Huachuang and Cornex Ink Major Lithium-Ion Battery Copper Foil Deal

Copper Foil

Huachuang New Material and Cornex have signed a strategic lithium-ion battery copper foil deal, securing 150,000t of supply over five years. The agreement, finalized on April 27, underlines the accelerating demand for copper foil in China's booming battery and new energy vehicle (NEV) industries. Huachuang, a subsidiary of Huayou Group, will fulfill the order from its three major production bases across China.

Copper Foil Supply Grows with NEV Expansion

China’s lithium-ion battery copper foil deal volume reflects its growing production capacity. The country’s total refined copper foil capacity hit 2.24mn t/yr in 2024, with 1.4mn t/yr dedicated to lithium-ion battery production. Rising NEV output and energy storage battery installations are driving this surge. From January to March 2025, NEV production reached 3.182mn units, a 50% increase year over year.

Cornex Ramps Up as Demand Accelerates

Cornex, though holding just 0.54% of China’s battery installations, is expanding its market role through this copper foil partnership. The deal positions the firm to meet future EV battery demand, where a single vehicle requires up to 38kg of copper foil. Meanwhile, China's total lithium-ion battery copper foil shipments are projected to reach 1.1mn t/yr in 2025.

The Metalnomist Commentary

This lithium-ion battery copper foil deal signals sustained growth in China’s battery supply chain. With copper foil emerging as a critical input, strategic partnerships like Huachuang and Cornex’s will shape regional and global battery material markets in 2025 and beyond.
