New approach to self-extinguishing Li-ion batteries: temperature-responsive fire-extinguishing microcapsules
Green Car Congress
JULY 21, 2015
Researchers at the Advanced Batteries Research Center of the Korea Electronics Technology Institute have developed lithium-ion batteries with a self-extinguishing capability for improved safety by integrating temperature-responsive microcapsules containing a fire-extinguishing agent in the cell. The microcapsules release the extinguisher agent upon increased internal temperature of a battery cell, resulting in rapid heat absorption through an in situ endothermic reaction and suppression of furth
