From November 27th to 28th, the 7th Lithium - Battery Technology and Industry Development Conference was successfully held at the Chengdu Science Fiction Museum.

Nan Cewen, an academician of the Chinese Academy of Sciences, an academician of the World Academy of Sciences, and a professor at Tsinghua University; Sun Xueliang, a foreign academician of the Chinese Academy of Engineering, an academician of the Canadian Academy of Engineering, an academician of the Royal Society of Canada, and the dean of the Institute of Materials and Energy at Ningbo Institute of Technology; Liu Jing, a member of the Party Leadership Group and secretary of the Party Committee of the Chengdu Investment Promotion Bureau; Zhao Jidong, the deputy secretary of the Pixian District Party Committee and the head of the district government; Zhou Chaoyi, a member of the Standing Committee of the Pixian District Party Committee and the head of the Publicity Department; Ran Jieying, the deputy head of the Pixian District Government; Xia Yong, a member of the Party Leadership Group of the Pixian District Government and the executive deputy director of the Management Committee of the Chengdu Innovation and Entrepreneurship Demonstration Base; Feng Yuchuan, the chairman, and Li Zheng, the general manager of Qingtao (Kunshan) Energy Development Group Co., Ltd. attended this event.

At present, the global new - energy industry is developing vigorously. The "new three major exports" of China's foreign trade, namely new - energy vehicles, lithium - ion batteries, and photovoltaic products, are popular around the world. Lithium - battery technology is constantly innovating and making breakthroughs, boasting broad market prospects and huge development potential. In particular, solid - state batteries, a typical representative of new - quality productive forces, have become a "magic weapon" for powerful countries in the second - half competition of the new - energy vehicle market and are especially favored by the capital market. The organizer, Qingtao Energy, a global leader in the industrialization of solid - state batteries and a global unicorn enterprise, in collaboration with SAIC Motor, took the lead in launching a real - world vehicle with a pure - electric range of over 1000 kilometers and the industry's first quasi - 900V ultra - fast - charging solid - state battery. The semi - solid - state battery has been mass - produced and installed in vehicles, and the mass production of the all - solid - state battery is approaching. The industrial innovation consortium has been reporting successive good news.

Under the guidance of the national "dual - carbon" strategic goals, Chengdu has designated new energy and new materials as key industrial chains for building industrial clusters and strengthening the industry chain. It has become a national high - tech industry base for the new - energy industry and an important part of China's battery - industry landscape. During their speeches, Academician Nan Cewen, the conference chairman, and Feng Yuchuan, the chairman of Qingtao Energy, highly commended Chengdu's advantages in developing the new - energy industry, such as its solid industrial foundation, strong technological strength, abundant natural resources, and large consumer market. They believed that the city has a favorable atmosphere for supporting and encouraging innovation, preferential policies for attracting and cultivating talents, and a highly considerate and comfortable business environment. This will attract more and more enterprises like Chengdu Qingtao New Energy Technology Co., Ltd. to settle in Chengdu and increase investment, injecting new impetus and vitality into Chengdu's high - quality development and providing strong support for the basic establishment of a park - city demonstration area that practices the new development concept.

All - solid - state lithium - ion batteries have drawn extensive attention due to the high ionic conductivity of the solid electrolyte, the inherent safety of the battery, and its higher energy density. Academician Sun Xueliang delivered a conference report titled "Halide - based All - solid - state Batteries: From the Development of Solid Electrolytes to Interface Design". Academician Sun believes that the solid electrolyte is a crucial component in all - solid - state batteries, and there are still significant challenges in addressing the interface problem between the electrolyte and the electrode. He expounded on the importance of interface design and regulation in an accessible yet profound manner.

Dr. Li Zheng, the general manager of Qingtao Energy, delivered a report titled "The Industrialization Path and Practice of Polymer - Composite All - solid - state Lithium - ion Batteries". He believes that the key to realizing the industrialization of all - solid - state batteries lies in material innovation, interface matching, the development of manufacturing processes, the development of mass - production equipment, and the development of all - solid - state battery system integration. Finally, through vehicle - level verification, the industrialization of all - solid - state power batteries can be achieved. The report focused on the selection of the solid - state electrolyte system and process path, the progress of the development of solid - state dedicated cathode materials, and the industrialization path and progress of all - solid - state batteries.

Li Feng, the founding partner of FreeS Fund; Yang Yong, a professor at Xiamen University; Wang Fang, a senior chief expert of China Automotive Technology and Research Center Co., Ltd. and the chief engineer of the New - Energy Vehicle Testing Center; Wang Jiantao, the deputy general manager of Guolian Automotive Power Battery Research Institute Co., Ltd., and other experts, scholars, entrepreneurs, and investors delivered wonderful reports. These reports covered not only specific issues within the lithium - battery industry but also extended to major issues such as new energy, new materials, resource utilization, and value investment, winning wide acclaim from the participants.

Before the opening ceremony, the conference held the groundbreaking ceremony for the Qingtao Solid - state Battery Southwest Industrial Base project. The project is planned to have a total investment of 10 billion yuan and an annual production capacity of 15GWh. It will establish a national demonstration ecological circle for the new - energy energy - storage industry and build an international high - ground for new - energy technology research and development.

Chengdu Qingtao signed a strategic - cooperation agreement with Chengdian Construction and the Second Company of China Construction Eighth Engineering Division. They will integrate their advantageous resources and carry out practical and efficient strategic cooperation in aspects such as industrial - park construction, industrial investment promotion, industrial - ecosystem cultivation, and the market development of solid - state batteries, achieving collaborative innovation.
