Crosslinked solid electrolyte

Abstract

The present invention relates to a crosslinkable electrolyte formulation comprising at least: —a lithium salt or a mixture of lithium salts—a hydrocarbon molecule comprising two thiol functions—an unsaturated hydrocarbon molecule comprising two C═C double bonds—a crosslinking agent, said crosslinking agent being a molecule carrying at least three C═C double bonds; in which the [C═C double bond]/[thiols] molar ratio is of between 1 and 1.1. The invention also relates to a process for the preparation of a crosslinked solid electrolyte by means of said formulation, and also to the use of said crosslinked solid electrolyte as solid electrolyte of an all-solid-state Li-ion battery or as component of the positive (posolyte or catholyte) or negative (negolyte or anolyte) electrode of an electrochemical system.
