Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
THE METHOD OF PRODUCING AN ELECTRIC CURRENT COMPRISING THE STEPS OF PROVIDING AN ELECTROCHEMICAL CELL HAVING MOLTEN LITHIUM AS AN ANODE MATERIAL, A GASEOUS CATHODE MATERIAL SELECTED FROM THE GROUP CONSISTING OF IODINE AND BROMINE, A MOLTEN ELECTROLYTE WHICH IS THE REACTION PRODUCT OF SAID LITHIUM AND SAID CATHODE MATERIAL AND ANODE AND CATHODE ELECTRODE MEANS FOR ELECTROCHEMICALLY REACTING SAID LITHIUM AND SAID CATHODE MATERIAL, ELECTROCHEMICALLY REACTING SAID LITHIUM AND SAID CATHODE MATERIAL IN SAID CELL TO FORM SAID REACTION PRODUCT WITH THE DEVELOPMENT OF AN EMF, WITHDRAWING SAID REACTION PRODUCT TO A CATHODE MATERIAL REGENERATION MEANS, PASSING AN OXYGEN CONTAINING GAS UPWARDLY THROUGH SAID REACTION PRODUCT IN SAID REGENERATION MEANS WHEREBY FREE CATHODE MATERIAL IS LIBERATED FROM SAID REACTION PRODUCT, PASSING SAID FREE CATHODE MATERIAL WITH SAID GAS TO A SEPARATOR MEANS, AND SEPARATING SAID FREE CATHODE MATERIAL FROM SAID GAS WHEREBY SAID FREE CATHODE MATERIAL IS MADE AVAILABLE FOR RECONSUMPTION WITHIN SAID CELL.

Claim 3
Dependent Claim
125 words
IN A SYSTEM FOR PRODUCING ELECTRICAL ENERGY FROM THE ELECTROCHEMICAL REACITON OF LITHIUM AND A CATHODE MATERIAL SELECTED FROM THE GROUP CONSISTING OF IODINE AND BROMINE SAID SYSTEM COMPRISING LITHIUM STORAGE MEANS, ELECTROCHEMICAL CELL MEANS, CATHODE MATERIAL REGENERATION MEANS, AND CATHODE MATERIAL SEPARATION MEANS, THE IMPROVEMENT COMPRISING A CATHODE MATERIAL REGENERATION MEANS WHICH IS ADAPTED TO RECEIVE REACTION PRODUCT FROM SAID CELL AND COMPRISES A CHAMBER FOR THE COLLECTION AND CHEMICAL CONVERSION OF REACTION PRODUCT FORMED IN SAID ELECTROCHEMICAL CELL REACTION PRODUCT INPUT MEANS, FREE CATHODE MATERIAL OUTPUT MEANS AND CONVERSION GAS INLET MEANS WHICH CONVERSION GAS INLET MEANS IS LOCATED AT SUBSTANTIALLY THE LOWEST POINT OF SAID CHAMBER WHICH PERMITS MAXIMUM DISTRIBUTION AND DISSIPATION OF SAID GAS THROUGH SAID REACTION PRODUCT IN SAID CHAMBER.
Claim 4
Dependent Claim
