The agency predicts that the shipment of negative electrode materials in China will increase from 365000 tons in 2020 to 1.48 million tons in 2025, with a compound annual growth rate of 32%. Enterprises with high self supply rate of graphitization and gradual improvement of integrated industrial layout have strong cost advantages and are expected to achieve both volume and profit.
lithium battery materials have made new breakthroughs
charging is expected to speed up
According to China Science Daily, recently, the team of academician Yu Shuhong of the University of science and technology of China, in cooperation with the teams of Professor Yao Hongbin and Professor Ni Yong, is committed to solving the contradiction between high energy density and fast charging performance of lithium-ion batteries, and proposed and prepared a new double gradient graphite cathode material to realize 60% charging of lithium-ion batteries in 6 minutes. Relevant achievements were recently published in scientific progress.
At present, electric vehicles driven by lithium-ion batteries are favored by people because of their energy conservation and environmental protection. However, the charging time of electric vehicles is much longer than that of traditional fuel vehicles, which greatly reduces the sense of use experience. The main reason is the poor rate performance of graphite negative electrode in lithium-ion battery, which limits the rapid charging capacity of electric vehicles.
In order to improve the rate performance of graphite negative electrode, the traditional strategy is to make the graphite electrode porous or thin. However, these methods often sacrifice the energy density of the prepared battery. Yu Shuhong's team started with designing the electrode structure to improve the fast charging performance of lithium-ion batteries while ensuring the energy density.
The research team developed a self-assembly technology of low viscosity non polymer binder slurry, mixed copper coated graphite negative electrode particles and copper nanowires into slurry in ethanol solution, and successfully constructed a simulated and optimized double gradient structure by using the difference of settlement velocity of graphite particles with different sizes in the slurry.
The researchers found that the lithium-ion battery based on the new double gradient graphite cathode material was charged from zero to 60% and 80% in 5.6 minutes and 11.4 minutes, respectively, while maintaining high energy density.
explosive growth of negative electrode materials in China
graphitization supply and demand is tight
Since the fourth quarter of 2020, the negative electrode material market has witnessed explosive growth. According to the white paper on the development of China's negative electrode material industry (2022) jointly released by evtank and ivy Economic Research Institute, in 2021, China's negative electrode material shipments reached 779000 tons, a year-on-year increase of 86.4%. The global share increased from 77.7% in 2020 to 86.1% in 2021.
Dongguan securities research report said that China is the world's leading producer of cathode materials, and the proportion of shipments has increased to about 70% in the past two years. It is estimated that the shipment of negative electrode materials in China will increase from 365000 tons in 2020 to 1.48 million tons in 2025, with a compound annual growth rate of 32%.
Under the influence of the dual control of national energy consumption, the graphitization processing capacity with high energy consumption is limited. At the same time, the demand of the downstream new energy vehicle market is growing rapidly, and the supply and demand of graphitization is tight. In recent years, China's lithium battery negative electrode material head enterprises have gradually shifted to the upstream graphitization processing layout. Enterprises with high graphitization self supply rate and gradually improved integrated industrial layout have strong cost advantages and are expected to achieve both volume and profit.
