两种电池成分介绍


锂电池


一般采用含有锂元素的材料作为电极的电池,现阶段负极最多的都是采用石墨。其实锂电

池主要依靠锂离子在正极和负极之间移动来工作。在充放电过程中,Lj+在两个电极之间往

返嵌入和脱嵌:充电池时,Li+从正极脱嵌,经过电解质嵌入负极,负极处于富锂状态;放

电时则相反。 


铅酸电池

铅酸电池的电极主要由铅及其氧化物制成,电解液是硫酸溶液。铅酸电池荷电状态下,正

极主要成分为二氧化铅,负极主要成分为铅:放电状态下,正角极的主要成分均为硫酸

铅。


Introduction of two battery components


lithium battery


Generally, batteries containing lithium elements are used as electrodes. At this stage, the most negative electrodes are graphite. In fact, lithium batteries

The cell works primarily by the movement of lithium ions between the positive and negative electrodes. During the charging and discharging process, Lj+ moves between the two electrodes to

Re-intercalation and de-intercalation: When charging the battery, Li+ is de-intercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state;

The opposite is true for electricity.


Lead-acid batteries

The electrodes of lead-acid batteries are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. Under the state of charge of the lead-acid battery, the positive

The main component of the pole is lead dioxide, and the main component of the negative pole is lead: in the discharge state, the main component of the positive angle pole is sulfuric acid

lead.
