<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a lead storage battery in which an improved vibration resisting property of a lead storage battery when it is used under a load of vibration and a shock and an improved safety counter-measure for preventing a short circuit due to a cathode plate expansion in a life terminal period of the battery can be obtained in a simple process. <P>SOLUTION: In an upper portion of an electrode plate group composed of a cathode plate, an anode plate and a separator, an electrode group fixing member of a single thermoplastic resin is arranged to exist in a lamination direction of the electrode plate group so that an upper portion of the separator higher than the cathode plate and the anode plate can be melted and integrated, and the electrode plates and the electrode plate group can be fixed in a cell. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
