Structural and electrochemical investigation of LiNi0.8Co0.2-xMxO2 (M = Al, Al plus Mg, Al plus Mg plus Fe) synthesized by solid-state method

Lithium nickel cobalt oxide materials doped with Al, Mg, and Fe were synthesized by solid-state reaction at 800 degrees C for 18 h to study the effects of adding transition and nontransition metals to the structure. Crystalline compounds were obtained as revealed by powder X-ray diffraction (XRD). E...
