The working principle of lithium battery is also the principle of lithium battery charging and discharging, that is, the process of embedding and de-embedding of lithium ions. When charging, the positive electrode of the battery lithium ion generation occurs, these lithium ions in the electrolyte under the action of the negative electrode, move. When the battery is discharged, the negative carbon layer embedded lithium ions and shedding and then turn back to the positive electrode. In order to make it easier for you to understand the working principle of lithium batteries, here I popularize it for you.

I: the meaning of lithium battery

Lithium battery is a kind of non-aqueous electrolyte, lithium metal or lithium alloy as the positive and negative materials of the battery. Because the chemical properties of lithium metal is more active, it is often used in industry, environmental protection, etc., and is also the more mainstream battery type today.

Lithium metal batteries are usually batteries with manganese dioxide as the positive electrode, lithium metal or its alloy as the negative electrode, and use non-aqueous electrolyte for grouping. The discharge reaction of lithium batteries is actually the Li+MnO2=LiMnO2 chemical expression. Lithium batteries are characterized by extremely low self-discharge rate, smooth discharge voltage, and long service life, so they are often used in the manufacture of digital products, watches, and other processes.
