With the efforts to mimic biological neural systems and demonstrate brain-like energy efficiency in silicon-based computing systems novel materials processing, devices and circuits are evolving. This symposium addresses the devices for the hardware requirements using nanoscale solid state and electrochemical materials that enable neuromorphic computing and next-generation AI technologies. This includes in-memory computing and implementation of deep neural network circuits. In some instances, materials and device codesign, and device and circuit codesign, are required through extensive simulation and processing for system implementation. Issues like energy efficiency and performance enhancement are required to emulate the brain's connectivity in hardware. The switching devices that replicate the electronic synapse need to reduce the device-to-device or in-device stochasticity. It is also required to understand how these materials/devices (mechanisms) work for neuromorphic applications.

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.

This special symposium is dedicated to students working on energy storage and energy conversion. The student slam offers students the opportunity 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 their presentation. Of particular interest are new materials and designs, performance studies, and modeling of all types of batteries, supercapacitors, and fuel cells, including aqueous, nonaqueous, polymer electrolytes, solid electrolytes, and flow systems.

Lithium ion batteries have driven the portable electronics market's tremendous growth and their use in transportation and grid storage sectors is expanding at a fast rate. Further boosting the energy density of these batteries requires higher voltages and greater electrode materials capacity. This symposium intends to provide a forum for the dissemination of new advances and developments in Li-ion batteries which include new or improved materials and understanding, electrolytes, interfaces/interphases, separators, and electrochemical testing. Novel battery systems beyond lithium ion, such as lithium sulfur-, sodium, and magnesium-based systems, are also included.

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 economic 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.

Developing characterization and diagnostic techniques, methods, and tools to better understand the degradation pathways and failure mechanisms of a battery is critical for meeting current demands for performance, cycle life, and safety of electrochemical systems on all scales. Awareness of battery degradation and failure mechanisms allows for both a targeted approach to addressing safety concerns during a technology’s development and a metric for determining a battery’s current state during operation. Characterization techniques enable the fundamental understanding of degradation/failure pathways and the associated extrinsic parameters which influence it. Battery diagnostics are used to determine a battery’s state of health and state of stability (likelihood for failure) during operation by pinpointing degradation/failure pathways, (some of which might have been discovered through characterization) and used as feedback to a battery system. Advanced diagnostic tools can allow for informed and timely system level decisions on a battery’s continued operation after a potential cell failure is identified. This symposium highlights innovative techniques and new discoveries in battery characterization and the ways in which degradation and failure are diagnosed while a cell is operational.

Metallic anodes, such as Li, Na, Mg, Ca, Zn, and others, are at the forefront of next-generation anodes for high-energy-density rechargeable batteries. However, the poor reversibility of plating and stripping of these metal anodes greatly hinders the long-term cycling of rechargeable batteries. A comprehensive understanding of deposition/stripping mechanisms and the corresponding interfacial processes will greatly benefit the future design of electrode and electrolytes. This symposium focuses mainly on the following aspects:

1) Mechanisms of metal plating and stripping during the cycling;

2) Impact of anode/electrolyte interface (i.e., structure and composition) on cyclability;

3) Electrolyte and interfacial innovation for next generation metal batteries.

The symposium focuses on new materials and new processes for the application of binder materials in the electrochemical system. Lately, electrode binders have attracted significant attention due to the expanded research effort in electrochemical energy storage and conversion for realizing sustainable and efficient energy conversion, storage, and transmission. We encourage submitting binder materials applied in fuel cells, capacitors, PEC, and photovoltaics. Physical properties contributing to multifunctionality of binders applied to electrode materials such as silicon, sulfur, etc., for batteries and solid state electrolyte are of particular interest. The symposium covers new materials development, electrode and electrolyte processing and interface characterization, as well as system performance. The symposium features oral presentations, posters, and invited talks from subject matter experts.

The symposium brings together researchers investigating interactions between temperature and battery behavior at a range of length scales, time scales, and severity. Batteries generate heat during charge and discharge, requiring the need for thermal management or heat rejection. However, the complex and stochastic electrochemical phenomenon of batteries demands fundamental understanding, instrumentation, and multiphysics modeling for informed thermal management design. Further, growing interest in extreme conditions, like low-temperature environments or fast charging, exacerbate self-heating behaviors, drawing attention to local and global temperature variations.

This symposium provides a forum for tutorial, invited, and regular research presentations concerning all aspects of multiscale modeling, simulation, control, and design of electrochemical systems. Contributions related to both fundamentals and applications are encouraged. From this meeting onwards, the Electrochemical Engineering for the 21st Century symposium will be merged into this multiscale symposium. New electrochemical applications are being discovered where the control of events from molecular to macroscopic length scales is critical to product quality and process control. In addition, improvements in many existing technological systems are today based on understanding how to control electrochemical events occurring at near molecular length scales. Future trends in electrochemical engineering will be influenced by the need to control processes and ensure quality at the molecular scale. Transfer of molecular-scale understanding and discoveries into new and improved products and processes requires integration of system behavior across a range of length and time-scales. New engineering approaches are needed that couple traditional current and potential distribution approaches to molecular-scale events to accurately describe and design systems to meet the needs of the next century. For example, such an approach will open the way to exploiting self-assembly during processing.

