Abstract
An electrochemical cell for a lithium ion battery has an anode comprising a silicon-based active material, a cathode comprising a cathode active material, and a capacity compensating electrolyte comprising a linear sulfite-based solvent and a lithium imide salt. A molar ratio of the lithium imide salt to the linear sulfite-based solvent is between 1:5 and 1:1.
