Properly recycle various used lithium ion batteries

Currently, the recycling of lithium-ion batteries is still in its infancy, with low recycling rates and serious waste. Most lithium-ion battery recycling only stops at the level of preliminary disassembly without detailed crushing and screening. In addition, due to the lack of unified standards and specifications, lithium-ion batteries produced by different manufacturers have large differences in structure, materials and processes, which brings great difficulties to recycling work.

SUNY GROUP provides a new crushing and sorting process to recycle various used lithium-ion batteries. High-value metal materials can be obtained from lithium-ion batteries through power consumption, preliminary dismantling, multiple crushing and multiple screening. The emergence of this process has greatly improved the economic benefits of recycling used lithium batteries. The specific process is as follows:

1. Discharge: Place lithium-ion batteries in specialized dissipation equipment for discharge processing to ensure safety.

2. Preliminary disassembly: Preliminarily dismantle the depleted lithium-ion battery and remove the positive electrode, negative electrode, separator, electrolyte and other materials inside the battery.

3. Multiple crushing: The battery materials after initial disassembly are subjected to multiple crushing processes to make the particle size more uniform.

4. Multiple screening: The crushed battery materials are subjected to multiple screening and classified according to particle size.

5. Resource utilization: Battery materials of different particle sizes are appropriately utilized for resource utilization, such as preparing secondary batteries and using them as building materials.