The path from discovery, invention, and scientific understanding to well-engineered products and processes is complex and involves the 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 of molecular mechanisms, tailoring new materials, and integrating data over a wide range of scales to scale-up, design, and develop manufacturing methods able 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 symposium explores advances in fundamental and applied electrochemistry and electrochemical systems to enable efficient, economical, and sustainable hydrogen storage and release. For example, by utilizing electrochemical methods, hydrogen or electrical power can be directly stored into organic and non-organic carriers as protons (H+) and electrons (e-) without the need to manage hydrogen (H2) molecules. When the hydrogen (or power) is needed, the carriers are electrochemically dehydrogenated (i.e., oxidized) to release H+ and e- that can be used for electrochemical reductions, H2 evolution, or power generation. Hence, eliminating the need for the H2 storage and transportation infrastructure.

The hydrogen carriers can be derived from abundant and naturally occurring compounds such as carbon dioxide (CO2), nitrogen (N2), nitrates (NO3-), and bicarbonates (HCO3-). The hydrogen carriers of interest include, but are not limited to, alcohols, ammonia, bicarbonates, carboxylic acids, and ketones, as well as aromatic (un-) saturated renewable and fossil molecules.

Sustainable economic growth and high quality of life require an abundant supply of clean and affordable energy. Future energy sources include solar, wind, and nuclear—all of which can produce electricity as the primary form of energy. The conversion of this electrical energy to fuels (e.g., hydrocarbon or hydrogen) using common chemicals such as carbon dioxide and water through electrochemical processes (e.g., electrolysis reactions), provides an opportunity to remove the temporal variation in the energy supply from solar and wind energy. Electrolysis reactions may involve protons, hydroxide, oxide, or other ions. This Electrosynthesis of Fuels 7 symposium provides an international forum for the presentation and discussion of the latest developments on electrolysis and related topics. The emphasis of this symposium is on recent advances relevant to the conversion and utilization of CO2 and/or H2O for synthesis of fuels and other chemicals. The application of the same cells as fuel cells is of special interest because reversible cells that may be coupled with renewable or nuclear electric power production to increase efficiency through energy storage are of particular importance.

Papers are solicited on the topics as follows:

1. Electrolysis cells including electrolytes, electrodes, seals, and interconnects for the conversion of CO2 and H2O to fuels;
2. Solid oxide fuel cells and protonic ceramic fuel cells;
3. Electrocatalytic phenomena in oxygen electrodes and fuel electrodes;
4. Electrochemical and chemical technologies for CO2 separation;
5. Novel materials or concepts for CO2 conversion and capture.

In 2016, the United States Department of Energy launched the Energy Materials Network (EMN) to accelerate the process of materials discovery, development, and ultimate deployment in major clean energy sectors. Innovations in clean energy technologies are vital to domestic energy security and economic growth. Consistent with the EMN vision, moving transformational energy technologies forward requires an honest discussion of the challenges and opportunities in critical materials R&D. An integrated approach spanning materials design and synthesis through process scale-up and qualification is essential to this effort. This symposium brings together materials experts and stakeholders from multiple sectors covered in the current EMN portfolio. This includes world-class leaders with multi-physics and multi-scale expertise from the EMNs as well as leaders of other high impact materials initiatives in chemical and electrochemical systems for clean energy applications. Some common material challenges across all EMNs include interfaces, corrosion, performance, benchmarking, analysis, and computational modeling. It is expected that crosscutting conversations at this session foster synergy for future collaborations.

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.

Advances in materials manufacturing have provided new opportunities for exploring, developing, and implementing process technologies where complex thermodynamics, ionic transport, and chemistry can play a key role. With the inception of direct digital manufacturing (such as additive manufacturing and computer numerical control manufacturing), rapid laser processing, and AI-driven automated manufacturing, the ability for control and simulation of materials manufacturing is enabling materials and device manufacturing at higher rates, precision, and customization.

Advanced manufacturing has found the significant application of high-temperature materials and devices relevant to electrochemistry and energy conversion/storage. Many advanced manufacturing-related activities provide unique opportunities for a wide array of electrochemical energy conversion and storage, electrochemical membrane reactors, chemical sensors, high-temperature electrochemical processing, and high-temperature electrochemical materials.

