Abstract

The properties of polymer hosts and their interactions with lithium salt are critically important for the design of alternative polymer electrolytes for safe lithium battery applications. Herein, we report a poly(ionic liquid) host as a solid electrolyte platform and propose a different coordination mechanism manipulating lithium-ion diffusion compared with traditional polymer systems. Our finding provides a new strategy to develop high-performance polymer electrolytes for next-generation high-energy-density lithium-metal batteries.
