Abstract

A rechargeable battery cell having a specific combination of anode, cathode and electrolyte formulation is provided. The electrolyte formulation includes an additive system and a salt system. The additive system includes a first additive containing a sulfonyl group, an anti-gassing agent, and a second additive. The salt system includes a lithium salt and a co-salt. The disclosed electrolyte formulation has reduced gassing and improved performance over a wide temperature range.
