抜粋

Li_3.5+xTi₅O₁₂ and Li₄Ti ₅O₁₂ layers coated LiMn₂O₄ were prepared via sol-gel route, with subsequent annealing at 750 C. XRD studies showed coating did not change the structure of LiMn₂O₄. TEM studies showed coating layers were formed around LiMn₂O ₄ particles, both corresponding spinel LiTiO phase. XPS studies showed the valence of surface Mn for the Li_3.5Ti₅O ₁₂-coated-LiMn₂O₄ increased after annealing. This sample also demonstrated a favorable cycling performance.
