Thepowdered materials were characterized using X-ray diffraction, scanning electronmicroscopy and electrochemical techniques. X-ray analyses showed that 003/104peaks intensity ratio increased from 0.95 for undoped material to 1.27 for dopedmaterial, thereby suggesting that dual doping was beneficial in terms reducingLi/Ni cation mixing. Although dual doping caused some reduction in initialdischarge capacity (140 vs. 128 mAh/g) and increase in charge transfer resistancerelative to the undoped material, it noticeably helped increase capacity retentionduring battery testing at high voltage.engEffect of Mg and Al Dual Doping on High Voltage Cycling of LiNi0.4Mn0.4Co0.2O2 Lithium-ion Battery Cathode MaterialMakale1308-6529
