SMM News: electric vehicles are new strategic products to solve energy and environmental problems. With the continuous improvement of national performance standards for new energy vehicles and the continuous decline of policy subsidies, The battery products with ternary, lithium iron phosphate and lithium manganate as the mainstream have been difficult to balance the cost and range requirements. Therefore, the research and development of a new generation of power lithium battery is the inevitable trend of lithium battery material and technology development in the future.
In March this year, the Ministry of Finance, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the National Development and Reform Commission jointly issued the Circular on further improving the Financial subsidy Policy for the Popularization and Application of New Energy vehicles, which made new regulations on subsidies for new energy vehicles this year. It became the biggest decline in subsidies for new energy vehicles, with subsidies nearly halved.
Industry insiders believe that the big retreat of the state subsidy policy has undoubtedly sounded a wake-up call for everyone-it is time to enter the "weaning" countdown. In the post-subsidy era, higher requirements have been put forward for the cost reduction, efficiency and quality management of power lithium battery enterprises. The major reshuffle of the industry has brought great challenges to many enterprises. However, under the big reshuffle and big challenges, there are often great opportunities. For companies that are prepared and powerful, or opportunities outweigh challenges.
At present, the cathode materials of electric vehicle batteries are mainly ternary and lithium iron phosphate. However, with the sharp rise in the price of cobalt and nickel raw materials in the upper reaches in recent years, the cost of ternary material battery is also increasing, and the battery cost accounts for about 40% of the whole vehicle cost. The technology and cost of automobile power battery restrict the rapid development of new energy vehicles.
It is understood that Zhejiang Aoyou Power recently large-scale production of a lithium-rich manganese dioxide battery or is expected to become a strong substitute for lithium iron phosphate battery and ternary battery. Zhejiang Mingyou Power is a professional R & D and manufacturing enterprise of Zhejiang Zhixin holding Group, which has established R & D and production bases in Huzhou, Zhejiang Province and Zhaoqing, Guangdong Province. The lithium-rich manganese dioxide battery with independent intellectual property rights has broken through the key technologies and is the first to achieve mass production in the industry, which provides a solution for continuously improving energy density and safety and effectively reducing costs.
"the content of cobalt and nickel in lithium-rich manganese is only about 1 / 3 of that of ternary materials, and it can even be free of cobalt, and the maximum capacity is up to 300mA / g, which is much higher than that of ternary and lithium manganate. At the same energy density, the cost of lithium-rich manganese dioxide batteries is 20% to 30% lower than that of ternary batteries. At the same time, the mass energy density of lithium-rich manganese dioxide battery is more than 20% higher than that of lithium iron phosphate. " Dr. Wang Changyin, an expert from the Institute of Power Research, said that lithium-rich manganese dioxide power batteries combine the advantages of lithium manganate, ternary, and lithium iron phosphate, and have the advantages of low cost, high energy density, long life, high safety, and so on. It is expected to become the mainstream material of power battery in the future and provide strong power for the popularization and development of new energy vehicles.
The mass production of lithium-rich manganese dioxide power battery has always been considered a difficult problem in the industry. The difficulties in its application are low efficiency, poor conductivity and difficult matching of high voltage electrolyte. After 8 years of painstaking research and overcoming difficulties, the electrochemical performance of lithium-rich manganese dioxide power battery has made a breakthrough and reached the level of industrial application.
Zhao Fusheng, assistant president of Mingyou Power, said that if you want to survive and continue to develop healthily after the big waves, the only "shortcut" is to get rid of impetuous mentality, honestly pay close attention to fine management, and keep your feet on the ground to practice your internal skills. A technical problem, a problem solving, seriously do a good job in every product, only in this way, it is possible to laugh to the end.
