0.25Cu 0.25Zn 0.5Fe 2O 4/NiFe 2O 4 nanocomposites: A promising anode material for high-performance lithium-ion battery]]>

摘要

AbstractIn this article, for the first time, we are reporting on the electrochemical lithium storage properties of hollow Mg0.25Cu0.25Zn0.5Fe2O4/NiFe2O4nanocomposites. The nanocomposites exhibit excellent cycling performance with a capacity of 661 and 460?mA?h?g?1after 500 cycles at a very high rate of 300 and 1000?mA?g?1, respectively. Such superior performance over other Fe based mixed metal oxides is produced by the combination of the composite and the hollow structures. In virtue of the excellent electrochemical performance, hollow Mg0.25Cu0.25Zn0.5Fe2O4/NiFe2O4nanocomposites have huge potential as anode materials for the next-generation lithium ion batteries.Graphical abstractDisplay OmittedHighlights?First report on Mg0.25Cu0.25Zn0.5Fe2O4/NiFe2O4nanocomposites as anode for LIBs.?The nanocomposites are synthesized by one-pot ultrasonic spray pyrolysis process.?The capacities are 661 and 460?mA?h?g?1after 500 cycles at 300 and 1000?mA?g?1.?Superior performance is endowed by synergic effect and composite's hollow structure.]]>
