Innovation technology of lithium battery recycling equipment

Lithium battery recycling equipment A physical method for separating electrode current collectors and electrode materials of lithium ion batteries. Separation; the waste materials of lithium ion batteries include but are not limited to: waste lithium ion battery positive electrode, waste lithium ion battery negative electrode, mixture of waste lithium ion battery positive electrode and negative electrode, waste lithium ion battery.

The method of the invention has the advantages of high separation efficiency, simple process, no pollution, low cost, etc., and can solve the problems of pollution and recycling of waste lithium ion batteries. The pulverized mixture is subjected to magnetic fluid separation, and the electrode current collector is separated from the electrode material by adjusting the surface specific gravity of the magnetic fluid. Because the specific gravity of the general solution is smaller than that of the electrode material, the surface specific gravity of the magnetic fluid can be adjusted to be greater than that of the electrode material but smaller than that of the electrode current collector, so the effect of completely separating the electrode current collector and the electrode material can be achieved by this method.

Compared with the prior art, the present invention has the following beneficial effects:

1. Environmental protection: During the recycling process, no waste water, waste gas and waste residue are produced.

2. Recycling: During the separation process, the positive electrode current collector, the negative electrode current collector, the positive electrode material, and the negative electrode material remain in their original state, and they can be recycled without any change in chemical properties. The recycling rate of resource utilization is very high. high.
