity and reliability of the future electricity grid. Electrochemical energy storage systems have the potential to fulfill this need. This symposium seeks oral and poster presentations on advances in materials, technology and designs, results of performance demonstrations, and economics analysis. The technologies of interest include redox-flow battery systems, metal-air rechargeable batteries, electrolyzers, capacitors, and other rechargeable electrochemical energy storage systems that have the potential to meet the cost and efficiency requirements of large-scale deployment.

This special symposium is dedicated to students working on energy storage and energy conversion. In the student slam, we offer an opportunity for students to present flash oral presentations of their work in a 10-minute time slot. All students enrolled at any valid degree-granting institution may submit an abstract describing the presentation. Of particular interest are new materials and designs, performance studies, and modeling of all types of batteries, supercapacitors and fuel cells, including aqueous, non-aqueous, polymer electrolytes, solid electrolytes, and flow systems.

From portable electronics to electric vehicles and renewable energy storage, batteries continue to penetrate deeply to our daily life and industrial uses. With the rapid increase of battery usage, a huge amount of spent batteries will be generated in the coming years. At the same time, the booming battery manufacturing will also result in the resource shortage and price increase of critical metals such as lithium, cobalt, nickel and copper. In addition, the flammable and toxic waste generated from disposal of used batteries can cause severe environment pollution if not carefully treated. Therefore, it is highly desirable to develop efficient technologies to recycle and reuse batteries for the benefit of both recapturing valuable materials and mitigating environmental pollution. In the past a few years, significant effort has been made in the development of better designs and processes to enable sustainable battery recycling. This symposium will provide a forum for scientists and engineers to communicate their recent progress and exchange ideas in the area of battery recycling and reuse. Topics addressed in this symposium will include (but not be limited to): (1) Recycling and reuse of lithium-ion batteries, including cathode, anode, electrolyte and other materials; (2) Recycling and reuse of lead-acid, nickel metal hydride and other rechargeable batteries; (3) Recycling and reuse of primary batteries, such as Li-MnO2, Zn/Ag-MnO2, and Zn-carbon batteries; (4) Process intensification and cell/battery design for improved recycling and reuse.

Advanced semiconductor products that are true representatives of nanoelectronics have reached below 12 nm. Depending on the application, the nanosystem may consist of one or more of the following types of functional components: electronic, optical, magnetic, mechanical, biological, chemical, energy sources, and various types of sensing devices. As long as one or more of these functional devices is in 1-100 nm dimensions, the resultant system can be defined as nanosystem.

In addition to traditional areas of semiconductor processing, novel topological insulators are of interest, which may lead to new applications of nanosystems. We will have a special session on data driven dielectrics. Recently data-driven materials science is of great concern because it opens a door to discover new innovative materials. This method can be applied to dielectric materials. Here at first, a database is prepared by automatic calculation, and the virtual screening is done using the database by machine learning. Then, high throughput real screening is done for the candidates to find a new dielectric. In this session, we demonstrate the work flow for new dielectric and showcase the discovery.

Papers may contain both theoretical and experimental work, and papers dealing with either area are considered.

The path from discovery, invention, and scientific understanding to well-engineered products and processes is complex, and involves integration of a wide range of skills and perspectives. This is particularly true in electrochemical engineering, where the development of viable processes in energy, environment, health care, or information technology requires understanding molecular mechanisms, tailoring new materials, and integrating data over a wide range of scales in order to scale-up, design, and develop manufacturing methods to produce reliable devices and products at low cost. A clear understanding and creative application of the fundamentals are essential to successfully address these challenges.
The goal of this symposium is to draw together the collective interests of scientists and engineers skilled in moving along the path from ideas to profits. The reduction to routine use of the approaches presented here will define essential engineering methods for emerging electrochemical applications for which increased predictability is of high importance.

This invited-only symposium features tutorial talks to provide the general audience with an overview of technical and commercial challenges for wide-scale deployment of water electrolysis. As low-cost electricity has become more common due to the dramatic cost decreases of wind and solar energy, water electrolysis offers a promising pathway to convert low-cost electricity into chemical energy. The hydrogen and oxygen generated have the advantage of taking electrical energy and shifting it over time and applying it to a range of other energy or product sectors like industry and transportation. Electrolysis has the ability to be performed through a variety of different approaches with various challenges and opportunities. This tutorial focuses on topics that include:

(1) Polymer electrolyte (acidic) electrolysis
(2) Traditional – liquid alkaline electrolysis
(3) Alkaline membrane electrolysis
(4) High temperature electrolysis, and
(5) Other novel and/or hybrid approaches to electrolysis

The tutorial focuses on aspects that include the materials and systems approaches needed to achieve advances in performance, cost, and durability.

