Abstract

MnO is a promising anode material for LIBs due to its low cost and high theoretical capacity, but large volume changes and low conductivity limit its application. To improve its conductivity and electron transport rate, we fabricated mesoporous MnO/C hollow microtube through a hydrodynamic force-induced rapid assembly in T-type microchannel reactor followed with a sintering process. The as-synthesized mesoporous MnO/C hollow microtube is consist of MnO nanograins with abundant porous reaction sites embedding uniformly on carbon layers to form a hollow tubular-like structure. When used this mesoporous MnO/C hollow microtube as an anode material of LIBs, it can deliver a high reversible capacity of 845 mAh
