Effect of Different Stoichiometry on the Electrochemical Behaviour of LiCoxNi1-xO2 Cathode Materials
Pure, single phase, layered LiCoxNi1-xO2 materials with good cation ordering are not easy to synthesize. Here, solid solutions of LiCoxNi1-xO2 (x = 0.1,0.2 and 0.3) were synthesized using a self-propagating combustion route and characterized. All the materials were observed to be phase pure and that...

| Summary: | Pure, single phase, layered LiCoxNi1-xO2 materials with good cation ordering are not easy to synthesize. Here, solid solutions of LiCoxNi1-xO2 (x = 0.1,0.2 and 0.3) were synthesized using a self-propagating combustion route and characterized. All the materials were observed to be phase pure and that cobalt has been successfully substituted in the crystal lattice. Their electrochemical properties were investigated by a series of charge-discharge cycling in the voltage range of 3.0 to 4.3 V. It was found that some of the stoichiometries exhibit specific capacities comparable or better than that of LiCoO2. © Published under licence by IOP Publishing Ltd. |
