Explain the cathode material of lithium-ion battery in detail

1. Lithium cobaltate battery. The battery cathode material is the first battery cathode material to be used, and it is also a battery cathode material that is still in fashion in consumer electronic equipment at this stage. Compared with other battery cathode materials, the working voltage of lithium cobalt oxide battery is higher when it is working, and the working voltage is more stable when the battery is charged or charged and discharged. It can consider the regulations of large current, and has extremely strong cyclic system characteristics and conductivity High efficiency and relatively stable production and processing of raw materials and rechargeable batteries. But it also has many shortcomings, such as fewer resources, more expensive, cobalt with toxic side-uses, certain risk factors during application and its harmful effects on the natural environment. In particular, its safety factor cannot be further ensured, and it has become a key element that restrains its general development trend. Among them, the scientific research on positive ion inclusion of metal materials such as Al3+, Mg2+, and Ni2+ is more common. With the gradual advancement of discipline construction, more and more my country chooses the method of positive ion inclusion of metal materials such as Al3+ and Mg2+ at this stage. Just started to be delivered. Among them, the key to the preparation of lithium cobalt oxide batteries is the solid-phase formulation method and the high-efficiency liquid phase formation method. Generally, high-temperature solid-phase compounding method is used for production, and the key is to use lithium salt, such as Li2CO3 or LiOH, and cobalt salt, such as CoCO3, in a ratio of 1:1, and under the high temperature standard of 600℃ to 900℃ Calcined. Today, the use of raw materials for lithium cobalt oxide batteries in the sales market is focused on the secondary battery sales market, which is also the preferred choice for small and medium-sized high-density lithium-ion battery raw materials. 2. Compared with the traditional lithium cobalt oxide battery, the ternary cathode material has more obvious synergistic use. It has greater advantages in heat resistance and lower product cost. It can be used as the best lithium cobalt oxide battery. Replace raw materials. However, its relative density is low, and it needs to be improved at the level of circulatory system characteristics. Therefore, countermeasures such as positive ion inclusion can be adjusted according to the improvement of the production process. Ternary materials are mainly used in cylindrical lithium-ion batteries, such as aluminum shells and aluminum shells, but in soft-pack batteries, due to the hazards of swelling elements, their use is greatly restricted. For future applications, the key is to start from two levels: one is the development trend toward the permanganate index value, the key is to use mobile phone Bluetooth, mobile phone and other small and medium-sized portable equipment; the development trend toward the high nickel direction, the key is to use electric Industries with higher energy regulations, such as automobiles and battery cars. 3. Lithium iron phosphate has very good battery charging cycle system characteristics and heat resistance, and has a strong safety factor in the whole process of application, and this kind of raw material is low-carbon and environmentally friendly, and it is not easy to cause serious damage to the natural environment. In addition, the price is more cost-effective, and it is regarded as the best raw material for the production of high-capacity lithium-ion battery control modules in my country's battery industry. Today's key and important uses include: pure electric vehicles, portable mobile battery charging switching power supplies, etc. In the future, energy storage technology switching power supplies and portable switching power supplies will develop in-depth trends. 4. Because the manganese resource is very abundant in our country, lithium manganate batteries are relatively cheap, have little air pollution, are non-toxic and harmless, and are easy to operate in industrial production. Therefore, they have a strong safety factor and anti-overcharge in use. Sex. However, spinel is structurally unstable during the whole process of battery charging or charging and discharging, and the melting of manganese under high temperature standards can easily cause melting effect, which further restricts its application and its specific application.
