Getting to know the '' ghost'' inside batteries
The team determined that the batteries were experiencing soft-shorts, which are tiny, temporary short-circuits. With a soft-short, lithium filaments grow from the anode to the cathode. But the amount of growth is smaller than in a permanent short-circuit. While some electrons stay inside the battery, others might flow to an external device.
