This work demonstrates a facile synthesis of 2D layered [email protected] via reflux heating and coating methods as anode materials in the lithium-ion batteries (LIBs). Mo-MOF with two-dimensional layered structure can accelerate the transfer of electrons inside the whole composite. Mo-MOF, as a precursor in the electrochemical reaction process, provides high-valence Mo binding more Li+, resulting in excellent electrochemical performance of the Mo-MOF. Meanwhile, the coated conducting polymer polypyrrole (ppy) can promote electron transfer and enhance the conductivity of the composite materials. Combining those merits, [email protected] has a better electrochemical performance than pure Mo-MOF. [email protected] can reach 930 mAh g−1 at a current density of 100 mA g-l and maintain 750 mAh g-l at a current density of 500 mA g-l after 200 cycles. The results show that [email protected] is a promising new anode material for LIBs.
