On November 13th, the 6th Lithium Battery Technology and Industry Development Forum was successfully held in Kunshan.

      Nan Cewen, an academician of the CAS Member and a professor of Tsinghua University, delivered a speech via video as the chairman of the forum: under the current background of the national dual carbon strategy, the new energy vehicle and energy storage industry showed a trend of rapid development, the lithium battery technology continued to iterate, and the development of the lithium battery industry was even more prosperous. On the application demand side, people are looking forward to safer, more reliable, higher energy, and lower cost batteries. The purpose of this forum is to create a distinctive platform for close exchange and cooperation between lithium battery technology, industry, academia, research, and capital. It aims to exchange and discuss innovative technologies for batteries, application needs for new energy vehicles and energy storage, as well as entrepreneurial investment opportunities, in order to promote the vigorous development of new generation lithium battery technology and industry.

During his speech, Feng Yuchuan, Chairman of Qingtao Energy, introduced that this year, Qingtao Energy hosted the launch and implementation plan demonstration meeting of the "Key Materials and Applications of High Safety Lithium ion Power and Energy Storage Batteries" project, a national key research and development plan for the 14th Five Year Plan. The national competent department specifically invited Qingtao Energy to report on its work and conduct on-site inspections in the company, which was fully recognized. Qingtao Energy will live up to its heavy trust, continue to deepen its solid-state battery technology, and work together with upstream and downstream partners to promote and link development, creating a new energy vehicle industry cluster with international competitiveness.

——The first generation product developed by Qingtao Energy has introduced solid-state electrolyte materials and developed unique processes and equipment, significantly improving the energy density and safety performance of batteries. It has been successfully applied in new energy vehicles, specialty, energy storage and other fields. In a few months, it will be mass-produced on SAIC Zhiji's vehicle, with a range of over 1000 kilometers.

——Qingtao Energy's second-generation product development is a high-performance solid-state system, matched with high-voltage manganese positive electrodes and high-capacity silicon-based negative electrodes. With innovative dry electrode technology, it can further improve safety and significantly reduce costs. By 2025, it will be equipped in multiple SAIC vehicle models to achieve a sales scale of "100000 vehicles".

——The third-generation products of Qingtao Energy undergo full solid-state technological innovation in battery material system, structural design, and manufacturing process, breaking through energy density limits and achieving "absolute safety" in engineering sense.

      Academician Sun Xueliang gave a keynote speech on the development of new halide solid electrolytes: from materials to interfaces and battery applications, introducing the latest cutting-edge developments and achievements in the development of new halide solid electrolyte materials, as well as interface design and battery applications.

Zhu Jun, Deputy Chief Engineer of Shanghai Automotive Group Co., Ltd., Vice President of Shanghai Automotive Group Innovation Research and Development Institute, and General Manager of Shanghai Jieneng Automotive Technology Co., Ltd., gave a keynote speech on "What kind of batteries are needed in the era of comprehensive electrification?" emphasizing that in the era of comprehensive electrification, we do not pursue the "far ahead" of individual technologies, but rather become a "polygonal warrior" without shortcomings. The safety, reliability, performance, and cost of batteries are evaluated by multiplying the scores of these four items, which is the final result.

Professor Xia Dingguo from Peking University gave a report on the new progress in the research of lithium rich manganese based cathode materials. The report introduced high-capacity lithium rich cathode materials, and studied basic scientific issues such as how to suppress gas production and voltage decay of lithium rich manganese based cathode materials, how to improve the doubling performance of lithium rich cathode materials, and the development of polymer electrolytes based on deep eutectic in-situ solidification based on molecular engineering, which has an important promoting effect on the practical application of lithium rich cathode materials.

Xiao Chengwei, a researcher at the 18th Research Institute of China Electronics Technology Group, focused on the development status and trends of automotive power battery technology. He talked about power batteries as the core key components of new energy vehicles, and their technology and industrialization level have a significant impact on the development and large-scale application of new energy vehicles. The report briefly introduced the development status of China's new energy vehicles and power battery industry, summarized the current development roadmap of power battery technology, summarized the current large-scale supporting power battery technology routes and products, next-generation power battery technology and products, new system batteries (all solid state batteries and sodium ion batteries), intelligent batteries, all climate battery system integration, system safety technology (including big data), and testing and evaluation technology, among other related content. And analyzed its application prospects.

Li Zheng, General Manager of Qingtao Energy, gave a report on "Composite Solid Electrolytes and Solid State Battery Industrialization". The report starts with the important significance of all solid state batteries for the development of the new energy vehicle industry, analyzes the prospects and difficulties of industrialization from various solid electrolyte material technologies, and combines laboratory work to introduce the exploration and industrialization of constructing an organic-inorganic composite solid electrolyte technology route. Through the development path and phased practical achievements of Qingtao Energy in the industrialization process of all solid state batteries, this paper mainly introduces the construction of organic inorganic solid electrolyte system, and proposes the development ideas in the field of positive electrode, negative electrode, and battery cell engineering required to achieve the industrialization of all solid state batteries. At the same time, introduce the mechanism of collaborative innovation between Qingtao Energy and SAIC Group, gradually moving towards the mass production and application of solid-state batteries.
