Title:
SOLID ELECTROLYTE, ELECTRODE, ELECTRICITY STORAGE ELEMENT AND METHOD FOR PRODUCING SOLID ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2019/088197
Kind Code:
A1
Abstract:
A solid electrolyte (10) according to the present disclosure is provided with: a porous silica (11) which has a plurality of pores (12) that are connected with each other; and an electrolyte (13) which covers the inner surfaces of the plurality of pores (12). The electrolyte (13) contains 1-ethyl-3- methylimidazolium bis(trifluoromethanesulfonyl)imide which is expressed as EMI-TFSI and a lithium salt which is dissolved in the EMI-TFSI. The molar ratio of the EMI-TFSI to the porous silica (11) is more than 1.5 but less than 2.0.
