Abstract
Free-standing heterogeneous hybrid papers based on mesoporous g-MnO2 particles and acid-treated single-walled carbon nanotubes (a-SWCNTs) for lithium-ion battery anodes are successfully prepared by simple vacuum filtration. The mesoporous g-MnO2 particles with high surface areas are well dispersed throughout these anodes by being bound in nanoporous a-SWCNT networks. Furthermore, these anodes exhibit a high electrical conductivity of 2.5 102 S cm 1 with high flexibility, which makes them substrate- and binder-free. For 50 wt% mesoporous g-MnO2 particle-loaded anodes, a high reversible capacity of 934 mA h g 1 (0.01e3.0 V) is maintained after 150 cycles.
