Abstract
An electrolytic copper foil having improved elongation and electrical conductivity is disclosed. The improved elongation and electrical conductivity are due to an increase in shape deformation of grains selective to a specific direction and an increase in an average grain size after heat treatment. An electrode for a secondary battery including the electrolytic copper foil, and a secondary battery including the electrode are disclosed.
