Recycling opportunities for graphitic carbon from lithium-ion battery (LIB) anodes have been neglected owing to the relative low value of application. In this study, the potential methods for removing toxic metals (lead, barium, and cadmium) and organic compounds (2,4-dinitrotoluene [DNT], 2,4,6-trinitrotoluene [TNT], hexahydro-1,3,5-trinitro-1,3,5-triazine [RDX], and 2,4-dichlorophenol [DCP]) with anode carbonaceous material (ACM) obtained from the anodes of spent LIBs were evaluated. The sorption ability of ACM for lead is higher (the maximal sorption capacity is 43.5 mg/g) than for barium and cadmium. Similarly, the maximal sorption capacity of ACM for DCP is 6.5 mg/g, which is higher than those for TNT and DNT (2.6 and 2.3 mg/L, respectively). As a catalyst, ACM significantly enhances oxidation by persulfate with zero-valent iron and reduction by dithiothreitol (DTT) and hydrogen sulfides for nitro compounds. In addition, the graphitic properties enhance the redox reactions. The results suggest that ACM from spent LIBs may be an effective sorbent and catalyst in redox processes for the remediation of contaminated water and soil.

由于应用的价值相对较低，因此从锂离子电池（LIB）阳极回收石墨碳的机会已被忽略。在这项研究中，潜在的方法去除有毒金属（铅，钡和镉）和有机化合物（2,4-二硝基甲苯[DNT]，2,4,6-三硝基甲苯[TNT]，六氢-1,3,5评估了从废LIB阳极获得的阳极碳质材料（ACM）的-trinitro-1,3,5-triazine [RDX]和2,4-二氯苯酚[DCP]。ACM对铅的吸附能力比钡和镉高（最大吸附能力为43.5 mg / g）。同样，ACM对DCP的最大吸附容量为6.5 mg / g，高于TNT和DNT的最大吸附容量（分别为2.6和2.3 mg / L）。作为催化剂，ACM可显着增强过硫酸盐与零价铁的氧化作用，以及二硫苏糖醇（DTT）和硫化氢对硝基化合物的还原作用。另外，石墨性质增强了氧化还原反应。结果表明，用过的LIB产生的ACM在氧化还原过程中可能是有效的吸附剂和催化剂，用于修复受污染的水和土壤。
