From 1980s, the successful commercialization of Lithium-ion battery (LIB) has advanced the production of portable electronics such as laptops, mobile phones, cameras by the development of Information Technology (IT). This evolution led to a demand for rechargeable batteries with greater capacities, higher energy density, and a reduction in size and weight. Lead-acid, nickel-cadmium, and nickel-metal hydride batteries are some conventional rechargeable batteries which were available for development. They used aqueous electrolytes, which limit the increase of energy density and the reducing of size and weight. Therefore, there has been a crucial need for new, small, and lightweight batteries, which are to be put into practical usage. LIBs are one of the most advanced rechargeable batteries, attracting a lot of attention in recent years. LIBs exhibit some excellent properties such as high capacity and energy density, low cost, and can operate at high current [1]. In LIBs, cathodes, anodes, and electrolyte all play significant roles in batteries performance. In particular, the cathodes material is considered to have the most impact in the operation of the cell. Cathode has the effect on the diffusion activity of Li+ ion, which determines the capacity of the batteries. There are several types of cathode material, like LiCoO2, LiMnO2, LiFePO4. Among these materials, LiFePO4 (LFP) shows several advantages compared to others. It is low-cost manufacturing, thermal stability, abundant in nature, and environmental friendliness. However, this material suffers from low conductivity and Li+ diffusion rate, which hinders the performance of LIBs. Therefore, the are some methods to improve the properties of LFP, such as reducing particle size, doping and carbon coating. There are several methods for synthesizing LFP cathode material, such as sol gel method, hydrothermal method, co-precipitation method and solid-state method. Coprecipitation method combined with solid state method is the popular choice because of its low cost, fast operation time and the result materials have uniform structure.
