Fe3O4/Ag microsheets assembled by interlaced nanothorns as high performance anode materials for lithium storage

200Composited Fe3O4/Ag microsheets built by interlaced nanothorns are easily fabricated by selectively etching FeAgAl source alloy in NaOH solution. On account of the distinctive hierarchical micro-/nano-structure and the hybridization of well conductive Ag, Fe3O4/Ag composite exhibits much superior lithium storage performances in comparison with the pure Fe3O4 electrode.
