Molybdenum sulfide/graphene composites are promising anode materials for lithium‐ion batteries (LIBs). In this work, MoS x /graphene composite film with an ideal 3D porous structure is developed via a facile and straightforward electrochemical route. The MoS x nanoparticles are uniformly anchored on the graphene nanosheets that are randomly arranged, resulting in MoS x /graphene composites with well‐developed porous structure. Benefiting from such structure and the synergistic effect from two components, this material shows a high specific capacity over 1200 mA h g −1 , an excellent rate performance, and superior cycling stability. The dominating pseudocapacitive behavior in Li storage contributes to the outstanding rate capacity. Importantly, this kind of novel material can be easily produced as 3D microelectrodes for microscaled LIBs that are highly demanded for autonomous microelectronic systems.
