Abstract
An electrolyte solution for use in rechargeable electrochemical cells having nickel substrate as working electrode and lithium counter electrode and an electrochemically active amount of LiAsF.sub.6 dissolved in dimethyl sulfite and a rechargeability improving amount of lithium carbonate, Li.sub.2 CO.sub.3, contained therein to form electrolyte solution, said solution being capable of passing through a molecular sieve of less than about 5 Angstroms has been developed. A preferred embodiment includes a one molar solution of the LiAsF.sub.6 and from about 0.07 to 0.14 molar solution of Li.sub.2 CO.sub.3. The electrolyte solution has 85-90 percent efficiency for cycling lithium on nickel substrate.
