Shenzhen Sinoli Electronic Co.,Ltd | Updated: Jan 07, 2018

what's the thermal runaway of 18650 battery?

take 18650NMC (Li (Ni0.45 Mn0.45 Co0.10) O2) battery for example, in the thermal runaway test shows the process of core temperature and surface temperature viriation. 

when the heating rate is low, so the core temperature and the surface temperature of the battery is very close, but when the temperature rises to a certain temperature, generally after being cycled for 1200times, the adverse reactions occur, so the core temperature to 1000 degrees Celsius, far higher than the surface of the battery temperature.

suggestion: do not mount 18650 batteries without expert knowledge and experience.
