Topic: Wide-temperature operation batteries and solid-state batteries

Over the past two decades, rechargeable batteries have achieved significant breakthroughs in energy density. The mainstream development directions of batteries in the future are solid-state batteries and wide-temperature operation batteries. However, traditional liquid electrolytes face severe challenges regarding safety and service life when operating outside the normal temperature range of –20 °C to 55 °C due to their chemical/electrochemical instability under harsh electrode reactions (highly oxidative environments) and temperature fluctuations. Replacing traditional liquid electrolytes with solid-state electrolytes completely mitigates risks such as electrolyte leakage and self-combustion. Solid-state batteries thus offer reliable energy storage solutions for applications requiring exceptionally high safety and energy density. Despite substantial progress and ongoing commercialization, further improvements in energy density and cycle life are still require improvements.

This Special Issue aims to explore recent advances in wide-temperature operation batteries and solid-state batteries. It seeks contributions addressing a broad range of topics, including anode and cathode materials, electrolytes (both liquid and solid-state), electrode/electrolyte interfaces, electrochemical mechanisms, advanced characterization methods, theoretical modeling, fabrication techniques, and the integration of these components into various rechargeable battery systems, such as lithium-ion, sodium-ion, potassium-ion, aqueous zinc batteries, and others. By bringing together materials scientists, chemists, physicists, and engineers from diverse backgrounds, the Special Issue provides a platform to exchange knowledge, identify research gaps, highlight emerging trends, and foster interdisciplinary collaboration, thereby accelerating the practical development of batteries capable of wide-temperature operation and solid-state batteries.
