Aqueous supercapacitors of high energy density based on MoO3 nanoplates as anode material

MoO3 nanoplates were prepared as anode material for aqueous supercapacitors. They can deliver a high energy density of 45 W h kg(-1) at 450 W kg(-1) and even maintain 29 W h kg(-1) at 2 kWkg(-1) in 0.5MLi(2) SO4 aqueous electrolyte. These results present a new direction to explore non-carbon anode materials.
