美国科学家近日研发出一款自带“灭火器”的电池,难道这就是传说中三星手机的救星?
Researchers have designed a lithium-ion battery that contains a fire-extinguishing material, which is released if the battery gets too hot.
研究人员设计出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 (TPP) sits inside a shell within the electrolyte fluid. The shell melts when the temperature reaches 150C (302F), releasing the chemical compound. 阻燃材料磷酸三苯酯被外壳包裹着置于电解液中。当温度达到150摄氏度 In tests, battery fires were extinguished in 0.4 seconds.
在测试中,电池的火在0.4秒内就被扑灭了。
Lithium-ion batteries power many devices but are a known fire hazard.
许多设备都用锂离子电池,但是这种电池存在火灾隐患,也是人尽皆知。
The Stanford University research team's peer-reviewed paper has been published by the journal Science Advances.
斯坦福大学研究团队的这篇论文已经同行评议并发表在《科学进展》期刊上。
Previous attempts to incorporate TPP inside batteries without the shell have hampered their performance.
先前该研究团队试图将没有外壳包裹的阻燃磷酸三苯酯置于电池中,但是效果不佳。
