One-pot scalable synthesis of Cu–CuFe2O4/graphene composites as anode materials for lithium-ion batteries with enhanced lithium storage properties

Abstract

We develop a one-pot and scalable hydrothermal strategy to prepare nanoscale metallic Cu incorporated CuFe2O4 hexagonal platelets and graphene (Cu–CuFe2O4/G) composites at a low reaction temperature as anode materials for lithium-ion batteries (LIBs). Nanoscale metallic Cu was attached to CuFe2O4 hexagonal platelets and graphene sheets in the composites. Such structural features are responsible for exploiting the respective advantages to improve electrochemical performance. The Cu–CuFe2O4/G composites deliver a high capacity of 672 mA h g−1 after 200 cycles at a current density of 1000 mA g−1, good rate capability and cyclic stability due to the synergistic effect among CuFe2O4 hexagonal platelets, metallic Cu, and graphene sheets.
