Facile synthesis of β-MnO2/polypyrrole nanorods and their enhanced lithium-storage properties

Abstract

In this work, a β-MnO₂/polypyrrole (β-MnO₂/PPy) composite was prepared by a facile solvothermal method. The conductivity of the polymer PPy deposited on the surface of MnO₂ can significantly improve the electronic conductivity and accommodate the volume change. Compared with pristine β-MnO₂, β-MnO₂/PPy exhibited excellent cycling performance and superior rate capability when used as anode for lithium-ion batteries.
