摘要： PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery satisfying both long service life and high output. SOLUTION: The lithium ion secondary battery has an electrode occluding and emitting lithium ions, and a separator laminated on each other. The electrode has an electrode-mixture coated layer formed by coating an electrode mixture obtained by dispersing and kneading an active material and conductive fibers on the separator, and a wire interposed between the electrode-mixture coated layer and the separator to be electrically connected to the electrode-mixture coated layer. This structure increases a current collecting efficiency without using a collector, and enhances adhesion between the electrode-mixture coated layer and the separator to prevent the electrode-mixture coated layer from being peeled from the separator.
