Lithium ion battery work principle

　　Lithium ion batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metal lithium, and can be charged. Its safety, capacity, self -discharge rate and performance price ratio are better than lithium -ion batteries. Lithium ion battery refers to the general term with lithium ion embedded compounds as the positive electrode material battery.

　　When charging the lithium -ion battery pool, lithium ion is generated on the positive electrode of the battery, and the generated lithium ion is moved by electrolyte to the negative electrode. As a layered structure of the negative electrode, it has a lot of micropores. The lithium ion that reaches the negative electrode is embedded in the carbon layer micropores. The more lithium ion is embedded, the higher the charging capacity. Similarly, when the battery is discharged (that is, the process of using the battery), the lithium ion embedded in the negative carbon layer is removed and moved back to the right. The more lithium ion is back, the higher the discharge capacity.

　　Lithium ion batteries use carbon materials as the negative electrode, with lithium -containing compounds as positive electrodes. There is no metal lithium, only lithium ions. This is lithium ion battery. Lithium ion battery refers to the general term with lithium ion embedded compounds as the positive electrode material battery. The charging and discharge process of lithium ion batteries is the embedded and dehydration process of lithium ions. In the process of embedding and desequanation of lithium ions, it is accompanied by the embedded and dehydration of the volume electrons such as lithium ion (accustomed to expressed the embedded or dehydration of the positive pole, and the negative electrode is expressed by insertion or insertion). During the charging and discharge process, lithium ions are embedded/de -embedded and inserted between positive and negative electrodes, which are vividly called "rocking chair batteries".
