Current collector plate, battery, and electric device
By setting a weak explosion-proof structure between the connection parts of the current collector, the problem of the battery requiring a large internal pressure to open the valve is solved, and the valve can be opened more easily under a preset pressure, thus improving the safety performance of the battery.

Abstract
The application discloses a current collecting plate, a battery and an electric device, and belongs to the technical field of batteries. The current collecting plate comprises a first connecting part, a second connecting part and an explosion-proof structure. The second connecting part is connected to the outer peripheral side of the first connecting part. The first connecting part is used for being connected with a bottom shell of the battery. The side, which is away from the bottom shell of the battery, of the second connecting part is used for being connected with a winding core. The explosion-proof structure is arranged between the second connecting part and the first connecting part. The thickness of at least part of the explosion-proof structure is smaller than the thickness of the second connecting part and / or the first connecting part. The resistance when opening the valve can be reduced, the pressure value when the battery opens the valve is reduced, the safety redundancy is improved, and the valve opening is facilitated.
