Abstract
A non-aqueous rechargeable electrochemical cell includes an electrolyte composition produced through the dissolution of a thermally stable lithium salt in a lactone solvent. The resulting cell has stable performance in a wide temperature range between −40° C. and 80° C. The resulting cell operates across this wide temperature range with a commercially acceptable capacity retention, power loss characteristics, and safety characteristics across this temperature range.
