According to Nengyuanhangye, the '2024 World Power Battery Conference' was held in Yibin, Sichuan today. At the global advanced battery forward-looking technology seminar in the afternoon, Byd Company Limited CTO Sun Huajun delivered a speech. He mentioned that the new energy fund industry needs to consider sustainable development, avoid blind expansion, and rationalize capacity layout. He also mentioned that safety technology must be fully overcome. In terms of battery innovation, he stated that continuous efforts need to be made in the research and development of next-generation batteries, such as solid state batteries and new materials. 'Sulfide solid state battery is one direction,' and it will achieve breakthroughs in battery life and fast charging. Sun Huajun believes that the period from 2027 to 2029 will be the demonstration period for sulfide solid state batteries, mainly targeting high-end electric vehicles. From 2030 to 2032, the sulfide solid state battery will enter an expansion period and will be applied to mainstream electric vehicles.
