Overcharge-induced impedance increase behavior of large format lithium-ion batteries with LiyNi1/3Co1/3Mn1/3O2+LiyMn2O4 composite cathode is studied in this paper.Capacity fading and increase of impedance were observed after the batteries were overcharged to different state of charge (SOC) higher than 100％.
