As the new energy automobile industry enters a new stage of development, the technological innovation of power lithium batteries is also opening a new chapter, and the next generation of power lithium battery technology has high hopes. On April 15, the 2021 Second Next Generation Battery Technology and Market Application Seminar hosted by Shandong Zaozhuang National High-tech Industrial Development Zone and Battery Network was held in Zaozhuang, Shandong. Representatives and experts from various companies in the new energy automobile industry chain More than a hundred guests, including scholars and media representatives, gathered in Zaozhuang High-tech Zone, Shandong, to discuss the current status of the power lithium battery industry and the development of next-generation battery technology. In-depth discussions and exchanges were conducted on topics such as battery commercial use and next-generation battery technology with the most investment value. Lithium-ion battery technology urgently needs to be upgraded. With the development of new energy vehicles along the way, in the past few decades, the important power lithium battery technology of new energy vehicles has matured. The practicability of products has been greatly improved, and market applications have accelerated, but still There are many development bottlenecks, and its energy density is gradually approaching the theoretical 'ceiling'. In this context, based on the innovation of the existing lithium-ion battery technology system, the leading companies in the industry chain are aiming at the post-lithium-ion battery era, opening up the layout of next-generation batteries in advance to enhance core technological competitiveness. According to Qilu, a professor at Peking University, the upgrading of my country's lithium-ion battery industry must solve the technical problems of existing lithium-ion batteries, the transition period of all-solid-state lithium-ion batteries, and so on. However, many of these technical problems are difficult to overcome at present. Professor Wang Haiyan of Central South University further stated: “Battery performance, cycle life, cost, specific power, specific energy and safety are important factors in evaluating the application potential of lithium-ion battery cathode materials. High nickel ternary materials have significant advantages and are currently designed to be high The preferred cathode material for specific energy lithium-ion batteries, and the production and market share of high-nickel ternary cathode materials are also increasing. It is the most promising high-energy density cathode material for lithium-ion batteries in the next few years.' Commercialization of fuel power batteries Not overnight. With the development of the new energy automobile industry, the innovation of power lithium batteries in materials and structures is also constantly advancing. At present, from the national level to local governments at all levels, my country’s support for the hydrogen energy and fuel power battery industries has been continuously strengthened. The era of demonstration and application of hydrogen fuel battery vehicles has begun. The enthusiasm of various companies for fuel power batteries is unabated. The commercialization of batteries is accelerating. Yuan Chengyin, general manager of the National New Energy Vehicle Innovation and Technology Center, introduced that with the guidance of national policies and the development of fuel power cell technology, my country has gradually formed the Beijing-Tianjin-Hebei, East China, South China, and other cities with car companies as the carrier. In this industry cluster, it is expected that the real large-scale volume of fuel-powered vehicles will be increased after 2030, and fuel-powered batteries will be applied in more fields in the future. 'In my country, the fuel power cell industry has just entered the market introduction stage. Fuel power cell stacks and systems initially meet the needs of commercial vehicles, and some of their performance catches up with the international level, but in terms of engineering design and verification capabilities, and key component manufacturing levels, etc. There are still some obvious gaps. At the same time, the industrial chain is not perfect, the material gap is large, the relevant standards, regulations, and testing methods are still lagging, which also restrict the development of my country's hydrogen energy industry.' Executive Dean of Guangdong Provincial Wuhan University of Technology Hydrogen Energy Industry Technology Research Institute Zhang Ruiming further pointed out that, in his opinion, the road to large-scale hydrogen energy application should be supported by core technology, and it requires substantial cooperation and positive development of industries and companies. Solid-state batteries have a long way to go. The power lithium battery industry has never stopped the pace of technological innovation. In the current research direction of next-generation batteries, in addition to the current mainstream liquid lithium-ion battery upgrade and the industrialization of fuel power batteries, enter In 2021, with NIO's launch of semi-solid battery products on NIODay as the node, the 'wings' of solid-state batteries are also fanning a big storm. Under the 'wind'Solid-state batteries are one of the solutions to the problem of improving battery safety, and it can also improve convenience through high battery life. In the future, once the economic problem is solved, the era of solid-state batteries may accelerate.' At the meeting, Tianfeng Securities Yang Chengxiao, deputy director of the Research Institute of the Co., Ltd., said that in his view, to solve the technical problems of mass production of electrolytes, the mass production cost of solid-state batteries may be comparable to that of liquid batteries. Xiang Jin, deputy general manager of Beijing Weilan New Energy Technology Co., Ltd. predicts that hybrid solid-liquid batteries can take into account the performance advantages of liquid batteries and all-solid-state batteries, and can be compatible with existing processes, equipment and materials to the greatest extent. Mass production, however, all-solid-state battery technology still faces many technical challenges, including the development and engineering of high-performance battery materials. All-solid-state batteries are expected to be commercialized within 5-10 years.
