Abstract
Porous cadmium electrodes were discharged galvanostatically at current densities between 2 mA/cm2 and 200 mA/cm2 in 30% at 25°C, and the discharge profiles were determined by chemical analyses of thin sections sliced from the electrode. The discharge profiles were given by , where A is the state of discharge at the front of the electrode and B is an electrochemical Thiele parameter. The retention of the discharge product in the electrode affected the discharge noticeably. The discharge efficiency was limited by both faradaic processes and mass transfer.Keywords
