CR927 battery

What are the raw materials for CR927 battery production?

There are many raw materials in the production of CR927 battery packs. The main materials of CR927 battery packs are: positive electrode materials, negative electrode materials, diaphragms, and electrolytes. Lithium-ion batteries are a new generation of green high-energy batteries with excellent performance and have become one of the focuses of high-tech development. At present, the supply of raw materials for CR927 battery packs is sufficient, the output of some products is sufficient, the competition is fierce, and the CR927 battery industry is still hot.

The overall situation of raw materials for CR927 battery production is that there is an oversupply of low-end and medium-end products and a shortage of high-end products. Among them, positive electrode materials, negative electrode materials and electrolytes have gradually become self-sufficient. Due to the relatively low technical barriers of negative electrode materials and electrolytes, the cost advantages of Chinese companies are obviously highly competitive worldwide.

1. Positive electrode materials

Among the positive electrode materials, the most commonly used materials are lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate and ternary materials (polymers of nickel, cobalt and manganese). Positive electrode materials account for a large proportion (the mass ratio of positive and negative electrode materials is 3:1~4:1), because the performance of positive electrode materials directly affects the performance of lithium-ion batteries, and its cost also directly determines the cost of batteries.

CR927 battery pack positive electrode materials have a broad market and a very optimistic prospect. However, there are still certain technical bottlenecks in CR927 battery positive electrode materials, especially its advantages of high capacity and strong safety performance have not been fully utilized. Chinese companies should strengthen the research and development of key technologies for positive electrode materials, achieve international leading position, strengthen core competitiveness, and gain advantages in international competition.

2. Negative electrode materials

Among the negative electrode materials, the current negative electrode materials are mainly natural graphite and artificial graphite. The negative electrode materials being explored include nitrides, PAS, tin-based oxides, tin alloys, nano-negative electrode materials, and some other intermetallic compounds. As one of the four major components of CR927 battery packs, negative electrode materials play an important role in improving battery capacity and cycle performance, and are at the core of the midstream of the CR927 battery industry.

3. Diaphragm

The market-oriented diaphragm materials are mainly polyolefin diaphragms based on polyethylene and polypropylene. In the structure of lithium-ion batteries, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, which directly affects the battery's capacity, cycle and safety performance. The diaphragm with excellent performance plays an important role in improving the comprehensive performance of CR927 battery packs.

4. Electrolyte

The electrolyte of lithium-ion batteries is the carrier of ion transmission in the battery. It is generally made of high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials, under certain conditions and in a certain proportion. The electrolyte plays the role of conducting ions between the positive and negative electrodes of CR927 battery packs, which is the guarantee for lithium-ion batteries to obtain advantages such as high voltage and high specific energy.
