Electrochemical preparation of porous MoO 3 film with a high rate performance as anode for lithium ion batteries

A porous MoO3 film is prepared by electrodeposition on Ni foam substrates and exhibits a capacity of 650 mAh g−1 at a current density of 3 A g−1 as anodes for lithium ion batteries. Electrochemical measurements demonstrate that the outstanding rate performances are due to the improved Li+ diffusion kinetics.
