Disclosed are: a positive electrode plate for a lithium ion secondary battery, wherein decrease of the battery capacity over time is suppressed by suppressing deterioration of the electrical conductivity between a positive electrode collector foil and a positive electrode active material layer, separation of the positive electrode active material layer, and the like; a lithium ion secondary battery using the positive electrode plate for a lithium ion secondary battery; a vehicle using the battery; a device with the battery mounted thereon; and a method for producing the positive electrode plate for a lithium ion secondary battery. Specifically disclosed is a positive electrode plate (20) for a lithium ion secondary battery, which comprises a positive electrode collector foil (23) that is formed from aluminum and has porous main surface portions (25A, 25B) which respectively form the main surfaces (23A, 23B), and positive electrode active material layers (21A, 21B) that are respectively formed on the main surface portions of the positive electrode collector foil. The positive electrode plate (20) for a lithium ion secondary battery also comprises coating layers (28A, 28B) respectively between the positive electrode collector foil and the positive electrode active material layers, said coating layers (28A, 28B) directly covering the main surfaces of the positive electrode collector foil and having electrical conductivity and corrosion resistance. |
