Abstract
Abstract A battery embodying this invention comprises an anode including an anode-active material formed of one metal selected from the Group Ia metals or preferably lithium metal, a cathode including a cathode-active material formed of organic compounds having a pi -electron conjugated system, and an electrolyte prepared from a material which is chemically stable to the cathode and anode materials and permits the migration of the ion of the anode metal to the cathode for electrochemical reaction with the cathode-active material.
