BYD, a prominent Chinese EV manufacturer, is making significant strides in the development of all-solid-state batteries for electric vehicles. The company anticipates launching its first EVs equipped with this cutting-edge battery technology by 2027. Although BYD has already achieved breakthroughs in this area, widespread adoption may take a few more years.
Sun Huajun, the Chief Technology Officer of BYD’s battery division, recently shared an updated timeline for the company’s progress at the 2nd annual China All-Solid-State Battery and Development Summit. According to Sun, BYD’s initial EVs featuring all-solid-state batteries are expected to debut in 2027, with a limited production phase planned between 2027 and 2029. By 2030, BYD aims to scale up production and incorporate the new battery tech on a larger scale.
In the initial phase, BYD will utilize sulfide-based solid-state batteries, primarily targeting high-end vehicles. These batteries are known for their longevity, fast charging capabilities, and enhanced stability. Interestingly, a report last November suggested that CATL, another major player in the EV battery market, is also working on sulfide-based all-solid-state batteries.
BYD has been researching all-solid-state battery technology since 2013 and has made significant progress in verifying mass production feasibility with various cell systems and materials. Last year, the company commenced testing solid-state battery cells with capacities of 20 Ah and 60 Ah.
As the world’s second-largest EV battery manufacturer, behind CATL, BYD holds a substantial market share. While CATL leads with a 37.9% share, BYD follows closely at 17.2%. Despite the advancements in all-solid-state batteries, BYD plans to continue producing lithium iron phosphate (LFP) batteries for the next 15 to 20 years due to supply and cost considerations.
The introduction of all-solid-state batteries is expected to initially target luxury models within BYD’s portfolio, such as the Denza and Yangwang brands. These batteries offer the promise of higher energy density, faster charging times, and improved safety compared to traditional lithium-ion batteries.
While challenges such as high costs and production scalability remain, companies like BYD and CATL are at the forefront of all-solid-state battery development. Other automakers, including Hyundai, Honda, Mercedes-Benz, Toyota, Stellantis, and Nissan, are also investing in this next-generation battery technology.
As the market continues to shift towards electric vehicles, the development of advanced battery technologies like all-solid-state batteries will play a crucial role in shaping the future of transportation. With various companies vying to lead the way in this space, the race towards widespread adoption of all-solid-state batteries is well underway.
