Chromium-ion doped spinel lithium manganate nanoparticles derived from the sol-gel process

The chromium-ion doped spinel lithium manganate nanoparticles derived from the sol-gel process were studied. The microstructural morphology and the particle size of the calcined specimens were examined by transmission electron microscopy (TEM). The composition of the obtained cathode powders was characterized via x-ray diffraction (XRD) using monochromated CuK £\ radiation.
