Abstract

Layered Li[Li_0.15Ni_(0.275-x/2)Al_xMn_(0.575-x/2)]O₂ materials were synthesized via a sol-gel method at 900°C in air. Li[Li_0.15Ni_(0.275-x/2)Al_xMn_(0.575-x/2)]O₂ and Li₂MnO₃ phase mixed compounds were obtained. Substitution of Al³⁺ ions were shown to prevent the structural degradation of the electrode material allowing higher discharge capacities. The 6mol% aluminum-doped Li[Li_0.15Ni_0.245Al_0.06Mn_0.545]O₂ electrode delivered approximately 210mAhg^-1 discharge capacity in a cut-off range between 2.5 and 4.6V. It was found that the Al doping on Li[Li_0.15Ni_(0.275-x/2)Al_xMn_(0.575-x/2)]O₂ material could decrease the area specific impedance (ASI).
