Do you want to ask: Do the positive and negative electrodes of lithium batteries alternate? Not alternately.
The positive and negative electrodes of lithium batteries do not alternate, but are located at both ends of the battery. The lithium battery is a rechargeable battery. The positive electrode is made of lithium cobalt oxide, lithium manganese oxide and other materials, and the negative electrode is made of graphite and other materials.
During the charging process, lithium ions move from the positive electrode to the negative electrode and, after passing through the electrolyte solution, are deposited on the surface of the negative electrode to form lithium. metallic lithium. During the discharge process, lithium ions move from the negative electrode to the positive electrode, escape from the surface of the positive electrode after passing through the electrolyte solution, and returnto the material of the positive electrode.
The types of negative electrode materials used in lithium batteries are as follows.
1. Carbon negative electrode material: The negative electrode materials currently used in lithium batteries are mainly carbon materials.
2. Tin-based negative electrode materials: Tin-based negative electrode materials can be divided into two types: tin oxide and tin-based composite oxide.
3. Negative electrode materials at the nanoscale: carbon nanotubes and nanoalloy materials.
4. It is a nano-oxide material.
