Abstract
A rechargeable lithium cell is provided comprising a lithium anode, a litm intercalating cathode, and an electrolyte comprising a solution of a lithium salt such as LiAsF.sub.6 or LiAlCl.sub.4 in 24.4 mass percent 4-butyrolactone (4-BL) in dimethoxyethane (DME). The cell exhibits improved low temperature (-40.degree. C..ltoreq.t.ltoreq.0.degree. C.) performance and rate capability.
