Synthesis lithium metal oxide battery material

Synthesis of Lithium Metal Oxide (LiM02) -Battery Material... 

Numerous efforts are done to replace the lithium-cobalt oxide used in the first generation of commercial lithium-ion batteries by materials with low cost and environmental concerns. The development of new materials needs new synthesis procedure such as sol-gel processing, ion-exchange reaction, and hydrothermal reaction. The chemical and structural stabilities of the transition-metal oxide electrodes have been compared by studying bulk samples. In this respect, the various physicochemical techniques are welcome to design the best stmcture. Synthesis of amorphous compounds could help the knowledge of microstructures in this regard. 

To overcome the stability problem, it is obvious that an alternative approach to material synthesis would be needed. In this respect a recent report suggested that iron oxide encapsulated in meso- and macroporous carbon can be used as anode in Li batteries and reaches a greatly improved reversibility and rate performance. At the same time, a similar structure for a cathode material based on iron and lithium fluoride was synthesized and investigated. It was demonstrated that encapsulation of transition metal-metal fluoride in nanocarbon might be an effective strategy to improve the cycling performance of such a cathode material. ...
