A kind of flake graphite with grain size D50 of 40.3 μm from Inner Mongolia was taken in a spherification test by adopting a QCJ vortex micropulverizer, and two kinds of spherical products with D50 of 16.42 μm and 11.68 μm respectively were obtained, of which the corresponding tapped density increased from 0.46 g/cm3 to 0.95 g/cm3 and 0.80 g/cm3 respectively, presenting a total spherification rate of 50.48%. The spherical products were purified with mixed acid, with the fixed carbon content therein up to 99.95% and 99.97% respectively, and then the electrochemical performance of the products was tested. The anode material with those two products delivered initial discharge specific capacities of 366.60 mAh/g and 364.30 mAh/g, respectively, and presented initial charge-discharge efficiency of 93.40% and 92.32%, respectively. It is shown that the capacity retention rate can exceed 99% after 30 cycles at 0.1C current.

采用QCJ气流涡旋微粉机对内蒙古某D50为40.3 μm的微细鳞片石墨进行球形化试验,得到D50分别为16.42 μm和11.68 μm的2种球形化产品,对应的振实密度由原始的0.46 g/cm3分别提高到0.95 g/cm3和0.80 g/cm3,总成球率50.48%。采用混酸法将该球形产品提纯至固定碳含量99.95%与99.97%,随后进行电化学性能测试,产品负极材料首次放电容量分别为366.60 mAh/g和364.30 mAh/g,首次充放电效率分别为93.40%和92.32%;在0.1C电流下,经过30次充放电循环后,容量保持率均在99%以上。

采用QCJ气流涡旋微粉机对内蒙古某D50为40.3 μm的微细鳞片石墨进行球形化试验,得到D50分别为16.42 μm和11.68 μm的2种球形化产品,对应的振实密度由原始的0.46 g/cm3分别提高到0.95 g/cm3和0.80 g/cm3,总成球率50.48%。采用混酸法将该球形产品提纯至固定碳含量99.95%与99.97%,随后进行电化学性能测试,产品负极材料首次放电容量分别为366.60 mAh/g和364.30 mAh/g,首次充放电效率分别为93.40%和92.32%;在0.1C电流下,经过30次充放电循环后,容量保持率均在99%以上。

A kind of flake graphite with grain size D50 of 40.3 μm from Inner Mongolia was taken in a spherification test by adopting a QCJ vortex micropulverizer, and two kinds of spherical products with D50 of 16.42 μm and 11.68 μm respectively were obtained, of which the corresponding tapped density increased from 0.46 g/cm3 to 0.95 g/cm3 and 0.80 g/cm3 respectively, presenting a total spherification rate of 50.48%. The spherical products were purified with mixed acid, with the fixed carbon content therein up to 99.95% and 99.97% respectively, and then the electrochemical performance of the products was tested. The anode material with those two products delivered initial discharge specific capacities of 366.60 mAh/g and 364.30 mAh/g, respectively, and presented initial charge-discharge efficiency of 93.40% and 92.32%, respectively. It is shown that the capacity retention rate can exceed 99% after 30 cycles at 0.1C current.
