    摘要： A power storage device (1) is provided with a case (10) and an electrode body (50) housed in the case (10). The case (10) includes a bottomed prismatic shaped case body (21) with an opening (21c), and a plate-shaped lid member (31) closing the opening (21c). The case body (21) includes an opening peripheral portion (21f) that is bent to the inside (GH1) of the opening (21c) over the entire circumference. The lid member (31) includes a lid peripheral portion (31f) that is bent toward an inner surface (31n) over the entire circumference. While the lid peripheral portion (31f) is stacked, over a ring-band shaped range (SR), on the opening peripheral portion (21f) on the outside (IH1) in the thickness direction, the lid peripheral portion(31f) and the opening peripheral portion (21f) are hermetically joined to each other.

    摘要： A power storage device (1) includes a rectangular box-shaped case (10) and an electrode body (50) housed therein. An opening peripheral portion (21f) of a case body (21) of the case (10) is bent to the inside (GH1) of the opening (21c). A lid peripheral portion (31f) of the lid member (31) is bent on an inner surface (31n) side. The lid peripheral portion (31f) and the opening peripheral portion (21f) are hermetically jointed together while the lid peripheral portion (31f) stacked on the opening peripheral portion (21f) on the outside (IH1) in its thickness direction over a ring-band shaped range (SR). An electrode laminated portion (50e) of the electrode body (50) is elastically compressed in an electrode-body thickness direction (FH) by a first main wall portion (11) and a second main wall portion (12) of the case (10) having the elasticity.

    摘要： An energy-storage apparatus and an electricity-consumption device are disclosed in the present disclosure. The energy-storage apparatus includes a housing having an opening, an electrode assembly, an end cover assembly sealing the opening, and a first connector. The housing defines an accommodating cavity. The end cover assembly includes a top cover and a lower plastic assembly. The lower plastic assembly is disposed between the top cover and the electrode assembly. The lower plastic assembly is located between the top cover and the first connector. The top cover includes a first stimulus-response member. The lower plastic assembly includes a first-lower-plastic-member body, a first recess, and a first vent hole. The first-lower-plastic-member body has a first surface and a second bottom surface. The first recess is recessed from the second surface to the first surface. The first vent hole is defined in a recess bottom-wall of the first recess and penetrates through the recess bottom-wall and the first surface. The first vent hole is opposite to the first stimulus-response member in a thickness direction of the end cover assembly. The first connector is connected between the end cover assembly and the electrode assembly. A part of the first recess is blocked by the first connector, and the rest of the first recess exposed beyond the first connector forms a vent passage. The vent passage is in communication with the first vent hole.
