Tailored Temperature‐Responsive Solvation Structures Enabling Ultra‐Wide‐Temperature Quasi‐Solid‐State Lithium Metal Batteries From −70°C to 60°C

ABSTRACT Gel polymer electrolytes are essential for high‐energy‐density lithium metal batteries (LMBs), but their practical applications are limited by poor low‐temperature kinetics and insufficient high‐temperature stability. Notably, the wide‐temperature design of solvation structures is critical for the stable operation of wide‐temperature gel polymer electrolytes (WTGPEs). Herein, we contrive a novel temperature‐responsive gel polymer electrolyte (TRGPE) by finely tuning the ion–dipole inter
