An alternative lithium cathode material: Synthesis, characterization, and electrochemical analysis of Li-8(Ni5Co2Mn)O-16

We have previously reported a nonaqueous solution route to LiMn2O4 and LiCo O2 materials that have demonstrated acceptable characteristics for use as l ithium battery cathode materials. Due to the flexibility of our processes, complex formulations of cathode materials can be easily generated and studi ed. Utilizing this flexibility, we have investigated a complex lithium tran sition metal oxide material, Li-8(Ni5Co2Mn)O-16, far use as an alternative cathode material. This material was analyzed by X-ray diffraction and scann ing electron microscopy techniques which indicated it was phase pure. Elect rochemical investigations revealed a high capacity (similar to 150 mAh/g) w ith a fade rate of similar to 0.41 mAh/g/cycle (0.27%/cycle). (C) 1999 The Electrochemical Society.
