Liquid electrolyte composition comprising a salt, electrochemical cell comprising the electrolyte composition, salt, and use of the salt in the electrochemical cell

Abstract

The invention relates to a liquid electrolyte composition comprising a salt of formula (I) which has an anionic complex comprising three bidentate ligands. The complex comprises, as the central ion Z, tantalum or niobium ions. The invention also relates to an electrochemical cell comprising the liquid electrolyte composition, and to the salt. The subject matter of the invention is also the use of the salt in an electrochemical cell.
