The separator (106) also reduces unwanted diffusion of sulfur species.
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.
An improved cathode suitable for lithium-sulfur batteries, a battery including the cathode, and a battery including a separator containing inorganic fillers are disclosed. The cathode includes sulfur and a metal oxide and optionally includes an additional polymeric material. The metal oxide reduces dissolution of sulfur at the cathode and reduces sulfur-containing deposits on the battery anode, thereby providing a battery with relatively high energy density and good partial discharge performance. The separator also reduces unwanted diffusion of sulfur species.
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.
