Global advanced battery forward-looking technology conference held in Yibin, Sichuan

China News Service, Yibin, September 6 (Di Ziying) Recently, a special conference on global advanced battery forward-looking technology was held in Yibin, Sichuan. The conference brought together more than 600 representatives of top corporate experts and industry scholars to conduct discussions around the four major directions of full-process safety, all-climate overcharging, all-solid-state batteries, and high efficiency in all working conditions.

Ouyang Minggao, academician of the Chinese Academy of Sciences and professor of Tsinghua University, pointed out in his speech that the current era is driven by the twin engines of the new energy green revolution and intelligent artificial intelligence. It is necessary to continue to deepen the core technology of battery cells, and promote continuous breakthroughs and improvements in the power battery technology system through in-depth academic discussions and technical iterations. "China's power battery industry has represented the highest level of development in the world. We are fully equipped with the industrial foundation, technology accumulation and industrial chain advantages to lead the world." He said that in the future, the entire industry must strengthen confidence, focus on innovation, continue to break through core technologies, improve the industrial ecology, dominate industry rules, continue to consolidate its global leadership, and drive high-quality development of the global power battery industry.

Currently, the power battery industry is focusing on multi-scenario and all-working-condition applications, promoting technology from single-point performance breakthroughs to systematic collaborative innovation. Wu Kai, academician of the Chinese Academy of Engineering and chief scientist of CATL, said that global power batteries have entered the TWh (terawatt-hour) era, the cost of electricity has dropped to US$100, and electrification has expanded to multiple application scenarios. The technical needs of each scenario are differentiated. Heavy trucks, ships, robots, and eVTOL respectively face different challenges such as regulatory support, reliability, standard gaps, and thermal safety. Wu Kai foresees that in the future, AI can be used to empower material research and development, strengthen cross-field standard collaboration, create a low-carbon industry closed loop, and promote the implementation of electrification in all scenarios.

BYD Lithium Battery CTO Sun Huajun shared the safety and flash charging practices of blade batteries in all working conditions and multiple scenarios. He pointed out that blade batteries take safety standards that exceed national standards as the core and rely on the "source-prevention-management-control" safety system to ensure full-process safety in ultra-large-scale applications. At present, the second-generation blade battery overcomes the two major problems of flash charging and low-temperature adaptation, achieving fast flash charging in 5 minutes at normal temperature, full charge in 9 minutes, and only 3 minutes of recharge under low temperature conditions, covering all working conditions and efficient applications in passenger cars, commercial vehicles, and energy storage fields.

As the core outcome of the conference, the China All-Solid-State Battery Industry-Academia-Research Collaborative Innovation Platform and the New Generation Power Battery Intellectual Property Alliance released the report "Power Battery Forward-looking Technology and Intellectual Property Strategy", proposing differentiated layout plans for solid-state batteries and sodium batteries, and building a full-process collaboration and multiple intellectual property operation model.

It is understood that the Global Advanced Battery Forward-looking Technology Conference has been held for five consecutive years and is a recognized technology benchmark in the field of power batteries. This conference is hosted by the China All-Solid-State Battery Industry-Academic-Research Collaborative Innovation Platform and Academician Ouyang Minggao Workstation. It closely follows the key window period for the high-quality leap of the industry in the "15th Five-Year Plan", accurately studies and judges the trend of technology iteration, and provides a communication platform to promote China's power battery industry to continue to lead the world and achieve high-quality development.
