ABSTRACT:
A composite electrical battery including a primary electrochemical cell and a fully or partially discharged rechargeable electrochemical cell. The rechargeable electrochemical cell is electrically connected in parallel to the primary electrochemical cell. The open circuit voltage of the primary electrochemical cell is significantly lower than the open circuit voltage of the rechargeable cell when the rechargeable cell is fully charged. The self discharge rate of the rechargeable electrochemical cell after electrically connecting the rechargeable electrochemical cell to the primary electrochemical cell is less than a predetermined self discharge rate. The composite battery has an improved current delivery capability for an extended life span compared to the primary electrochemical cell by itself. A method is provided for forming such a composite electrical battery. The method includes providing a primary electrochemical cell, providing a fully or partially discharged rechargeable electrochemical cell, and electrically connecting the primary electrochemical cell in parallel with the fully or partially discharged rechargeable electrochemical cell to form the composite electrical battery. The self discharge rate of the rechargeable electrochemical cell after electrically connecting to the primary electrochemical cell is less than a predetermined self discharge rate for extending the useful lifespan of the composite battery.
