Effect of ball milling time on graphene nanosheets Ball milling can effectively disperse GNSs into Al matrix in two aspects: one is the homogeneity in macroscopic scale and the other is the exfoliation of thicker GNSs to thin GNSs in microscopic scale. A maximum tensile strength (∼276 MPa) was achieved only with 0.3 wt% GNSs when the ball

LiMnPO 4 is anticipated to be a promising cathode material for next generation lithium battery. A reduction of particle size is recognized as a good strategy to improve its performance and it can be achieved by ball milling. However, the ball milling including carbon addition forms small LiMnPO 4 particles with large carbon content, which leads to low volumetric energy density of electrode.
