The present application relates to the technical field of batteries, and discloses a single battery, comprising battery cells, a top cover, and connection members. Tabs extend out from one end of each battery cell; the top cover comprises conductive terminals; the connection members each comprise a base body and a thinned region, and the thickness of the thinned region is smaller than that of the base body; the conductive terminals are welded to the thinned regions; and the tabs are welded to the base bodies. The connection members are connected to the conductive terminals by means of the thinned regions, and are connected to the tabs by means of the base bodies. The thickness of the base bodies does not affect the welding between the thinned regions and the conductive terminals. Therefore, the structure and thickness of the thinned regions can be rationally configured according to welding requirements. The thickness of the base bodies is rationally configured according to current passing requirements, thereby avoiding the effect of the increase in the current passing area of the connection members on the yield of welding between the connection members and the conductive terminals. In addition, the thinned regions realize the reduction of local thickness, thereby reducing the amount of a material, facilitating the reduction of the material cost, reducing the weight, facilitating the improvement of the weight energy density of single batteries, and implementing high-energy-den

Disclosed is a hot-pressing apparatus, which comprises a hot-pressing drive mechanism, a first hot-pressing mechanism, a second hot-pressing mechanism, a diaphragm clamping mechanism and a jacking mechanism. Before transferring the battery cell, the supporting assembly may be driven first to jack a part of the diaphragm, thus forming the transferring-supporting surface above the second hot-pressing plate. The jaw first places the battery cell on the transferring-supporting surface, the transferring-supporting surface may contact only a part of the battery cell to allow the jaw to be suspended, and once the jaw is released, it can be withdrawn. Next, the jacking mechanism withdraws to flatten the diaphragm, and the battery cell will be borne on the diaphragm steadily. As the hot-pressing drive mechanism drives the first hot-pressing plate and the second hot-pressing plate close to each other, the first hot-pressing plate may press the diaphragm and the battery cell borne on the diaphragm against the second hot-pressing plate. It is clear that in a process of transferring the battery cell to the second hot-pressing plate, the use of the diaphragm for transferring may prevent the battery cell from shaking or tilting, thus placing the battery cell steadily.
