Problems solved by technology

However, in the existing process, the battery core is not subject to external force, and it takes a long time to age, which reduces the production efficiency
And even if the aging time is prolonged, the gas in the battery cannot be completely discharged into the air bag, which reduces the production quality of the battery

Embodiment 1

[0018] Embodiment 1: as figure 1 As shown, a polymer cell aging fixture includes several vertically arranged splints 3 for supporting the cell 7 and the air bag 8, and the corners of the splints are pierced with support shafts 5, and between two adjacent splints A return spring 6 is arranged between them, and the return spring is sleeved on the support shaft. A pressing plate 2 is arranged on the upper end of the uppermost splint, a positioning plate 1 is arranged above the pressing plate, and a positioning shaft 4 runs through the middle of the positioning plate. The positioning plate is threadedly connected, and the lower end of the positioning shaft is rotatably connected with the pressing plate.

[0019] An aging process of a polymer cell aging jig as described above, the steps are as follows: 1) Put the cells to be aged on the plywood in a regular, orderly and layered manner, press down and rotate the positioning shaft, because the positioning shaft Threaded connection w...

Embodiment 2

[0021] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as figure 2 , 3 As shown, both the splint and the pressure plate are provided with a scraper mechanism for applying pressure to the surface of the cell near the support shaft. The supporting shaft is a screw rod, and the scraper mechanism includes a driving gear 9 located inside the splint or pressing plate. A drive shaft 12 is fixedly connected, and a scraper is arranged on the drive shaft. The upper and lower ends of the driving gear and the driven gear are provided with rotating bearings 11 . The scraper is connected eccentrically to the drive shaft. The axis of the drive shaft is provided with a sliding hole 13, and a sliding shaft 14 is slidably connected in the sliding hole, and the scraper 16 is sleeved on the sliding shaft. .

[0022] Both the splint and the pressure plate are equipped with a scraper mechanism for applying pressure on the s...

Abstract

The invention relates to a lithium battery aging technology, in particular to a polymer cell aging fixture and an aging process using the fixture. Polymer cell aging fixture, including several splints arranged vertically to support the cell and the air bag, the support shafts run through the corners of the splints, and a return spring is arranged between two adjacent splints, and the return spring sleeve Set on the support shaft, the upper end of the uppermost splint is provided with a pressure plate, the upper part of the pressure plate is provided with a positioning plate, the middle part of the positioning plate runs through a positioning shaft, the positioning shaft is threaded with the positioning plate, and the lower end of the positioning shaft is connected with the pressure plate in rotation . The invention has the beneficial effects of improving aging quality, shortening aging time, improving production quality and the like.

Description

technical field [0001] The invention relates to a lithium battery aging technology, in particular to a polymer cell aging fixture and an aging process using the fixture. Background technique [0002] At present, after the formation of polymer lithium-ion batteries, they need to be placed in an aging box in a regular, orderly, and layered manner for aging. After at least 12 hours of aging; pull out the battery and proceed to the next operation. The function of the whole aging is to completely react the side reactions that have not completely reacted in the battery, so that the various substances inside the battery are in a relatively stable state, and at the same time, all the gases generated by the side reactions inside the battery are exhausted as much as possible. Air pockets for subsequent removal. However, in the existing technology, the battery cells are not subjected to external force, and it takes a long time to age, which reduces the production efficiency. Moreove...
