锂电池是智能手机和平板电脑最常用的电源。然而,连续几起手机锂电池爆炸事件却让人胆寒。消防部门通过实验证实,锂电池一旦发生物理损伤就会发生膨胀、冒烟,尤其在沾水后,锂电池会释放出更多的热量。据了解,金属锂化学性质非常活泼,属于遇湿危险的物品,它遇水或潮湿空气会释放易燃气体。其实,锂电池出现发热或者燃烧现象主要是由短路和电流过大两种原因引起的,但对于手机来说,充、放电电流过大的情况几乎不会出现。所 Lithium batteries are the most commonly used power source for smartphones and tablets. However, several phone lithium cell bombings in a row has made people feel cold. Fire department confirmed through experiments that in the event of physical damage to the lithium battery will occur expansion, smoking, especially in the water, the lithium battery will release more heat. It is understood that the lithium metal chemistry is very lively, belong to wet dangerous items, it will release flammable gases with water or humid air. In fact, the lithium battery heating or burning phenomenon is mainly caused by short circuit and current is too large for two reasons, but for mobile phones, charge and discharge current is too large will not occur.
