Abstract
The LiMn2O4 thin films for Li secondary batteries have been prepared by a RF magnetron sputtering method. In this research, we have prepared LiMn2O4 films under various preparation conditions. The charge-discharge characteristics of these films were evaluated. Several films showed good charge-discharge curve and good voltage, but charge-discharge efficiency was not so good. It was shown that the capacity of a film was approximately half of the theoretical value.
