CATL’s second-generation sodium-ion cells have achieved a production cost of $42/kWh—reaching parity with lithium iron phosphate (LFP) cells for the first time. The milestone, reported at the company’s annual technology day, positions sodium-ion as a commercially viable alternative for stationary energy storage where energy density requirements are less stringent than in automotive applications.
Supply Chain Advantages
Sodium-ion chemistry eliminates dependence on lithium, cobalt, and nickel—materials subject to significant supply chain concentration and price volatility. The cells use abundant iron, manganese, and sodium, with raw material costs 70% lower than equivalent LFP formulations. BYD and HiNa Battery have also announced sodium-ion products entering mass production in 2026.
The pricing milestone is expected to accelerate adoption in grid storage, telecommunications backup, and off-grid applications, particularly in price-sensitive emerging markets.
