The invention provides a battery pole piece, the battery pole piece comprises a current collector, an active material layer and an insulating layer, the active material layer and the insulating layer are arranged on the current collector, the area, not provided with the active material layer and the insulating layer, of the current collector is an empty foil area, the active material layer is arranged on at least one surface of the current collector, and the insulating layer is arranged on the surface of the current collector. The insulating layer is adjacent to the active material layer, the insulating layer is positioned between the active material layer and the empty foil region, and the insulating layer comprises solid insulating particles with a lithium ion conduction function. According to the technical scheme, the capacity of the active substance layer can be fully exerted, and the insulating layer reduces the influence on the specific capacity of the battery while ensuring the safety of the battery. The invention also provides a battery comprising the electrode plate, and an electric vehicle and an energy storage device comprising the battery.
