<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode body and a manufacturing method of a battery capable of alleviating variations in thicknesses in an outer-diameter direction or a thickness direction. <P>SOLUTION: Electrode wound-around bodies 100 are classified in accordance with a film-thickness slanting angle θP of a cathode and a film-thickness slanting angle θN of an anode, and a combination of the cathode and the anode to be wound around is decided for each classification. A thick-film portion of a cathode and a thin-film portion of an anode are superposed while a thin-film portion of a cathode and a thick-film portion of an anode are superposed on one another, whereby, a total thickness of a laminated body with the cathode, the anode, and a separator laminated is balanced from one place of the laminated body to the other. Furthermore, the same procedure is applied to an electrode laminated body which is not wound around. <P>COPYRIGHT: (C)2010,JPO&INPIT |
