This study first reports the synthesis of the nanosized LiVPO4F/graphene composite (LVPF/G). The LVPF/G composite is prepared by a facile mechanochemical approach. XRD results reveal that the prepared composite are well crystallized with triclinic LiVPO4F. SEM and TEM images demonstrate that the LiV...
