Single crystal high-nickel cathode materials are mainly used in the field of lithium-ion batteries. my country’s research has made new progress

Single crystal high-nickel cathode materials refer to lithium-ion battery cathode materials composed of nickel, manganese, cobalt and other metal elements, in which the nickel content reaches more than 60%. Compared with polycrystalline high-nickel cathode materials, single-crystal high-nickel cathode materials have the characteristics of long cycle life, good electrical performance, high energy density, and good structural stability, and are widely used in the fields of consumer electronics and new energy vehicles.

The main preparation methods of single crystal high nickel cathode materials include co-solvent method, co-precipitation method, sol-gel method, etc. The co-solvent method refers to the use of LiCl-NaCl co-solvent to prepare finished products. This method can prepare high-quality single crystal high-nickel cathode materials, but it has the disadvantages of easily causing equipment corrosion and high production costs; the co-precipitation method is also called co-precipitation-high temperature Solid-phase method. The single-crystal high-nickel cathode material produced by this method has the advantages of good mechanical properties, controllable particle size, and good uniformity, and is suitable for large-scale production.

Single crystal high-nickel cathode materials have excellent performance. In recent years, local companies and scientific research institutions have continued to increase investment in research and development, driving the prosperity of my country’s single crystal high-nickel cathode materials industry to continue to increase. In December 2022, the research team of Guo Yuguo of the Institute of Chemistry, Chinese Academy of Sciences, together with researcher Yu Xiqian of the Institute of Physics, the team of Professor Wang Chunsheng of the University of Maryland, and Dr. Li Yangxing of Chery New Energy, successfully prepared single crystal high-voltage nanoparticles with controllable particle sizes in the range of 1-12 μm. Nickel cathode material, which has both high quality energy density and high volume energy density.

According to the “2023-2028 China Single Crystal High Nickel Cathode Materials Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that single crystal high-nickel cathode materials are mainly used in the field of lithium-ion batteries, and consumer electronics, new energy vehicles, etc. are their end products. With the support of national policies and the growth of market demand, the development speed of my country’s lithium-ion battery industry has accelerated. According to statistics from the Ministry of Industry and Information Technology, my country’s lithium-ion battery production will reach 750GWh in 2022, an increase of 131.5% over the previous year. Benefiting from the rapid growth of lithium-ion battery production, the market demand for single crystal high-nickel cathode materials is increasingly strong.

my country’s monocrystalline high-nickel cathode material industry is highly concentrated. Major market participants include Guizhou Zhenhua New Materials Co., Ltd., Ningbo Rongbai New Energy Technology Co., Ltd., Zhejiang Pawa New Energy Co., Ltd., and Shandong Fengyuan Chemical Co., Ltd., etc. Rongbai Technology is my country’s leading company in single crystal high-nickel cathode materials. Currently, the company has conquered a number of key technologies. High-nickel NCM811 is its star product, and its shipments have maintained a long-term growth trend.

Industry analysts said that with the growth of lithium-ion battery market demand, the development speed of the single crystal high-nickel cathode material industry will further accelerate. Compared with polycrystalline high-nickel cathode materials, my country’s single-crystal high-nickel cathode materials market share is lower. In the future, as the technological innovation level of local enterprises continues to improve, my country’s single-crystal high-nickel cathode material market space will be further expanded.
