Abstract:
1. A separator assembly for a battery that includes an anode and a cathode, the separator assembly comprising: a porous film that has a first end and a second end opposite the first end; first and second rollers; and a sensor configured to determine a performance of the porous film, wherein the sensor is positioned between the porous film and one of the cathode and the anode and is configured to generate an output associated with the performance of the porous film; wherein a portion of the porous film that includes the first end is wound on the first roller and the second end is coupled to the second roller, wherein the first roller is configured to rotate to unroll the porous film; and wherein the second roller is operative to rotate to move the porous film relative to the anode and the cathode based on the output of the sensor.
