Facile Synthesis of Mn-Doped ZnO Porous Nanosheets as Anode Materials for Lithium Ion Batteries with a Better Cycle Durability

摘要

Porous Zn~(1??? x )Mn~( x )O ( x ?=?0.1, 0.2, 0.44) nanosheets were prepared by a low-cost, large-scale production and simple approach, and the applications of these nanosheets as an anode material for Li-ion batteries (LIBs) were explored. Electrochemical measurements showed that the porous Zn~(0.8)Mn~(0.2)O nanosheets still delivered a stable reversible capacity of 210?mA?h?g_(?1) at a current rate of 120?mA?g_(?1) up to 300?cycles. These results suggest that the facile synthetic method of producing porous Zn~(0.8)Mn~(0.2)O nanostructure can realize a better cycle durability with stable reversible capacity.
