Abstract: A method of forming an electrode material includes: (1) loading an electrochemically active material onto graphene sheets; (2) combining the electrochemically active material-loaded graphene sheets with holey graphene oxide sheets to form a mixture; and (3) treating the mixture under reducing conditions to form a composite including a graphene framework loaded with the electrochemically active material.
