Abstract
An electrode plate of a rechargeable battery that is capable of preventing wastage of a base film and preventing an active material layer from being irregularly formed and a method for fabricating the same is disclosed. The electrode plate is fabricated by continuously coating the active material layer lengthwise along a surface of the base film and cutting the base film in a direction substantially perpendicular to a length of the base film or in a direction that forms a predetermined angle in relation to the length of the base film. The method includes forming an active material layer lengthwise on a base film except for on predetermined parts of both ends of the base film by continuously coating active materials, and forming an electrode plate by cutting the base film formed with the active material layer in a direction substantially perpendicular to the length of the base film using a cutter.
