The present application provides a negative electrode plate, a preparation method therefor, a secondary battery and a power consuming device. The method comprises: providing a negative electrode current collector; coating at least one surface of the negative electrode current collector with a photosensitive adhesive and curing same to form a photosensitive layer; patterning light into a preset pattern, and allowing the incidence of the light from the surface of the photosensitive layer that is away from the negative electrode current collector to the photosensitive layer to expose the photosensitive layer; developing the exposed photosensitive layer to obtain a photosensitive layer having a recessed portion; filling the recessed portion with a negative electrode slurry, and curing the negative electrode slurry to form a negative electrode film layer; and removing at least a part of the photosensitive layer to obtain the negative electrode plate.
A method for preparing a negative electrode plate, comprising:
A secondary battery, comprising a negative electrode plate which is prepared with operations comprising:
A power consuming device, comprising a secondary battery, wherein the secondary battery comprising a negative electrode plate which is prepared with operations comprising:
