The results shows: (1)charge-transferresistance R3 decreases at first and then increases with the increasing of DOD;
结果表明：（1）随放电深度的增加，电荷传递阻抗R3先减小后增大；
2
The ohmic resistance and the chargetransferresistance of the battery are increased with the increasing of delivered capacity.
随着电池输出容量的增加，欧姆电阻和电荷传递电阻增大。
3
We find that the surface area of carbon electrodes has markedly influences on the chargetransferresistance, the efficiency of catalytic process of I3 - ions, and the energy conversion efficiency.
