dc.description.abstract | In lithium ion batteries, lithium cobalt oxide is extensively used as a cathode material. However, cobalt has high cost and toxicity, researchers have been investigating for the development of a cobalt free cathode material. LiMn0.5Ni0.5O2 is one of the most alternative materials due to its high capacity and energy density. Besides, Al is used to improve the stability. Al-substituted LiMn0.5Ni0.5O 2 exhibits high rate capability and cycle performance. The hydrothermal method of LiMn0.5-xNi0.5-xAl 2xO2 (x = 0.01, 0.02, 0.05, 0.1) results in enhancement of electrochemical performance and stability. The precursors were prepared by stirring in a mixture of de-ionized water and NH4OH for 2h. Afterwards, the mixtures were heated in a Teflon lined autoclave for 4h followed by calcination at 900 °C for 12h. The cyclic performance of LiMn 0.5-xNi0.5-xAl2xO2 was measured in the range of 2.0 to 4.5 V. It was observed that LiMn0.5-xNi 0.5-xAl2xO2 exhibited the highest capacity at x = 0.05. | - |
