As a core raw material for aluminum electrolytic capacitors, aluminum electrode foil is widely used in consumer electronics, home appliances, new energy vehicles, energy storage, 5G base stations, and AI servers. Its market prosperity is directly linked to the development pace of the electronics manufacturing and new energy industries.
In 2026, the global aluminum electrode foil industry completely broke free from the slump caused by overcapacity, exhibiting a new trend of steady growth in total demand, regional differentiation in supply and demand, and structural price increases. The characteristics of traditional demand supporting the market and emerging demand surging became increasingly apparent, and the industry officially entered a stage of high-quality supply and demand matching.
In 2026, the global aluminum electrode foil market demand maintained positive growth, with growth momentum gradually shifting from traditional consumer electronics to emerging fields such as new energy and high-end computing infrastructure, achieving steady expansion. Industry data shows that global electrode foil demand has increased significantly compared to previous years, with total global demand expected to reach 471.49 million square meters in 2026, and the market size exceeding 27.39 billion yuan, representing a significant increase compared to 2022, highlighting the industry's continued growth potential.
The demand side exhibits a dual pattern of "stabilized traditional demand and explosive growth in emerging sectors." The core growth drivers come from the new energy and high-end electronics sectors: On the one hand, the new energy vehicle, photovoltaic energy storage, and charging pile industries continue to experience high growth, leading to a sustained increase in demand for high-voltage, large-capacity aluminum electrode foil for vehicle capacitors and energy storage capacitors; on the other hand, the large-scale deployment of AI servers, big data centers, and 5G communication equipment is driving rapid growth in demand for high-end ultra-thin, high-stability electrode foil, with related sub-sectors showing annual growth rates far exceeding the industry average.
Notably, the rapid commercialization of sodium-ion batteries has brought a new growth curve to aluminum electrode foil. Compared to lithium batteries, sodium-ion batteries require twice the amount of aluminum foil per GWh, significantly expanding the market space for high-end electrode foil and becoming a significant new driver of industry demand expansion in 2026.
From a regional perspective, global aluminium electrode foil production capacity is highly concentrated in the Chinese market. Leading domestic companies, leveraging mature etching and formation processes, a complete industrial chain, and cost advantages, occupy the vast majority of global production capacity, making China the core global electrode foil supply base.
Japanese and South Korean companies focus on high-end, high-value-added products, with limited production capacity, primarily supplying their domestic high-end electronics and automotive markets.
In Europe and the US, production capacity continues to shrink, with domestic supply gaps heavily reliant on imports, and virtually no new capacity being released. Simultaneously, industry entry barriers continue to rise; stricter environmental regulations and tighter energy consumption standards are leading to the elimination of small and medium-sized production capacity, further increasing the concentration of production capacity among leading companies, resulting in weak growth in global effective supply.
From the demand side, demand exhibits a globally dispersed pattern. The Asia-Pacific region remains the world's largest consumer market, with consumer electronics and new energy industries in China, Southeast Asia, Japan, and South Korea supporting core demand.
The European and American markets are driven by upgrades in new energy vehicles, energy storage, and high-end industrial control equipment, leading to a continued increase in import demand for high-end electrode foil. Upgrades in home appliances and basic electronics industries in emerging markets are driving a steady release of demand for mid-to-low-end electrode foil.
Overall, the global supply-demand mismatch will be prominent in 2026: the supply and demand for mid-to-low-end general-purpose electrode foil will be basically balanced, with a slight surplus in some regions; however, there will be a shortage of high-end automotive-grade, high-voltage energy storage, and AI server-specific electrode foil production capacity, unable to quickly match the explosive growth in emerging demand, becoming the core contradiction in the industry's supply-demand structure.
In 2026, the aluminum electrode foil market departed from a general price increase and decrease pattern, exhibiting an overall high-level fluctuation with significant structural differentiation. The core logic stemmed from rigid supply, upgrading demand structure, and supportive raw material costs. The average industry price for the year increased by 8%-15% compared to 2025, demonstrating significantly greater price resilience than in previous years.
Price differences were evident among sub-categories. The price trend of low-to-mid-end ordinary electrode foil remained relatively stable, mainly following fluctuations in aluminum ingot raw material prices. Processing fees remained low, and ample supply and demand limited room for price increases, resulting in overall stability. Meanwhile, high-end electrode foil prices continued to strengthen, with automotive-grade, energy storage, and AI server-specific high-end products showing more significant increases, reaching 15%-20% annually and maintaining a high premium over the long term.
Looking at the price rhythm throughout the year, the first half of 2026 saw a steady rise in high-end electrode foil prices due to concentrated stockpiling in the new energy industry chain and the return of overseas orders. In the second half of the year, market demand stabilized, coupled with the landing of a small amount of new compliant production capacity, leading to a high-level fluctuation phase with no significant decline.
The core factors supporting the firm prices are, on the one hand, the industry's inventory has been at a low level for a long time, resulting in insufficient supply elasticity; on the other hand, the high-end demand continues to surge, and the supply-demand gap is difficult to fill in the short term. At the same time, the rigid increase in the cost of raw materials such as aluminum ingots provides solid bottom support for the price of electrode foil.
