文摘

Free-standing heterogeneous hybrid papers based on mesoporous ¦Ã-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 ¦Ã-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?¡Á?10²?S?cm^?1 with high flexibility, which makes them substrate- and binder-free. For 50?wt % mesoporous ¦Ã-MnO₂ particle-loaded anodes, a high reversible capacity of 934?mA?h?g^?1 (0.01-3.0?V) is maintained after 150 cycles.
