α-MnO2nanotubes: high surface area and enhanced lithium battery properties

Abstract

A simple one-step route for preparing α-MnO₂ nanotubes is reported. The α-MnO₂ nanotubes exhibit a high surface area of 226 m² g⁻¹ and reversible capacity of 512 mA h g⁻¹ at a high current density of 800 mA g⁻¹ after 300 cycles, as well as cycling stability when measured as an anode in lithium batteries.
