CATL formally denied rumours that it’s going to begin mass manufacturing of solid-state batteries with a 2,000 km vary in 2027, as shared by some influencers on-line. Some additionally declare this hearsay as an official assertion from CATL, saying the battery can have a 450 kWh density, which the Ningde-based battery large additionally denies.
“Commercialisation (of solid-state batteries), together with provide chain growth, continues to be a ways away. CATL continues to spend money on solid-state battery know-how, sustaining industry-leading technical experience, and anticipates attaining small-scale manufacturing by 2027,” stated CATL in a remark despatched to CarNewsChina. Furthermore, CATL by no means introduced a 2,000 km battery.
This aligns with what CATL introduced in 2024, stating that it might begin small-scale manufacturing of solid-state batteries in China in 2027, with mass manufacturing and large-scale utility set to start in 2030.
And {industry} insiders agree with CATL. In July, at 2025 China Automotive Discussion board, Wang Fang, Chief Scientist at China Automotive Know-how Analysis Centre, claimed that manufacturing of solid-state batteries continues to be “years away”.
These rumours more than likely originate from recycled information from April 2023, when CATL launched a condensed battery with an power density of as much as 500 Wh/kg, particularly for passenger plane.
Nonetheless, CATL’s condensed battery isn’t a solid-state battery. The condensed battery know-how is an evolution of lithium-based power storage: it utilises a particular condensed-state electrolyte, which exists in a gel-like type, bridging the hole between liquid batteries and all-solid-state batteries.
This doesn’t imply CATL is wanting new forms of batteries. In November final yr, the corporate launched an enormous 1000 kWh (not a typo) Tectrans battery for heavy-duty vans. Final month, the corporate introduced that its Naxtra sodium-ion battery, unveiled on the Shanghai Auto Present, can present a variety of as much as 500 km, due to an power density of 175 Wh/kg, which is on par with most LFP batteries. Mass manufacturing is scheduled for 2026.
On the 2025 IAA Munich, CATL additionally launched its new Shenxing Professional battery, localised for European automakers, with a WLTP vary of as much as 758 km, a lifespan of 12 years or 1,000,000 km, and degradation of solely 9% after 200,000 km, based on CATL.
Concerning solid-state batteries, CATL concludes that “The Firm locations nice emphasis on solid-state batteries, with over a decade of analysis and growth expertise on this discipline. It has established a number one R&D group within the {industry} and is rising funding in solid-state battery know-how, persistently sustaining a number one place within the sector. At the moment, the scientific challenges within the solid-state battery {industry} have been largely resolved, although some engineering points stay.”
