The Chinese battery manufacturer CATL has signed a significant agreement to supply sodium-ion batteries. Its partner is the Chinese energy storage provider HyperStrong. According to a company statement, the contract covers a volume of 60 gigawatt-hours over a three-year period. Currently, this is the largest known order for sodium-ion batteries.
Major Order Signals Market Growth
With this agreement, CATL is positioning itself in the growing stationary energy storage market. The company claims to have overcome technical challenges throughout the production chain, enabling large-scale deliveries.
CATL reports that it has invested approximately 10 billion yuan (just under 1.5 billion USD) in sodium-ion technology development since 2016. The goal is to establish sodium-ion technology as an alternative to lithium-ion batteries, particularly for applications requiring longer storage durations. The current generation of cells uses a platform design identical in dimensions to lithium-ion cells. This is intended to reduce adaptation costs.
CATL expects sodium-ion batteries to achieve a 30- to 40-percent market share in the long term.
