Cathode materials for cr2032 button battery
1. Lithium cobalt oxide battery.
Battery cathode material is the earliest battery cathode material used, and it is also a battery cathode material that is still popular in consumer electronic devices at this stage. Compared with other battery cathode materials, lithium cobalt oxide batteries have higher operating voltages, more stable voltage operation during charging or charging and discharging, can meet the requirements of large currents, have strong circulation characteristics, and have high conductivity. The efficiency is high, and the production and processing of raw materials and rechargeable batteries are relatively stable.
But it also has many shortcomings, such as fewer resources, more expensive prices, toxic cobalt, certain risks during use, and adverse effects on the environment. In particular, its safety cannot be further guaranteed, which has become an important factor restricting its general development.
Among them, the research on cation inclusion of metals such as Al3+, Mg2+, Ni2+ is more common. With the gradual advancement of academic construction, more and more countries are currently using ion inclusion methods of metals such as Al3+, Mg2+ and so on. Just started delivery.
There are two main ways to prepare lithium cobalt oxide batteries: solid phase synthesis method and high-efficiency liquid phase synthesis method. It is generally produced using a high-temperature solid phase compounding method, mainly using lithium salts, such as Li2CO3 or LiOH, etc., and cobalt salts, such as CoCO3, etc., mixed in a ratio of 1:1, and at high temperatures of 600°C to 900°C. Made by forging. The current application of lithium cobalt oxide battery materials in the market is mainly concentrated in the secondary battery market, and it is also the first choice for small and medium-sized high-density lithium battery materials.
2. Ternary cathode materials
Compared with traditional lithium cobalt oxide batteries, the ternary synergy is more obvious, has greater advantages in heat resistance, and has lower product cost, making it the best alternative material for lithium cobalt oxide batteries. However, its relative density is low and its circulation system characteristics still need to be improved. Therefore, countermeasures such as improving the generation processing technology and adjusting positive ion inclusions can be adopted.
Nernary materials are mainly used in cylindrical lithium batteries, such as aluminum shells and aluminum shells. However, in soft-pack batteries, their use is greatly restricted due to the impact of expansion factors. Future applications will mainly start from two aspects: one is to develop in the direction of permanganate index, which is mainly used in small and medium-sized portable equipment such as Bluetooth and mobile phones; the other is to develop in the direction of high nickel, which is mainly used in electric vehicles. Vehicles, battery vehicles and other industries with higher energy requirements.
3. Lithium iron phosphate
It has very good charging cycle characteristics and heat resistance, and has a strong safety factor during use. Moreover, this kind of material is low-carbon and environmentally friendly, will not cause serious damage to the environment, and is also relatively cheap. , is regarded as the best raw material for manufacturing large-capacity lithium battery modules in China's battery industry. Current main applications include: pure electric vehicles, portable mobile battery charging power supplies, etc. In the future, there will be further development in the direction of energy storage power supplies, portable power supplies, etc.
4. Lithium manganate battery
Because manganese resources are very abundant in my country, it is relatively cheap, causes little air pollution, is non-toxic and harmless, and is easy to operate in industrial production, so it has strong safety and anti-overcharging properties in use. However, due to the unstable structure of spinel during the charging or charging and discharging process of the battery, and the melting of manganese under high temperature conditions, it is easy to cause a "melting" effect, which greatly limits its use and makes it suffer a lot in actual use. limited.
Today's lithium manganese oxide batteries are mainly used in small and medium-sized rechargeable batteries, such as mobile phones, electronic products, etc. They can replace each other with lithium iron phosphate batteries in terms of power lithium batteries, so they have strong competitiveness and their development prospects will be towards High-efficiency energy, high density, and low cost are the development trends.
