Synthesis and electrochemical properties of coaxial-cable nanostructure carbon wrapped manganese oxide as anode for lithium ion batteries

A novel and effective carbon wrapped manganese oxide material with coaxial-cable structure was synthesized through two processes of hydrothermal method and calcination . Transmission electron microscopy discovered that the as-prepared material had a porous manganese oxide inside core with a diameter of about 100–600 nm and a graphite cable jacket with a thickness of about 20–100 nm. The results of the electrochemical measurements exhibited that the as-prepared material had great energy density , long cycling life and favorable charge-discharge capability when it was used as an anode material in lithium ion batteries . The results revealed that the carbon wrapped manganese oxide was an excellent candidate for the anode of lithium ion batteries.