When interfaces are formed in electrochemical systems, such as between a solid and a liquid or a solid and a solid, a wide range of energy storage and associated energy transfer properties can be designed. Examples include emergent electrocatalytic, photoelectrochemical, electrodeposition, and/or redox reactions. The properties that arise are inevitably through the electrically driven non-equilibrium interaction of ionic and electronic degrees of freedom at such interfaces. Despite the growth in applications and intensive ongoing research, the fundamental nature of atomistic and electronic processes driving interfacial electrochemical phenomena are not well understood due to the inherently far from equilibrium charge dynamics often present. To enable urgently needed performance enhancements in the aforementioned technologies, leading theoretical and experimental efforts seek to understand the interdependent correlation between ionic and electronic dynamics across solid-liquid and solid-solid interfaces at nanoscale and atomistic dimensionalities. Some examples include a deeper understanding of multi-step reaction kinetics at solid-liquid and solid-solid interfaces, including the intricate balance between ionic motion and electron transfer, as well as the role of non-equilibrium excitations due to light interactions and coupled driving electric fields arising under external bias potentials in electrocatalytic, photoelectrochemical, and electrochemical redox processes.

This symposium's primary focus is on gathering leading teams exploring the coupled relation between ionic and electronic transfer dynamics at solid-liquid and solid-solid interfaces, with an eye to coalescing contributions from characterization and modelling efforts at the frontier of addressing these crucial problems. The aim is to present leading examples over the full range of research from fundamentals to emerging energy technology applications. Invited speakers are drawn from diverse backgrounds in the characterization and modeling of electrochemical interfaces, with sessions organized to include an inclusive mixture of theoretical and experimental contributions. This grouping provides the broad platform necessary to offer a critical and timely assessment toward understanding and engineering electrochemical interfaces in energy systems, while offering the fertile environment needed to catalyze new interdisciplinary breakthroughs and collaborations.

1. Theory and modeling of structural, chemical, and electronic properties influencing energetic processes at solid-liquid and solid-solid interfaces;
2. Electronic and atomic structure characterization of electrochemical interfaces;

The symposium provides an interdisciplinary forum for the exchange of ideas and discussion of new results in research dealing with the fundamental aspects of such electrocatalytic processes as oxygen reduction and oxygen evolution (water oxidation) reactions in acid and alkaline media. Despite the massive research efforts both in fuel cell research (development of cathodes) and water electrolysis (development of anodes), one of the most important bottlenecks remains the sluggish kinetics of the O2-reduction and O2-evolution reactions. These problems, in addition to stability issues, hamper the widespread rollout of low-temperature fuel cells and water splitting electrolyzers.

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, as well as low-platinum-content, platinum-group-metal-free and surface-decorated and nanostructured systems, metal-organic-framework and core-shell type materials, nanostructured metal oxides, perovskites, distinct supports, together with carbon carriers (including graphene in simple and functionalized forms), molecular or metalloorganic materials including N4-transition metal microcycles, metal-Nx type catalysts, enzymes or their combinations, microbial biofilm-based layers and various hybrid systems. Among other important issues are modeling, simulation of operation, and evaluation of electrode systems for the electrocatalytic processes mentioned above, as well as discussion of related interfacial phenomena, selectivity (formation of undesirable hydrogen peroxide intermediate in oxygen reduction or selective generation of oxygen in seawater-type electrolytes). Special attention is paid to the improvement of stability and durability of catalytically active sites. Structure, morphology, reactivity, and methods of characterization of catalytic systems are of importance as well.

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 who are active in the areas mentioned above. During the symposium, we hope to outline important directions for the future.

Electrochemistry and photochemistry offer powerful analytical and synthetic tools. Combining them in synergetic manners provides unique access to new processes and unexplored phenomena that cannot be attained either electrochemically or photochemically. Therefore, photoelectrochemistry and spectroelectrochemistry have grown into new research fields with immense importance for energy science, synthesis, and materials engineering, among other areas of science and engineering. For decades, solar energy research, including light-driven water splitting, carbon dioxide reduction, and nitrogen fixation, has led to the development of photoelectrochemistry and spectroelectrochemistry. Recent photoelectrochemical synthesis of novel valuable compounds (that cannot be prepared any other way) has tremendously broadened the impacts of this field.

This symposium brings together:
1) Experts in solar fuels;
2) Physical chemists discovering mechanisms of photoelectrochemically driven phenomena;
3) Analytical chemists developing spectroelectrochemical methodologies;
4) Synthetic chemists using photoelectrochemical tools.

Presentations in spintronics and photoelectrochemical attainment of chirality are also solicited. In addition to the many ECS members working in this field, this symposium includes presenters who, while working in electrochemistry-pertinent areas, are not ECS members.

Typical electrochemical conditions are three electrodes (working, counter, reference) in liquid electrolyte near room temperature where potential or current is perturbed and current or potential is measured. However, new electrochemical perspective, theory, devices, and measurements arise where one or more of these conditions are modified. Papers are sought where one or more of the typical conditions are modified; or energy is input to the system under atypical conditions; entropy is purposefully increased or decreased; unusual gradients are established in the matrix or at the electrode electrolyte interface; otherwise, unreactive redox species are rendered electroactive. Papers that provide methods, models, data, devices, or novel notions are all of interest.
