Mobile Phone Lithium Battery Recycling Machine

The cobalt, lithium, copper and plastic in used cell phone lithium batteries are valuable resources with high recovery value. Therefore, the scientific and effective treatment and disposal of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. Lithium battery is mainly composed of shell, positive electrode, negative electrode, electrolyte and diaphragm. The positive electrode is composed of lithium cobaltate powder coated on both sides of the aluminum foil collector through PVDF, which plays a bonding role; the negative electrode structure is similar to the positive electrode, composed of carbon powder bonded on both sides of the copper foil collector. At present, the research on the resourceization of waste lithium batteries mainly focuses on the recovery of high-value cobalt and lithium precious metals from the positive electrode, and the separation and recovery of negative electrode materials is rarely reported. In order to alleviate the increasingly serious problem of resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to achieve full-component recycling of waste materials. The copper (about 35%) in the negative electrode of waste lithium batteries is an important production material widely used, and the carbon powder adhered to it can be used as additives in plastics and rubber. Therefore, the effective separation of the constituent materials of waste lithium battery cathode is a driving force to achieve the maximum resource utilization of waste lithium battery and eliminate its corresponding environmental impact. The working principle is to crush the raw material to below 10mm with crusher, then enter the particle crusher for stripping and crushing, and then enter the micro powder classifier for separation and treatment, and the tail ash is collected by the back cyclone separator and pulse dust collector.
