Abstract

The present application discloses a battery and an electric device. The battery includes: a battery cell (20) provided with a first pressure relief mechanism (21); a housing (10) provided with an inner cavity (11); a first separator plate (30) mounted in the housing (10) to separate the inner cavity (11) into a first chamber (111) and a second chamber (112), where the battery cell (20) is mounted in the first chamber (111), the first separator plate (30) is provided with a through hole (31), the first chamber (111) is communicated with the second chamber (112) through the through hole (31), and the first pressure relief mechanism (21) is communicated with the through hole (31) to allow an ejected substance ejected from the battery cell (20) to flow into the second chamber (112); and a cooling device mounted in the second chamber (112), where the cooling device is configured to cool the ejected substance flowing into the second chamber (112). Application of the technical solution of the present application solves the problems that high-temperature substances ejected during thermal runaway of current batteries not only have the risk of being ignited, but also generate continuous thermal shock and radiation to the periphery of the battery, and great thermal harm is caused.
