Battery, electric device, method for manufacturing battery, and device for manufacturing battery

A battery, comprising:

• a plurality of battery cells, wherein a wall with a largest area among outer walls of each of the battery cells is provided in parallel to a horizontal plane;
• and
• a binding component, configured to accommodate and bind the plurality of battery cells, wherein a reinforcing portion is provided at a part of the binding component parallel to the wall with the largest area, and the reinforcing portion is configured to reinforce a strength of the binding component so as to enhance a binding force of the binding component to walls with the largest area among outer walls of the plurality of battery cells,
• wherein the binding component comprises:
• an upper cover, wherein at least a part of the upper cover is provided at a top of the plurality of battery cells;
• and a lower case, wherein at least a part of the lower case is provided at a bottom of the plurality of battery cells,
• wherein the reinforcing portion is provided at a part of the upper cover provided at the top of the plurality of battery cells, and/or a part of the lower case provided at the bottom of the plurality of battery cells, and
• wherein the binding component protrudes in a direction away from the battery cells to form the reinforcing portion, and a recess is formed on a surface of the binding component close to the battery cells in a region opposite to the reinforcing portion.
