摘要	Multi-walled carbon nanotubes (MWCNTs) were interpenetrated together to form a 3-dimensional porous structure, multi-walled carbon nanotube paper (WCNTP), by a floating catalyst method. The as-synthesized MWCNTP was employed as an air cathode for non-aqueous Li-O-2 batteries without the addition of any binder or conductive additives. A huge specific capacity of 34 600 mA h g(-1) could be obtained at a current density of 500 mA g(-1). 50 cycles of continuous discharge and charge have been achieved with no capacity loss at 250 mA g(-1), with a cut-off capacity of 1000 mA h g(-1). The reversible formation and decomposition of the discharge product Li2O2 was clearly revealed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). These results suggest the great potential of the binder-free MWCNTPs as air cathodes for Li-O-2 batteries with high energy density.
