Abstract: The present disclosure provides a battery box, which comprises: a lower box body; an upper box body covering the lower box body; a battery module received in the lower box body and the upper box body; and a protecting member positioned above the battery module and covering at least the upper surface of the battery module to prevent high temperature drips formed by accidental combustion of the upper box body above the battery module from dropping onto the battery module. The protecting member of the battery box according to the present disclosure effectively blocks the high temperature drips formed by the accidental combustion of the upper box body of the battery box dropping onto the battery module, and reduces the risk of combustion and explosion of the battery module.

Abstract: Embodiments of the present application provide a case, a secondary battery, a battery pack, a vehicle, and a method for manufacturing a secondary battery. The case includes a bottom wall and a side wall, the bottom wall and the side wall defining an accommodating cavity with an opening at one end for accommodating an electrode assembly of the secondary battery; wherein, an outer surface of the side wall includes a coated region coated with an insulating coating, and the coated region extends, in a height direction of the side wall, from a side of the side wall that is close to the bottom wall to a position near an edge of a side of the side wall that is close to the opening, so as to reserve a non-coated region with a preset height on the outer surface of the side wall that is near an edge of the opening.
