Devices and circuits are evolving to implement brain-inspired neural systems and brain-like energy efficiency in silicon-based computing systems, novel materials processing, and devices and circuits. 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 co-design, and device and circuit co-design, 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.

The purpose of this symposium is to bring 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. The topics of this symposium include but are not limited to:

1. Local phenomenon driven by temperature;
2. Thermal management design;
3. Novel metrology: Instrumentation and calorimetry;
4. Extreme environments and safety implications;
5. Modeling (bridging scales);
6. Emerging chemistries.

This symposium is dedicated to the memory of our colleague and friend, Bruno Scrosati, whose passion, insight, and scientific rigor left an enduring impact on the field of electrochemical energy storage. Bruno was not only a visionary in battery research, but also a tireless advocate for innovation who challenged conventional thinking and inspired a generation of scientists. His contributions to The Electrochemical Society and to the advancement of post-lithium energy storage systems continue to shape the direction of the field.

This symposium traces the historical development of rechargeable batteries, beginning with early electrochemical cells, through the rise and dominance of lithium-ion technology, and into the emerging era of next-generation systems often grouped under the umbrella of “beyond lithium-ion batteries.” While lithium-ion batteries have revolutionized portable electronics and electric mobility, their inherent limitations in energy density, thermal stability, raw material availability, and end-of-life sustainability have sparked a critical need for alternative chemistries.

We will explore in detail the present state and future promise of systems such as lithium-sulfur, lithium-air, sodium-ion, magnesium and multivalent-ion batteries, solid-state batteries, and redox flow systems. Particular emphasis will be placed on the underlying electrochemical mechanisms, materials challenges, interfacial phenomena, and scalable manufacturing considerations. Bruno had a special interest in solid-state and sulfur-based chemistries, and the symposium will highlight some of his key contributions to these areas, as well as the ongoing work that builds upon his legacy.

The symposium also reflects on the broader challenges facing the transition to sustainable and secure energy storage, including supply chain resilience, lifecycle assessment, and integration into future energy infrastructures. In doing so, we hope to capture not only the scientific roadmap, but also the spirit of collaboration, curiosity, and persistence that Bruno brought to every endeavor.

By revisiting the past, assessing the present, and looking toward the future, this symposium aims to honor Bruno’s memory with a forward-looking vision—one that continues to push the boundaries of electrochemistry in pursuit of cleaner, safer, and more efficient energy storage technologies.

The growing demand for fast-charging and high-power energy systems, driven by the rise of electric vehicles, drones, eVTOLs, and portable electronics, calls for innovations in materials science. This symposium explores cutting-edge advances in materials design, synthesis, and characterization to enable next-generation batteries with rapid ion transport, high-energy/power densities, and stable cycling. We invite contributions on novel electrolytes, interfacial engineering, electrode architectures, and scalable manufacturing methods addressing challenges in electrochemical stability, thermal management, and charge performance. The symposium aims to foster interdisciplinary dialogue among researchers, scientists, and engineers from academia, industry, and government institutions. Attendees are encouraged to present experimental results, theoretical insights, and computational modeling studies highlighting breakthroughs in advanced materials and their integration within high-performance energy systems.

Topics of interest include but are not limited to:

• High ion-conductive electrolytes;
• Innovative electrode materials and architectures for rapid charge kinetics;
• Thermal and electrochemical stability under high-power conditions;
• Advanced characterization techniques for fast charging phenomena;
• Integration strategies for optimizing energy systems.

High-energy-density rechargeable lithium- and sodium-ion batteries have garnered significant attention in response to the growing demand for portable electronics, electric vehicles, and large-scale grid storage systems. Despite their potential, these battery technologies face persistent challenges including limited cycle life, sluggish ion diffusion kinetics, structural instability, safety concerns, and high production costs. To address these issues, researchers are developing advanced materials, innovative battery architectures, and improved manufacturing processes.

Among the critical factors influencing battery performance is the electrolyte–electrode interphase (EEI), which plays a pivotal role in determining cycle life, ion transport kinetics (especially relevant to fast charging), and overall safety. In recent years, substantial progress has been made in rational interphase design and electrolyte solvation engineering to mitigate interfacial degradation and improve long-term stability. Additionally, integrated strategies—such as surface engineering of electrodes and electrolyte formulation—have shown promise in enhancing interfacial compatibility and full-cell performance.

This symposium aims to provide a collaborative platform for researchers and industry professionals to share recent advancements in interfacial science and spark new ideas in electrolyte and interphase engineering. Topics of interest include but are not limited to:

• Development of novel electrolytes and functional additives;
• Interface/interphase formation and modification strategies;
• Advanced characterization techniques of interfacial processes;
• Theoretical modeling and mechanistic studies of interphases;
• Electrolyte-electrode compatibility in full-cell configurations.

We welcome contributions that offer innovative insight into designing robust interphases and electrolytes for high-performance, long-life rechargeable batteries.

This symposium focuses on the translation of materials into manufacturable electrodes and cells, with emphasis on scalable synthesis routes, process–structure–property control, slurry and coating rheology, drying and densification strategies, interface quality and stability, and in-line metrology, data analytics, and quality assurance. We are interested in all battery materials and cell chemistries, including active and inactive components across different battery chemistries. We particularly encourage pilot line case studies that reveal what survived scale-up and what did not, including lessons on cost models, variability control, reliability testing, and circularity and reuse. Contributions on digital twins, ML-assisted process optimization, and standards and benchmarking that enable reproducible outcomes are welcome. Contributions from other steps of the supply chain are also welcomed, for example, raw materials processing.

