Title:
SOLID ELECTROLYTE, ENERGY STORAGE DEVICE, AND METHOD FOR PRODUCING SOLID ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2020/203075
Kind Code:
A1
Abstract:
The present invention provides a plastic-crystal solid electrolyte having high ionic conductivity, and an energy storage device in which the solid electrolyte is used. The plastic crystal includes two different anions selected from the group consisting of: various amide anions in which an NH2 anion is substituted by a perfluoroalkylsulfonyl group, a fluorosulfonyl group, or both of these groups; and tris(trifluoromethanesulfonyl)methanide anions. Alternatively, the plastic crystal includes two anions selected respectively from: the first group mentioned above; and a second group that includes hexafluorophosphate anions, various perfluoroalkylphosphate anions in which some fluorine atoms in PF6 are substituted by fluoroalkyl groups, and various perfluoroalkylborate anions in which some fluorine atoms in BF4 are substituted by fluoroalkyl groups.
