Synthesis of several intercalating spinel cathode materials for secondary lithium cells by a simple low temperature procedure

Although several methods are available to prepare spinel cathode materials, a simple thermal method of low temperature inorganic procedure has been developed to synthesize these compounds of high purity, small particle size and good reversible behaviour on cycling. By this procedure, lithium based oxides, phosphates and boride materials were developed and these compounds can be used as secondary cathode electrodes for lithium cells. The procedure is very simple and novel. Paper presented at the 2nd International Conference on Ionic Devices, Anna University, Chennai, India, Nov. 28–30, 2003.
