Nano‐Crosslinked Polyether‐Based Gel Polymer Electrolytes for Interface‐Stable High‐Voltage Lithium‐Ion Batteries
Gel polymer electrolytes hold practical promise for high‐energy‐density and safe lithium‐ion batteries. However, the use of solvents always compromises mechanical strength and triggers undesirable interfacial side reactions. Herein, a two‐step strategy involving triethoxysilylation of polyethylene glycol (PEG) and...
