Abstract: 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.

Abstract: 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.

Abstract: A system and method for charging a rechargeable, or secondary, battery including a series string of cells, includes a topology of charging sources that selectively provides charging current to cells that need to be charged, but avoids overcharging cells that are already charged above a predetermined voltage threshold. Based on individual cell voltage measurements, the charging current is controlled in a manner to direct charging current to the battery cell(s) needing charge until these cells are fully charged, and by-passes battery cells that are fully charged or become fully charged.

Based on individual cell voltage measurements, the charging current is controlled in a manner to direct charging current to the battery cell(s) needing charge until these cells are fully charged, and bypasses battery cells that are fully charged or become fully charged.

Abstract: 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 “out of family” batteries.
