本文采用一种新的粉碎方法制备了纳米石墨片作为铝离子电池的负极材料。电化学测试结果表明，SGN具有很高的放电容量、优异的倍率性能和良好的循环稳定性，这主要是由于SGN的棱面增大、厚度减小和结晶度高。本工作为制备高性能的石墨基AIB材料提供了一条新的途径。
Here, we prepared small graphite nanoflakes (SGN) by a new strategy of pulverization as the cathode of aluminum ion batteries (AIBs). Electrochemical measurements show that SGN has a very high discharge capacity, excellent rate performance and good cycling stability mainly due to its enlarged edge plane, reduced thickness and high crystallinity. This work provides a new route for preparing high performance graphite-based materials for AIBs.
