摘要: 采用一种新颖的物理方法——磁力研磨法制备石墨片纳米材料,该方法能够高效的将初始鳞片石墨剥离破碎至纳米级别。研究发现,制备得到的纳米石墨片(Graphite nanosheet)具有一定的含氧官能团,并且随研磨时间增加,其比表面积可增加至804 m2·g-1。电化学性能测试结果表明,在0.1 A·g-1的电流密度下,最大比电容量可达到266.8 F·g-1,体现出了良好的电化学性能。 |

Abstract: A new physics method of magnetic grinding was provided to produce nanographite, which can efficiently break flake graphite to nanoscale. The obtained graphite nanosheets possessed oxygen-containing groups and it's specific surface area could reach to 804 m2·g-1 with increase of grinding time. The electrochemical data showed that the capacitance of the graphite nanosheet was 266.8 F·g-1 under the current density of 0.1 A·g-1, indicating excellent electrochemical performance. |
