摘要： A rechargeable electrochemical cell is provided having a pressure-responsive apparatus for determining a charge termination point. In particular, a reversible pressure-responsive switch may be disposed in a cap at the open end of a rechargeable metal hydride cell. The reversible pressure-responsive switch may also contain a vent system for releasing the cell internal pressure. Alternatively, a rechargeable cell may include a strain gauge disposed in its outer surface whose resistance changes as the outer surface of the battery expands due to internal pressure accumulation during charging. Additionally, a rechargeable cell is used combination with a charging source that can supply constant voltage, constant current, alternating current, or voltage that varies between a minimum threshold and a maximum threshold.

摘要： An electrochemical cell is provided having a cathode can that fits over an anode can to define an anode cavity for retaining active anode material. A cathode assembly is disposed proximal the base of the anode can, and is separated from the anode cavity via a separator. A radial seal is provided at the remote region between the outer periphery of the anode side wall and cathode side wall to prevent the leakage of electrolyte material. An insulator is disposed between the anode and cathode to provide electrical insulation therebetween.
