<P>PROBLEM TO BE SOLVED: To provide a secondary battery in which injecting time of an electrolytic liquid can be shortened and the electrolytic liquid can be penetrated uniformly in the manufacturing process of a secondary battery, and the secondary battery in which lamination shifting hardly occurs in a lamination process and the later process of a positive electrode, a negative electrode, and a separator. <P>SOLUTION: The non-aqueous electrolytic liquid secondary battery has a plurality of positive electrode plates and negative electrode plates laminated so as to be opposed through a separator composed of a porous resin film. The separator is installed so that the positive electrode plate is sealed in it, and the positive electrode plate is formed so that its length in short-length direction may be shorter than the length of the negative electrode plate in short-length direction so that it may form a part of an injection passage at the time of injecting the non-aqueous electrolytic liquid, at the end part with the opposed negative electrode plate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
