BYD has officially marked a new phase in battery technology development, confirming its transition to solid-state batteries. For the global market, and especially for Europe, this event does not go unnoticed: the Chinese manufacturer, already holding a strong position in the electric vehicle segment, is now aiming for technology that could change the game. However, as noted by Lian Yubo, BYD’s Chief Scientist, the road to mass adoption of such batteries will be more difficult than expected.
Technological barrier
BYD does not hide the fact that, despite successes in laboratory testing, moving to industrial-scale production of solid-state batteries is accompanied by serious challenges. The main issue is the high cost of materials and the complexity of the manufacturing process. Even for a giant like BYD, production cost remains a critical factor, and the technology so far is available only for a limited number of models.
In the coming years, solid-state batteries will be installed exclusively in premium and exclusive vehicles. According to Lian Yubo, these will be limited series where price is not a decisive factor for the buyer. In particular, the first batch of such batteries will be destined for Yangwang—a BYD sub-brand focused on ultra-exclusive electric cars. For the mass market, including Spain, this means the revolution in affordable electric vehicles with new batteries is postponed at least until the end of the decade.
Critical phase and market prospects
BYD is currently at a stage the company itself describes as the “critical advancement phase.” Research has gone beyond theory, but making the technology affordable and scalable for mass production remains an unresolved challenge. Even in China, where BYD has traditionally outpaced competitors in introducing new solutions, solid-state batteries are not yet ready for widespread commercial use.
For the European and Spanish markets, this means that traditional lithium-ion solutions will dominate in the coming years. BYD will continue to promote its Blade Battery, which has already proven its effectiveness and delivers a range of over 1,000 km according to CLTC. As Lian Yubo notes, both technologies will coexist in the market for at least two decades, and relying solely on solid-state batteries is not yet possible.
Limitations and expectations for Spain
BYD’s plans for launching pilot production of batteries with a sulfide electrolyte are set for 2027, but this concerns small batches for the premium segment. According to the company, mass production may only become a reality by 2030, when costs decrease and the technology becomes more accessible to a wide audience. For the Spanish market, this means the next generations of BYD electric vehicles will continue to rely on proven lithium-ion solutions, while a true revolution in affordability and price is only possible in the long term.
In the context of European competition, it is worth noting that BYD is not the only player striving for leadership in battery technology. Chinese manufacturers are already outpacing their European and American competitors in the pace of innovation, but even they face barriers that cannot be overcome in just one or two years. Against this backdrop, interest in hybrid and alternative solutions remains: hybrid models continue to strengthen their positions in the Spanish market, which confirms the complexity and multi-layered nature of the transition to fully electric platforms.
BYD is already present in Spain with several models, including sedans and crossovers, and is actively expanding its dealer network. However, a mass emergence of electric vehicles with solid-state batteries in the coming years is unlikely. For buyers in Spain, this means that the choice will still revolve around traditional lithium-ion solutions, while new technologies will remain exclusive to select models and demonstration projects.
