Tailoring NiO@NiFe2O4/CNTs triphase hybrids towards high-performance anode for lithium-ion batteries

NiFe(2)O(4 )has attracted great attention in the field of energy storage, but its application is limited due to the serious volume expansion. NiO@NiFe2O4/CNTs triphase hybrids were tailored through simple hydrothermal method with the regulation of CNTs content in triphase hybrids. The results of electrochemical performance study indicate that NiO@NiFe2O4/90CNTs triphase hybrid with CNTs content of 61.759% exhibits high discharge specific capacity of 721.65 mAh g-1 at 0.1 A g(-1) after 100 cycles, and almost 1000 mAh g(-1) at 0.5 A g(-1) after 300 cycles. The distinguished electrochemical performance is due to the synergistic effect of NiO@ NiFe2O4 and CNTs, as well as the tailoring of NiO@NiFe2O4/CNTs triphase hybrids. This work demonstates that NiO@NiFe2O4/CNTs triphase hybrid is a superb anode material for lithium-ion batteries and the importance of tailoring materials, providing new insights for searching next generation of lithium storage materials.
