Experiments have been conducted on a variety of lithium ion batteries to measure their energy output in thermal runaway. Techniques were developed to measure the internal energy release as decomposition of the battery takes place, and combustion energy that can arise from ignited battery gases released in runaway. A nitrogen bomb calorimeter was designed, constructed and utilized to measure the internal energy in runaway. Three techniques were examined for measuring the combustion energy: (1) the Cone Calorimeter, (2) the Oxygen Bomb, and (3) the using a Gas Chromatograph to measure combustion species. The results from these measurement techniques are discussed and compared to the literature for similar batteries. Results generally show for 18650 batteries that the energies in runaway depend on chemistry, decomposition tends to increase with the SOC and can exceed its electric energy by 2-times, while combustion energy can reach 6-times.

已经对各种锂离子电池进行了实验，以测量它们在热失控时的能量输出。开发了一些技术来测量电池发生分解时的内部能量释放，以及失控释放的点燃电池气体可能产生的燃烧能量。设计、建造并使用了氮弹量热仪来测量失控状态下的内能。测试了三种用于测量燃烧能量的技术：(1) 锥形量热计，(2) 氧弹，以及 (3) 使用气相色谱仪测量燃烧物质。讨论了这些测量技术的结果，并与类似电池的文献进行了比较。结果通常表明 18650 电池失控的能量取决于化学性质，
