Hefei Hengli Equipment: Used Battery Electrode Sheet Repair Production Line, Unlocking a New Path for Battery Recycling and value-added

Against the backdrop of continuous expansion in new energy battery production capacity, the volume of waste generated during battery manufacturing, including edge trimmings from electrode cutting, defective and scrapped electrode sheets, overstocked inventory, and process-obsolete electrode sheets, keeps rising steadily.

According to industry data, 3% to 5% of pole plates become waste during the production of lithium iron phosphate batteries. Most of these waste pole plates are brand-new materials that have not been filled with electrolyte or put into circulation, featuring extremely low loss of material properties and simple post-treatment processes, thus boasting extremely high value for repair and reuse.

Leveraging over 30 years of accumulation in equipment technology and in-depth experience in the lithium battery industry, Hefei Hengli Equipment has developed a targeted production line for waste battery electrode repair. The entire line consists of four core modules working in coordination: the cutting and powder removal system, the pyrolysis system, the environmental protection system, and the crushing and packaging system, covering the entire process flow of electrode repair. Among them, the core pyrolysis rotary furnace can achieve PPM-level oxygen content control, and meanwhile, the internal structure of the furnace has been optimally designed to address industry pain points such as material blockage, uneven pyrolysis, and unstable product quality, enabling stable and continuous production throughout the process, ensuring full pyrolysis of electrodes and realizing high-value recovery of electrodes. Equipped with a professional environmental protection treatment system, it strictly controls exhaust emissions throughout the process to meet the requirements of environmentally compliant production and support enterprises in achieving green and safe production.

Hefei Hengli's electrode repair production line precisely meets the internal closed-loop recycling needs of battery factories, revitalizes production waste with high-end equipment technology, reduces production costs, and enhances resource added value, providing strong equipment support for the lean production and efficient resource-based recycling of the lithium battery industry.
