it home reported on september 1 that zeng yuqun, chairman of catl, delivered a speech at the 2024 world power battery conference which opened today.

zeng yuqun believes that the power battery industry must move into a high-standard development stage, and high safety is the lifeline of the industry's sustainable development. regarding power battery fires and other issues, he believes that the safety factor of some power batteries on the market is far from enough. he called for the establishment of an absolute safety standard red line, "putting competition aside and putting consumer safety standards first."

zeng yuqun also mentioned the current hot topics of solid-state batteries. he believes that the key to solid-state batteries is materials and chemical systems, including technical routes such as soft-pack batteries and cylindrical batteries. the most difficult problem is the interface problem, that is, the ion transmission between particles. "we use the technology and manufacturing maturity of 1-9 as the evaluation system. catl's all-solid-state battery research and development is currently at the level of 4."

the ppt presented by zeng yuqun on site showed that the evtol equipped with catl batteries will make its first flight at the end of 2024.

the 2024 world power battery conference was held in yibin, sichuan province from september 1 to 2. the uae will be the guest of honor for this conference, and nearly 400 guests have confirmed their intention to attend. more than 180 companies including catl, byd, and tesla have confirmed their participation, and guests from power battery and new energy vehicle industry chain companies account for more than 70%.

the conference will hold 6 special meetings, 2 online live interviews, achievement presentations and other activities. it is reported that the special meetings mainly involve advanced battery forward-looking technologies, new energy storage, new energy industry chain supply chain, power battery regulations and standards, etc., and will focus on displaying cutting-edge technology application scenarios such as power tools, low-altitude economy, humanoid robots, and electric ships.

according to previous reports by it home, the 2023 world power battery conference was held in yibin, sichuan from june 8 to 11 last year. a total of 64 projects were signed with a total contract value of 106.3 billion yuan, including 53 green new energy industry projects represented by power batteries, 5 central-local cooperation and industry organization cooperation projects, and 6 new r&d platform projects.
