摘要： A battery pack and a vehicle is provided. The battery pack includes a first partition piece (31), a battery row (41), and a shielding member (43). The first partition piece (31) is located between two batteries (411) adjacent to each other in a first direction (W) in the battery row (41). An upper surface of the first partition piece (31) is lower than an upper surface of a top cover (411a). A recess (S) is formed between the battery row (41) and the first partition piece (31). The shielding member (43) includes a first shielding portion (431) and a second shielding portion (432). The first shielding portion (431) overlays all explosion-proof valves (411b) of the battery row (41). A passage (P) is disposed between the first shielding portion (431) and the upper surface of the battery row (41). The passage (P) is configured to guide a fluid to flow along the first direction (W) and is provided with a downward opening (O). The second shielding portion (432) closes off a part of the opening (O) facing the recess (S) directly. By setting the second shielding portion (432) to closes off a part of the opening (O), the part facing the recess (S) directly. A fluid generated by thermal runaway can be effectively prevented from flowing into the recess (S), more reliably achieves directional expulsion of the thermal runaway fluid, and enhances safety performance of the battery pack.

摘要： This application provides an accommodating apparatus, a battery, an electric device, and a manufacturing device and method of battery, and relates to the field of battery technologies. The accommodating apparatus includes a first box, a second box, and a sealing assembly, where the first box has an open end; the second box is configured to cover the open end; and the sealing assembly includes a first sealing piece and a second sealing piece that are separate from each other. The first sealing piece and the second sealing piece are configured to abut against the open end and the second box respectively, so as to implement a hermetic connection between the first box and the second box. The first sealing piece and the second sealing piece are separate from each other, so that the first sealing piece and the second sealing piece can be installed separately without interference. This makes the installation of the first sealing piece and the second sealing piece more flexible, allowing them to be installed between the first box and the second box in a proper manner, so as to properly utilize the space between the first box and the second box. This is conducive to reducing outline dimensions of the accommodating apparatus, thereby increasing volumetric energy density of the battery using such accommodating apparatus.
