Flame treatment of graphene oxides: cost-effective production of nanoporous graphene electrode for Lithium-ion batteries

A facile production of highly porous graphene foam by using flame treatment of graphene oxide (GO) is proposed. Highly porous architectures with randomly distributed micro-crack and micro-slit were produced due to the high temperature induced ruinous reduction and rapid expansion of GO. Synchronousl...
