Abstract: This application discloses a negative electrode plate, and a method for preparing same, and related devices. The negative electrode plate includes a current collector. The current collector is made of a foamed metal material. The current collector includes a first region, a second region, and a third region arranged sequentially along a first direction. An interior of the first region is provided with a negative active material. The second region is filled with an insulation material. The third region is provided with no negative active material. The technical solution hereof ensures that no metal particles are deposited in a tab region in a battery that uses foamed metal as a negative electrode, thereby avoiding a short circuit of a battery cell caused by dendrites arising from surplus metal particles deposited in the tab region, and in turn, enhancing safety performance of the battery.
