Abstract
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.
