LITHIUM-IODINE BATTERY HAVING COATED ANODE

摘要

A lithium-iodine cell comprising a cathode including a charge transfer complex of an organic donor compnenet and iodine, an anode including a lithium element having a surface operatively contacting the charge transfer complex material, and a coating on the lithium surface of an organic electron donor material, preferably but not necessarily the organic donor component of the charge transfer complex. The organic electron donor material preferably comprises polyvinyl pyridine polymer and in particular two-vinyl pyridine polymer. A solution of two-vinyl pyridine polymer in benzene is brushed onto the anode lithium surface and than exposed to a dessicant. A number of coating preferably are applied successively to provide a resulting or finished coating of increased thickness.
