      Researchers have designed a lithium-ion battery that contains a fire-extinguishing material, which is released if the battery gets too hot.研究人员设计鼓励一款自带灭火材料的锂离子电池,在电池过热时就会释放灭火材料Flame retardant triphenyl phosphate sits inside a shell within the electrolyte fluid. The shell melts when the temperature reaches 150C ,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. attempts to incorporate TPP inside batteries without the shell have hampered1 their performance.If a lithium-ion b it can result in a short circuit - which can lead to fire.In February 2016, National Transportation Safety Board issued a warning about lithium batteries in aeroplane cargo2, describing them as "a fire and explosion ignition source".
