CATL Naxtra: what has actually been announced
Naxtra is the most important current sodium-ion platform, but its milestones need labels: product unveiling in 2025, vehicle partnership in early 2026, and full-scale mass production targeted for the end of 2026.
Published specifications
CATL states up to 175 Wh/kg at cell level. In its Changan announcement it reported more than 90% capacity retention at -40°C, stable power at -50°C and a vehicle range above 400 km. These are maker claims for Naxtra, not generic sodium-ion values.
Industrial status
In April 2026 CATL said it had achieved GWh-level industrialisation and addressed water control, hard-carbon gas generation, aluminium adhesion and anode formation. It nevertheless described full-scale mass production as a target for year end.
What it means in Britain
Naxtra validates serious industrial investment. It does not put a replacement battery or sodium car in a UK showroom. Watch for a named European vehicle, homologation, delivery dates and service support before turning the platform into a consumer recommendation.
Questions answered
Is Naxtra already mass-produced?
CATL calls it mass-producible and says GWh-scale industrialisation is achieved; its April 2026 release set full-scale mass production for the end of 2026.
Is it safer than LFP?
CATL publishes strong test results, but cross-chemistry safety needs like-for-like pack tests and operating conditions.
