主 题：NiMo0_(4) phosphorus doping anode lithium ion batteries
摘 要：Heteroatom doping is one of the most promising strategies toward regulating intrinsically sluggish electronic conductivity and kinetic reaction of transition metal oxides for enhancing their lithium ***,we designed phosphorus-doped NiMo0_(4) nanorods(P-NiMo0_(4))by using a facile hydrothermal method and subsequent low-temperature phosphorization *** doping played an indispensable role in significantly improving electronic conductivity and the Li+diffusion kinetics of NiMo0_(4) *** investigation and density functional theory calculation demonstrated that phosphorus doping can expand the interplanar spacing and alter electronic structures of NiMo0_(4) ***,the introduced phosphorus dopant can generate some oxygen vacancies on the surface of NiMo0_(4),which can accelerate Li+diffusion kinetics and provide more active site for lithium *** excepted,P-NiMo0_(4) electrode delivered a high specific capacity(1,130 mA·g^(-1) at 100 mA·g^(-1) after 100 cycles),outstanding cycling durability(945 mA·g^(-1) at 500 mA·g^(-1) over 200 cycles),and impressive rate performance(640 mA·g^(-1)at 2,000mA·g^(-1))for lithium ion batteries(LIBs).This work could provide a potential strategy for improving intrinsic conductivity of transition metal oxides as high-performance anodes for LIBs.
