Process Workflow and Equipment for Lithium Battery Recycling

Standardized lithium battery recycling not only achieves resource recycling but also has positive implications for environmental protection. This article systematically introduces the lithium battery recycling process and explains the equipment required for key stages, hoping to provide a reference for investors in the battery recycling business.

The lithium battery recycling workflow generally includes pretreatment, crushing, and sorting stages, each requiring corresponding equipment and technology.

1. Pretreatment Stage

Waste lithium batteries first need to undergo safe discharge treatment to remove residual charge and eliminate the risk of short circuits, ensuring operational safety. This step is crucial for safety and subsequent processing efficiency. Common lithium battery discharge methods include using salt water or specialized discharge chambers.

2. Crushing and Grinding Stage-Lithium battery dismantling crusher&Lithium battery grinding machine

The lithium battery casing is disassembled to expose the internal materials. Then, specialized crushing and grinding machines are used to break the battery components into small particles, preparing for material separation. The crushed battery materials undergo screening and magnetic separation to initially separate different components such as the casing, diaphragm, and electrode materials.

3. Material Sorting Stage-Lithium battery components screen separator&Airflow sorting machine

This stage aims to further separate valuable materials from the lithium battery. Physical sorting methods, such as airflow separation and vibrating sieving, are used to separate precious metals (copper, aluminum) and black mass (containing lithium, cobalt, nickel) and other impurities. Finally, the sorted materials can be refined to meet industry purity standards for use in the production of new batteries.

A complete lithium battery recycling production line requires the coordinated operation of multiple types of equipment. DOING can provide a variety of equipment, from battery pretreatment to material recycling. In particular, its lithium battery crushing and sorting machine demonstrates significant advantages: employing multi-stage crushing and sorting, through magnetic separation, precision screening, and airflow separation, it achieves a material recovery rate of over 98%, extracting high-purity recyclables that can be directly reintegrated into the manufacturing supply chain.
