Lithium ion batteries (LIBs) are the most widely used electrochemical storage devices for portable electronics, electric vehicles and power supplies. So, developing of high energy density electrodes for LIB is primary importance to meet the challenges in electronics and automobile industries in the near future. In addition, ever-greater scientific efforts toward the search for design of new materials could requires continuous improvement in terms of energy and power density. Currently, transition metal oxides and sulfides are attractive candidates as energy storage materials in various application because of their high theoretical capacities. However, ion storage process through a conversion reaction causes a structural change and amorphization that involves large volume expansion leading to cycle fading and low initial coulombic efficiency. In this research, we introduce a simple strategy for structural stability of conversion reaction-based materials for LIBs. |
