This work demonstrates a facile synthesis of 2D layered Mo-MOF@ppy 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, Mo-MOF@ppy has a better electrochemical performance than pure Mo-MOF. Mo-MOF@ppy 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 Mo-MOF@ppy is a promising new anode material for LIBs.

这项工作证明了通过回流加热和涂覆方法作为锂离子电池（LIBs）中的负极材料，可以轻松合成二维层状 Mo-MOF@ppy。具有二维层状结构的 Mo-MOF 可以加速整个复合材料内部的电子转移。Mo-MOF 作为电化学反应过程中的前体，提供高价 Mo 结合更多的 Li ⁺，导致 Mo-MOF 优异的电化学性能。同时，包覆的导电聚合物聚吡咯（ppy）可以促进电子转移并提高复合材料的导电性。结合这些优点，Mo-MOF@ppy 比纯 Mo-MOF 具有更好的电化学性能。Mo-MOF@ppy在 100 mA g ^-l的电流密度下可以达到 930 mAh g ^-1并在 500 mA g ^-l的电流密度下在 200 次循环后保持 750 mAh g ^-l。结果表明，Mo-MOF@ppy 是一种很有前途的锂离子电池负极材料。
