An artificial solid interphase with polymers of intrinsic microporosity for highly stable Li metal anodes

Polymers of intrinsic microporosity (PIM-1) have an appropriate pore size to reduce the solvation number of Li ions in electrolytes. This unique pore structure of PIM-1 as a solid interphase can suppress transport of solvent and consequently unwanted chemical reactions at the interface of anodes, thereby extending the cycle life of Li metal anodes.
