A treatment method of cathode material production wastewater -- technology of preparing ultrapure water and recovering high-purity lithium salt
Time:2020-04-15

1. Background information

In the process of manufacturing ternary cathode material, the excess lithium salt exists on the surface and inside of the material in the form of Li oxide, reacts with H2O and CO2 in the air to generate LiOH and Li2CO3 again, and remains on the surface of the material.

At present, water washing method is widely used to reduce the amount of residual lithium on the surface of ternary cathode materials. Water washing will produce wastewater containing lithium, nickel, cobalt, manganese and other metal ions. The wastewater contains valuable metals and cannot be directly reused or discharged. In view of this situation, StarOne has developed a treatment method of cathode material production wastewater - the technology of preparing ultrapure water and recovering high-purity lithium salt.

2. StarOne process

According to the customer's water quality and quantity, StarOne can make the water in the wastewater into pure water and ultra pure water. The lithium can be made into lithium carbonate and lithium hydroxide for recovery.

3. Advantages of StarOne's new process

1. Realize the full recycling of lithium salts and valuable metals.

2. The quality of produced water reaches ultrapure water and can be reused directly.

3. Strong impact resistance, applicable to wide water quality fluctuation, and stable system operation.

4. The operating cost is only 1 / 3 of the total evaporator, and the investment payback period is less than 2 years.
