A historical introduction is given to previous research & understanding of materials in Li ion battery. Mobile IT devices usually have used layered lithium metal hydroxides that has larger theoretical capacity than 3D oxide materials. Today, new regions of energy generation and consumption appear. Many automobile company approach to electrification. For the mid-term, they will increase its use of hybrid technology, and introduce plug-in hybrid electric (PHEV). For the long-term, they will focus on the battery electric vehicles (BEV) on the market. Above all, high power and safety are the most important requirements in their electric vehicle system. One of new worlds is energy storage system (ESS). This technology and market also will grow up with renewable energy generations. This technology also need safer batteries and materials than commodity products. In this lecture, I will introduce the new material in lithium ion battery. Nano-sized Lithium Iron (II) Phosphate (LFP) was prepared as Li ion battery cathode material and extensively studied from 1996 when Dr Goodenough introduces at first. LFP has been celebrated in many publications as being more environment-benign than layered lithium metal oxides. This was despite use of sophisticated techniques such as carbo-reducing and carbo-thermal methods.
