Abstract: Hollow Cu₂O spheres with highly porous shells were synthesized via a facile one-pot solution route at low temperature. The resultant Cu₂O spheres were characterized by means of XRD, SEM, TEM and BET techniques. The results show that the typical diameters of the prepared Cu₂O hollow spheres are 100-300 nm. Each Cu₂O sphere is constructed of small nanoparticles. Electrochemical tests reveal that the hollow Cu₂O spheres have very high and stable lithium ion (Li ⁺) storage capacities of 412.5 mAh g^-1 at 0.5C after 100 cycles. The superior Li storage performance of the Cu₂O spheres is due to their highly porous nanostructure and fine spherical morphology. The prepared Cu₂O spheres show great promise for use as high performance anode materials for lithium ion batteries (LIBs).
