Abstract: A battery includes an enclosure, a battery management unit (BMU), a conductive trace including conductive particles disposed on a surface of the enclosure and electrically coupled with the BMU to form a closed-loop electrical path. The BMU is configured to detect a resistance in the closed-loop electrical path caused by a percolation of the conductive particles, and determine a swollen condition of the battery based on the resistance.
