During the second annual summit on solid-state batteries, the company’s CTO, Sun Huajun, revealed that between 2027 and 2029 a demonstration phase with limited production will take place, with the aim of starting large-scale production in 2030.

The new BYD batteries will be sulfur-based, which promises a longer lifespan, faster charging times, and greater stability.

The future of batteries lies in sulfur

Although BYD has already made significant advances in this technology, mass adoption is expected to take time, as the company clings to the production of LFP (lithium iron phosphate) batteries for the next 15 to 20 years due to cost and supply constraints.

In a context of increasing competition, CATL, the world’s largest EV battery manufacturer, is also developing solid-state batteries and plans to start production in 2027, initially on a small scale.

These batteries have been promoted as “the next generation” of battery technology due to their high energy density, faster charging, and better safety compared to conventional lithium batteries.

Despite its promises, large-scale adoption faces challenges, including high costs and issues in scaling the production of solid electrolyte. In addition to BYD and CATL, other automakers such as Hyundai, Honda, Mercedes-Benz, and Toyota are also in the race to develop this innovative technology.
