Lithium Battery Recycling
1. Industry Pain Points The stock of retired lithium batteries in China is surging year by year, with demand for recycling power batteries, energy storage batteries, and digital waste batteries continuing to explode. However, traditional lithium battery recycling processes generally have many shortcomings. Most small recycling production lines rely on manual pretreatment, open crushing, and simple mechanical sorting, with low overall automation. First, there are significant safety hazards: manual disassembly and open crushing of batteries with residual charge can easily cause fire and thermal runaway, posing extremely high plant safety risks. Second, environmental compliance is poor: traditional equipment cannot effectively handle electrolyte exhaust gas, dust, and volatile organic compounds, easily causing exhaust gas and dust leakage, with low EIA approval rates and high rectification costs. At the same time, traditional processes have poor resource utilization: copper and aluminum are mixed, black mass loss is severe, overall metal recovery rate is low, and enterprise profit margins are limited. Additionally, traditional equipment has cumbersome processes, long pretreatment time, and high labor input, resulting in low production efficiency that struggles to meet large-scale, compliant mass production requirements, severely constraining the stable operation and expansion development of lithium battery recycling enterprises. 2. Solution Introduction Addressing the five major pain points of poor safety, weak environmental performance, low recovery rate, high labor costs, and difficult compliance in the industry, we have created an integrated fully automatic lithium battery recycling solution, compatible with all types of waste lithium batteries including ternary, LFP, cylindrical, and pouch cells, suitable for small and medium recycling plants and large-scale regeneration bases, achieving safe crushing, pollution-free treatment, high-precision sorting, and fully closed-loop efficient resource regeneration of waste batteries. The entire production line abandons traditional water immersion pre-discharge processes, adopting nitrogen-sealed protective crushing technology that can directly process charged waste batteries, eliminating lengthy discharge procedures, significantly shortening the production process, and preventing battery fire and explosion risks from the source. The equipment operates under full negative pressure sealing, preventing dust leakage and electrolyte odor diffusion, ensuring a clean and compliant production environment. The crushed mixed materials enter a low-temperature oxygen-free pyrolysis system, which constantly decomposes organic impurities such as internal electrolyte and binders at constant temperature, thoroughly stripping cathode and anode black mass, copper and aluminum metals, and separator plastics, solving the industry challenge of material adhesion and incomplete sorting. After pyrolysis treatment, the materials enter a multi-stage composite sorting system, using a multi-process combination of magnetic separation, air classification, gravity separation, and eddy current separation to layer by layer separate iron impurities, plastic separators, copper particles, aluminum particles, and battery black mass, with high sorting precision that effectively reduces high-value material loss. Simultaneously, a complete set of closed-loop exhaust gas and dust purification systems is equipped, with exhaust gas purified through multiple stages to meet emission standards, with zero secondary pollution. The entire set of equipment is equipped with an intelligent control system featuring fully automatic start/stop, automatic operation and maintenance, and real-time monitoring of equipment temperature and chamber environment, significantly reducing manual attendance and lowering operational costs, fully meeting the three core requirements of environmental acceptance, safety production, and large-scale mass production, helping enterprises easily achieve compliant production and stable profitability. 3.
