Key Players
Competitive Landscape
The copper foil market brings together large-scale ED foil producers, battery-grade specialists and regional PCB foil suppliers. Defu Technology and Nuode Investment compete on large-scale electrodeposited foil production for Chinese battery makers, and Furukawa Electric adds established grade capacity. SK Nexilis, Lotte Energy Materials and Solus Advanced Materials supply battery-grade ultra-thin foil. Rivalry through 2036 will turn on thickness qualification, conductivity and supply diversification.
Producers kept adding capacity during 2025 and 2026 even as copper input costs climbed. In July 2026, Metalnomist reported that global lithium-ion battery copper foil shipments reached 1.302 million tonnes in 2025, up 41.7% from 2024, citing EV Tank. SK Nexilis and other battery-grade producers pushed the combined share of 5 micron and 4.5 micron ultra-thin foil to 24% of shipments in 2025. South Korea's trade ministry raised battery-industry support to about KRW 7.9 trillion for 2025, and the UK's AESC Sunderland gigafactory investment of about £1 billion added downstream battery demand in Europe. Producers deciding capacity locations over the forecast period will weigh thickness qualification speed, conductivity and secure copper sourcing.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| July 2026: Metalnomist reported battery copper foil shipments of 1.302 million tonnes for 2025, citing EV Tank. | Electric vehicle and battery output keeps rising. | Ultra-thin foil is gaining share inside shipments. | Producers outside China can gain buyers seeking diversified supply. |
| June 2026: IEA reported 108 GW of global battery storage additions for 2025. | Grid storage build-out adds a new foil demand base. | Storage cell makers are scaling alongside EV cell makers. | Foil producers can diversify beyond EV-only battery demand. |
| May 2025: UK government and partners committed about £1 billion to the AESC Sunderland gigafactory. | National governments are backing battery cell capacity. | Regional battery capacity is spreading beyond East Asia. | Foil producers can supply newly built gigafactories directly. |
| January 2025: South Korea raised battery-industry support to about KRW 7.9 trillion for 2025. | Government support is lifting battery capacity targets. | Battery-grade thin foil demand is rising alongside capacity. | Producers such as SK Nexilis can expand qualified thin-foil supply. |

Defu Technology and Nuode Investment both lead in large-scale ED foil production, and price level, home market and customer mix set the two apart. SK Nexilis and Lotte Energy Materials compete more on battery-grade ultra-thin foil than on scale alone. Furukawa Electric and Kingboard Holdings serve established-grade and PCB applications that follow the foil type.
Who leads the copper foil market?
Leadership in copper foil production is shared by producers with different strengths in foil-type coverage, thickness range and application focus. China-based ED foil leaders such as Defu Technology and Nuode Investment account for a large share of global electrodeposited foil output, and SK Nexilis reports strong growth in battery-grade ultra-thin foil. Supplier rank is likely to follow thickness qualification speed and supply diversification over the coming decade.
Which companies have documented capacity or shipment evidence?
Metalnomist reports battery-grade copper foil shipment and thickness-mix data covering major East Asian producers. SK Nexilis and Lotte Energy Materials publish specifications for battery-grade ultra-thin foil. Buyers reviewing Solus Advanced Materials, Kingboard Holdings and Shandong Jinbao Electronics can ask for full specifications and qualification samples before ordering.
What should buyers evaluate before approving a supplier?
Battery and electronics makers should test conductivity, thickness tolerance, tensile strength and tear resistance before approving a foil supplier. Supply diversification outside a single region also matters, given that China supplied 82.9% of global lithium-ion battery copper foil shipments in 2025. Plants tend to choose producers that run qualification samples on the buyer's own cell or board design before full orders.
How is competition expected to change through 2036?
Competition is expected to tighten between East Asian and Western producers as battery and electronics makers diversify supply. Trade measures, such as the 50% Section 232 copper tariff in the United States, may push buyers to qualify more than one regional source. Grid battery storage growth is expected to reward producers of thin, high-conductivity foil through 2036.

Research Methodology
Copper foil producers profiled here represent the present supplier mix, grouped by role in grade production, battery and thermal-grade specialty foil, or regional and PCB-grade supply. Primary research covers foil producers, battery and PCB makers, and procurement teams. Desk research draws on producer filings, trade press shipment data, government battery-policy announcements and trade-tariff notices. Estimates are tested against installed capacity, shipment volumes and country battery-policy conditions.
