CATL, the world's largest battery maker, has confirmed it plans to begin small-batch production of all-solid-state batteries in 2027, with volume manufacturing targeted for around 2030, according to PCauto. The timeline, which the company has communicated consistently in recent briefings, puts CATL in line with a broader industry push toward the next-generation battery technology.
The company is focusing on a sulfide-based electrolyte system, a route widely seen in the industry as the most practical for vehicle integration. CATL has previously stated that its solid-state cells could reach an energy density of 500Wh/kg, a significant jump from current mainstream liquid-electrolyte lithium-ion batteries, which typically range from 200 to 300Wh/kg. Such an increase could substantially extend the driving range of battery-electric vehicles (BEVs).
Engineering hurdles remain
CATL's all-solid-state development team now exceeds 1,000 researchers, who are working on challenges such as solid-solid interface stability and production yield rates. The company acknowledges that significant engineering work remains before the technology is ready for mature mass production, including production line reconfiguration, cost control and long-term cycle performance.
Solid-state batteries replace the flammable liquid electrolyte with a solid material, theoretically reducing risks of leakage and thermal runaway. However, the technology faces high industrialisation barriers beyond material stability, including the need for new manufacturing equipment and processes.
The 2027-2030 window has become a focal point for the industry, with multiple battery makers and automakers in China and abroad pursuing similar timelines. The pace of solid-state battery commercialisation will directly influence automakers' development plans for next-generation long-range models, as they decide which battery architectures to design around.
Industry-wide race
CATL is not alone in targeting this timeframe. Several Chinese battery manufacturers, including WeLion and Ganfeng Lithium, have announced their own solid-state roadmaps, while automakers such as Toyota and Volkswagen-backed QuantumScape are also working on the technology. The competitive landscape suggests that the first wave of solid-state vehicles could arrive in the early 2030s.
For now, CATL's confirmation provides a concrete reference point for the industry. The company's scale and manufacturing expertise mean its timeline could serve as a benchmark for suppliers and automakers planning their own solid-state strategies. The technology, once mature, could reshape the economics of long-range electric vehicles, potentially reducing the need for heavier battery packs and enabling faster charging.
PCauto noted that CATL's roadmap has remained consistent across multiple public communications, signalling confidence in its technical approach. The company's sulfide-based chemistry is considered more compatible with existing lithium-ion manufacturing infrastructure than some alternatives, though it still requires substantial investment in new production equipment.
