Ultrafast synthesis of Mn0.8Co0.2CO3/graphene composite as anode material by microwave solvothermal strategy with enhanced Li storage properties

摘要: Abstract Carbonate is recently studied as anode material for lithium ion battery due to its relatively high capacity compared relative oxides. In order improve the time-efficiency of synthesis, an ultrafast solvothermal process assisted with microwave carried out obtain well-constructed Mn 0.8 Co 0.2 CO 3 /graphene composite batteries. The as-prepared a graphene amount 17.5 wt% exhibits morphology cubic particles in without any impurity. delivers initial charge capacities 1033 mAh g −1 . And after 120 cycles, charge/discharge 737/735 mAh g are maintained at 0.2 A g Even 2 A g , can still deliver 500/501 mAh g It promising carbonate/graphene materials rapidly through such by application.
