The LiSn0.0125Mn1.975O4 thin films showed the superior properties, i.e., a high capacity retention of 94% at the current rate of 5 C after 90 cycles, due to the increase in Mn valence and the decrease in oxygen deficiency. The larger oxygen deficiency in undoped LiMn2O4 thin films was confirmed by the increased lattice volume and structural degeneration. (C) 2012 Elsevier Masson SAS. All rights reserved.
