Au with Pd nanoparticles were synthesized and coated onto the spinel LiMn2O4 via a coprecipitation calcination method\nwith the objective to improve the microstructure, conductivity, and electrochemical activities of pristine LiMn2O4. The novel\nLi[PdAu]xMn2?xO4 composite cathode had high phase purity, well crystallized particles, and more regular morphological\nstructures with narrow size distributions.At enlarged cycling potential ranges the Li[PdAu]xMn2?xO4 sample delivered 90mAhg?1\ndischarge capacity compared to LiMn2O4 (45mAhg?1). Itwas concluded that even a small amount of the Pd andAu enhanced both\nthe lithium diffusivity and electrochemical conductivity of the host sample due to the beneficial properties of their synergy
