BYD will start mass installation of all-solid-state batteries around 2027, company CTO says
On February 15 at the second China All-Solid-State Battery Innovation and Development Summit Forum, Sun Huajun – CTO of the Shenzhen BYD Lithium Battery Co., Ltd., revealed that BYD has rolled off 60Ah all-solid-state batteries from the pilot production line in 2024. The company will start mass demonstration as well as installation of all-solid-state batteries around 2027, and achieve large-scale installation after 2030.
Furthermore, Sun predicts that from the perspective of long-term development, after scale-up, solid-state ternary batteries and liquid-state ternary batteries can be close to the same price.
Earlier in September last year, Sun indicated that he would continue to strengthen the research and development (R&D) of the next generation of batteries, such as solid-state batteries and new materials, with “sulfide solid-state batteries being one of the directions.” Looking forward, Sun believes that 2027 to 2029 is the demonstration period for sulfide solid-state batteries, mainly for mid-to-high-end electric vehicles. From 2030 to 2032, sulfide solid-state batteries will enter the expansion period and will be used in mainstream electric vehicles.
Lian Yubo, BYD’s chief scientist, chief automotive engineer, and dean of the Automotive Engineering Research Institute, echoed similar sentiments, predicting that “three years will be difficult, and five years will be more realistic.”
In addition, Lian shared that due to factors such as cost and material controllability, lithium iron phosphate batteries will not be eliminated in the next 15 to 20 years. “Solid-state batteries will be mainly used in high-end models, empowering each other with lithium iron phosphate batteries, and used in vehicles of different levels.”
AI in battery R&D
The AI era has ushered in a more powerful boost to battery R&D by allowing in-depth mining and analysis of large volumes of data, according to Ouyang Minggao, an academician of the Chinese Academy of Sciences and chairman of the China All-Solid-State Battery Industry-University-Research Collaborative Innovation Platform (CASIP). More specifically, Ouyang predicted that the battery R&D efficiency could be improved by one to two orders of magnitude, saving 70% to 80% of the R&D costs.
CASIP was jointly established by battery giants such as CATL and BYD in January 2024, committed to promoting the academic and industrial development of all-solid-state batteries in China.
