BYD CTO predicts sulfide solid-state batteries will begin demonstration between 2027 and 2029

The new energy industry needs to consider sustainable development, avoid blind expansion, and rationally plan production capacity. Sun Huajun pointed out that the research and development of the next generation of batteries, such as solid-state batteries and new materials, should be continuously strengthened. He specifically mentioned sulfide solid-state batteries as one of the development directions, and it is expected that there will be significant breakthroughs in battery life and fast charging. Sun Huajun predicts that sulfide solid-state batteries will begin demonstration between 2027 and 2029, and will be mainly used in mid- to high-end electric vehicles. From 2030 to 2032, sulfide solid-state batteries will enter an expansion period and be widely used in mainstream electric vehicles.
