晶质石墨活化提纯锂离子电池负极材料机理研究

Study on the activation and purification mechanism of scaly graphite from the anode material of lithium ion battery

研究了一种新的石墨提纯方法:先焙烧石墨,然后用NaOH,H_2SO_4和HCl处理,并确定了最佳工艺条件.结果表明,这种方法可以使固定碳质量分数为95.12%的晶质石墨提纯到99.76%.

A novel graphite purification method is studied that the graphite is roasted firstly and then handled with Na OH,H2SO4,HCl.The best processing condition is confirmed through the research.The results show that the new process can purify the scaly graphite with the fixed carbon content of 95.12% to 99.76%.
