Polypyrrole layer coated MnOx/Fe2O3 nanotubes with enhanced electrochemical performance for lithium ion batteries

Manganese oxide/iron oxide/PPy nanotubes have been firstly fabricated through a facile method. Such hierarchical nanocomposites display a high specific capacity, good cycle performance and excellent rate capability. A specific capacity of 1060 mA h g−1 is delivered after 100 cycles at the current density of 200 mA g−1.
