Key Takeaways
1. CATL plans to begin large-scale production of sodium-ion batteries in 2026 to take advantage of rising lithium prices.
2. The Naxtra sodium-ion battery line will serve various applications, including electric vehicles and energy storage systems.
3. The production of sodium-ion cells has become more cost-effective compared to traditional lithium ferrophosphate (LFP) batteries.
4. The Naxtra sodium-ion battery has an energy density of 175 Wh/kg and performs well in extreme temperatures (-40℃ to 70℃).
5. CATL claims that electric vehicles using Naxtra batteries could achieve over 300 miles of range on a single charge, with initial deliveries planned for 2026.
The largest battery manufacturer in the world, CATL, is set to capitalize on increasing lithium prices by commencing large-scale production of sodium-ion batteries in 2026. The groundbreaking Naxtra line of sodium-ion batteries will be utilized in electric vehicles, energy storage systems, commercial transport, and even battery swap stations on a large scale.
Shifting Plans Amid Lithium Prices
Since the peak in 2022, the significant decline in battery-grade lithium carbonate prices has pushed CATL to downplay its sodium-ion battery production strategies. Although CATL developed sodium-ion cells with energy density comparable to LFP batteries, the supply of lithium was artificially constrained due to the Chinese government’s suspension of mining operations. This intervention has contributed to a gradual recovery in lithium prices.
New Opportunities for Naxtra
With the end of the downturn for lithium, CATL has accelerated its plans for mass production of the Naxtra sodium-ion battery line. Given that sodium-ion cells have become less expensive to produce compared to conventional lithium ferrophosphate (LFP) batteries, customers have begun informing CATL that they are ready to receive their orders.
The Naxtra sodium-ion battery boasts an impressive energy density of 175 Wh/kg, nearly matching the energy density of LFP batteries commonly found in electric cars and energy storage solutions. Recently, sodium-ion starter batteries have even appeared on Amazon, which perform better in cold conditions than typical 12V car batteries.
Promising Features and Performance
CATL emphasizes that the Naxtra sodium-ion battery line is primed to shine alongside lithium batteries as early as next year. With a remarkable temperature retention range of -40℃ to 70℃, Naxtra has also become the first commercial sodium-ion battery to meet China’s stringent safety and performance regulations.
According to CATL, an electric vehicle fitted with their sodium-ion battery could achieve a range of over 300 miles on a single charge, even in extreme cold. This claim will be tested in 2026 when the initial Naxtra packs are scheduled for delivery to various undisclosed clients.
