Carbonate is recently studied as anode material for lithium ion battery due to its relatively high capacity compared to relative oxides. In order to improve the time-efficiency of synthesis, an ultrafast solvothermal process assisted with microwave is carried out to obtain well-constructed Mn0.8Co0.2CO3/graphene composite as anode material for lithium ion batteries. The as-prepared Mn0.8Co0.2CO3/graphene composite with a graphene amount of 17.5 wt% exhibits a morphology of cubic particles in graphene without any impurity. Mn0.8Co0.2CO3/graphene delivers high initial charge capacities of 1033 mAh g(-1). And after 120 cycles, charge/discharge capacities of 737/735 mAh g(-1) are maintained at 0.2 A g(-1). Even at 2 A g(-1), the composite can still deliver high charge/discharge capacities of 500/501 mAh g(-1). It is promising to obtain carbonate/graphene anode materials rapidly through such ultrafast solvothermal process assisted by microwave for application. (C) 2017 Elsevier B.V. All rights reserved.
