Abstract
The present invention relates to a method for manufacturing an anode of a lithium-ion battery capable of controlling an expansion directionality of an anode material whose volume expands by charging, and a lithium-ion battery including the anode manufactured by the method. More specifically, the present invention provides a method capable of improving the life of a lithium-ion battery by adjusting the tensile strength of a current collector and thus controlling the expansion directionality of an anode material, which expands during charging.
