Battery and electric device

The utility model is applicable to the technical field of batteries, and provides a battery and a power utilization device, and the battery comprises a battery box body, one or more supporting assemblies and a plurality of battery monomers. The battery box body is provided with an accommodating space. The one or more supporting assemblies are arranged in the accommodating space and are connected with the battery box body, and the accommodating space is divided into at least two placing areas along the height direction by the one or more supporting assemblies; at least one layer of battery monomers is placed in the placement area, and a single layer of battery monomers is formed by arranging a plurality of battery monomers along a first direction and/or a second direction. Wherein the first direction intersects with the second direction and is perpendicular to the height direction of the battery. Thus, the supporting assembly and the battery box form a structural main body which is a stress bearing component, and the supporting assembly is utilized to support the battery monomers in the placement area, so that the stacking height of the battery monomers is guaranteed, the capacitance of the battery is improved, and the use safety of the battery is improved.
