Battery and electric equipment

The utility model relates to electric equipment, a battery comprises a plurality of battery monomers and a buffer assembly, the plurality of battery monomers are arranged along a first direction to form a battery monomer group, the buffer assembly comprises a first buffer piece and a second buffer piece, and the second buffer piece is deviated from the battery monomer group on one side of the first direction. The second buffer piece is in contact with at least one battery monomer on the other side of the first direction; the two sides of the first buffer piece in the first direction are in contact with different battery monomers respectively, and the first direction is the thickness direction of the first buffer piece and the second buffer piece; the rigidity of the first buffering piece in the first direction is smaller than that of the second buffering piece in the first direction. The electric equipment comprises the battery. According to the battery and the electric equipment, the first buffer piece can better relieve expansion of the battery monomers compared with the second buffer piece, and the buffer assembly can meet different expansion relieving requirements of the battery monomers in the same battery monomer group at the same time.
