Abstract
Disclosed herein is an electrode assembly for secondary batteries, wherein the electrode assembly is constructed in a structure in which 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, are bent in a zigzag fashion in vertical section, and the cathode and the anode are fitted to each other, such that the electrode active material layers face each other, while a separator is disposed between the cathode and the anode. The electrode assembly according to the present invention has the effect of simplifying a process for manufacturing a battery, thereby reducing the manufacturing costs and the manufacturing time, and therefore, improving the productivity.
