Fast Technology reported on September 1 that the 2024 World Power Battery Conference was held in Yibin, Sichuan.
Zeng Yuqun, chairman of Ningde Times, said in his speech that the power battery industry must enter a stage of high-standard development.
He believes that the first priority is high safety, which is the lifeline of the industry’s sustainable development.
The current safety factor of some power batteries is far from enough.
The fire incidence rate of new energy vehicles in 2023 will be 0.
96 per 10,000.
The number of new energy vehicles in China has exceeded 25 million, and the number of batteries loaded is billions.
If security issues are not solved, the consequences will be disastrous.
In Zeng Yuqun’s view, battery safety is a systematic project that needs to be improved in terms of material thermal stability.
He called for the establishment of an absolute red line of safety standards,”putting competition aside first and putting consumer safety standards first.
” Talking about the development of solid-state batteries, Zeng Yuqun said that the key to all-solid-state batteries lies in materials and chemical systems, and the most difficult thing is the interface problem, that is, ion transport between particles.
We use technology and manufacturing maturity of 1-9 as the evaluation system.
The all-solid-state battery research and development in Ningde era is currently at level 4.
