In general, biomass-derived carbon or nickel oxide (NiO) served individually as anode materials for lithium ion batteries suffers from insuperable barriers due to severe defects, i.e. low specific capacity for carbon anodes, low electronic conductivity and large volume expansions for NiO anodes during cycling, etc. Herein, we proposed a strategy that combines wood-derived hollow carbon fibers with around 35 wt% nano NiO wrapped by the reduced graphene oxide (rGO). This unique structure fully integrates the merits of porous and conductive carbon...
