Low‑Temperature All‑Solid‑State Batteries (IMAGE)
Caption
- All-solid-state batteries (ASSBs) overcome the intrinsic limitations of liquid electrolyte based lithium-ion batteries, such as electrolyte freezing and sluggish ion transport, by utilizing non-freezing solid electrolytes with relatively stable ionic conductivity at sub-zero temperatures.
- Performance degradation in ASSBs under sub-zero conditions arises from interconnected factors, including suppressed Li-ion transport, increased interfacial resistance due to side reactions, and mechanical instability, such as contact loss and microcracking.
- Achieving robust low-temperature performance demands the combined advancement of materials design and system-level engineering.
