Abstract

The battery includes an electrolyte activating one or more cathodes and one or more anodes. The electrolyte includes one or more mono[bidentate]borate salts in a solvent. The solvent includes a silane or a siloxane. The mono[bidentate]borate salt can include a lithium dihalo mono[bidentate]borate such as lithium difluoro oxalatoborate (LiDfOB).
