A biasing mechanism for pressurizing an electrolytic solution of a reserve battery cell, the biasing mechanism containing a compressed spring and a trigger operatively associated with the compressed spring. The trigger is configured to release the compressed spring to pressurize the electrolytic solution.

Activation mechanism for a reserve battery cell

The present disclosure relates generally to indicating an end of life condition of an electrochemical device, and more particularly to systems and methods for sensing and determining an end of life condition in a cell comprising a high capacity cathode material suitable for use in a non-aqueous electrochemical cell. The high capacity cathode material has an amorphous or semi-crystalline form of copper manganese oxide, and optionally fluorinated carbon. The present disclosure additionally relates to transmitting the determined end of life condition to a user or monitoring device of the cell.

End of life indication system and method for non-aqueous cell having amorphous or semi-crystalline copper manganese oxide cathode material

An activation mechanism for a reserve battery cell generally includes a housing with a chamber containing an electrolytic solution and a delivery device configured to discharge the electrolytic solution from the housing. The delivery device includes a compressed spring configured to be released in response to an external force to initiate the discharge of the electrolytic solution from the housing.

The present invention generally relates to a thermal battery testing apparatus and a method for testing a thermal battery. The method includes one or more of the following steps: connecting the thermal battery in series with a resistance; connecting the thermal battery and resistance in series with a sinusoidal voltage source; applying a sinusoidal voltage to the thermal battery, measuring an impedance, reactance and/or capacitance across two terminals of the thermal battery, comparing the measured impedance, reactance and/or capacitance to a reference impedance, reactance and/or capacitance; and indicating whether the tested thermal battery is 'in family' or 'out of family.' The battery testing apparatus may include a testing device configured to apply a sinusoidal voltage to the thermal battery and to measure the impedance, reactance and/or capacitance across two terminals of the thermal battery. The testing apparatus may further be configured to report &#x201c;out of family&#x201d; batteries.
