Abstract

Abstract : Hollow Mn-doped Fe2 O3 /PPy nanospheres have been fabricated, which exhibited excellent electrochemical performance as an anode material for lithium-ion batteries. Abstract : Mn-doped Fe2 O3 /PPy hollow composite nanospheres were fabricated by a facile solvothermal method. The Mn–Fe2 O3 /PPy electrode showed an improved electrochemical performance in terms of high rate capability and long cycling performance compared with Fe2 O3 without Mn doping and PPy coating. At current densities of 500 mA g −1 and 1000 mA g −1, the Mn–Fe2 O3 /PPy exhibited an initial capacity of 1214.7 and 924.9 mA h g −1, and the capacity was maintained at 795.7 and 643.6 mA h g −1 after 200 cycles.
