CATL denies rumours of 2,000 km solid-state battery mass production in 2027
CATL officially denied rumours that it will start mass production of solid-state batteries with a 2,000 km range in 2027, as shared by some influencers online. Some also claim this rumour as an official statement from CATL, saying the battery will have a 450 kWh density, which the Ningde-based battery giant also denies.
“Commercialisation (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,” said CATL in a comment sent to CarNewsChina. Moreover, CATL never announced a 2,000 km battery.
This aligns with what CATL announced in 2024, stating that it may start small-scale production of solid-state batteries in China in 2027, with mass production and large-scale application set to begin in 2030.
And industry insiders agree with CATL. In July, at 2025 China Automotive Forum, Wang Fang, Chief Scientist at China Automotive Technology Research Centre, claimed that production of solid-state batteries is still “years away”.
Those rumours most likely originate from recycled news from April 2023, when CATL launched a condensed battery with an energy density of up to 500 Wh/kg, specifically for passenger aircraft.
However, CATL’s condensed battery is not a solid-state battery. The condensed battery technology is an evolution of lithium-based energy storage: it utilises a special condensed-state electrolyte, which exists in a gel-like form, bridging the gap between liquid batteries and all-solid-state batteries.
This doesn’t mean CATL is short of new types of batteries. In November last year, the company introduced a massive 1000 kWh (not a typo) Tectrans battery for heavy-duty trucks. Last month, the company announced that its Naxtra sodium-ion battery, unveiled at the Shanghai Auto Show, can provide a range of up to 500 km, thanks to an energy density of 175 Wh/kg, which is on par with most LFP batteries. Mass production is scheduled for 2026.
At the 2025 IAA Munich, CATL also introduced its new Shenxing Pro battery, localised for European automakers, with a WLTP range of up to 758 km, a lifespan of 12 years or 1,000,000 km, and degradation of only 9% after 200,000 km, according to CATL.
Regarding solid-state batteries, CATL concludes that “The Company places great emphasis on solid-state batteries, with over a decade of research and development experience in this field. It has established a leading R&D team in the industry and is increasing investment in solid-state battery technology, consistently maintaining a leading position in the sector. Currently, the scientific challenges in the solid-state battery industry have been largely resolved, though some engineering issues remain.”
