Lithium-ion battery application field, status quo and prospects Lithium battery materials have always been the first choice for green and environmentally friendly batteries. The production technology of lithium batteries has been continuously improved and the cost has been continuously compressed. Therefore, in recent years, lithium batteries have been widely used. According to different application scenarios, lithium-ion batteries are divided into power type, consumer type and energy storage type. Today, the editor will introduce the application of lithium-ion batteries. According to the application scenarios, they can be divided into three types: power, consumption, and storage.

How does the battery work?

Lithium battery is a kind of secondary battery (rechargeable battery) whose work mainly relies on the movement of lithium ions between the positive electrode and the negative electrode. During charging and discharging, Li+ is intercalated or deintercalated back and forth between the two electrodes: during charging, Li+ is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, Li+ is deintercalated.

Lithium-ion battery application field

In recent years, the application of lithium-ion batteries has become more and more extensive. They are mainly used in energy storage systems such as water power, thermal power, wind power and solar power, as well as electric tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, and aviation. Aerospace, etc. Today’s lithium batteries have gradually developed into electric bicycles and electric vehicles.

First, the application of electric vehicles.

At present, most domestic electric vehicles are still powered by lead-acid batteries. Then, the battery itself has a mass of 12 kg. Using lithium-ion batteries, the weight of the battery is only about 3 kg. Therefore, the replacement of lead-acid batteries by lithium-ion batteries has become an inevitable trend in the development of electric vehicles, making electric vehicles portable, convenient, safe, and cheap, and will surely be favored by more and more people.

Second, the application of electric vehicles.

As far as our country is concerned, automobile pollution is becoming more and more serious, and the damage to the environment such as exhaust gas and noise is also becoming more and more serious, especially in some large and medium-sized cities with dense population and traffic congestion. This situation cannot be ignored. Therefore, the new generation of lithium-ion batteries has been vigorously developed in the electric vehicle industry due to its pollution-free, low-pollution, and energy-diversified characteristics. Therefore, the application of lithium-ion batteries is another good strategy to solve current problems.

Third, aerospace applications.

Because of the powerful advantages of lithium-ion batteries, the aerospace agency has also applied it to space missions. The current main role of lithium-ion batteries in the aviation field is to correct launch and flight, and to provide support for ground operations; at the same time, it is beneficial to improve the efficiency of the primary battery and support night operations.

Fourth, other application areas.

From electronic watches, CD players, mobile phones, MP3, MP4, cameras, camcorders, various remote controls, shaving knives, pistol drills, children’s toys, etc. From hospitals, hotels, supermarkets, telephone booths to emergency power supplies for various occasions, power tools widely use lithium-ion batteries.

Li-ion battery upstream and downstream related enterprises.

In the upstream of the lithium-ion battery industry chain, there are mainly various battery materials, such as cathode materials, anode materials, separators, electrolytes, auxiliary materials, structural parts, etc., while in the downstream, they are mainly various battery manufacturers, such as digital products. , Power tools, light power vehicles, new energy vehicles, etc., mainly battery manufacturers.
