Six major materials of lithium batteries
1. Lithium titanate: In recent years, China has shown strong enthusiasm for lithium titanate products. Lithium titanate has a long cycle life, is a zero-strain raw material, and cannot be converted into the traditional tin film definition. Disadvantages: The key factor limiting the use of lithium titanate at this stage is the high price, which is higher than traditional high-purity graphite, while lithium titanate is smaller, down to 170mah/g. Only by improving the production process, reducing manufacturing costs, increasing the long-term service life of the lithium titanate system, and fast charging can the advantages be fully utilized. Lithium titanate combines sales market and technology and is more suitable for the space bus and energy storage technology industries.
2. Graphene material: Since 2010, the advantages of graphene material have won the Nobel Prize in China and are widely loved by countries around the world. Graphene materials have excellent properties such as good transmittance, excellent electrical conductivity, high heat transfer, and high impact toughness. They are the trend in the research and development of graphene materials. As a positive and reverse phase preservative, it can improve the reliability of lithium-ion batteries, improve the service life of the circulation system, and increase the internal conductivity. Disadvantages: Due to the immaturity, high cost, and unstable performance of large-scale production and processing of graphene materials, graphene materials will be used as positive and negative preservatives in lithium-ion packaging.
3. Silicon-carbon composite anode material: Advantages: As a future battery cathode material, the basic theoretical volume of silicon-carbon polymer material is about 4200mah/g or more, and the high-purity graphite grade is more than 10 times more than 372mah/g. Its industrial development will greatly increase the battery capacity. . Disadvantages: During the entire charging process, the volume increases to 300%, which will cause particles of photovoltaic materials and cause volume damage to the raw materials. In addition, the suction power is poor. The service life of the circulation system is very poor. At this stage, this problem has been solved based on silicon nanotechnology, silicon carbon packaging, packaging and other methods, and some companies have made some progress.
4. Lithium-rich manganese-based cathode materials: High capacity is one of the development prospects of lithium-ion batteries, but the specific energy of lithium-phosphorus batteries in cathode materials is 580h/kg, and the specific energy of lithium-cobalt-manganese batteries is 750h/kg. The basic theory of lithium-rich manganese can reach 900wh/kg, which has become a hot spot in the product development network. The advantage of lithium-rich manganese as a cathode material is that it has higher energy than core materials and is rich in color. The disadvantages are: the first charge and discharge efficiency is very low, the raw materials evolve throughout the oxygen cycle, causing safety risks, the service life cycle system is poor, and the multiple performance is low. But the development potential is huge.
5. Coated separator: The application of separator is particularly important for the safety factor of lithium-ion batteries. It provides the film with excellent electro-photocatalysis and heat resistance, while maintaining high penetration during the continuous charging process of lithium-ion batteries. The application effect of the film is to improve the high-temperature convergence of the film, avoid large-scale short-circuit failures caused by film convergence, reduce the thermal conductivity of the coating material, and prevent some heat in the rechargeable battery from being unable to control the total heat.
6. Carbon nanotubes (CNTs) have high-quality conductive energy. Due to their low depth and short stroke, they can be used as large multi-battery cathode materials to improve the charging characteristics of lithium-ion batteries. With its unique hollow structure, high conductivity and large specific surface as a medium, it improves the electrical properties of other cathode materials. Disadvantages: As a cathode material for lithium-ion batteries, carbon nanotubes have problems such as large size, low operating voltage, and large charging and discharging service platform.
In short, the prospects of new CR2450 battery materials in future industries cannot be underestimated. Although they currently have some shortcomings and deficiencies, they will gradually improve themselves and become a potential new material for CR2450 battery packs.
