Abstract

A Cu₃Ge/Ge@G aerogel was employed as an anode for a lithium-ion battery by a simple pyrolysis of a CuGeO₃ nanowire and graphene oxide nanosheet mixture. It is demonstrated that both the Cu₃Ge nanoparticles and graphene nanosheets act as conductive buffers to accelerate the electron migration rate and enhance the cycling stability of the electrode.
