dc.description.abstract | The electrochemical properties of LiNi0.8Co0.15Al0.05O2 as a cathode material prepared by a simple spray drying process are investigated. Citric acid, which is used as the chelating agent, enables the production of the lithium-containing precursor powders with uniform compositions from the water-soluble metal salts by a spray drying process. The post-treatment of the precursor powders under an atmosphere of oxygen results in a cathode material in the form of a powder with good electrochemical properties. The composition of the powders is determined by inductively coupled plasma analysis to be Li1.05Ni0.81Co0.15Al0.04O2. The discharge capacities of the powders post-treated at 750 degrees C after the 1st and 100th cycles are 188 and 178 mA h g(-1), respectively. The simple spray drying process is successfully applied to the preparation of precursors of the cathode material with complex compositions. The electrochemical properties of the micron sized LiNi0.8Co0.15Al0.05O2 aggregates with a filled morphology prepared from the precursor powders obtained by the spray drying process are also investigated. The aggregated powders obtained by the second spray drying process show a discharge capacity of 161 mA h g(-1) after 100 cycles. | - |
