China Targets Mass Production of Solid-State Batteries by 2030, CATL Warns of Hurdles
CATL chairman rates solid-state technology at level four of nine on a readiness scale, citing cost and performance obstacles.
China has established a national goal to achieve large-scale deployment of solid-state batteries by 2030, aiming to extend its lead in electric vehicle technology. However, CATL, the country’s largest battery manufacturer, has cautioned that significant cost and manufacturing challenges remain before these batteries can reach mass adoption.
What Happened
A new battery industry roadmap released by China’s Ministry of Industry and Information Technology on September 28 sets the target for large-scale solid-state battery deployment by 2030. The initiative seeks to leverage China’s existing advantage in conventional batteries to dominate the next generation of energy storage technology. The ministry acknowledged current industry shortcomings, including gaps in innovation and imbalances between supply and demand.
CATL Chairman Robin Zeng previously rated solid-state technology at level four out of nine on a readiness scale, where nine represents mass-production readiness. Zeng indicated that adoption in millions of vehicles was unlikely before the end of the decade due to persistent obstacles in performance and cost. While CATL has confirmed plans to begin limited production of solid-state batteries in 2027, the company noted that scaling to larger volumes would be difficult.
Why It Matters
The distinction between limited production and mass-market availability is critical for consumers and the broader EV market. While semi-solid-state batteries are already appearing in limited numbers in China, these introductions do not signal that all-solid-state batteries are ready for widespread use. BloombergNEF forecasts that solid-state technology will account for only 10% of combined global EV and battery-storage demand by 2035, suggesting that the 2030 target may represent a starting point for broader integration rather than an industry-wide standard.
This national push aligns with China’s history of using five-year plans to coordinate economic and industrial priorities. The previous cycle, spanning 2021–2025, helped China account for 70% of global electric car production by its end. The new 2026–2030 roadmap aims to carry this dominance forward, but achieving affordable solid-state batteries in reasonably priced cars remains the true benchmark for success.
The Bottom Line
China’s 2030 target for solid-state battery deployment is ambitious but faces substantial engineering and economic hurdles. CATL’s cautious assessment and external forecasts indicate that while limited production may begin soon, mass adoption in affordable vehicles will likely lag behind the national deadline.
