Kinetics Study of LiFePO4 Synthesis Reaction with Solid State Method

Abstract

Lithium Ferro Phosphate (LiFePO<sub>4</sub>) is a cathode that has the advantage of abundant raw material, inexpensive and easily upgraded compared to other cathode. The method commonly used for LiFePO<sub>4</sub> synthesis is solid state. It is important to study kinetics in this process for product optimization. There are two methods in determining the kinetics of product formation including Thermogravimetric Differential Thermal Analysis (TG-DTA) and X-ray Diffraction (XRD). Meanwhile, Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). Meanwhile, CV and EIS were used to determine electrochemical kinetics.
