Abstract:
1. A process for manufacturing an electrode assembly, comprising: prior to assembly of the electrode assembly, bending a cathode, having an active material layer coated on one major surface of a current collector, and an anode, having an active material layer coated on one major surface of another current collector, in a zigzag fashion in vertical sections; and after the bending of the cathode and the anode, fitting the cathode and the anode to each other, such that the electrode active material layers face each other, while a separator is disposed between the cathode and the anode, wherein the separator extends longer than the length of each electrode measured in a widthwise direction perpendicular to a bending direction, and the extension of the separator covers outer surfaces of the fitted electrodes.
