Rational Design of Hierarchical MnO@N-doped Carbon Nanowires as a High-Performance Anode for Lithium-Ion Batteries

A facile synthesis strategy for hierarchical MnO@N-doped carbon nanowires was developed using a single in situ pyrolysis of Mn-based coordination polymers. Core-shell MnO@N-doped carbon building blocks are interconnected into a mesoporous nanowire. The artificial nanocomposite facilitates fast transport of Li+ ions and electrons and buffers the MnO volume change during Li insertion/extraction processes. As a consequence, hierarchical MnO@N-doped carbon nanowires display a promising electrochemical performance, such as a high reversible capacity, excellent cycling stability and rate capability, as an anode material for lithium-ion batteries.
