可充电电池是如何工作的?解释清楚

by Johannes

大多数遥控器、测量设备和其他小型电子产品都由可充电电池供电。我们向你展示充电电池是如何工作的,以及小型电力存储单元内到底有什么。

可充电电池如何工作–简单解释

  • 充电电池内部是一种液体,即电解质。此外,一个可充电电池包含两种不同类型的金属。
  • 电解液导致两种金属相互反应。两种金属之间存在电子交换。
  • 为了使用这种化学能源,你需要将电池插入遥控器,例如。连接两极使电子运动起来。
  • 电子的运动产生电能,用于操作我们的遥控器。另一方面,会产生热能,因此,当你长时间使用电池时,电池会发热。

锂离子电池如何工作

同时,所谓的锂离子电池被用于几乎所有设备。无论是智能手机、笔记本电脑还是数码相机,锂离子电池无处不在。

  • 电池负极的金属是石墨,锂被嵌入其中。二氧化钴锂被发现在正极。
  • 当电池连接到电源插座时,带正电的锂离子从正极移动到负极。如果你在一个设备中使用电池,电子就会被离子所吸收。
  • 带负电的离子然后回到正极,在这里再次被充电。
  • 这个过程是有限的。经过无数次的充电循环,并非所有的锂离子都能完全放电。这就是为什么可充电电池的运行时间也会在大约两到五年内减少,这取决于使用时间。
