China has set a target for the production and large-scale deployment of solid-state batteries by 2030, as part of a new battery-industry road map announced on September 28. The goal reflects Beijing’s desire to carry its current advantage in electric-vehicle batteries into the next generation of storage technologies, but it does not mean that these batteries will become a widely adopted standard in vehicles by the same deadline.
CATL, the world’s largest electric-vehicle battery manufacturer, warns that the path from initial production to mass adoption remains long. Its chairman, Robin Zeng, rated solid-state technology at level four out of nine on a readiness scale, with level nine representing readiness for large-scale production.
Production May Precede Commercial Adoption
CATL has confirmed plans to begin limited production of solid-state batteries in 2027, but indicated that increasing output to substantial levels will be difficult. Zeng had said that the use of these batteries in millions of vehicles is unlikely before the end of the decade, due to continuing performance and cost challenges.
In practice, the batteries may reach limited production lines before becoming available in affordable electric vehicles. This is an important distinction in interpreting the 2030 target: the year may mark the starting point for expanding use, rather than a date when the technology suddenly becomes a comprehensive industry standard.
The Challenge Is Not Just the Materials
China’s road map calls for cost reductions, improved performance and stability, and progress in materials and manufacturing processes. The Ministry of Industry and Information Technology acknowledged weaknesses in the domestic industry, including inadequate innovation and supply-demand imbalances, despite China’s large research and manufacturing base.
The road map is not limited to solid-state batteries; it also covers sodium-ion batteries and flow batteries, improvements in safety and performance at different temperatures, and higher manufacturing quality. It also includes a separate goal to develop long-life lithium batteries capable of reaching 15,000 cycles, without implying that solid-state batteries will reach the same figure.
Why Does This Matter?
The developments show that the race toward solid-state batteries is not about proving that a single cell can be manufactured, but about producing them in large quantities at a price suitable for mass-market vehicles. The warnings also do not come only from outside parties; even CATL, which is preparing for limited production, sees industrial scaling as a separate obstacle.
Semi-solid-state batteries already exist in a limited number of vehicles in China, but their presence does not prove that fully solid-state batteries are ready for widespread adoption. BloombergNEF forecasts cited in the article indicate that solid-state technology may account for only about 10% of combined global demand for electric vehicles and battery storage by 2035. The article also quoted Robert Lee, president of LG Energy Solution in North America, as emphasizing the difficulty of manufacturing large solid-state cells and predicting that the first mass-market applications will emerge outside electric vehicles.
