Battery-dedicated electrode foil, positive electrode plate, battery, vehicle, and battery-equipped appliance, and manufacture method for the battery-dedicated electrode foil, and manufacture method of the positive electrode plate

A manufacture method for a positive electrode plate that includes a battery-dedicated electrode foil, and a positive electrode active material layer that is supported on a main surface of the battery-dedicated electrode foil, and that contains a positive electrode active material, wherein

• the battery-dedicated electrode foil comprises
• an aluminum electrode foil in which metal aluminum is exposed, or which has on metal aluminum an aluminum oxide layer of 3 nm or less in film thickness;
• and
• a corrosion-resistant layer on a surface of the aluminum electrode foil, and being in direct contact with the metal aluminum of the aluminum electrode foil, or in contact with the aluminum oxide layer, the corrosion-resistant layer being made of a carbide of at least one substance selected from the group consisting of tungsten, tantalum, hafnium, niobium, molybdenum, and vanadium, wherein a thickness of the corrosion-resistant layer is 3 nm to 90 nm, and
• the positive electrode active material layer contains the positive electrode active material that includes a Li compound, and
• the positive electrode active material that includes the Li compound is contained in the main surface of the battery-dedicated electrode foil,
• the manufacture method comprising
• a positive electrode active material layer formation step of forming the positive electrode active material layer by applying and drying a water-based active material paste whose solvent is water.
