Hierarchical CoFe2O4/NiFe2O4 nanocomposites with enhanced electrochemical capacitive properties
Source abstract
Abstract
Hierarchical CoFe2O4/NiFe2O4 nanocomposites are prepared via a facile hydrothermal method, in which CoFe2O4 nanoparticles are coated by NiFe2O4 nanoparticles to form a novel nanostructure. Comparing with the single component of either CoFe2O4 electrodes or NiFe2O4 electrodes, the as-prepared hierarchical CoFe2O4/NiFe2O4 nanocomposites electrodes deliver a higher specific capacitance of 269 F g−1 at a current density of 1 A g−1 and exhibit capacity retention of 81% after 10000 charge–discharge cycles. The improved electrochemical performance demonstrates that hierarchical CoFe2O4/NiFe2O4 nanocomposites are promising materials and provide a new idea for future generation supercapacitors.
