Abstract

All-solid-state lithium-ion batteries (ASSLBs) have garnered significant attention due to their superior safety performance and high energy density, making them a promising next-generation energy storage technology with broad application potential. However, their performance is significantly affected by temperature extremes. At low temperatures, ion transport is hindered, leading to severe battery polarization. Conversely, at high temperatures, internal side reactions and phase transitions are exacerbated, which accelerates material degradation and thermal failure. These challenges limit the development and widespread adoption of ASSLBs. Therefore, expanding the operational temperature range of ASSLBs is essential for their commercial viability. This review systematically examines the impact of temperature changes on the performance of electrode materials, solid-state electrolytes (SSE), and interfaces of ASSLBs, especially describing the Li⁺ transport mechanisms at different components and the thermal failure mechanisms of materials. Subsequently analyses and ponders the current challenges and solutions in this field. Finally, future research directions for enhancing ASSLBs performance under extreme temperatures are proposed.