Water electrolysis represents a clean and sustainable approach to producing hydrogen. However, the cost of hydrogen production from this process is still prohibitive due to significant electricity consumption and materials cost. High-efficient electrocatalysts for either oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) may enable lowering the over-potential of electrochemical reactions so as to improve the overall energy efficiency of water electrolysis. The development of advanced catalysts may also help to reduce the loading of precious metal catalysts or to replace them with non-precious metal catalysts. This symposium seeks novel or advanced water electrolysis catalysts that include but are not limited to the following categories:

(1) Catalyst supports with extremely high corrosion resistance (>1.5V vs. SHE)

Significant coupling often exists between the electrical, chemical, and mechanical responses of the materials used for batteries, fuel cells, chemical separators, and other high performance energy conversion/storage devices. In these systems, electrochemical reactions affect stress evolution, deformation, and fracture. Similarly, stress evolution, deformation, and fracture can also affect electrochemical properties, device performance, and durability. This symposium provides a forum for the presentation of original research concerned with the interplay between mechanics and electrochemistry.

Topics of interest include, but are not limited to, experimental and/or modeling studies of:

Heterogeneous functional materials (HeteroFoaMs) are pervasive in electrochemical devices. These devices consist of multiple materials combined at multiple scales (from atomic to macro) that actively interact during their functional history in a manner that controls their collective performance as a system at the global level. Examples include composite mixed conductors, nano- or microstructured heterogeneous materials, mechanical alloys, nanostructured interfaces and heterostructures, and many other combinations that typically serve as the heart of devices such as fuel cells, electrolyzers, batteries, solar cells, capacitors, thermoelectrics, and separation membranes. The functional behavior of these materials occurs at multiple scales of length and time. The electrochemical science that makes such technologies work rests on our knowledge and understanding of the science that controls that functionality of such materials, and the design of new HeteroFoaMs to enable new devices, or improve the performance of existing devices.
The principal motivation for this symposium is to provide a forum to discuss the science that controls emergent properties in heterogeneous functional materials as a foundation for design of functional material devices with performance not bounded by constituent properties. The symposium includes invited speakers to present a general definition of the problem, the state-of-the-art on a few specific technology areas such as electrochemical conversion of energy to electricity, membranes for selective transport, and charge storage devices. Papers are solicited in the following topics of interest, but are not limited to:

(1) Novel modeling approaches to elucidate fundamental phenomena in 3D microstructures
(2) Advanced 3D imaging and characterization techniques
(3) New constitutive theory to correlate material properties to performance
(4) Advanced material synthesis and manufacturing methods to create highly ordered microstructures
(5) New concepts for the design of novel materials for electrochemical applications
(6) Applications of heterogeneous functional materials in devices for energy conversion and storage

The utilization of renewable energy has substantially driven more attention into electrolysis technologies. As renewable energy emerges and penetrates further into the energy market, the storage of surplus “off peak” electricity has received widespread attention. An electrolyzer can utilize “off peak” electricity from solar or wind farms to produce hydrogen or other fuels (e.g., ammonia, methanol, ethylene). These chemicals can subsequently be operated in a fuel cell mode to generate electricity or used as intermediates for other industrial applications. Compared to conventional batteries, the chemical storage of renewable energy has advantages of high energy density, long duration, and more flexibility.
Therefore, this symposium aims to call papers for recent advances in electrolysis as a means for renewable energy storage. The covered technologies can include water electrolysis, CO2 conversion NH3 synthesis, or other electrolysis technologies. Interested areas are described below:

(1) Components development (catalyst, membrane, porous transport layer, bipolar plates)
(2) Component degradation mechanism and accelerated stress testing protocol
(3) Multiple-scale physics modelling

Recovery, conversion, and reuse of energy-dense/expensive molecules like N and P compounds have attracted increasing attention in the electrochemistry community as we increasingly need green energy carriers, and to address global nutrients and water/energy sustainability issues. Significant R&D effort is ongoing in the field to develop efficient and safe processes for fuel and nutrient recovery. There is also a need for ongoing conversations in the scientific community around experimental techniques, controls, and methodology to ensure robust and accurate results in this emerging area. As such, a statement regarding controls is required in the abstract (e.g., argon controls, isotope labeling, and assessing NOX contaminants for electrochemical reduction of nitrogen to ammonia). In this symposium, the following topics are of interest:

(1) Using electrical energy to convert nitrogen-containing compounds into useful products
(2) Using nitrogen-containing compounds as fuel which may also produce other useful byproducts
(3) Electrochemically-driven nutrient recycling or recovery
(4) Experimental techniques, controls and methodology to ensure rigorous evaluation of performance

