What Technology Is Used To Recycle Lithium-ion Batteries?

With the rapid development of the new energy vehicle industry. The demand for automotive power lithium batteries is also climbing rapidly. However. It is also facing a large number of waste lithium batteries scrapping and decommissioning. If it is not handled effectively. It will cause some pollution and harm to the environment. Therefore, lithium battery recycling technology has become the focus of public attention at present. This paper will provide a detailed introduction to the recycling and treatment technology of waste lithium batteries. Including: gradient utilisation, low temperature drying technology, high temperature pyrolysis technology, physical sorting technology, wet extraction technology and so on.

1. Terraced use: for decommissioned batteries, again after testing, screening, restructuring and so on. Then re-apply to the lower energy requirements of the industry to continue to use. For example: energy storage systems, electric bicycles, solar photovoltaic panels and other industries. So as to realise the re-use, ladder use.

2. Physical sorting technology: lithium battery recycling machine through the waste lithium batteries for shredding, crushing, high-speed crushing, airflow sorting, gravity sorting, three-level screening sorting. So as to achieve effective recovery of valuable materials and metals in the waste lithium battery. Can be sorted out: black, copper, aluminium, plastic, nickel belt, etc.

3. Low temperature drying technology: mechanical heating under the condition of inert gas protection. Achieve effective separation of organic matter and split material. It can prevent aluminium, lithium and other materials will not appear oxidation and aging. It can also effectively remove the organic matter and electrolyte in the battery. It does not affect the recovery rate, and at the same time, it can improve the recovery of valuable metal elements.

4. High-temperature pyrolysis technology: heating the waste lithium battery under nitrogen protection system. Thus effectively removing the binder, organic matter, electrolyte, etc. in the battery. Realise the shedding of electrode material powder. Efficient recycling. Simultaneous separation and recovery of copper and aluminium. Can be matched with lithium battery recycling machine. The technology has high recycling and processing efficiency. But it needs to control the pyrolysis temperature and pyrolysis atmosphere. So as to avoid safety hazards and environmental pollution.

5. Wet extraction: this wet recycling technology recovery of high purity. But it is more cumbersome. Recovery costs. Usually combined with the sorting method (lithium battery recycling machine). Separate out the black matter after wet extraction to extract the valuable rare metals: lithium, cobalt, nickel and other metal elements. Waste lithium batteries are crushed and dissolved, and the metal elements in the leaching solution are selected and separated using suitable chemical reagents. Produce high quality metals and compounds. Thus, it is directly recycled. Hydrometallurgical technology has the advantageous characteristics of high recovery efficiency and high metal taste. It is one of the important technologies in the field of lithium battery recycling.
