Lotte Energy Materials
Lotte Energy Materials, formerly Iljin Materials, makes electrodeposited copper foil (Elecfoil) used as the anode current collector in lithium-ion batteries. Lotte Chemical acquired it in 2023. Its strength is ultra-thin, high-strength high-end foil, and its main customers are LG Energy Solution, Samsung SDI and BYD. With US EV demand soft and a North American customer's plant halted, 2025 revenue fell and losses continued, prompting diversification into ESS and PCB copper foil.

YTD as of 2026-07-10 · source: Yahoo Finance
A materials maker of high-end electrodeposited copper foil for lithium-ion anodes (formerly Iljin Materials), a Lotte Chemical affiliate since its 2023 acquisition. Despite an edge in ultra-thin, high-strength foil, its results are hostage to the EV utilization of cell customers LG Energy Solution, Samsung SDI and BYD; soft US EV demand and a North American customer's plant halt cut 2025 revenue and prolonged losses. In particular, the Samsung SDI-Stellantis JV (StarPlus Energy) — where it was named exclusive foil supplier — entering liquidation talks in February 2026 exposed the downside of its North American exposure. In response it is diversifying into PCB and AI-server-substrate copper foil, while costs are directly exposed to copper prices and the power-intensive electrolytic process — the watch points are a recovery in cell-customer utilization and the pace of the circuit-foil pivot.
