BYD: Solid-State Batteries Have Reached a Critical Stage
Solid-state batteries for electric vehicles have reached a key development milestone, according to Liang Yubo, Chief Scientist at BYD. He noted that the technology is advancing rapidly, but the industry still needs to address several technical challenges before widespread adoption becomes possible.
At a conference on April 7, Liang Yubo emphasized the need for companies to develop a comprehensive technological chain rather than focusing solely on improving individual battery components. He suggested prioritizing improvements in range, service life, and charging speed for next-generation batteries.
However, BYD believes that solid-state batteries are not the only path forward. The company will continue investing in liquid lithium-ion batteries, sodium-ion solutions, and further advancements in lithium battery technology. According to BYD, these technologies should complement each other and accelerate the transition to more efficient electric vehicles.
BYD plans to begin limited production of sulfide-based solid-state batteries in 2027, with mass production expected around 2030. These batteries will initially be introduced in premium Yangwang and Denza models.
