How to solve the waste lithium battery scientifically and effectively

The copper in the negative electrode of lithium batteries (with a content of about 35%) is a widely used critical processing raw material, and the carbon powder adhered to it can be used as an additive for plastics, rubber, etc. Therefore, the effective separation of the negative electrode constituent materials of the waste lithium battery has a promotional purpose for maximizing the resource utilization of the waste lithium battery and eliminating its corresponding environmental impact. Commonly used methods for recycling waste lithium batteries include hydrometallurgy, pyrometallurgy, and mechanical and physical methods. Compared with the wet method and the fire method, the mechanical physical method does not require the use of chemical reagents, and has lower energy consumption, which is an environmentally friendly and efficient method. Based on the structural characteristics of the negative electrode of the lithium battery, a combined process of fracture screening and airflow separation is used to carry out separation and enrichment research to realize the efficient separation and recovery of copper, aluminum and carbon powder in the negative electrode of the waste lithium battery. The lithium battery pole piece solution equipment can realize the resource utilization of the metal copper and carbon powder in the negative electrode material of the waste lithium battery through the combined process of hammer vibration rupture, vibration screening and airflow sorting; the negative electrode material can effectively realize the carbon powder after the hammer vibration rupture The mutual peeling between the copper foil and the copper foil can be preliminarily separated from the carbon powder by vibrating sieving based on the difference in size and shape between particles. It is mainly used for lithium battery processing manufacturers to separate the aluminum and copper materials from the anode and cathode materials in the scrapped positive and negative electrodes for the purpose of recycling. With the large-scale use of lithium batteries, and recycling of lithium batteries has huge economic benefits, foreign companies have established specialized battery recycling solutions. The domestic lithium battery recycling technology started late, and most of the recycling solutions are still in the experimental stage, and large-scale industrial processing has not been formed. But in the future, we can choose to develop based on the actual situation in our country. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
