As shown in fig. 2, 4, 5 and 6, the thickness of the first clamping jaw 110 is h1, the depth of the first accommodating groove 211 is h2, and h1 is h 2; the thickness of the second jaw 120 is h3, which is equal to the depth of the second receiving groove 221, h4, h3 is h 4. Therefore, after the first clamping jaw 110 is accommodated in the first accommodating groove 211 of the first hot press plate 210 and the second clamping jaw 120 is accommodated in the second accommodating groove 221 of the second hot press plate 220, the lower surface of the first hot press plate 210 can be flush with the lower surface of the first clamping jaw 110, and the upper surface of the second hot press plate 220 can be flush with the upper surface of the second clamping jaw 120, so that it is ensured that all areas between the first large surface portion 310 and the second large surface portion 320 of the battery cell 300 can be uniformly hot-pressed in the hot pressing process.
In addition, as shown in fig. 1, the battery cell 300 is a laminated battery cell 300, the battery cell 300 is rectangular-like, and includes a first large surface portion 310, a second large surface portion 320, a first side surface portion 330, a second side surface portion 340, a top portion 350, and a bottom portion 360, the first large surface portion 310 is disposed opposite to the second large surface portion 320, the first side surface portion 330 is disposed opposite to the second side surface portion 340, the top portion 350 is disposed opposite to the bottom portion 360, an area of the first large surface portion 310 or the second large surface portion 320 is greater than an area of the first side surface portion 330, the second side surface portion 340, the top portion 350, or the bottom portion 360, the first clamping jaw 110 is clamped on the first large surface portion 310, and the second clamping jaw 120 is clamped on the second large surface portion 320. It should be noted that, the present invention does not limit the forming manner of the battery cell 300, and in other embodiments, the battery cell 300 may also be a winding battery cell 300. In addition, as shown in fig. 1, the positive tab 370 and the negative tab 380 of the battery cell 300 are both attached to the top 350 of the battery cell 300.

In addition, as shown in fig. 6, after the first clamping jaw 110 is accommodated in the first accommodating groove 211 of the first hot press plate 210 and the second clamping jaw 120 is accommodated in the second accommodating groove 221 of the second hot press plate 220, the gap between the first clamping jaw 110 and the groove wall of the first accommodating groove 211 is D1; the gap between the second clamping jaw 120 and the groove wall of the second receiving groove 221 has a dimension D2. When the gap D1 between the first clamping jaw 110 and the groove wall of the first receiving groove 211 or the gap D2 between the second clamping jaw 120 and the groove wall of the second receiving groove 221 is too small, the difficulty in matching between the first clamping jaw 110 and the first receiving groove 211 and the difficulty in matching between the second clamping jaw 120 and the second receiving groove 221 are both high, the first clamping jaw 110 is difficult to be accommodated in the first receiving groove 211 of the first hot pressing plate 210, and the second clamping jaw 120 is difficult to be accommodated in the second receiving groove 221 of the second hot pressing plate 220. When the gap D1 between the first clamping jaw 110 and the groove wall of the first receiving groove 211 or the gap D2 between the second clamping jaw 120 and the groove wall of the second receiving groove 221 is too large, the region of the first large surface portion 310 corresponding to the gap D1 and the region of the second large surface portion 320 corresponding to the gap D2 cannot be uniformly hot-pressed, so that the performance of the whole battery cell 300 is affected. In one embodiment, 0.05mm D1 is 1mm, and 0.05mm D2 is 1mm, so as to avoid the above problems. In addition, because D1 is not less than 1mm and D2 is not less than 1mm, the area of the first large surface portion 310 of the battery cell 300 corresponding to the gap D1 is smaller than the area of the first large surface portion 320 as a whole, and the area of the second large surface portion 320 of the battery cell 300 corresponding to the gap D2 is smaller than the area of the second large surface portion 320 as a whole, so the existence of the gap D1 and the gap D2 does not affect the overall uniformity of the pressure distribution when the battery cell 300 is hot-pressed.
