A lithium-ion battery is a rechargeable battery that works by moving lithium ions between a positive and negative electrode. Traditionally, the process of lithium ions entering the cathode material is called intercalation, and the process of lithium ions leaving the cathode material is called de-intercalation; the process of lithium ions entering the cathode material is called intercalation, and the process of lithium ions leaving the cathode material is called non-intercalation. Lithium-ion batteries are easily confused with the following two battery concepts:

Lithium-ion battery: Although commonly used as an abbreviation for lithium-ion battery. The lithium-ion battery in the strict sense is a lithium primary battery, and there is a lithium element.

Lithium-ion polymer battery: A lithium-ion battery that uses polymers instead of liquid organic solvents.

Advantage:

1. High energy density: According to different electrode materials, its mass can reach 150~200Wh/kg (540~720kJ/kg). The volume can reach 250~530Wh/L (0.9~1.9kJ/cm3).
2. High open circuit voltage: with the change of electrode material, up to 3.3~4.2v.
3. High output power: up to 300~1500W/kg (@20 seconds), depending on electrode material.
4. No memory effect: The lithium iron phosphate battery has no memory effect, the battery can be charged and discharged at any time without empty charging, and it is easy to use and maintain.
5. Low self-discharge: <5%~10%/month. The monitoring circuitry built into the smart Li-ion battery is even more efficient than the self-discharge current.
6. Wide operating temperature range: -20℃~60℃ work normally.
7. Fast charge and discharge

Therefore, lithium-ion batteries are widely used in consumer electronics, special products, special products, and other fields.

The service life of lithium-ion batteries is about 4 years, which is 1.5 times that of lead-acid batteries. Can be charged and discharged more than 500 times. The battery has no memory and has strong impact resistance.

Lithium-ion batteries have been connected to the Qi meridian and the eight meridians since they were young. They can be charged continuously for 48 hours at room temperature without battery swelling, leakage, breakage, and other accidents, and the capacity remains above 95%. And under the special charger, it can be quickly charged and discharged.
