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

In this work, a beta-MnO2/polypyrrole (beta-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 beta-MnO2, beta-MnO2/PPy exhibited excellent cycling performance and superior rate capability when used as anode for lithium-ion batteries.
