Lithium ion electricity mainly depends on the movement of lithium ions between the positive and negative electrodes. During charging and discharging, Li + is intercalated and de intercalated back and forth between the two electrodes: during charging, Li + is de intercalated from the positive electrode and embedded into the negative electrode through electrolyte, and the negative electrode is in a lithium rich state; It is the opposite when discharging. So what are the main application fields of lithium-ion batteries? The following is a brief introduction by the technicians of Dianming technology, which can be divided into seven categories of applications in different industries:
1. Mobile phone applications:
With the development of mobile phones to light, thin, short and miniaturized, the need for small and high-capacity batteries will be increased accordingly, which can save a lot of space. To minimize the size of mobile phones, only lithium-ion batteries are the best power supply.
2. Application of electric bicycle:
With the development of economy, electric bicycle has become one of the ideal choices at present. Because electric bicycles will not produce environmental pollution when they are running, and it is an inevitable trend for lithium-ion batteries to replace the lead-acid batteries of electric bicycles. In this way, the lightness, convenience, safety and cheapness of electric bicycles will be welcomed by more and more people.
3. Application of electric vehicles:
For China, automobile pollution is becoming more and more serious, and the damage of exhaust and noise to the environment must be controlled and treated, especially in some large and medium-sized cities with dense population and traffic congestion. Therefore, it will be an inevitable trend to develop a new generation of electric vehicles and hybrid electric vehicles as new vehicles with no pollution, less pollution and diversified energy allocation.
4. Aerospace Applications:
Due to the strong advantages of lithium-ion battery, it has been used in Mars lander and Mars rover. Lithium ion batteries will also be used in the future series of exploration missions (2005-2007). In addition to NASA's interstellar exploration, other space organizations are also considering the application of lithium-ion batteries in space missions. At present, the main role of lithium-ion battery in aviation field is to provide support for launch, in-flight correction and ground operation; At the same time, it is conducive to improve the efficiency of primary battery and support night operation.
5. Military applications:
For the military, lithium-ion batteries are not only used for military communications, but also for sophisticated weapons, such as torpedoes, submarines, missiles, etc; Because lithium-ion battery has very good performance, high energy density and light weight, it can promote the flexibility of weapons.
6. Other applications:
From electronic watch, CD player, mobile phone, MP3, MP4, camera, camera, various remote controls, shaving knife, pistol drill, children's toys, etc. From hospitals, hotels, supermarkets, telephone exchanges and other occasions of emergency power supply, electric tools.
The above is the main application fields of lithium-ion battery introduced by the technicians of Dianming technology. Lithium-ion battery is known as the "battery of the 21st century", which will open up a new era of battery and has a very optimistic development prospect
