Abstract

The present application provides a case (10), a battery (100), and an electric device. A bottom plate (101) of the case (10) comprises a composite plate (1011) and a heat exchange plate (1012); the composite plate (1011) comprises a first material portion (10111) formed of a first material and a second material portion (10112) formed of a second material; a first welding surface (1011a) is formed on a part of the surface of the composite plate (1011); the first welding surface (1011a) is formed of the first material portion (10111); a second welding surface (1012a) is formed on a part of the surface of the heat exchange plate (1012); the heat exchange plate (1012) at the second welding surface (1012a) is formed of a third material; the third material and the first material are the same material; and the first welding surface (1011a) is welded to the second welding surface (1012a). According to the case (10) provided in the embodiments of the present application, an aluminum plate is replaced with the composite plate (1011), such that the problem of the quality of the case (10) being affected due to the heat exchange plate (1012) being difficult to weld can be effectively mitigated.
