Battery with inbuilt 'fire extinguisher' developed

By Zoe Kleinman
Technology reporter, BBC News

From the section Technology
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. Lithium-ion batteries power many devices but are a known fire hazard.
The Stanford University research team's peer-reviewed paper has been published by the journal Science Advances.
