Recently, energy materials have attracted much attention due to breaking the energy crisis. Especially, the attention to Lithium Ion Battery (LIB) materials largely increases because LIB is used in many applications such as portable electronic equipment, a hybrid car, an electric car, large-scale electricity storage. The research and development of LIB is carried out all over the world, reporting a large number of results. However, the performance of the LIB is now reaching its limit. A new concept rechargeable battery is required. Using Sodium (Na) and Magnesium (Mg) as charge carriers in secondary batteries is drawing attention. However, the studies on cathode materials are often found, and the study of the anode is not well understood. Graphite anode which used in LIB because of high electro conductivity, high capacity, redox voltage, and cycle life is not available in the secondary batteries using Na and Mg as charge carriers. Practical anode material for the next-generation rechargeable battery is a key. On the other hand, the electrochemical reaction in the interface between electrode material and electrolyte is very complicated, and is not clarified in detail. In addition, enough information is not provided by the comparison before and after electrochemical reaction. In-situ measurement is necessary for clarifying electrochemical reaction in detail. The purposes of this study are synthesis of next-generation rechargeable battery anode materials and clarifying a detail of electrochemical reaction in the interface between electrode material and electrolyte with the next-generation rechargeable battery by in-situ measurements. Therefore, an interdisciplinary study is conducted by a fusion of the synthesis of anode materials with the in-situ measurement.
