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

Abstract

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.
