CATL has poured a bucket of cold water on the hype around solid-state batteries: the technology is not close to broad commercialization, and the company says true large-scale production will not arrive before 2030. In practice, that means the first wave will likely stay trapped in premium cars priced above 250,000 yuan, while mainstream EV buyers keep waiting. That is the opposite of the ”coming soon” narrative many battery-watchers like to recycle.
In an interview with Caijing Magazine, CATL chairman Robin Zeng said the company sees a threshold of 1 million vehicles before solid-state batteries can be called commercially scaled. He also said the biggest obstacles are still technical, which is a polite way of saying the industry is nowhere near turning lab demos into reliable, affordable mass output.
CATL puts solid-state batteries at level 4
Zeng described the technology using the industry’s readiness scale, known as TRL, which runs from 1 to 9. CATL currently places solid-state batteries at level 4, a stage that suggests progress, but also a lot of engineering left before factories can churn them out at scale. For comparison, that is a long way from the kind of maturity investors tend to imagine when they hear ”next-generation battery.”
The company’s framing is useful because it cuts through the usual battery-market fog. Solid-state cells promise better safety and energy density, but that does not automatically solve yield, supply chain, or cost problems. The same story has played out before with plenty of hardware categories: the prototype wins the headlines, and the manufacturing line wins the war.
Premium EVs get first dibs
CATL says the first installations are likely to target higher-end vehicle platforms rather than mass-market models. That fits the economics: expensive batteries usually debut where automakers can hide the cost in a luxury badge, fatter margins, or both. For everyone else, the sticker shock is still the enemy.
- Commercial-scale threshold: 1 million vehicles
- Earliest large-scale commercialization: no earlier than 2030
- Initial pricing target: segments above 250,000 yuan ($36,920)
- Current technology readiness level: 4
CATL still rules the battery table
None of this changes CATL’s status as the industry heavyweight. The company remains the dominant force in batteries, and that matters because the firms that control today’s volume lines usually set the pace for tomorrow’s chemistry too. If CATL is cooling expectations, competitors promising near-term solid-state miracles will need to show more than glossy roadmaps.
Data released earlier by the China Passenger Car Association also showed CATL holding its lead in battery market share. That kind of installed power gives the company room to be patient: it can keep shipping conventional packs while solid-state matures slowly in the background.
The real race is manufacturing, not the lab
The next question is whether any automaker can jump from pilot runs to dependable scale faster than CATL’s timeline suggests. If history is a guide, battery chemistry tends to move at the speed of factories, not slide decks, and that usually disappoints the people counting on a sudden breakthrough. Expect more claims, more pilot fleets, and a lot more waiting.
