Lithium ion battery is a kind of rechargeable battery, which mainly depends on the movement of lithium ion between the positive and negative electrodes. Traditionally, the process of lithium ion entering the positive material is called embedding, and the process of leaving is called deblocking; the process of lithium ion entering the negative material is called inserting, and the process of leaving is called deblocking. Lithium ion batteries are easily confused with the following two battery concepts:

Lithium battery: although it is often used as the abbreviation of lithium-ion battery. But strictly speaking, the lithium battery is the original lithium battery, and there is lithium element.

Lithium-ion polymer battery: a kind of lithium-ion battery using polymer instead of liquid organic solvent, with good safety.

Advantage

High energy density: depending on the electrode materials, it can reach 150-200wh / kg (540-720kj / kg) by mass, and 250-530wh / L (0.9-1.9kj / cm3) by volume.

High open circuit voltage: different electrode materials, up to 3.3-4.2v.

High output power: different electrode materials, up to 300-1500w / kg (@ 20s).

No memory effect: lithium iron phosphate lithium ion battery has no memory effect. The battery can be charged and discharged at any time without discharging electricity, so it is easy to use and maintain.

Low self discharge: < 5% ~ 10% / month. Because of the built-in monitoring circuit, the working current of the intelligent lithium-ion battery is even higher than the self discharge current.

Wide working temperature range: it can work normally between - 20 ℃ and 60 ℃.

Fast charging and discharging

Therefore, lithium-ion batteries are widely used in consumer electronics, military products, aviation products and so on.

Health preservation and durability (life improvement) lithium battery is the best way to survive. The average life of lithium battery is about 4 years, about 1.5 times longer than that of lead-acid battery. It has been charged and discharged more than 500 times. The battery has no memory and strong seismic resistance.

Since childhood, the lithium battery has opened eight channels of channels, so that under normal temperature, the lithium battery can be continuously charged for 48 hours without accidents such as battery expansion, leakage and fracture, and the capacity is kept above 95%. And under the special charger, it can charge and discharge quickly.
