摘要： By using a winding type electrode plate assembly resistant to displacement by wind-up and buckling, a lithium ion secondary battery, capable of suppressing deterioration in cycle and storage characteristic caused by expansion and shrinkage of the electrode plate due to charge/discharge cycles or by generation of gas during storage at high temperatures or the like, is accomplished. An electrode plate A comprising a binder mainly composed of a polymer material “a” and an electrode plate B, having the opposite polarity to the electrode plate A, with a porous polymer layer mainly composed of the polymer material “a” or a copolymer of the polymer material “a” formed thereon, are wound up in flat form to give a flat electrode plate assembly, which is soaked in a non-aqueous electrolyte and then heated and cooled, with the soaked state maintained, while pressure is applied in the direction of the thickness of the flat electrode plate assembly, to integrate the electrode plate assembly.

摘要： A lithium ion secondary battery has an electrode group including: a winding core; and a positive electrode and a negative electrode that are wound around the winding core. This electrode group does not have an independent separator between the positive and negative electrodes. A porous film is integrally formed on both sides of at least one of the positive electrode and the negative electrode. The negative electrode and the positive electrode are connected to the winding core by a negative electrode resin film and a positive electrode resin film, respectively. The use of such resin films makes it possible to reduce the breakage of the porous films and prevent a short-circuit between the positive and negative electrodes.
