With the explosive growth of the new energy vehicle and energy storage industries, the annual decommissioning volume of waste lithium batteries in China has entered the million-ton era. The issuance of the Guidelines for the Construction of Recycling Systems for Lithium-Ion Batteries in Electric Bicycles in early 2025 has further highlighted the urgency of standardized recycling. Against this backdrop, Jiangxi Mingxin Metallurgical Equipment Co., Ltd. has built a safe and efficient resource recycling system relying on its independently developed charged crushing and recycling technology, setting a technical benchmark for the industry.
As a "National High-Tech Enterprise" holding 3 national invention patents and over 20 utility model patents, Jiangxi Mingxin has been deeply engaged in the environmental protection equipment field for more than 30 years. Its scientific research achievement of "complete sets of equipment for resource utilization of waste electronic products" has reached the advanced domestic level. The company's newly developed "charged crushing treatment device for scrapped lithium-ion power batteries" adopts a nitrogen-protected oxygen-free crushing system, which strictly controls the oxygen concentration in the treatment chamber below 2%, fundamentally eliminating the explosion risk caused by electrolyte volatilization in traditional crushing processes. This innovative design omits the lengthy discharge pretreatment process in traditional technologies, increasing processing efficiency by over 30% and perfectly addressing the industry pain point of balancing safety and efficiency.
In terms of resource recovery accuracy, Jiangxi Mingxin's intelligent sorting matrix demonstrates strong capabilities. Integrating magnetic separation, air flow separation, and multi-stage screening technologies, the system achieves a copper tab recovery rate of over 99.5%, aluminum shell purity of more than 98%, and a sorting accuracy of 99% for nickel-cobalt-manganese (NCM) and lithium iron phosphate (LFP) materials. Equipped with a full closed-loop environmental protection system, it achieves a VOCs removal rate of over 99.9% and a dust emission concentration controlled below 10mg/m³ through activated carbon adsorption and catalytic combustion treatment, surpassing EU environmental standards and truly realizing the green transformation of "turning waste into treasure".
According to industry data calculations, the processing line adopting Jiangxi Mingxin's recycling route can achieve a single-line processing capacity of 5 tons per hour. For every 10,000 tons of waste lithium batteries processed, it can reduce carbon emissions by 23,000 tons, save 1,200 tons of cobalt resources, and 800 tons of lithium resources. This technical advantage is even more valuable amid the complex environment of weak supply and demand and profit inversion in the lithium battery recycling market in the first half of 2025. With its metal recovery rate 30% higher than traditional processes, it can create annual revenue of over 100 million yuan for 10,000-ton-level processing enterprises.
The full-chain "crushing-sorting-purification" solution built by Jiangxi Mingxin fully aligns with the development principle of "enterprise-led, safe and convenient" in the Guidelines. Through the industry-university-research cooperation model, the company has jointly established technological innovation platforms with multiple universities. Its independently developed supporting equipment such as dryers and drum screens for lithium battery crushing and recycling further enhances the automation and refinement level of the recycling system. Currently, the company's products have been exported to many countries and regions around the world, providing key support for the supply chain closed loop of international enterprises such as Tesla.
As the "dual carbon" strategy advances in depth, Jiangxi Mingxin will continue to leverage its advantages as a provincial-level specialized, refined, characteristic, and innovative enterprise. Based on existing technologies, it will develop the fourth-generation "supercritical fluid separation technology", aiming to increase the recovery purity of positive and negative electrode materials to 99.9%. This development model driven by technological innovation for resource recycling not only provides a safe and efficient solution for China's lithium battery recycling industry but also contributes "Chinese wisdom" to the resource security of the new energy industry chain through the development and utilization of "urban mines".
