On October 28th, Cui Dongshu, secretary-general of the National Passenger Car Market Information Joint Council, stated at the 8th my country’s Battery New Energy Industry International Summit Forum that starting from the second half of this year, the new energy vehicle market has begun to show a characteristic of high rise. Drive the high rise of the power lithium battery industry chain, and the industry's prosperity has improved. As the trend of global competition in the new energy automobile industry becomes prominent, the power lithium battery industry chain will be restructured, and domestic companies will break through through continuous technological innovation. Core Value Chain Reconstruction, Ministry of Industry and Information Technology spokesperson and director of the Operation Monitoring and Coordination Bureau, Huang Libin, said that my country's new energy automobile industry has entered a development period from the cultivation period and has become an important force leading the transformation of the global automobile industry. The total domestic investment in the entire industrial chain has exceeded 2 trillion yuan, which has increasingly become a new driving force for development. The new energy market has ranked first in the world in terms of trading volume for 5 years, with a cumulative sales volume of more than 4.8 million vehicles, accounting for more than half of the world’s total. 'With the rise of new powers such as Tesla, and the cross-border entry of technology giants such as the Internet and semiconductors, the auto industry has reshaped the competitive landscape and restructured the core value chain.' Yuan Chengyin, general manager of the National New Energy Vehicle Innovation and Technology Center Said: 'The core value of the future automotive industry will no longer be the engine, body, chassis, but batteries, chips, on-board systems, and data.' Under the general trend of global competition, the power lithium battery industry has further increased its development efforts and the market Fully open to competition, and breakthrough through continuous technological innovation has become the common choice of most domestic companies. In terms of technology research and development, Yuan Chengyin believes that high-capacity ternary materials and artificial graphite are the current mainstream positive and negative materials for high-energy-density batteries. Silicon-carbon materials, low-cobalt or cobalt-free cathode materials continue to develop, and high-nickel materials are still an important direction. The market for lithium iron phosphate in the low-cost field may continue to expand, and solid-state batteries may become an important development direction. 'Solid-state batteries designed based on solid electrolytes are currently a hot spot in the development of secondary batteries, and are an effective way to solve the safety energy density of lithium (sodium) secondary batteries.' said Wen Zhaoyin, director of the Energy Materials Research Center, Shanghai Institute of Ceramics, Chinese Academy of Sciences , By effectively modifying the electrolyte and interface, solid-state lithium batteries and solid-electrolyte sodium chloride batteries already have the basis for quantitative manufacturing. Attaching importance to technological breakthroughs Industry insiders said that this year is an important year for the transformation and upgrading of the global automotive industry and accelerating changes. The integration of electrification, intelligence, and sharing has become the theme of today's development of new energy vehicles and power lithium batteries. Driven by favorable factors such as policies and markets, the power lithium battery industry has ushered in a period of development opportunities. Power lithium battery companies should pay attention to technological breakthroughs and disruptive technological innovations to better participate in international competition. Since 2020, 'cobalt-free' batteries have become a key word in the power lithium battery industry, and industry leaders such as Tesla, BYD, and CATL have entered. Pan Hua, deputy general manager of GEM Co., Ltd., said that the cost of the cobalt-free layered cathode material is relatively low, and it shows certain advantages in price-sensitive fields. It is expected to have better application prospects in the fields of electric two-wheeled vehicles and energy storage. However, the first discharge capacity, cycle performance and rate performance of the cobalt-free layered cathode materials need to be improved. There is still a long way to go to replace NCM or NCA cathode materials, and technical efforts are required. The 'cobalt-free' power lithium battery is mainly based on cost considerations. Gao Fei, general manager of the Honeycomb Energy Cell Ru0026D Center, said at the forum that consumers are price-sensitive. If they want to promote the popularization of electric vehicles, cost reduction is the key requirement for the development and popularization of electrification, and the cost reduction of power lithium batteries, raw materials especially important. Gao Fei analyzed that the price of cobalt fluctuated drastically in the past ten years. In 2018, the price of cobalt materials rose to 600,000 yuan/ton, which seriously affected the healthy development of the entire industry. Therefore, develop cobalt-free or cobalt-less technology, or reserve cobalt prices ahead , Is an important guarantee to promote the continuous cost reduction of batteries. Qian Yitai, an academician of the Chinese Academy of Sciences, pays more attention to high-safety water-based secondary batteries. He believes that lithium batteries have made significant progress in power lithium batteries, but organic electrolytes have hidden safety hazards, and the application of electric bicycles and energy storage still needs further research. Water-based ion batteries are highly safe, and water-based metal oxide batteries can further increase energy density. Water-based zinc-ion batteries are beneficial to inhibit the growth of dendrites and are expected to gradually replace lead-acid batteries. Regarding the development of hydrogen energy and fuel-powered lithium-ion battery technology in China, Chai Maorong, chief expert of hydrogen energy of the State Power Investment Group, suggested that firstly, there must be a technical research organization at the national level to break through the complete localization of key technologies and core materials; secondly, benchmarking internationally The most advanced fuel-powered lithium-ion battery technology, rather than relying on technology introduction to seek subsidies; third, the core of fuel-powered lithium-ion battery is material technology, with a long industrial chain, strategic planning, and division of labor.
