Abstract Solid‐state Li‐ion batteries have emerged as the most promising next‐generation energy storage systems, offering theoretical advantages such superior safety and higher density. However, polymer‐based solid‐state face challenges across wide temperature ranges. The primary issue lies in fact that polymer electrolytes exhibit relatively low ionic conductivity at or below room temperature. This sensitivity to variations poses operating lithium sub‐zero temperatures. Moreover, elevated working temperatures lead shrinkage deformation, ultimately resulting battery failure.
