Hefei Hengli Helps with Battery Cell Repair and Recycling of Battery Materials

In the process of battery manufacturing and recycling, the handling of positive electrode scraps, scrapped electrode pieces, and unqualified electrode pieces has always been a focus of industry attention. The positive electrode material has high value, but the electrode sheet contains components such as aluminum foil, PVDF binder, and electrolyte residue. If the treatment is uneven and unstable, it can easily cause damage to the active material, oxidation of the aluminum foil, and fluctuations in the quality of black powder, affecting subsequent repair and reuse; At the same time, traditional treatment methods also have problems such as long cycles, high energy consumption, insufficient sealing, and high pressure for exhaust gas disposal.

The high-temperature pyrolysis rotary furnace in the Hengli equipment waste battery recycling and pretreatment line can be used for the front-end heat treatment of positive electrode sheet repair. The equipment operates under inert atmosphere protection, and through continuous dynamic flipping, the electrode plates are heated more evenly, helping to achieve electrolyte evaporation, PVDF decomposition, and effective separation of materials and foils, creating more stable conditions for subsequent positive electrode material repair, screening, and reuse.

In response to the requirements for temperature, atmosphere, and consistency in electrode repair, Hengli Equipment's waste battery recycling rotary furnace has the characteristics of good sealing, stable temperature control, and strong processing continuity. The oxygen content in the furnace can be controlled at PPM level, and the temperature curve can be customized according to different materials and process requirements to reduce quality fluctuations caused by over burning and under burning. At the same time, the system can be equipped with exhaust gas treatment units, taking into account production efficiency, safe operation, and environmental protection requirements.

Based on more than 30 years of experience in the research and manufacturing of thermal equipment, Hefei Hengli Equipment applies high-temperature and complex atmosphere equipment technology to the field of new energy resource recycling, providing more stable and reliable equipment support for positive electrode sheet repair and waste battery pretreatment.
