US 2020/0006807 A1 · SOLID ELECTROLYTE, ELECTRODE, POWER STORAGE DEVICE, AND METHOD FOR PRODUCING SOLID ELECTROLYTES

Abstract

A solid electrolyte (10) of the present disclosure includes porous silica (11) having a plurality of pores (12) interconnected mutually and an electrolyte (13) coating inner surfaces of the plurality of pores (12). The electrolyte (13) includes 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide represented by EMI-FSI and a lithium salt dissolved in the EMI-FSI. A molar ratio of the EMI-FSI to the porous silica (11) is larger than 1.0 and less than 3.5.
