摘要

Battery failure manifested as an increase in cell impedance as a result of cathode dissolution is discussed. Analogous oxide and phosphate based materials exhibit similar electrochemical performance yet the phosphate based materials display increased structural stability and resistance to solvation formation in non-aqueous electrolytes. Structural modifications could optimize existing battery systems and address one of the main causes of increased cell impedance observed over time.
