Over the last decades, lithium-ion batteries (LIBs) have successfully been adopted for powering electrical vehicles (EVs). However, to meet the challenges of further replacing the combustion engine vehicle with EVs, advanced LIBs or next-generation batteries with high energy, fast charging, low cost, better safety, and long cycle life must be developed.

To overcome technical challenges, an in-depth understanding of the structural changes of the cathode and anode materials in bulk and at the surface, the interactions between the electrode material and the electrolyte, the formation and functionality of the electrode/ electrolyte interface (SEI and CEI) on the anode and cathode, and the effects of the additives and the surface coatings are critically important. Since those remaining challenges are complicated, none of the single characterization tools can provide a clear answer, and it usually requires multiple strategies to provide comprehensive information in multi-modal/multi-scale approaches. In such circumstances in current battery research, the development and application of advanced characterization techniques are becoming increasingly important.

This symposium aims to be a platform for battery scientists and researchers to discuss recent advances in characterization techniques and share new ideas from them. The topics include, but are not limited to:

• In situ/operando synchrotron-based X-ray techniques such as X-ray diffraction (XRD), pair-distribution function (PDF), X-ray absorption spectroscopy (XAS), scanning/transmission X-ray microscopy to study fundamental reaction and degradation mechanisms of battery materials and interfaces/interphases;

• In situ TEM and 4D-STEM investigation on LIBs and next-generation batteries;

• Multi-modal/multi-scale approaches with combinations of multiple techniques to solve challenging issues in advanced LIBs and next-generation batteries.

As electric vehicles (EVs) continue to gain traction as sustainable transportation solutions, the demand for high-performance lithium-ion batteries becomes more prominent. The driving range, fast-charging capabilities, overall efficiency, and safety of EVs rely heavily on advancements in the choice of active materials, as well as electrode engineering for lithium-ion batteries. This symposium brings together scientists and researchers to discuss the latest developments in a range of areas, including cathode materials, anode materials, separators, and electrolytes, electrode engineering, and highlights new advancements in enabling advanced lithium-ion batteries.

Electrochemical electrode-electrolyte interface plays an important role in battery properties such as redox activity, physicochemical processes, charge transfer kinetics, lifetime, and safety. New electrolytes and understanding of the electrochemical processes at the interfaces for Li-ion and new Li metal chemistries are crucial for rational performance improvement. This symposium invites presentations that aim to (1) understand the interphase structure and dynamics at various spatial and temporal resolutions using modelling/advanced in situ/operando characterization techniques, and (2) predict strategies to stabilize the interfaces of high-voltage and high-capacity cathodes and Li metal anode. Topics of interest include, but are not limited to advanced cathodes, new electrolytes, and Li metal anodes with an emphasis on the electrode-electrolyte interphases (e.g., solid-liquid and solid-solid).

Rechargeable lithium-ion batteries (LIBs) have been successfully commercialized and are the most attractive power sources for mobile devices. Their market has also expanded to large-scale applications such as electric vehicles and energy storage systems for grid support, in which both energy density and safety requirements are crucial. Despite considerable enhancements in the performance of LIBs, frequent fire/explosion incidents have caused a lot of public concerns over the safety of current LIBs. Recently, the focus of interest has shifted to solid state batteries (SSBs) in which electrolytes are made up of Li+-conducting solid materials. The use of solid electrolytes with non- or reduced flammability can keep batteries safe even under harsh and abusive conditions. To realize advanced SSBs, it is necessary to develop highly conductive and stable solid electrolytes as well as composite electrodes with enhanced interfacial stability and optimized electronic/ionic conducting paths.

Lithium or Lithium-ion based rechargeable batteries are currently used as major power sources mostly in portable electronics, power tools, electric vehicles and energy storage systems. However, commercial Lithium or Lithium-ion based rechargeable batteries have unsolved difficult problems such as high cost, unsustainable lithium resource and safety issues. Therefore, the non-lithium-based rechargeable batteries based on alternative metal elements based on monovalent (Na+ and K+) or multivalent metal ions (Mg²⁺, Ca²⁺, Zn²⁺, Al³⁺, etc.) are regarded as promising candidates to replace the applications of lithium-ion batteries in the near future. Although research and progress is increasing rapidly on non-lithium-based batteries, several challenges still need to be overcome to become a practical and commercial reality.

