Lithium battery recycling and treatment equipment Physical methods Recycling technology

With the continuous high-speed growth of new energy vehicle production and sales, it is expected that in the next 2-3 years, there will be a wave of large-scale replacement of power lithium batteries, and the scale of power battery recycling will continue to expand. Utilized by battery manufacturers and their upstream and downstream companies in the industry chain to achieve resource conservation. Car manufacturers such as NIO and power battery manufacturers such as Ningde Times have begun to layout their new energy vehicle battery swapping business. In addition, the promotion of the battery swapping mode will be beneficial for automobile manufacturers or power battery manufacturers as recycling entities to lock in the source of waste batteries in advance, achieve batch recycling, and thereby improve recycling efficiency.
The raw materials generated from battery recycling mainly include positive and negative electrode materials, electrolytes, electrolyte solvents, separators, binders, etc. The physical method of lithium battery recycling and treatment equipment recycling technology refers to the process of crushing, screening, magnetic separation, fine crushing, and classification of the internal components of waste power batteries, such as electrode active substances, fluid collectors, and battery shells, to obtain valuable products, which is environmentally friendly. The process of power battery recycling has gradually formed a "dry method as the main method, supplemented by other technologies". The lithium battery recycling process includes two stages: pre-treatment and subsequent treatment:
The pre-treatment process of lithium battery recycling and treatment equipment first requires the complete discharge of waste batteries using physical methods, and then the battery is disassembled to separate the components such as positive electrode, negative electrode, electrolyte, and separator. The subsequent processing stage involves the recycling of high-value components from various types of dismantled waste materials, among which the difficult and valuable parts that have been extensively studied should belong to the recycling of energy metals in the positive electrode active materials of batteries.
The booming development of the new energy vehicle market has led to a sharp increase in demand for power battery materials. Driven by market demand, upstream raw materials such as nickel, cobalt, and lithium have experienced an imbalance in supply and demand, leading to a surge in raw material prices, putting great pressure on downstream positive electrode material and power battery companies to purchase raw materials. The supply side of nickel, cobalt, and lithium is relatively tight. Therefore, the recycling of waste power lithium batteries will achieve the reuse of the above-mentioned metal materials, and manufacturers can resist the negative impact of price fluctuations of some battery materials from the supply side, creating higher recycling profits.
