Abstract

A battery and an electric device. The battery (2) comprises a case (202), a battery cell group (7) and a blocking structure (8), wherein the case (202) is provided with an accommodating cavity; and the battery cell group (7) is located in the accommodating cavity, and the battery cell group (7) comprises at least one column of a plurality of battery cells (3) arranged in a first direction, each battery cell (3) comprising a first wall (31) and a second wall (32) connected to and intersecting with each other, the first wall (31)being provided with a pressure relief mechanism, and a gap (203) being provided between the second wall (32) and the case (202). When thermal runaway occurs in the battery, high-temperature ejecta is ejected from the pressure relief mechanism of the first wall (31); and at least part of the blocking structure (8) is located within the gap (203) to prevent at least some of emissions discharged via the pressure relief mechanism from entering the gap (203).
