Secondary Battery

LOTTE Aluminium develops cathode foil products for secondary batteries and supplies them to leading secondary battery companies in Korea and overseas.
Cathode Foil
Cathode foil is a critical material used in the first stage of secondary battery manufacturing, and it is an essential component that determines the capacity and voltage of secondary batteries. With the rapid growth in global demand for secondary batteries—driven by electric vehicles, energy storage systems, and small batteries—we are actively expanding our production bases to establish a global manufacturing infrastructure.

Processability

Cathode Foil
As the most critical core material for secondary battery development, we supply advanced quality products such as ultra-thin and ultra-high strength foils.

Coated Foil
A material where conductive substances such as carbon are coated on cathode foil, preventing detachment of cathode active materials, reducing electrical resistance, and enhancing battery performance.

Pouch cell for Battery
With excellent processability for manufacturing high energy density battery cells, strong sealing power provides outstanding weather resistance, ensuring stability until the end of its lifespan — a product integrating advanced technology.
