Synthesis of Double-Shelled LiMn2O4 Hollow Microspheres with Enhanced Electrochemical Performance for Lithium Ion Batteries

open access: yesInternational Journal of Electrochemical Science, 2013
Double-shelled LiMn2O4 hollow microspheres have been prepared from hydrothermally synthesized urchin-like α-MnO2 spheres. A large hollow interior and broad gap between exterior and interior shells are clearly observed within the hollow microspheres ...
