Abstract: 
Engineering electrodes with desirable nanostructures are regarded as an urgent challenge to achieve enhanced electrical conductivity, stable structural integrity, and advanced performance for Li+ storage. Various approaches with processing complexity and multiple reactions have suffered serious limitation in industrialization. Here, we develop a facile carbon plasma (C-plasma) strategy combined with controlled reaction temperature to achieve in situ hierarchical metallic nanoparticles and graphene-encapsulated CoMoO4 nanosheets (hCCO). The nano-frameworks of Co3Mo and graphene shell are simultaneously modulated via simply controlling reaction temperature. The incorporation of nanoalloy component effectively enhances the conductivities of nanosheet, and uniformly coated graphene releases the structural stress caused by conversion reaction of metal oxides, maximizing the capacity utilization. The synergetic combination of these advantages enables the synthesized hCCO to deliver excellent electrochemical performances. Our C-plasma exhibits a great potential in tuning nano-architectures with high-performance Li+ storage behavior.
