Constructive designing of ternary metal oxide as an anode material for high performance lithium-ion batteries
Summary
Rational design of ternary transition metal oxides for electrochemical energystorage and conversion application is highly desirable due to their synergeticeffect and structural modifications. In this regards, binder-free urchin-like Mnsubstituted NiCo2O4microspheres grown on conducting substrate by co-precipitation method followed by calcination. Direct growth of active materialon nickel foam (Mn0.1Ni0.9Co2O4/NF) results in a high reversible capacity of1076 mAh/g at current density of 1.6 A/g and excellent stability of 350 cycles.As compared to bimetallic NiCo2O4, improved electrochemical performance ofMn substituted NiCo2O4is mainly ascribed to the 3D structure with high sur-face area and abundant mesopores, which can efficiently reduce the diffusionlength of ions and improve the structural stability by providing enough spacefor volume expansion during delithiation/lithiation processes.
