Abstract The surface of as-prepared LiMn 2 O 4 was modified with Al 2 O 3 by a melting impregnation method. X-ray diffraction, field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) studies indicated that Al 2 O 3 nano-particles are distributed around the spinel. X ray absorption fine structure analysis (XAFS) further demonstrated that Al atoms were also doped to the surface of LiMn 2 O 4 particles. The nano-Al 2 O 3 particle coating improves the capacity… CONTINUE READING
