Battery, power consumption device, and method and device for producing battery

A method for producing a battery, comprising:

• providing a plurality of battery cells arranged along a first direction;
• providing a thermal management component extending along the first direction and being connected to a first wall of each battery cell among the plurality of battery cells, the first wall being a wall with a largest surface area of the battery cell, the thermal management component being configured to adjust a temperature of the battery cell;
• and
• wherein in a second direction, a size H1 of the thermal management component and a size H2 of the first wall satisfy:
• 0.1≤H1/H2≤2, and the second direction is perpendicular to the first direction and parallel to the first wall;
• wherein the thermal management component comprises a first thermally conductive plate and a second thermally conductive plate provided opposite to each other along a third direction;
• and
• wherein, a flow channel is provided between the first thermally conductive plate and the second thermally conductive plate, and the flow channel is configured to accommodate a fluid for adjusting a temperature of the battery cell, and the third direction is perpendicular to the first direction and the second direction.
