TREE NEWS update: Chinese sodium-ion battery makers are accelerating overseas expansion, shifting from product sales to ecosystem building. On Sept 2, Zhongke Haina signed a strategic agreement with South Korea’s VOLTA to advance a 5-year, 10GWh supply deal following a 15MWh storage project. Recent months saw CATL land a European GWh-order, Xingkong Na-Dian form a JV with Germany’s豪雅集团, and Camel Group secure European automaker contracts. Since Sept 1, sodium-ion batteries have a dedicated customs code, boosting exports.
Chinese sodium-ion battery firms accelerate overseas expansion
The shift from one-off product sales to multi-year supply deals and joint ventures signals that Chinese sodium-ion firms are moving to lock in overseas market positions, not just chase orders. The new customs code removes a bureaucratic hurdle, making export logistics cleaner and potentially accelerating deal flow. For incumbents in lithium-ion and regional battery supply chains, this is a competitive signal worth tracking. The open question is whether European and Korean partners are treating sodium-ion as a strategic hedge or a core roadmap, as that will shape how fast these agreements translate into real capacity.