The goal of this symposium is to bring together scientists interested and working in diverse areas of computational electrochemistry, in order to stimulate their awareness of common problems and group interests; facilitate exchange of ideas and opinions; and enable global, unifying views on this emerging interdisciplinary branch of electrochemistry and computational science. The symposium is devoted to ALL ASPECTS of computer and computational method uses in electrochemistry, including (but not necessarily limited to): quantum chemical and molecular simulations in electrochemistry (ab initio, Monte Carlo, molecular dynamics, etc.); digital simulations of electrochemical transport and kinetic/electroanalytical problems (continuum modeling, including PDE/ODE/DAE solving); multi-physics and multi-scale simulations in electrochemistry; computer-aided data analysis in electrochemical kinetics and electroanalysis; engineering simulations and other computations relevant to electrochemical engineering; software, problem-solving environments, expert systems, databases, web-based programs, grid applications, etc., for electrochemistry.

Redox flow batteries have been recognized as an important perspective technology for stationary energy storage, including grid-scale energy storage thanks to their high power performance, flexible design, and ease of scaling-up. The present state of the art is mostly represented by the all-vanadium redox flow batteries, even though many inorganic and organic electroactive systems have recently been proposed as alternatives. In all-liquid systems, the active species are dissolved in solvents; but the hybrid systems, in which the active species exist in distinct phases (e.g., liquid, solid or gas), can operate in three subcategories: solid/liquid, semi-solid, and liquid/gas. Mechanisms of operation and approaches to the optimization of their performance obviously differ. There is a need to develop or identify robust organic, inorganic or hybrid compounds that could function as reversible redox species in a rechargeable battery under flow conditions. Special attention shall be paid to synthesis, modification, characterization, and deep understanding of the operation of novel redox active compounds of potential utility to redox flow rechargeable batteries.

The symposium includes invited presentations, reviews, and tutorial papers and contributed papers. Papers are solicited on the fundamental and applied aspects of redox flow batteries for energy storage. Of particular interest are new materials and designs; new anolytes and catholytes; performance studies; and modeling of all types of redox flow batteries, including aqueous and non-aqueous systems. This symposium aims at bringing together researchers working in different areas of fundamental physical and analytical electrochemistry as well as electrochemical science and technology. Both experimental and theoretical papers are welcomed in an effort to forge a stronger link between the experiential parameters and resulting properties of systems of interest to the area. Additional specific areas to be covered include the design of cathode and anode materials; new preparative and processing approaches; fabrication of advanced materials and electrode characterization including in-situ and ex-situ methods; electrochemical properties and performances; electrode-electrolyte interfacial chemistry; computational modeling; and redox processes, together with ionic transport and reaction mechanisms.

The symposium provides an interdisciplinary forum for exchange of ideas and discussion of new results in research dealing with the fundamental and applied aspects of such electrocatalytoc processes as oxygen reduction reactions, hydrogen evolution (generation) and oxidation, as well as conversion (reduction) of carbon dioxide. Papers are solicited in all areas of electroanalytical, kinetic and mechanistic studies (also at molecular level); development of novel catalytic materials (utilizing noble metals, alloys, surface-decorated, and nanostructured systems, ceramic materials, nanostructured metal oxides, and distinct carbon supports (including graphene in simple and functionalized forms); molecular or metaloorganic materials including N4-transition metal microcycles, metal-Nx type catalysts, enzymes or their combinations, microbial biofilm-based layers and various hybrid systems; modeling, simulation, and evaluation of electrode systems for the electrocatalytic processes mentioned above, as well as discussion of related interfacial phenomena. The symposium includes both invited and contributed papers on all aspects of the related electrochemical studies, physics, and materials chemistry and engineering of catalytic systems. The goal is to bring together scientists and engineers of different backgrounds that are active in the areas mentioned above. During the symposium, we hope to outline important directions for the future.

The symposium covers all the aspects of electrochemistry at nanoscale: from nano-structured and nanoporous materials; structure of double layer and electrokinetic phenomena at nano-interfaces; electrochemical processes in nano-confined spaces and functional materials at nanoscale, including nano-catalysts, nano-cluster catalysis and nano-zymes and bio-inspired materials for electrocatalysis. The symposium invites papers on new developments on synthesis and electrochemical evaluation of nanomaterials as well as experimental approaches of studying the phenomena occurring at electrified interfaces at nanoscale or in nano-confined electrolytes. The symposium also invites papers in which nanostructured materials and interfaces are being integrated in electrochemical devices, which benefit of or display the specific properties that arise from the nanoscale features.
Keynote lectures are presented by invited speakers.
