On May 15, 2026, Wanshun New Material announced a strategic investment of 300 million RMB to establish two subsidiaries dedicated to the production of high-dyne battery aluminum foil for sodium-ion batteries. The company's self-developed high-dyne foil maintains a surface dyne value exceeding 60, which significantly improves slurry adhesion, charge/discharge efficiency, and cycle stability.
Since the second half of 2025, Wanshun has been continuously supplying small batches of this advanced aluminum foil to downstream customers for new sodium-ion battery applications. This move marks Wanshun New Material's full-scale entry into the sodium battery materials sector.
For B2B buyers in the energy storage and electric vehicle supply chains, this development indicates a maturing sodium-ion battery ecosystem. The enhanced adhesion and stability offered by high-dyne foil can lead to longer-lasting batteries and reduced manufacturing defects, potentially lowering total cost of ownership for end products. As sodium-ion batteries gain traction as a cost-effective alternative to lithium-ion, securing reliable suppliers of specialized components like high-dyne aluminum foil becomes a competitive advantage.
