     Transition metal oxides compositing with carbon materials have been developed as the potential anodes for lithium ion batteries, however, some expensive carbon resources and complex preparation steps have limit their practical application. To overcome these issues, herein a dandelion-like manganese multiple-oxides with simple fiber carbon was synthesized using simple carbon made from filter paper. From the microscopy observation, the morphology of as-prepared material both include the dandelion-like three-dimensional nanospheres and needle-type manganese oxides onto a carbon fiber substrate. When applied as the anodes, the fiber carbon-based manganese oxides electrode present an initial capacity of 1172.66 mAh g−1 discharged at a current density of 0.2 A g−1 and maintain over 900 mAh g−1 after 100 cycles. Meanwhile they display excellent cycling stability at 0.5 A g−1 and 1 A g−1 after 500 cycles. Actually the integrated three-dimensional nanostructure with fiber carbon as a stable skeleton enables fast transfer of electrons and ions, thus contributing to excellent electrochemical conductivity and admirable cycle stability. We provide a simple and practical method for manufacturing high performance anodes for lithium-ion batteries, especially in industrial use.
