Description
Summary:In the relentless pursuit of finding new electrode materials for lithium ion batteries (LIBs), mixed metal oxides (MMOs, containing different metal cations), have confirmed improved electrochemical activities in comparison with simple metal oxides (SMOs, containing single metal cations). On the other hand, electrodes with nano-dimension and hollow microstructure have been confirmed as advantageous candidate in LIBs. The integration of the two features into one structure can provide another chance to improve the lithium storage capabilities. In this work, for the first time we report the lithium storage property of porous Cu0.10Mg0.40Zn0.50Fe2O4/Ca2Ni5 nanocomposite as LIB anode. The nanocomposites anode delivers approximately 350 mAh g−1 after 500 cycles at 300 mA g−1. Even at a high rate of 1000 mA g−1, it also showed an excellent performance up to 1000 cycles and 90% Coulombic efficiency with no sign of capacity fading. This outstanding Li storage performance makes Cu0.10Mg0.40Zn0.50Fe2O4/Ca2Ni5 nanocomposites a promising candidate as LIB anode.
