The agency expects China's shipments of anode materials to increase from 365,000 tons in 2020 to 1.48 million tons in 2025, with a compound annual growth rate of 32%. Enterprises with higher graphitization self-supply rate and gradually improved integrated industrial layout have strong cost advantages and are expected to realize both volume and profit.
New breakthroughs have been made in Lithium Battery materials
Charging is expected to speed up
According to the proceedings, recently, member of China university of science and technology shu-hong yu team with professor Yao Hongbin, NiYong team, committed to solve high energy density Lithium ion Batteries and the contradiction between the fast charging performance, put forward and the preparation of a new type of double gradient graphite anode materials, realization of lithium ion battery charging 60% in 6 minutes. The results were recently published in Science Advances.
At present, electric vehicles driven by Lithium Ion Batteries are favored by people for their energy saving and environmental protection. However, the charging time of electric vehicles is much longer than the refueling time of traditional fuel vehicles, which greatly reduces the user experience. The main reason is the poor rate performance of graphite anode in Lithium Ion Battery, which limits the fast charging ability of electric vehicles.
In order to improve the rate performance of graphite anode, the conventional strategy is to make the graphite electrode porous or thin. However, these methods tend to sacrifice the energy density of the resulting cell. Yu shuhong's team started from designing the electrode structure to improve the fast charging performance of lithium-ion batteries under the condition of ensuring the energy density.
The research team developed a self-assembly technology of low viscosity non-polymer binder paste. The paste was prepared by mixing copper-coated graphite anode particles and copper nanowires in ethanol solution. By using the difference of settling velocity of graphite particles of different sizes in the paste, the simulated calculation optimization of double gradient structure was successfully constructed to obtain the electrode.
The researchers found that lithium-ion batteries based on the new dual-gradient graphite anode material charged from zero to 60% and 80% in 5.6 and 11.4 minutes, respectively, while maintaining high energy density.
The explosive growth of Cathode materials in China
Graphitization supply and demand is tight
Since the fourth quarter of 2020, the cathode material market ushered in explosive growth. According to the "White Paper on The Development of China's Cathode Material Industry (2022)" jointly released by research institute EVTank and IVEY Economic Research Institute, shipments of cathode materials in China reached 779,000 tons in 2021, up 86.4 percent year-on-year. The global share increased from 77.7% in 2020 to 86.1% in 2021.
According to Dongguan Securities Research Report, China is the world's most important producer of anode materials, with its shipments increasing to about 70% in the past two years. China's shipments of anode materials are expected to increase from 365,000 tons in 2020 to 1.48 million tons in 2025, with a compound annual growth rate of 32%.
Under the influence of national dual control of energy consumption, the production capacity of graphitization processing with high energy consumption is limited. Meanwhile, the demand of downstream new energy vehicle market is growing rapidly, and the supply and demand of graphitization is tight. In recent years, China's lithium battery anode material head enterprises have gradually moved to the upstream graphitization processing layout. The enterprises with higher graphitization self-supply rate and gradually improved integrated industrial layout have strong cost advantages and are expected to realize the simultaneous rise of volume and profit.
