Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a multi-electrode lithium battery cell and a lithium battery. Background Art

[0002] Multi-pole lithium batteries are composed of multiple groups of cylindrical cells. The multiple groups of cells are combined and connected using a mounting plate, and finally installed inside the lithium battery box.

[0003] When the existing multi-electrode lithium battery cells are assembled, the outer surface is set on a stable frame, which is prone to wear on the outside of the lithium battery;

[0004] The reason for this problem is that during the use of multi-pole lithium battery cells, it is necessary to first place the multi-pole lithium battery cells on the outer surface of the lower mounting plate, then slide the stabilizing frame onto the outer surface of the multi-pole lithium battery cells, and finally install the upper mounting plate above the multi-pole lithium battery cells. The use of the stabilizing frame provides a stabilizing support for the positions of both sides of the lithium battery. Therefore, the stabilizing frame fits closely to the surface of the multi-pole lithium battery cells. At this time, when the stabilizing bracket is sleeved onto the outer surface of the multi-pole lithium battery cells, a certain amount of friction will be generated with the outer surface of the multi-pole lithium battery cells, which may easily cause damage to the outer surface of the multi-pole lithium battery cells during the back-and-forth installation and disassembly process, posing a certain risk to the later use of the multi-pole lithium battery cells. Therefore, we propose a multi-pole lithium battery cell and a lithium battery. Utility Model Content

[0029] By placing the support frame 2 and the connecting frame 201 on the outer surface of the assembled lithium battery cell body 1, the support frame 2 is in contact with the end position of the connecting frame 201, and then pushing the pushing block 205 to make the sliding plate 202 slide inside the sliding groove 207 and the limiting groove 206, sliding the two groups of sliding blocks 204, so that the sliding block 204 squeezes the spring 208, and moves the end of the sliding plate 202 to the middle position of the two groups of clamping blocks 203. At this time, let go of the sliding block 204, push the clamping block 203 under the tension of the spring 208, and insert the clamping block 203 into the interior of the sliding plate 202.

[0030] A sliding groove 207 is provided on the outer surface of the support frame 2, and the sliding plate 202 is slidably connected to the inside of the sliding groove 207.
