The basic construction of lithium ion battery includes a positive electrode, a negative electrode, an electrolyte, and a diaphragm. Positive electrode materials are usually lithium-containing compounds, such as lithium cobaltate, lithium manganate, lithium iron phosphate, etc.; negative electrode materials are mostly carbon materials, such as graphite, etc.; electrolyte is an important part of lithium batteries, which can conduct lithium ions, so that the battery can be charged and discharged normally; the diaphragm is located in the positive and negative poles between the positive and negative poles, to play a role in isolating the positive and negative poles, preventing short circuits.
The charging and discharging process of lithium ion battery is actually the embedding and de-embedding process of lithium ions. During charging, lithium ions in the positive electrode material move to the negative electrode through the electrolyte and are embedded in the micropores of the negative electrode material; while during discharging, lithium ions embedded in the negative electrode material move back to the positive electrode through the electrolyte. This process is accompanied by the embedding and de-embedding of electrons equivalent to lithium ions, thus realizing the charging and discharging of the battery.
