摘要

A new experimental technique was developed for the measurement of energetics of a thermallyinducedrnbattery failure. This technique, here referred to as Copper Slug Battery Calorimetry (CSBC), wasrnemployed to investigate a widely utilized lithium ion battery of 2200 mA h capacity at various states ofrncharge (SOC). It was shown that this technique yields time and temperature resolved data on the rate ofrnheat production inside a failing battery. The total energy generated inside the battery was found tornincrease with increasing SOC to the maximum value of 34.0±1.8 kJ. To capture the energetics of flamingrncombustion of the materials ejected from the battery, CSBC was coupled with a cone calorimeter, whichrnmeasures heat released in a non-premixed flame using the principle of oxygen consumption. Thernmaximum amount of energy released by the battery as a results of flaming combustion of its materialsrnwas found to be 97.5±12.4 kJ.
