As the battery fails, the voltage drops to zero, and the anode and cathode short circuit. With all the battery''s stored energy flowing through the short, the temperature of the battery will quickly spike, to over 300°C. This causes smoke to be produced from inside of the battery. Smoke production is the first step in thermal runaway and
