Beijing has set a bold target of achieving early scaled application of all-solid-state batteries by 2030, but the world’s largest battery maker, CATL, is urging patience, citing unresolved issues in cost and mass-production technology.
Seven government bodies, including China’s Ministry of Industry and Information Technology, recently published the “15th Five-Year Plan for the New Battery Industry.” The plan explicitly calls for breakthroughs in core technologies such as advanced electrode materials and new electrolytes, with the goal of moving all-solid-state cells from lab prototypes to early commercial deployment within this decade.
The policy push signals China’s intent to maintain leadership in next-generation energy storage. Yet the gap between government ambition and industrial readiness remains wide. CATL’s chairman, Robin Zeng, has repeatedly stressed that the technology is still far from being able to support mass adoption in vehicles.
Speaking at a public event in June, Zeng rated the technology maturity of all-solid-state batteries at level 4 on a 9-point scale, where level 9 denotes full mass-production readiness. He pointed out that manufacturing stability, cost reduction, and performance requirements must be solved simultaneously, making it unlikely that all-solid-state batteries would be scaled to millions of vehicles before 2030.
CATL itself is working toward small-scale production and vehicle validation by 2027. That timeline, however, would still put full commercial rollouts beyond the current decade. The company’s cautious stance stands in contrast to the Chinese government’s aggressive promotion of the technology.
A similar view came from LG Energy Solution. Robert Lee, head of the company’s North American operations, noted during a recent industry forum that mass-producing large all-solid-state cells for electric vehicles presents significant difficulties. He suggested that smaller-format cells for smartphones or specialized applications could reach the market earlier, with automotive use following only after further maturation.
Market researchers share this measured outlook. BloombergNEF projects that all-solid-state batteries will account for only about 10% of global EV and energy-storage battery demand even by 2035. That forecast implies a relatively slow ramp-up, even under optimistic assumptions about technology breakthroughs.
In China, semi-solid-state batteries have already appeared in some production vehicles. But industry experts caution that these are not equivalent to true all-solid-state batteries, which require a completely different electrolyte system. The distinction matters for regulatory planning, investment decisions, and consumer expectations.
Cost remains the single biggest hurdle. Current all-solid-state manufacturing relies on expensive sulfide or oxide solid electrolytes and high-precision stacking processes. Production yields are lower than for conventional lithium-ion cells, driving up per-kilowatt-hour costs. Without a significant reduction in material and equipment costs, scaled automotive use will remain financially unattractive.
Another challenge is fast-charging behavior at low temperatures. While solid electrolytes can improve safety and energy density, many prototypes still show limited performance under subzero conditions. Automakers need consistent cold-weather reliability, and that has yet to be fully demonstrated in large cells.
Supply chain readiness also lags. The global battery industry has invested heavily in lithium iron phosphate and nickel-cobalt-manganese production lines. Switching to all-solid-state chemistry requires new supply channels for raw materials like germanium, sulfur, and specialized polymers. Countries without established sources will face additional procurement risks.
Meanwhile, the Chinese government is not betting exclusively on all-solid-state batteries. The new five-year plan also encourages development of sodium-ion batteries, flow batteries, and long-life lithium batteries. For the latter, the target is to increase charge-discharge cycle life to 15,000 cycles by 2030.
Sodium-ion technology has attracted particular attention because sodium is abundant and cheap. Several Chinese manufacturers have launched commercial sodium-ion cells this year, aiming at two-wheelers and stationary storage applications. Industry analysts view this as a practical complement to all-solid-state batteries, offering near-term cost efficiency while the more advanced chemistry matures.
Flow batteries are being positioned for grid-scale energy storage. Because they use liquid electrolytes stored in external tanks, flow systems can be scaled up by increasing tank size, making them attractive for long-duration discharge applications. China’s growing renewable capacity has pushed utilities to explore such options.
The diversified approach reflects a broader strategic calculation. Governments and companies are wary of anchoring all R&D on a single technology that may face unforeseen production problems. Spreading investment across multiple next-generation battery types reduces technological risk.
In response to the government’s new roadmap, several Chinese solid-state battery startups have announced pilot production lines. Most are still at the stage of producing small prismatic cells for testing, not full-scale automotive packs. Industry observers expect the first commercial products to appear in niche sectors like medical devices or aerospace equipment.
Automakers, for their part, are hedging their bets. Some have formed joint research agreements with battery suppliers to stay close to the technology, while simultaneously refining existing lithium-ion platforms. The expectation is that evolutionary improvements to conventional batteries will remain the dominant growth driver for at least another decade.
Global competition adds another layer. Japan’s Toyota holds one of the largest patent portfolios in solid-state batteries, while South Korea’s Samsung SDI has demonstrated high-energy-density prototypes. As China pushes forward, interoperability standards and intellectual property disputes may become new points of tension.
CATL’s caution does not mean it is standing still. The company is investing heavily in solid-state research centers and has filed patents related to sulfide electrolyte production. But executives have made clear that they will not rush products to market without clear quality and cost advantages.
Ultimately, the 2030 target is best understood as a directional goal rather than a hard deadline. Government plans can accelerate research funding and pilot projects, but they cannot eliminate the fundamental engineering challenges. Reality will likely see all-solid-state batteries introduced gradually, starting in premium vehicles and expanding as costs come down.
For now, the signal from China’s new five-year plan is dual: it expresses long-term confidence in all-solid-state battery potential, while also acknowledging that near-term progress will require parallel development of other battery chemistries. That pragmatic approach may prove to be the industry’s most reliable path forward.
