CITIC Securities: Sodium-ion Battery Growth to Boost Aluminum Foil Demand Amid Tight Supply
CITIC Securities Research has identified the aluminum foil sector as a promising niche within lithium-ion battery materials. The industry exhibits a concentrated competitive landscape, with leading companies holding approximately 38% of the market share. This year, aluminum foil manufacturers have successfully passed on price increases to their customers, with processing fees rising by 1000-1500 yuan per ton. Projections indicate a continued improvement in the supply-demand balance for aluminum foil from the second half of 2026 through 2027, setting the stage for further price increases. Additionally, the commercialization of sodium-ion batteries is advancing significantly, moving from initial development to broader implementation. This transition is expected to heavily benefit the aluminum foil sector, as the established technical routes for aluminum foil in sodium-ion batteries are confirmed, and the unit consumption of aluminum foil is projected to double.
The projected growth in sodium-ion battery adoption, coupled with a concentrated supply chain in aluminum foil manufacturing, suggests a favorable market dynamic for existing players. The ability to pass through cost increases indicates strong pricing power, potentially driven by technological necessity and limited supplier alternatives. Investors and industry participants may consider the long-term implications of this demand surge on raw material sourcing and production capacity expansion, as well as the potential for technological obsolescence if alternative materials emerge. The sector's performance will likely be influenced by the pace of battery technology evolution and broader energy storage market trends over the next decade.
