Description

Technical Field

[0002] A ternary polymer lithium battery refers to a lithium battery whose positive electrode material uses lithium nickel cobalt manganese or nickel cobalt aluminum oxide as a ternary positive electrode material. The positive electrode, negative electrode and separator are wound inside the cylindrical metal shell of the ternary lithium battery. A layer of insulating separator is wound around the outside of the positive electrode core, and a layer of separator is also wound between the positive and negative electrode cores.

[0003] When recycling existing cylindrical ternary lithium batteries, the used batteries are generally crushed first, and then the metal materials in the crushed batteries are dissolved and extracted. However, the crushed batteries require a large amount of chemical solvents to dissolve, and multiple filtering and screening processes are still required afterwards, which makes the battery recycling cost high. The retired cylindrical ternary lithium batteries used in current electric vehicles are all of the same specifications, which makes large-scale recycling of single batteries more feasible and facilitates reducing recycling costs. In addition, the positive electrode core of the cylindrical ternary lithium is precious metals such as lithium, nickel and cobalt, which are also the main recycling materials of the battery. However, after the positive electrode core is used many times, part of the core material will be contaminated on the inner and outer winding diaphragms, which reduces the material recovery rate.

[0021] Example 2, reference Figure 1-Figure 9 The top of the placing table 2 is connected to a plurality of mutually symmetrical hydraulic columns 11, the side walls of the hydraulic columns 11 are connected to a plurality of electric control slide rails 13 through a cross bar 12, and the inner side walls of the electric control slide rails 13 are provided with a shell breaking assembly for opening the shell of the standard battery 3; Furthermore, the shell breaking assembly is composed of a cutting disc 15 and a shell opening electric push rod 17.

It should be noted that: after the standard battery 3 is limited and discharged, the control slider 14 is first allowed to slide on the inner wall of the electric control slide rail 13 to one side of the discharge limit plate 5, and then the control motor on the control slider 14 is used to drive the cutting disc 15 to rotate, and the electric control slide rail 13 is driven to move slowly downward through the hydraulic column 11, so that the rotating cutting disc 15 can cut the shell of the standard battery 3. During cutting, the control slider 14 moves on the electric control slide rail 13 toward one side of the discharge positioning plate 10, so that the discharge positioning plate 10 offsets the horizontal force generated by the cutting. After the cutting is completed, the shell opening electric push rod 17 will be slowly pushed downward , push the output end of the shell opening electric push rod 17 down to squeeze the winding core and push it into the gap just cut by the standard battery 3, then let the shell supporting column 18 and the shell breaking cone 19 in the storage grooves on both sides of the shell opening electric push rod 17 rotate out, open the gap after the standard battery 3 is cut, and let the shell breaking cone 19 be inserted into the shell of the standard battery 3, then lift the shell opening electric push rod 17 upward, then one side of the shell of the standard battery 3 after cutting will be subjected to an upward pulling force, and the two ends of the standard battery 3 are limited by the cutting ring 9, and its shell will rotate along the cutting ring 9 at both ends, and the shell in the middle is pulled up to unfold and detach, so as to separate the shell of the standard battery 3; A further advantage of adopting the above method is that the metal shell of the standard battery 3 can be separated relatively completely, which is convenient for the subsequent recycling of the metal material. Compared with the crushing process, the waste of screening resources is avoided.

[0022] Example 3, reference Figure 1-Figure 9 The bottom of the placing table 2 is connected to two heating conveying rollers 23 through a gear assembly, the top of the processing table 1 is connected to a recovery tank 29, a plurality of winding rollers 27 are arranged on the top of the recovery tank 29, and a scraping brush 28 for cleaning the diaphragm is arranged below two adjacent winding rollers 27; Further, the gear assembly is composed of a main gear 21 and a sub-gear 22, the main gear 21 meshes with the sub-gear 22, a plurality of conveying motors 20 are fixedly connected to the bottom end of the placement table 2, the output end of the conveying motor 20 is fixedly connected to the inner wall of the main gear 21 through a conveying shaft, a through hole is opened at the bottom of the placement groove on the placement table 2, the through hole is located directly above two adjacent heated conveying rollers 23, the inner walls of the main gear 21 and the sub-gear 22 are respectively fixedly connected to two adjacent heated conveying rollers 23 through two conveying shafts, the top of the processing table 1 is fixedly connected to the bottom end of the recovery groove 29, a plurality of winding motors 24 are fixedly connected to the top of the recovery groove 29, the output end of the winding motor 24 is fixedly connected to two winding rollers 27 through a winding main tooth 25 and a winding sub-tooth 26, the two winding rollers 27 are located below the two adjacent heated conveying rollers 23, and a scraper 28 is arranged below the two winding rollers 27; It should be noted that: after the metal shell of the standard battery 3 is separated, the positive electrode core and the negative electrode core of the standard battery 3 are separated by using the metal material at both ends of the battery, and the wound diaphragm will pass through the perforation in the placement groove of the placement table 2 and enter between the two heated conveying rollers 23 below. The conveying motor 20 is started to drive the main gear 21 to rotate, and the main gear 21 will drive the meshing sub-gear 22 to rotate in the opposite direction, thereby driving the heated conveying roller 23 to rotate inward in the opposite direction, continuously pressing the diaphragm downward, and heating the diaphragm during the pressing process. The diaphragm made of polymer material is easily stretched and expanded after heating. The barbs on the two winding rollers 27 below will grab and reel the diaphragm, and the winding motor 24 drives the main winding teeth 25 and the auxiliary winding teeth 26 to rotate in opposite directions, so that the two diaphragms in contact with the positive electrode material are unfolded downward, and the winding speed of the winding roller 27 is slightly greater than the speed at which the heating conveying roller 23 is pressed downward, so that the diaphragm is partially stretched, and the expansion and stretching of the diaphragm reduces the adhesion of the positive electrode material on its surface. At this time, the control system is used to drive the scraper 28 to rotate, brush the stretched diaphragm surface, and brush the positive electrode material attached to the diaphragm surface into the recovery tank 29; A further benefit of adopting the above method is that it can collect the rare positive electrode materials attached to the diaphragm inside the cylindrical battery roll core, making the battery recycling more profitable and avoiding the production costs of using large-scale chemical solvents and subsequent screening processes.

