BYD plans to commence “demonstration use” of all-solid-state batteries by 2027, with large-scale adoption anticipated post-2030, according to Chief Technology Officer Sun Huajun. Speaking at a recent forum on all-solid-state batteries, Sun noted that industry-wide progress is advancing at a comparable pace.
In 2024, BYD’s power battery installations reached 153.7 GWh, securing a 17.2% share of the global market, second only to Contemporary Amperex Technology Co. Ltd. (CATL), which held 37.9%. CATL’s chief scientist, Wu Kai, indicated in April 2024 that the company aims for small-scale production of all-solid-state batteries by 2027, though large-scale manufacturing faces challenges, including cost.
Sun highlighted that BYD’s development of all-solid-state batteries focuses on sulfide electrolytes, chosen for their cost-effectiveness and process stability. The company began research in this area in 2013, progressing from initial material exploration to prototype validation by 2016, and by 2024, producing trial products with single-cell capacities of 20 Ah and 60 Ah.
Addressing cost concerns, Sun emphasized that the high expenses associated with sulfide electrolytes are primarily due to low production volumes. He stated, “It doesn’t really make a lot of sense to talk about cost in the absence of volume.” Sun anticipates that with scaled production, the costs of solid-state ternary batteries could align with those of liquid-based counterparts.
