【Abstract】 The impedances of small alkaline zinc manganese dioxide batteries have been measured in the range of 0. 035 KHz at 0% .10% ,20% ,50% and 80%of discharge state respectively. The ohmic resistance and the charge transfer resistance of the battery are increased with the increasing of delivered capacity. The equivalent circuit has been established and the electrochemical parameters have been obtained from the impedance data.更多还原
