Description

Technical Field

[0002] Due to the limited service life of lithium batteries, a large number of waste lithium batteries are also produced. Taking China as an example, in 2024, the number of discarded lithium batteries in my country will exceed about 40 billion, with a total weight of more than about 5 million tons. Taking ternary material batteries as an example, their positive electrodes contain a large amount of precious metals, of which cobalt accounts for 5%. ~ 20%, nickel accounts for 5 ~ 12%, manganese accounts for 7 ~ 10%, lithium accounts for 2 ~ 5% and 7% plastics, most of the metals they contain are rare metals, which should be reasonably recycled and reused. For example, cobalt, as a strategic resource, is widely used in various fields, including lithium batteries and high-temperature alloys. It can be inferred that the amount of precious metals recycled is huge. According to the three-year service life of commercial vehicles and the five-year service life of passenger vehicles, a peak of power lithium battery retirement will be experienced in 2025. There are two types of subsequent processing paths for these discarded batteries, cascade utilization or direct material recycling. Cascade utilization means continuous use, and eventually it will have to be disassembled.

The disadvantage is that the space utilization rate is low, and the stress is concentrated at the bend of the electrode. During the battery charging and discharging process, the electrode is easily punctured, resulting in a short circuit and fire.