Solid state electrochemical devices, such as batteries, fuel cells, membranes, and sensors, are critical components of technologically advanced societies in the 21st century and beyond. The development of these devices involves common research themes such as ion transport, interfacial phenomena, and device design and performance, regardless of the class of materials or whether the solid state is amorphous or crystalline. The intent of this international symposia series is to provide a forum for recent advances in solid state ion-conducting materials and the design, fabrication, and performance of devices that utilize them. Papers are solicited on all aspects of solid state ionic devices such as solid oxide fuel cells (SOFCs), solid oxide electrolysis cells (SOECs), solid state batteries and microbatteries, chemical sensors, supercapacitors, ion transport membranes, thermal energy converters, and electrochromic devices.

Seawater electrolysis is environmentally friendly and is gaining attention as an alternative to traditional ocean energy sources. It can contribute to mitigating problems such as air pollution and ocean acidification. In addition, seawater electrolysis technology can help reduce the cost of hydrogen production. Seawater electrolysis is often preferred over freshwater electrolysis due to resource abundance and sustainability. However, seawater electrolysis requires more energy input than freshwater electrolysis due to the higher concentration of salt in seawater. Additionally, the high salt content of seawater can lead to corrosion and other maintenance issues, which can increase the cost of seawater electrolysis systems. In this regard, an electrodialysis (desalination) process is often combined with seawater electrolysis. Another important application of seawater electrodialysis is in the production of chemicals and other materials. Seawater contains a variety of minerals and ions that can be extracted and used for a range of industrial processes. Electrodialysis can be used to separate these ions and minerals from seawater, allowing them to be used in a cost-effective and environmentally sustainable way. This symposium focuses on electrochemical ion separation including electrodialysis and capacitive deionization, electrochemical chlorination and aquatic chlorine chemistry, and selective electrolysis (oxygen and hydrogen evolution reactions) of saline water and seawater.

Papers are solicited on the following topics, but are not limited to:

1) Synthesis of anodes and cathodes including dimensionally stable electrodes, mixed metal oxides, carbon-based electrodes, boron-doped diamond electrodes;

2) Electrochemical ion separation processes of saline water for water-energy nexus;

3) Selective oxidation between chloride and water;

4) Ammonia synthesis and electrolysis;

5) Scaling-free or inhibitive cathodes for hydrogen evolution reaction;

6) Electrochemical redox reactions for production of value-added chemicals.

Electrocatalysis has over the last years transformed our energy landscape from a carbon-based to a sustainable society. Unfortunately, until today, electrochemical energy devices suffer from performance or selectivity issues which have been increasingly approached from a material and engineering perspective. At the same time, an increasing number of studies have reported the importance of tuning the chemical and physical characteristics of electrode-electrolyte interfaces. These are characterized by the formation of an electric double layer (EDL) at which all electrochemical processes take place. Our increased understanding about the EDL has led to macroscopic cell design concepts, such as the use of ionomers to increase the density of cations close to the electrode. Despite the significance of the EDL, many questions remain, as our knowledge in large part remains based on models with unverified assumptions. In addition, electrochemical reactions under confinement in nano-sized dimensions and their physicochemical characteristics are extensively studied due to their potential importance for various electrochemical energy systems.

The objective of this symposium is to bring together scientists and engineers whose goal is to increase our fundamental knowledge of the EDL and electrochemical reactivity under nano-confined conditions which link to electrocatalytic performance (activity/selectivity/stability) using state-of-the-art experimental and computational techniques. This symposium is seen as a platform for deep discussion of the connection between fundamental understanding and application in real systems. This comprises, for example, the effect of cations, anions, water structure, hydrodynamic and nanoscale phenomena, or design principles of electrocatalysis and its interface based on activity, stability, and selectivity.
