Abstract
Abstract 1 to 2 mol dm -3 LiAsF 6 in dimethylcarbonate or 1 to 2 mol dm.su3 LiAsF 6 in dimethylcarbonate mixtures with methyl formate in which the mass percent of the dimethylcarbonate compound can vary from 25 mass percent to 100 mass percent is used as the electrolyte in a lithium rechargeable electrochemical cell. The cell also includes lithium as the anode and a lithium intercalating compound as the cathode.
