Abstract
Li-rich spinel-type lithium manganate (SC) coated LiMn2O4 composites were prepared and characterized by XRD, SEM, FT-IR, ICP, etc. Their charge/discharge behaviors were studied between 3.0 and 4.3 V at 40 mA g−1 under room temperature, and the results showed that SC coated on surface of LiMn2O4 could improve cycling stability of composite electrodes. The composite (S1) containing 4.8 wt% of SC exhibited noticeably improved cycling stability, whereas the initial specific capacity was very close to that of LiMn2O4.
