电池工作的原理和“热失控”
要了解电池安全问题，我们需要了解电池的工作原理。电池有两个电极，其中一个电极上有正电离子，被称为阴极。阴极是存储“燃料”的地方，里面充满锂元素。另一个电极上有负电离子，称为阳极。
在充电的时候，锂离子从阴极移动到阳极。而在使用电池的时候，锂离子从阳极移动到阴极。在阴极和阳极之间的化学物质称为电解质，它可以帮助电离子移动，传导电流，目前的电解质主要是液态的（后文会提到固态电解质）。虽然电离子需要从一个电极移动到另一个电极，但两个电极本身不能接触。所以电池制造商在阴极和样机之间插入了隔板。
“现在的隔板做得真的很薄，这样电池也就能更加纤薄。” 电池设备制造商CADEX的创始人和首席执行官布赫曼（Isidor Buchmann）说。
而Galaxy Note 7电池的问题就是隔板存在缺陷，没能正确隔开两个电极。“这是最糟糕的情况之一，因为电池很有可能起火甚至爆炸。” 亚彻说。
电解质本身不太稳定，电离子在其中的移动也带来了不稳定性。当有大量的热量产生时——无论是通过两个电极互相接触还是仅仅因为外部过热——电解质可能会与其他化学物质发生反应，产生气体，释放更多的热量。随着化学反应的反复发生，气体以越来越快的速度释放越来越多的热量。这个过程将产生“热失控”，并可能导致起火燃烧。
这就是为什么很多手机在过热时会自动关机的原因。不过电池爆炸也可能是其他原因引起的。电池过度充电或充电过快，都有可能导致电池起火或者爆炸。
