Abstract
Al and Li elements were co_doped into host spinel lithium manganese oxide by a simple and economical preparation technology . There was an investigation of the influence of doped Al contents on the initial capacity and cycling performance of the materials. The investigation of the XRD patterns, the analysis of the SEM micrographs and the determination of IR spectroscopy showed that the particles of dopant materials are fine, narrowly distributed and well crystallized, and the bonds Mn_O are stronger than these of undoped materials. The resulted materials have a high initial capacity of 119 mAh/g and good cycling characterization. The capacity still kept at 106 mAh/g after 200 cycles.
