ABSTRACT
Discovering functionalities of nanomaterials that are superior to those of bulk materials has been a challenge in fundamental science and technology. In particular, increasing industrial needs for higher-power rechargeable batteries has encouraged advanced research on nanosized electrode materials. In this chapter, we first introduce the relationship between the high-charge/discharge-rate capability and particle size of the electrode materials based on the diff usion equation. Then, we describe size-controlled synthesis of cathode materials by means of the hydrothermal method, which is indispensable for estimating size dependency. Finally, we discuss the nanosize eff ect and its influence on high-charge/discharge-rate capability of cathode materials, as well as the related structural, physical, and electrochemical properties, of cathode materials is discussed.
