1. A battery shell for a battery, comprising:
an insulating layer provided at an outer surface of the battery shell, the insulating layer comprising a repair part;
wherein:
the repair part is formed of a curable material and has a shape of a mushroom, the repair part comprising an upper part having a shape of a cover of the mushroom and a lower part having a shape of a stem of the mushroom, the lower part being wholly embedded in the insulating layer, the upper part protruding from the insulating layer, and a lower surface of the upper part covering at least a portion of an upper surface of the insulating layer;
the lower part embedded in the insulating layer does not extend to the outer surface of the battery shell; and
in a cross section of the repair part perpendicular to a surface of the insulating layer, a longest dimension of the upper part is greater than or equal to a sum of a width of the lower part and a creepage distance of the battery.