[0023] When the present invention is in use, the retired and waste standard batteries 3 are sequentially placed in the multiple placement grooves of the placement table 2, so that one end of the standard battery 3 is in conflict with the discharge positioning plate 10, and the standard battery 3 is limited by the compression of the cutting rings 9 at the front and rear ends, and then the limiting ring 7 on the adjustment shaft 4 is rotated out from the limiting concave plate 8, so that the rotation of the adjustment shaft 4 is released from the limit, and the adjustment shaft 4 will drive the multiple discharge limiting plates 5 to flip under the action of the torsion spring 6, so that the discharge limiting plates 5 are in conflict with the other end of the standard battery 3, and the standard battery 3 is discharged, so as to avoid the safety hazard of the residual electricity in the standard battery 3 in the subsequent cutting process, so as to ensure the safety of battery material recycling, and the battery is positioned and limited, which is convenient for the subsequent cutting and removal of the battery shell, and improves the recycling processing efficiency; After the standard battery 3 is limited and discharged, the control slider 14 is first allowed to slide on the inner wall of the electric control slide rail 13 to one side of the discharge limit plate 5, and then the control motor on the control slider 14 is used to drive the cutting disc 15 to rotate, and the electric control slide rail 13 is driven to slowly move downward by the hydraulic column 11, so that the rotating cutting disc 15 can cut the shell of the standard battery 3. During cutting, the control slider 14 moves on the electric control slide rail 13 toward one side of the discharge positioning plate 10, so that the discharge positioning plate 10 offsets the horizontal force generated by the cutting. After the cutting is completed, the shell opening electric push rod 17 will be slowly pushed downward, and the output end of the shell opening electric push rod 17 will be pushed down to squeeze the reel core and push it into the shell after the standard battery 3 has just been cut. The shell support column 18 and the shell breaking cone 19 in the receiving grooves on both sides of the shell opening electric push rod 17 are then rotated out to open the gap after the standard battery 3 is cut, and the shell breaking cone 19 is inserted into the shell of the standard battery 3, and then the shell opening electric push rod 17 is lifted upward, so that one side of the shell of the standard battery 3 after cutting will be subjected to an upward pulling force, and the two ends of the standard battery 3 are limited by the cutting ring 9, and the shell of the standard battery 3 will rotate along the cutting ring 9 at both ends, and the shell in the middle is pulled up and disengaged, so as to realize the separation of the shell of the standard battery 3, so that the metal shell of the standard battery 3 can be separated relatively completely, which is convenient for the subsequent recycling of the metal material, and compared with the crushing process, it avoids the waste of screening resources; After the metal shell of the standard battery 3 is separated, the positive electrode core and the negative electrode core of the standard battery 3 are separated by using the metal material at both ends of the battery, and the wound diaphragm will pass through the perforation in the placement groove of the placement table 2 and enter between the two heated conveying rollers 23 below. The conveying motor 20 is started to drive the main gear 21 to rotate, and the main gear 21 will drive the meshing sub-gear 22 to rotate in the opposite direction, thereby driving the heated conveying roller 23 to rotate inward in the opposite direction, continuously pressing the diaphragm downward, and heating the diaphragm during the pressing process. The diaphragm made of polymer material is easily stretched and expanded after heating, and the barbs on the two winding rollers 27 below will grab and wind up the diaphragm, and the winding motor 24 drives the winding main gear 21 to rotate. The teeth 25 and the winding auxiliary teeth 26 rotate in opposite directions, so that the two diaphragms in contact with the positive electrode material are unfolded downward. The winding speed of the winding roller 27 is slightly greater than the speed at which the heated conveying roller 23 is pressed downward, so that the diaphragm is partially stretched. The expansion and stretching of the diaphragm reduces the adhesion of the positive electrode material on its surface. At this time, the control system drives the scraper 28 to rotate to brush the stretched diaphragm surface, and brush the positive electrode material contaminated and attached to the diaphragm surface into the recovery tank 29. In this way, the positive electrode rare material attached to the diaphragm in the cylindrical battery roll core can be collected, so that the battery recycling benefits are greater and the production cost of using large-scale chemical solvents and subsequent screening processes is avoided.
