The embodiment discloses a cylindrical battery, which comprises a battery shell, a battery core and electrolyte, wherein the battery core is arranged in a shell 1, the electrolyte is filled in the battery shell, and the battery core is soaked.
The battery case includes a case 1, a plurality of ribs 11, a first end cap, and a second end cap. As shown in fig. 1, the case 1 has a cylindrical shape, and the inside thereof accommodates a battery cell and an electrolyte.
The ribs 11 are arranged along the length of the housing 1, i.e. the ribs 11 are arranged parallel to the axis of the housing 1. The plurality of ribs 11 are uniformly arranged on the outer wall of the housing 1 in the circumferential direction of the housing 1. Although the present embodiment is selected to be uniformly distributed along the circumferential direction of the housing 1, this is not a limitation of the present utility model, and the plurality of ribs 11 may be unevenly distributed along the circumferential direction of the housing 1 in other embodiments. The rib 11 is specifically a micro-rib, and a plurality of micro-ribs are provided in the circumferential direction of the housing 1. The micro-ribs have smaller height and width, and can be in a circular arc shape or in a prismatic shape.
The outer side wall of the battery case is provided with a plurality of protruding edges 11 in a ring, when the battery is recovered, the stretching mechanism clamps the battery case, the battery case is not easy to slip in the stretching process, and the shell 1 can be effectively broken.
In addition, the ribs 11 are arranged, so that the whole thickness of the battery case is thicker, and the battery case is not easy to cut off during cutting, thereby ensuring that the battery core is not damaged; further, after the cutting of the ribs 11, the expansion of the battery cells can cause the ribs 11 to spread out, reducing the friction between the battery cells and the case 1, and thus easily separating the battery cells from the case 1.
The first end cover and the second end cover are respectively connected to two ends of the shell 1 and are in sealing connection with the shell 1, and particularly by laser welding. The shell 1 is made of steel, the first end cover and the second end cover are made of steel, and the cylindrical battery is a steel shell battery.
The battery cell comprises a positive plate, a negative plate and a diaphragm, wherein the diaphragms are arranged on two sides of the negative plate. The separator, the negative electrode sheet, the separator and the positive electrode sheet are sequentially laminated and then wound to form the battery cell, and the separator is arranged at the outermost side of the battery cell.
The positive electrode lug of the battery core is led out from the positive electrode plate and is connected to the positive electrode of the cylindrical battery, specifically, the positive electrode lug is welded with the positive electrode, and the positive electrode is arranged on the first end cover. The negative electrode lug of the battery cell is led out from the negative electrode plate and is connected with the negative electrode of the cylindrical battery, specifically, the negative electrode lug is welded with the negative electrode, and the negative electrode is arranged on the second end cover.
The embodiment also discloses a battery recycling device, which comprises a cutting mechanism and a stretching mechanism, wherein the cutting mechanism is used for cutting the battery shell, the cutting depth is smaller than the height of the convex rib 11, specifically, the height of the convex rib 11 is h, and the cutting depth is 0.5h-0.8h. The stretching mechanism is used for clamping two ends of the battery shell and breaking the battery shell. The specific structures of the cutting mechanism and the stretching mechanism are a cutting machine mechanism and a stretching mechanism which are commonly used in the field of battery recovery, and the specific structures are not repeated here. The cutting mechanism is mainly used for controlling the cutting depth of the battery shell so that the strength of the connecting part of the shell 1 is lower and the shell is easy to pull open; and the shell 1 is not completely cut, so that the battery cell is not damaged.
Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments.
