由若干单个电池串联与并联起来,组成电池组,再加上电池的保护电路,就构成了一块笔记本电脑的电池。如果按照内部使用电池的种类来分,大多可分为镍镉电池、镍氢电池、锂电池、锂聚合物电池等。而镍镉电池、镍氢电池由于具有记忆效应,容量小等缺点正逐步被淘汰掉,锂离子电池具有容量大、体积小、重量轻、自放电率低等一系列优点目前已经成为笔记本电脑内置电池的主流。 By a number of individual batteries in series and in parallel to form a battery pack, together with the battery protection circuit, constitutes a laptop battery. If used in accordance with the type of internal battery points, most can be divided into nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, lithium polymer batteries. The nickel-cadmium batteries, nickel-metal hydride batteries because of the memory effect, small capacity and other shortcomings are gradually being eliminated, lithium-ion batteries with large capacity, small size, light weight, low self-discharge rate and a series of advantages have now become a laptop built The mainstream of the battery.
