Introduction
The global new energy industry continues to grow rapidly. As a result, the number of spent lithium batteries is also increasing. Today, waste lithium battery recycling has become an important part of the global recycling industry.
Spent lithium batteries mainly come from four sources: consumer electronics, electric vehicle batteries, energy storage systems, and defective battery cells from battery factories. These batteries contain valuable materials such as lithium, cobalt, nickel, copper, and aluminum.
However, improper disposal can waste these valuable resources. It can also cause soil and water pollution. Therefore, professional lithium battery recycling has become increasingly important.
Different Lithium Batteries Require Different Recycling Processes
Lithium batteries have different structures and material compositions. Common types include ternary lithium batteries, lithium iron phosphate batteries, and pouch cells.
Because of these differences, one recycling process cannot meet every application. Recycling companies need to select suitable lithium battery recycling equipment based on battery type, material condition, and required capacity.
For this reason, Henan Reliable Env Equipment provides customized lithium battery recycling plants for different projects. We can design systems with capacities of 300–500 kg/h, 1 ton/h, and 2 tons/h.
In addition, we can adjust the equipment configuration according to local environmental requirements and the customer’s investment budget. This approach helps customers build a recycling plant that matches their actual production needs.
Safe Crushing Is Essential for Lithium Battery Recycling
Safety remains one of the most important challenges in the lithium battery recycling process.
Waste lithium batteries may still contain residual electrical energy. During crushing, damaged batteries can cause short circuits and generate heat. In some cases, this can lead to fire or thermal runaway.
Therefore, the recycling process must control these risks before mechanical crushing.
Henan Reliable Env Equipment provides two safety solutions for waste lithium battery processing.
Solution 1: Saltwater Discharge Before Crushing
The first method uses saltwater discharge. Operators first place the waste batteries into a saltwater solution for controlled discharge.
After the batteries are fully discharged, the material needs to be thoroughly dried. It can then enter the physical crushing process.
This method helps reduce the electrical energy inside the batteries before mechanical processing.
Solution 2: Sealed Nitrogen Protection
The second method uses a sealed oxygen-free shredder.
During operation, the system continuously fills the shredding chamber with nitrogen. This reduces the oxygen concentration inside the chamber and limits the conditions required for combustion.
As a result, the system can provide additional safety during the initial shredding stage.
The suitable safety solution depends on the battery type, material condition, local regulations, and project requirements.
Multi-Stage Crushing and Separation Process
After the initial safe shredding stage, the material enters the multi-stage crushing and screening system.
First, the equipment further reduces the particle size. Then, the screening and separation equipment separates different materials according to their physical properties.
The recycling process can recover materials such as copper particles, aluminum particles, and lithium battery black powder.
Meanwhile, a properly designed separation system can improve material recovery and purity. This makes the recovered materials easier to handle and process further.
Recovering Valuable Materials from Black Powder
Black powder is one of the most valuable products in a lithium battery recycling plant.
It contains valuable battery materials that can be further refined. Through additional hydrometallurgical or other refining processes, recycling companies can recover useful battery raw materials.
These recovered materials can return to the battery manufacturing industry. Therefore, lithium battery recycling can reduce resource consumption and support a more complete circular economy.
