Lithium battery recycling equipment innovative pyrolysis technology

 With the vigorous development of the new energy vehicle industry and the widespread popularity of electronic products, the number of waste lithium batteries has increased dramatically. Traditional recycling methods, such as crushing and high-temperature incineration processes, have problems such as high energy consumption, large environmental pollution, and low resource recovery rate. The innovative pyrolysis technology, with its high efficiency and environmentally friendly characteristics, provides a new solution for the recycling of waste lithium batteries. Zhengzhou Dingli New Energy Equipment Co., Ltd. will introduce it to you in detail! 

The pyrolysis process of waste lithium batteries is roughly pided into the following key steps:

1. Mild pyrolysis: Under the protection of an inert atmosphere (such as nitrogen, argon, etc.), waste lithium batteries that have not been pretreated are directly placed in a temperature range of 350°C to 800°C for pyrolysis for 30 to 120 minutes. The main purpose of this stage is to gently decompose organic components such as electrolytes and binders inside the battery, while avoiding oxidation or volatilization of metal elements at high temperatures. The electrolyte gas released during the pyrolysis process can be recovered by condensation, and can be reused as a chemical raw material after further purification.

2. Crushing and screening: The solid residue after pyrolysis is crushed and screened to obtain a mixture of battery crushed materials and positive and negative electrode powders. This process lays the foundation for subsequent finer separation.

3. Physical separation: The battery crushed materials then undergo a series of physical treatment methods such as magnetic separation, wind sorting, grinding, and ultrasonic screening to gradually separate high-value metal materials such as steel shells, aluminum shells, copper powders, and aluminum powders. Magnetic separation uses the magnetic differences of different materials to quickly separate ferromagnetic materials; wind sorting is based on the difference in material density to achieve the separation of light and heavy materials; grinding and ultrasonic screening further refine the particles, improve the separation accuracy, and ensure the purity and recovery rate of electrode materials (such as lithium cobalt oxide, nickel cobalt manganese oxide, etc.).

With the continuous development of the new energy vehicle industry and the improvement of environmental awareness worldwide, the innovation and application of waste lithium battery recycling technology will usher in a broader development space. As one of the leaders, innovative pyrolysis technology will become one of the mainstream technologies in the field of waste lithium battery recycling and treatment in the future with its advantages of high efficiency, environmental protection, and high resource recovery rate. At the same time, with the continuous advancement of technology and the further reduction of costs, the application scope of innovative pyrolysis technology will continue to expand, making greater contributions to promoting energy transformation and promoting green economic growth.

The innovative pyrolysis technology in lithium battery recycling and processing equipment is a technological breakthrough of great significance. It will provide more efficient and environmentally friendly solutions for the recycling and processing of waste lithium batteries, and make positive contributions to promoting sustainable development and circular economy.
