Causes Of Battery Polarization

1. The polarization caused by the resistance of each part of the battery is called ohmic polarization;
2. The polarization caused by the retardation of the charge transfer process in the electrode-electrolyte interface layer is called activation polarization;
3. The polarization caused by the slow mass transfer process in the electrode-electrolyte interface layer is called concentration polarization. The way to reduce the polarization is to increase the electrode reaction area, reduce the current density, increase the reaction temperature and improve the catalytic activity of the electrode surface.
