Lithium batteries are alternatives to metallic lithium batteries that have appeared in recent years. Its anode uses a carbon electrode capable of absorbing lithium ions. During charging, the lithium atoms in the cathode are ionized into lithium ions and electrons. , and lithium ions move toward the anode and combine with electrons to form lithium atoms. During discharge, lithium atoms are ionized from the anode surface in the graphite crystal into lithium ions and electrons, and lithium atoms are synthesized at the cathode.
Detailed information:
Lithium metal battery:
Lithium metal battery generally uses manganese dioxide as positive electrode material, lithium metal or its metal alloy as negative electrode material, and uses anon-aqueous electrolyte solution from the battery.
Discharge reaction: Li+MnO2=LiMnO2
Lithium-ion battery:
Lithium-ion batteries generally use metal oxide alloy lithium as cathode material and graphite. as cathode material. Negative electrode materials, batteries using non-aqueous electrolytes.
The reaction that occurs on the positive charge electrode is
LiCoO2==Li(1-x)CoO2+XLi++Xe-(electrons)
On the negative charge electrode The reaction that occurs is
6C+XLi++Xe-?= LixC6
The total reaction of the rechargeable battery: LiCoO2+ 6C = Li( 1-x)CoO2+LixC6

The discharge principle of the lithium battery is as follows: when the lithium battery is discharged, the lithium atoms on the negative electrode will decompose into electrons and lithium ions, and the electrons will arrive through the external circuit. L'positive electrode, lithium ions will pass through the separator and reach the positive electrode. Here is some more information about lithium batteries: 1. Lithium battery is a rechargeable battery. ,2. The lithium battery consists of a positive electrode, a negative electrode, a separator and an electrolyte. ,Extended content: ,1. There are many types of positive electrodes of lithium batteries, the most common are ternary lithium batteries and lithium iron phosphate batteries. , 2. During charging, the lithium atoms on the positive electrode will decompose into electrons and lithium ions under the action of external power supply. In this way, the lithium ions will move to the negative electrode via the separator and the electrons will move to the negative electrode via the external circuit. Lithium ions arriving at the negative electrode will form lithium atoms after encountering electrons.
