Battery with inbuilt ‘fire extinguisher’ developed

Researchers have designed a lithium-ion battery that contains a fire-extinguishing material, which is released if the battery gets too hot. Flame retardant triphenyl phosphate (TPP) sits inside a shell within the electrolyte fluid. The shell melts when the temperature reaches 150C (302F), releasing the chemical compound. In tests, battery fires were extinguished in 0.4 seconds. …
