The active Li⁺ was coordinated with the zwitterionic part (squaric acid) of HUT4 by mechanical grinding to prepare a metal covalent organic framework HUT4Li, which was used as the filler of PEO and PPC composite polymer electrolytes (CPEs). The Li⁺ on the surface of HUT4Li can bind to oxygen atoms in PEO and PPC substrates as Lewis acid sites to pr...
