Abstract: The disclosure relates to a protection assembly, a cover and a housing. The protection assembly is applied for an energy storage device having a pressure relief element, wherein the pressure relief element is structured to deform in response to an increasing internal pressure in the energy storage device until the pressure relief element bursts, and the energy storage device can expel high temperature particles through the burst pressure relief element. The protection assembly comprises: a particle-blocking layer comprising a receiving side for receiving the high temperature particles and a connecting side opposite to the receiving side, wherein the particle-blocking layer comprises a plurality of particle-blocking units in a concave-convex arrangement, and the particle-blocking unit can block the high temperature particles; and a separate protective layer disposed at the connecting side of the particle-blocking layer and connected to the particle-blocking layer.

Abstract: Provided a battery and an electric apparatus. The battery includes a box, a battery unit, and a protective member. The box includes a first wall. The battery unit is accommodated within the box, where the battery unit is provided with a pressure relief mechanism, and the pressure relief mechanism is configured to form a pressure relief hole for releasing substances inside the battery unit. The protective member is accommodated within the box, where at least a portion of the protective member is located between the first wall and the pressure relief mechanism and configured to cover the pressure relief hole in an axial direction of the pressure relief hole. battery unitIn the embodiments of this application, redundancy designed for the dimension of the protective member can be reduced while thermal protection requirements are met, thereby reducing energy density loss of the battery and improving safety of the battery.
