One article interpretation - Hefei Hengli waste electrode repair equipment

With the continuous expansion of production capacity in the lithium battery industry, the number of waste electrode sheets generated during the production process of lithium batteries is also rapidly increasing. Valuable resources such as high-purity positive electrode battery materials and copper aluminum foil are hidden in the scraps generated during coating and cutting processes, as well as in the scrapped electrode rolls without liquid injection.

Faced with these waste electrode pieces, the treatment methods of enterprises are often simple and crude - selling battery electrode pieces containing high-value positive electrode materials as low-priced metal waste directly to waste recycling companies, or using simple crushing and powder making processes to sell black powder with excessive impurities at a low price, resulting in serious profit losses.

In response to the pain points in this industry, Hefei Hengli relies on more than 30 years of advanced thermal equipment manufacturing technology accumulation, combined with mature core technology, to create a battery electrode regeneration and repair solution, enabling high-value recycling of waste electrode pieces.

The core of this solution is the core equipment that Hengli Equipment Company has fully verified in the field of waste battery recycling: cutting and peeling off the waste electrode sheets and sending them into an atmosphere rotary furnace. Through precise temperature and atmosphere control, the PVDF binder between the current collector and the positive electrode material is efficiently decomposed, causing the current collector and positive electrode black powder to automatically dissociate.

At the same time, a complete environmental protection treatment system is established to address the organic waste gas, dust, fluoride and other pollutants generated during the treatment process. Ultimately, various environmental indicators such as VOCs, fluoride, and particulate matter emissions far exceed national standards and comply with local standards, completely eliminating environmental compliance risks for enterprises.

Hefei Hengli has been deeply engaged in the field of high-end thermal equipment for more than 30 years, and the related core equipment has been verified in a large number of waste battery recycling projects. This set of waste electrode piece repair solutions not only solves the problem of waste treatment in battery factories, but also turns waste electrode pieces into high-value recycled raw materials, helping the lithium battery industry develop towards green recycling and achieving a win-win situation for economic and environmental benefits!
