Batteries are critical components in electric
vehicles and ESS in terms of their share of total cost, their role in
determining performance, and safety. The four key battery materials are cathode
materials, anode materials, electrolytes and separators. Both electrodes use
current collectors to collect and conduct electrons. Copper foil is generally
used for the anode and aluminum foil for the cathode. This report provides a
detailed review of copper foil, particularly battery copper foil, covering
technology, markets, regulations and substitutes, and major manufacturers.
The technology section explains the features of
the manufacturing process, comprising dissolution, electrodeposition and
slitting, and reviews titanium drums and their manufacturers, as well as key
terms such as capacity and yield. It also presents product classifications by
mechanical properties, thickness and width. The discussion of product changes
and trends examines the thinner and wider foil, high strength and high
elongation required by battery manufacturers to achieve their technology
roadmaps. Patent trends by country, company and technology also show that
development is increasingly focused on ultrathin foil and composite current
collectors.
The EV and battery market section presents
regional outlooks for passenger and commercial EVs, battery demand by
application and region, and battery capacity and supply/demand balances by
production region and manufacturer through 2035.
Battery copper foil demand is calculated by
multiplying battery Real Demand (GWh) by foil usage for each application
(tonnes/GWh). Demand is projected to grow at a 12% CAGR from 660,000 tonnes in
2024 to 2.31 million tonnes in 2035, led by LFP-based ESS and commercial
vehicles, which require more foil per GWh. The report presents historical price
trends since 2013 and forecasts based on processing fees (T-values). Reflecting
these forecasts, the global battery copper foil market is projected to reach USD
45.9 billion in 2035.
On the supply side, the report forecasts battery
copper foil capacity by manufacturer and region on an Actual Capacity basis,
incorporating yield and utilization rates. It presents regional supply/demand
balances and maps the supply chain between foil manufacturers and battery
manufacturers. Global supply and demand are expected to approach equilibrium
around 2030, with supply gradually tightening from 2031. As supply/demand
balances, regulations and competitive conditions differ by region, analysis tailored
to business objectives and target customers is essential for sustainable
operations.
When considering capacity expansion, securing
cost competitiveness and responding effectively to regional regulations are
critical issues. The report therefore analyzes how the US IRA AMPC (Section
45X) and PFE/MACR requirements, as amended by the OBBBA in July 2025, the EU
CRMA, and US Section 232 copper tariffs affect battery copper foil costs and
supply chains. It then examines investment site issues in light of these
findings.
All products face potential substitution, and
battery copper foil is no exception. This report examines composite battery
copper foil, solid-state and lithium-metal batteries, and sodium-ion batteries
as representative alternatives, reviewing their current status and outlook to
assess their impact on battery copper foil demand through 2035.
Finally, the report profiles 11 major battery
copper foil manufacturers in Korea, Japan, China and Taiwan, covering their
revenue and operating profit trends over the past three years, business
overviews, production sites and product portfolios.