The amount of research focusing on materials and cell design for solid-state batteries (SSB) is exponentially increasing. This proliferation is due to the theoretical gain in specific energy, energy density, energy efficiency, and safety. Even after a decade of intense research into many materials for solid ionic conduction, metal anode development, and cathode processing, a uniform agreement on the best material and interfacial design to scale up SSB is still lacking. One reason is that each material requires particular processing and device assembly strategies for testing, which make direct comparisons between literature results and nontrivial research groups. Running in parallel is the wide range of critical properties that control the ionic/electronic transport that occur across multiple length scales governed by multi-physics (electro-chemo-mechanics) variables. Therefore, there is a great need for efforts to develop and demonstrate practical testing procedures that will catalyze novel, well-informed hypothesis generation/testing and realization of commercial high-energy-dense SSBs.

This symposium focuses on efforts to design and implement benchmarking protocols in the synthesis and processing of materials into SSB. It covers the latest progress in: (1) materials characterization; (2) battery cycling performance; and (3) dendrite suppression.

• Transport analysis;
• Robust cell design;
• Ion diffusion and charge transfer kinetics in electrode materials and interfaces for SSBs;
• Investigations into electro-chemo-mechanics stability at interfaces;
• Dendrite suppression;
• Computational modeling of transport phenomena in materials and interfaces;
• Advanced characterization that aids in benchmark validation.

Electrodeposition is a facile method for fabricating materials and thus finds many applications. From energy storage to semiconductors, and from batteries to corrosion protection, the applications of electrodeposition are boundless. But these applications continually require innovations in the array of materials that electrodeposition can effectively fabricate. In this context, electrodeposition faces numerous hurdles that must be overcome.

This symposium includes the presentation of the Industrial Electrochemistry and Electrochemical Engineering Division New Energy Technology (NET) Award.

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, designing, and developing 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.

Of interest are engineering methods that have emerged from diverse applications such as nano-bio-micro-devices, photovoltaic converters, electrolysis, batteries, biomedical devices, etc. Such methods might include examples of exploratory work that targets the need for detailed fundamental understanding down to the molecular level; methods for early establishment of engineering goals for a proposed product; methods that are able to guide optimal performance in conversion when using renewable, “crude” feeds; examples of manipulating solution chemistry and electrochemical cell materials to meet production realities; methods for guiding discovery of novel materials and predicting their interactions with other cell components; development of process control methods for ensuring quality at the atomic scale; mathematical modeling of continuum and/or stochastic behavior of cell components as well as entire systems including prediction of behavior at multiple scales; estimating unknown parameters, quantifying uncertainty, and linking the pieces to optimize an overall system.

This symposium explores advances in fundamental and applied electrochemistry and electrochemical systems to enable economical, efficient, and safe energy and hydrogen storage and release. For example, by using electrochemical methods, electrical power can be directly stored in organic and inorganic carriers as protons (H+) and electrons (e-) at the cathode rather than molecular hydrogen (H2). When hydrogen or power is needed, the carriers are electrochemically dehydrogenated (i.e., oxidized) at the anode to release H+ and e- that can be used for electrochemical reductions, H2 evolution, or power generation at the cathode, thereby eliminating the need for the H2 storage and transportation infrastructure.

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

Electrosynthesis of fuels provides a powerful means to convert readily available molecules such as CO2, H2O, N2, or conventional energy sources (e.g., natural gas, solid carbon, etc.) into energy-intensive fuels and valuable chemicals through electrochemical reactions. Electrosynthesis of fuels represents an important step toward modernizing the chemical and energy industry, which emphasizes precision, efficiency, and resilience without depending solely on one energy source. This Electrosynthesis of Fuels 10 symposium provides an international forum for the presentation and discussion of the latest developments in electrolysis and related topics.

The feasibility of performing nitrogen electroreduction reaction, or nitrogen fixation, both in aqueous and non-aqueous solutions, constitutes an attractive prospect to produce ammonia under ambient, or near ambient, conditions. Development of durable, specific, and reasonably efficient, low-cost catalysts remains a great challenge for electrochemical science and technology. Currently, most electrochemical approaches to N2-fixation suffer from slow kinetics due to the difficulty of achieving the appropriate adsorption and activation of dinitrogen leading to cleavage of the strong, triple N≡N bond. Alternatively, the moderate dissociation energy of the N=O bond in nitrate anion (NO3–) makes it an alternative choice to N2 because it promises better kinetics for NH3 production. Experimental conditions, including a choice of solvent and electrolyte, its acidity, as well as the presence of certain cations and anions are of importance as well. In the case of N2-reduction, low yields and possibility of contamination require rigorous procedures and careful analytical approaches. For example, a promising approach to synthesize NH3 involves lithium- or calcium-mediated reduction of nitrogen in organic solvents. Ammonia is not only the second largest chemical produced in the world after sulfuric acid but is also a promising candidate for transporting and storing hydrogen due to its notable energy density. In this respect, the NH3-oxidation electrolysis offers a promising environmentally friendly approach to generate H2 at ambient temperature using suitable catalysts.
