N2 - The arduous duty cycles (current rate, state of charge and temperature) of the electric vehicle cause degradation of the Li-ion battery. This coupled with high cost of Li-ion batteries have hampered widespread adoption of electric vehicles. The degradation mechanisms are attributed to (1) electrolyte window stability and (2) solid electrolyte interphase layer on the battery electrodes. Following degradation of the battery, about 80 percent of the initial capacity is still retained [2]. With such a high capacity retained, an indication that the bulk materials in the battery are still active, it becomes advantageous to explore means of developing processes for remanufacturing of the battery after first life cycle. This study will discuss possible process of remanufacturing LiFePO 4 battery. This will be done by removal of solid electrolyte interface (SEI) on the cathode which hinders the mobility of ions in the cell.
