What Are The Methods Of Lithium-ion Battery Recycling?

Recycling and treatment methods for used lithium-ion batteries mainly include: physical recycling, chemical recycling, biological recycling and hydrometallurgical methods. Each recycling method has its own advantages and disadvantages. So if you want to choose the method that suits your needs. It is necessary to consider the composition of lithium-ion batteries, recycling and processing capacity, economic benefits, profit analysis and other factors. At present, the lithium battery recycling market is often divided into three segments: secondary utilisation, lithium battery recycling machine (crushing and sorting), pyrometallurgy, wet extraction, etc.

Ladder utilisation

After the battery plates of new energy vehicles are retired, the used lithium batteries can be tested, screened and restructured. It can then be used in other industry sectors. Industries with low energy requirements. For example: energy storage systems, solar street lights, electric bicycles and so on.

Physical dry crushing and sorting

Lithium battery recycling machine through crushing, crushing, sorting, magnetic separation, gravity sorting, airflow wind selection and other steps. Thereby: positive and negative electrode materials, copper, aluminium, magnetic shell, plastic, etc.. The waste lithium battery is first crushed into small particles. Then use the screening machine to sort the materials with different particle sizes. Then through the magnetic separation and wind selection. Thus the plastic diaphragm non-metal and copper, aluminium,,, black mass and other metal materials are separated. Not only can it improve the recovery efficiency and purity of metal. It is mainly suitable for large-scale waste lithium battery recycling and processing. Luoyang cast advertising automated production line to achieve efficient separation. It can also reduce the amount of waste residue for subsequent treatment and also reduce the negative impact on the environment. This method can be combined with highly efficient hydrometallurgical process. It can recover precious metals in high proportion. Reduces the pressure on mining sites. Promotes the sustainability of the industry.

What Are The Methods Of Lithium-ion Battery Recycling?

Chemical Recovery Method

Separate the metal elements and organic matter in used lithium-ion batteries through chemical reaction. Commonly used chemical methods are: acid leaching method, alkali leaching method, high temperature melting method and so on. This recycling method has high recycling efficiency. The metal elements with high purity can be obtained. However, the operation process of this chemical process is complicated. And the equipment and technology requirements are high. But at the same time will produce waste water and exhaust gas and other pollutants. Need to be followed by purification treatment.

Biological recovery methods

The metal elements in used lithium batteries are extracted through biological effects. But this method is still in the research stage. Not yet mature. Recovery efficiency is low. The composition of the waste lithium battery is very demanding. The biological recycling method has the advantageous features of energy saving and environmental protection, low energy consumption and so on.

To sum up: the treatment method of used lithium batteries needs to be decided according to the specific situation. There is also a focus on environmental issues and management. Through scientific and reasonable recycling and processing methods and measures. Lithium battery recycling machine can achieve effective recycling and reuse of waste lithium batteries. It can reduce environmental pollution and harm. Promote sustainable development.
