Claim 1
Independent Claim
134 words
THE METHOD OF GENERATING ELECTRIC POTENTIAL AT TEMPERATURES LESS THAN THE MELTING POINT OF LITHIUM WHICH COMPRISES DIRECTING NITROGEN, AND, AT LEAST INITIALLY MOISTURE, AGAINST THE SURFACE OF A SOLID LITHIUM BODY HAVING A RELATIVELY LOW SURFACE-TO-VOLUME RATIO AND HAVING A CATHODE COLLECTOR IN SAID BODY CLOSE TO SAID SURFACE AND AN ANODE COLLECTOR IN SAID BODY REMOTE FROM SAID SURFACE UNTIL THERE IS FORMED ON SAID SURFACE AN OUTER LAYER OF LITHIUM HYDROXIDE AND AN UNDERLYING LAYER OF POROUS LITHIUM NITRIDE IN WHICH IS SAID CATHODE COLLECTOR BUT WHICH DOES NOT CONTACT SAID ANODE COLLECTOR, AND THEREAFTER CONTINUING TO DIRECT NITROGEN AGAINST SAID BODY WHEREBY NITROGEN DIFFUSES THROUGH SAID OUTER LAYER OF LITHIUM HYDROXIDE AND INTO SAID POROUS LITHIUM NITRIDE THEREBY CONTACTING SAID CATHODE COLLECTOR AND CONVERTING ADDITIONAL LITHIUM METAL TO LITHIUM NITRIDE.
