Abstract (en)

[origin: US2024347772A1] A liquid electrolyte composition for an electrochemical cell is provided. The liquid electrolyte composition includes the following components: (A) sulfur dioxide; (B) at least one salt containing an anionic complex with at least one bidentate ligand. The ligand along with a central ion Z of the anionic complex forms a five to eight-membered ring containing a sequence of 2 to 5 carbon atoms, said sequence being optionally interrupted by a heteroatom.
