ABSTRACT:
An electrolyte for use in rechargeable electrochemical cells having a lithium electrode and a depolarizer which includes an electrochemically active amount of LiAsF.sub.6 dissolved in tetrahydrofuran and a rechargeability improving amount of LiI contained therein to form an electrolyte solution, said solution being capable of passing through a molecular sieve of less than 5 Angstroms. A preferred embodiment includes a 1 molar solution of the LiAsF.sub.6 and from about 0.8 to 1.4 molar solution of LiI.
