Depolarization effect to enhance the performance of lithium ions batteries

The polarization effect and depolarization effect in electrode materials: LiMn1.5Ni0.5O4 (left) and LiFePO4 (right). Before depolarization effect, a large difference in potential between the anodic and cathodic peaks can be observed (polarization). After Fe doping in LiMn1.5Ni0.5O4 and cycling in aqueous electrolyte for LiFePO4, the differences in potential between the anodic and cathodic peaks are greatly reduced (depolarization effect).200
