LiSn(0.0125)Mn(1.975)O(4) thin films possessed a large capacity of similar to 120 mA h g(-1) and a high capacity retention of > 81% relative to their initial capacity at 4 C after the 90th cycle. Such promising results are believed to originate from the Mn(4+)-richer spinel structure and the less distortion of MnO(6) octahedra. The near-edge x-ray-absorption fine structure result of the cycled LiSn(0.0125)Mn(1.975)O(4) films can be highlighted with the specific local t(2g) symmetry resulting from the interaction between Mn 3d and O 2p.
