Negative plate and preparation method thereof, battery and electric equipment

The invention discloses a negative plate and a preparation method thereof, a battery and electric equipment. The negative plate comprises a negative electrode material and stabilized lithium powder. The stabilized lithium powder comprises lithium powder and a coating layer, and the surface of the lithium powder is coated with the coating layer. According to the negative plate disclosed by the invention, the stabilized lithium powder is added into the negative plate, and the lithium powder reacts with the hydrogen to generate LiH so as to achieve the purpose of absorbing the hydrogen generated by the positive electrode in the low SOC storage process, so that the hydrogen of the battery is reduced, the expansion of the battery cell is reduced, the safety of the battery is improved, and meanwhile, the increase degree of the interface impedance of the battery cell is reduced; the energy density of the battery is improved and the cycle life of the battery is prolonged.
