摘要： 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.

摘要： A rechargeable battery is designed with cells having a specific combination of anode, cathode, and electrolyte compositions to maintain long cycle life at extreme high temperatures and deliver high power at extreme low temperatures. These properties can significantly reduce or altogether eliminate the need for thermal management circuitry, reducing weight and cost. Applications in telecommunications backup, transportation, and military defense are contemplated.
