Abstract (en)

[origin: WO8201442A1] Electrochemical cells having an anode containing lithium as the electrochemically active material, and a cathode, said anode and cathode being immersed in a substantially anhydrous electrolyte free from Lewis acids and sulphur dioxide and containing from 0.1M to saturation LiAsF<u6>u dissolved in a solvent mixture of propylene carbonate and acetonitrile wherein acetonitrile forms from 10 to 80% of the combined volume of acetonitrile and propylene carbonate, and said solvent mixture consists of at least 80% by volume acetonitrile and propylene carbonate with the balance, if any, being in the form of inert liquid material.
