Abstract:
In at least one embodiment, a battery is provided comprising an anode and cathode, a separator between the anode and cathode, and a shutdown layer between the separator and the anode or cathode. The shutdown layer may include low melting point material and a conductive material within the low melting point material forming a conductive network within the shutdown layer. At a melting point temperature of the low melting point material, the conductive network is reduced such that at least a portion of the shutdown layer is substantially electrically non-conductive. The shutdown layer may be a free-standing layer or may be coated one or both of the electrodes.
