Battery device, electric device, and cushion

Abstract

The application discloses a battery device, a power utilization device and a buffer pad, relates to the technical field of batteries, and the battery device comprises a battery monomer and a buffer pad. The buffer pad is arranged on one side of the battery monomer in a first direction, and the buffer pad comprises a first layer and a second layer which are arranged in a laminated mode along the first direction. The first layer is provided with a first cavity, the first cavity is filled with a first fluid, the second layer is provided with a second cavity, the second cavity is filled with a second fluid, the first fluid is compressible, and the second fluid is incompressible. According to the buffer pad, the battery monomer can be well buffered, uniformly pressed, stably supported and separated, so that the buffer pad can stably and reliably buffer, support and separate the battery monomer under high pressure, the probability of deformation of the battery monomer due to the failure of buffering, supporting and separating of the buffer pad is reduced, the battery monomer can stably and reliably operate, and the operation stability of the battery device is better.
