What is the mainstream negative electrode material for power batteries?

It is reported that the lithium battery is mainly composed of a positive electrode material, a negative electrode material, a separator, an electrolyte, etc., and the negative electrode material accounts for about 10% of the cost of the lithium battery material. Graphite is an anode material used earlier. Compared with other carbon materials, its conductivity and crystallinity are higher. The good layer structure and charge-discharge voltage are also very suitable for the decoupling movement of the cathode material, and the current process is mature. The lower cost is an ideal anode material.

Artificial graphite is a graphite product produced by high-temperature treatment of easily graphitizable carbon. With the development of power batteries and high-end consumer batteries, the market demand for battery performance continues to increase, and artificial graphite has gradually become the mainstream anode material due to its excellent performance. According to the data, the proportion of artificial graphite production has continued to increase from 39.7% in 2013 to 68.9% in 2016, and is expected to continue to grow.

Under the continuous demand of new energy vehicles, by 2020, the demand for power batteries will be about 94GWh, the demand for anode materials will be about 70,000 tons, and the market for anode materials for power batteries will be about 4 billion yuan. By 2025, the demand for power batteries will be The amount will reach 310GWh, the corresponding anode material demand will reach 190,000 tons, and the power battery anode material market will reach 10 billion yuan.
