The advantages of 26650 lithium-ion battery and the principle of charging and discharging

1. High energy density and low self-discharge rate. The capacity of 26650 lithium-ion batteries is 1.5-2 times that of nickel-hydrogen batteries of the same quality. At the same time, the internal resistance of domestic 26650 lithium-ion batteries is less than 60m, which greatly reduces the battery's capacity. Self-consumption, which can extend the service life of the battery while extending the use time. 2. Stable charge and discharge performance. 26650 lithium ion battery has no memory effect, does not decompose when exposed to heat, has high safety performance, and has a long life cycle. 3. High voltage 26650 Li-ion battery voltage is generally above 3.6 or 3.7V, much higher than nickel-chromium and nickel-hydrogen batteries. 4. It can be used in series or in parallel to form a 18650 lithium ion battery pack. 5. Environmentally friendly and pollution-free 26650 lithium ion battery charging and discharging principle 26650 lithium ion battery can be charged and discharged because of the movement of active lithium on its positive electrode. That is: when the battery is charged, active lithium is generated on the positive electrode of the lithium ion battery, moves to the negative electrode, and is embedded in the layered structure of the negative electrode. The material system of the negative electrode is graphite, which is carbon with a layered structure. It has many micropores. When lithium moves to the negative electrode, it will be embedded in the micropores. The more lithium embedded in the micropores, the higher the charging capacity. In the same way, when the battery is discharged, the lithium embedded in the carbon layer of the negative electrode is released and moves to the positive electrode. The more lithium that returns to the positive electrode, the higher the discharge capacity. The capacity of the 26650 lithium-ion battery that we usually refer to refers to the discharge capacity.
