BYD: Solid-State Batteries Reach a Critical Development Stage

BYD has announced that solid-state batteries for electric vehicles have reached a crucial stage of development. According to Chief Scientist Liang Yubo, the technology is progressing rapidly, although several technical challenges still need to be resolved before it can be adopted on a large scale.

Speaking at a conference on April 7, Liang Yubo emphasized the importance of building a complete technological ecosystem rather than focusing only on improving individual battery components. He highlighted that future efforts should concentrate on enhancing driving range, battery lifespan, and charging speed—key factors that will define next-generation EV batteries.

However, BYD does not see solid-state batteries as the only path forward. The company plans to continue investing in multiple battery technologies, including:

• Liquid lithium-ion batteries
• Sodium-ion batteries
• Advanced lithium battery systems

According to BYD, these technologies should complement each other, helping accelerate the transition to more efficient and affordable electric vehicles.

Looking ahead, BYD aims to begin limited production of sulfide-based solid-state batteries by 2027, with mass production expected around 2030. Initially, these advanced batteries will be introduced in premium models under BYD’s sub-brands:

• Yangwang
• Denza

This phased rollout strategy suggests that solid-state battery technology will first appear in high-end vehicles before gradually expanding to mainstream segments.
