<p>A method for manufacturing, with good productivity, a lithium ion secondary battery which is light-weight and can maintain the safety without using a strong outer-packaging can and which has a low internal resistance and is practical. The lithium ion secondary battery is provided with a flat wound-type multilayer electrode body which is made by locating a belt-like positive pole (3) with a positive active material layer (7) and a positive collector (6) and a belt-like negative pole (5) with a negative active material layer (9) and a negative collector (10) alternately between turns of a wound belt-like separator (4) having an electrolytic solution including lithium ions and then adhering pairs of the positive pole (3) or the negative pole (5) and the separator (4) with adhesive layers (11).</p> |
