随身听、笔记本电脑等小型电器都使用充电电池,其中大部分使用锂电池。锂电池是通过锂离子电解液移动两极间进行充放电的电池。一般是将电池放入形状为圆型、角型的金属容器中,像笔记本电脑等将几个电池放在一个盒子里使用。自1998年以来,电解质替代了以前的液体,锂聚合物电池开始上市,像笔记本电脑、电子书等较薄的随身携带电器都使用这种药片型电池。锂聚合物电池与之前的同等大小的充电电池相比,其容量更高、输出电 Small players such as music players and laptops use rechargeable batteries, most of which use lithium batteries. Lithium battery through the lithium-ion electrolyte to move between the two poles charge and discharge batteries. Usually the battery into the shape of a round, angular metal container, such as a laptop, a few batteries in a box to use. Electrolytes have replaced previous fluids since 1998, and lithium-polymer batteries are on the market and are being used on thinner portable devices like laptops, ebooks and the like. Lithium polymer battery with the same size before the rechargeable battery compared to its higher capacity, the output power
