The disclosure provides a battery module. The battery module comprises: a frame having an accommodation space; and a plurality of batteries successively arranged in the accommodation space in a thickness direction of the battery, wherein a partition is arranged between adjacent batteries, wherein the partition has a compressibility and a coefficient of compressibility &#x3b4;at a pressure equal to or smaller than 2 MPa, which meets a relation C&#xd7;&#x3b4;&#x2264;A&#xd7;0.2, wherein Cis an initial thickness of the partition, and Ais an initial thickness of the battery.

Battery module

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.
