Pure-phase β-Mn2V2O7 interconnected nanospheres as a high-performance lithium ion battery anode

Author affiliations

Abstract

This work primarily exhibits a systematic study of the large-scale hydrothermal synthesis of β-Mn2V2O7 interconnected nanospheres without templates. An optimal combination of hydrothermal/annealing/atmosphere parameters is identified for the pure phase, which exhibits an excellent cycling performance of 760 mA h g−1 at 0.5 A g−1 over 120 cycles and a rate capability of 470 mA h g−1 at 2 A g−1 as an anode for a lithium ion battery. Guidelines have been provided for the first time for the synthesis of β-Mn2V2O7, which opens broad opportunities for this earth-abundant chemical in electrochemical devices.
