Waste lithium batteries contain a variety of valuable metal elements such as copper, nickel, aluminum, etc. If they are randomly discarded, they will cause serious waste of resources and cause environmental pollution. Lithium ion batteries are made of lithium cobalt oxide positive electrodes, Carbon material negative electrode, diaphragm organic matter, electrolyte, positive and negative current collectors, explosion-proof disk, sealing ring, top cover, shell, etc., recycling waste lithium batteries, extracting the metal, and recycling it is sustainable Direction of development.
Scrap lithium battery recycling process
1. Rolling and crushing the waste lithium battery to obtain the primary fragments; in the crushing process, the electrolyte is removed by the electrolyte adsorption collection device;
2. Cut and crush the primary fragment materials to obtain the secondary fragment materials; in the cutting and crushing process, the electrolyte adsorption collection device is used to remove the electrolyte;
3. The secondary debris material enters the plastic material separation and collection device to realize the separation of the plastic material from the electrode material and the current collector;
4. Send the second-level fragments after separating and removing the plastic materials into a hammer mill for deep pulverization to obtain the third-level fragments;
5. The three-stage debris material enters the battery material separation device for primary separation and collection, and the positive and negative electrode materials and the current collector particle mixture are obtained respectively;
6. The positive and negative electrode materials enter the cyclone for secondary separation and collection to obtain the negative electrode material graphite and the positive electrode material; the current collector particle mixture enters the vibrating screen to be further separated to obtain copper and aluminum particles. Lithium battery recycling and treatment equipment uses physical methods to separate and collect the components of waste lithium batteries, and use simple dry methods such as mechanical crushing, vacuum separation, vibration screening, specific gravity separation, and airflow separation to realize electrode materials in waste lithium batteries. Separation and collection of current collector metals, plastic diaphragms, and battery casings.
