Contemporary Amperex Technology Co. Ltd. (CATL) has issued a statement refuting online rumors that it will launch mass production of a solid-state battery capable of delivering 2,000 kilometers of driving range in 2027. The Ningde-based battery maker also denied claims that this cell would feature an energy density of 450 kilowatt-hours per kilogram.
In a response provided to CarNewsChina, CATL emphasized that “commercialization of solid-state batteries, including supply chain development, is still some distance away. CATL continues to invest in solid-state battery technology, maintaining industry-leading technical expertise, and anticipates achieving small-scale production by 2027.” The company noted that it has never announced a 2,000-kilometer battery.
This clarification echoes CATL’s 2024 roadmap, which projects small-scale solid-state battery production in China by 2027, followed by mass production and large-scale application in 2030. Industry experts have similarly cautioned that true solid-state battery manufacturing remains years from commercial realization. At the 2025 China Automotive Forum, Wang Fang, chief scientist at the China Automotive Technology Research Centre, reiterated that production of solid-state cells is still “years away.”
Speculation about CATL’s solid-state progress may stem from earlier reports on its “condensed battery,” introduced in April 2023 for passenger aircraft applications. Although this technology achieves energy density up to 500 watt-hours per kilogram, it employs a gel-like condensed-state electrolyte—not a fully solid electrolyte—and bridges the gap between liquid and all-solid-state configurations.
Meanwhile, CATL continues to expand its battery portfolio. In November 2024, it unveiled a 1,000-kilowatt-hour Tectrans battery for heavy-duty trucks. In September 2025, the company launched its Naxtra sodium-ion battery at the Shanghai Auto Show, offering up to 500 kilometers of range at 175 watt-hours per kilogram, with mass production slated for 2026. At the 2025 IAA Munich, CATL introduced its Shenxing Pro battery tailored for European automakers, boasting a WLTP range of 758 kilometers, a 12-year/1,000,000-kilometer lifespan, and just 9% capacity loss after 200,000 kilometers.
Regarding solid-state cells, CATL noted that it has more than a decade of research and development experience in this area, with a leading R&D team and growing investments aimed at resolving remaining engineering challenges.
