The microwave irradiation technique (MWIT) was applied to synthesize lithium manganese oxide having spinel structure using LiOH·H2O and ε–MnO2 as starting materials. The crystal and electronic structure depends on the irradiation time; x-ray diffraction patterns of the sample irradiated for 9 min were in good agreement with that of cubic structure without showing the peak of MnO2. The electronic structure of synthesized samples before and after lithium ion intercalation and/or deintercalation was investigated by Mn L-edge and O K-edge x-ray absorption spectroscopy.

Lithium manganese oxide (LiMn2O4) had been a promising material for lithium-ion and thin film batteries. However, the LiMn2O4 had some problems such as the manganese dissolution into liquid electrolyte. In order to improve cycleability, we introduced SnOx layer as protective layer. This layer was deposited on spinel LiMn2O4 by using radio frequency magnetron sputtering. The deposited SnOx layer fully covered the LiMn2O4 , and didn’t make a change the crystallinity of the spinel films. The SnOx layer prevented direct contact of liquid electrolyte and improved the cycle retention.
