Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of energy conservation and environmental protection for electric vehicles, and specifically to a disassembly device for blade lithium batteries. Background Art
[0002] Due to the limited service life of lithium batteries, a large number of waste lithium batteries are generated. Taking ternary material batteries as an example, their positive electrodes contain a large amount of precious metals, among which cobalt accounts for 5 ~ - 20%, nickel accounts for 5 ~ - 12%, manganese accounts for 7 ~ - 10%, lithium accounts for 2 ~ - 5% and 7% plastic. Most of the contained metals are rare metals and should be reasonably recycled and reused. For example, cobalt, as a strategic resource, is widely used in various fields, such as superalloys in addition to lithium batteries. It can be estimated that the recovery volume of precious metals is huge. For these discarded battery cells, there are two types of subsequent treatment paths: secondary utilization or direct material recovery. Secondary utilization means continuous use, and ultimately it still needs to be disassembled.
[0003] Lithium batteries usually have two design structures. One is the wound structure, and the other is the laminated structure. The wound structure lithium battery is wound into a cylindrical structure in the order of positive electrode sheet, separator, and negative electrode sheet; the lithium battery with this structure has a simple structure, low technical threshold, and high popularity rate. The disadvantage is low space utilization rate, stress concentration at the bending part of the electrode sheet, and during the charging and discharging process of the battery, the electrode sheet is easily punctured, resulting in short circuit and causing fire. The blade lithium battery structure adopts a structure where the positive electrode sheet, separator, negative electrode sheet, separator, positive electrode sheet... are stacked layer by layer. The positive and negative electrode sheets are placed flat without folding, and the space utilization rate is high. In recent years, blade lithium batteries have been widely promoted and used.
