Abstract:
Li[Li (1/3-x) Mn (2/3-x) Ni x Co x ]O 2 (x=0.1, 0.15, 0.2, 0.22, 0.25) compounds were synthesized and studied by the X-ray diffraction method and electrochemical techniques. The XRD analysis showed that these compounds could be classified as the α-NaFeO 2 structure type. Both a and c parameters decreased linearly, while c/a increased with the increase of Ni and Co content. The first discharge capacity increases with increasing lithium content at the 3 a sites in the Li[Li (1/3-x) Mn (2/3-x) Ni x Co x ]O 2 . A Li[Li 0.23 Mn 0.57 Ni 0.1 Co 0.1 ]O 2 electrode delivers discharge capacities of 238 mAh/g at C/10 between 4.6V and 2.5V.
