Formerly Iljin Materials; makes electrolytic copper foil used in lithium-ion battery anodes and PCBs, now under Lotte Group.
Copper foil is priced as a metal cost plus a processing fee, so copper price moves pass through to customers and profit lies in the conversion fee and yield; customers must qualify the foil on each battery line. Lotte group took over in 2021 and is expanding plants overseas, including in Malaysia.
Moat: narrow (process know-how, customer qualification). Ultra-thin copper-foil production requires precise process know-how battery makers must qualify.
