212th ECS Meeting, Abstract #750, © The Electrochemical Society Comparison of electrochemical behavior in different LiFePO4-based commercial cells

In recent years, a significant effort has been devoted to developing low-cost materials for lithium-ion batteries (LIB). LiFePO4 is one of the most promising positive electrode materials for use in LIB. Several manufacturers are commercializing cells with LiFePO4-based chemistry. It is of interest to evaluate these cells and compare their electrochemical behavior and stability for various power source applications. Our preliminary studies suggest that selections of different materials, processing conditions, and cell configurations resulted in different performance characteristics and the capacity retention over life. As our experiences in the number of samples and length of tests increase, the dependence of cell performance and life on material synthesis method, processing condition and cell configuration may begin to show signs of influence
