Question 1(20 points)
Find the following information for a Ni/Zn battery in an alkaline solution based on geometric and
physical property data given below:
a) Determine the difference in potential across the cell that corresponds to an average current
density of 4640A*m-2 and surface overpotentials of sNi=-0.2225V and sZn=0.0627V.
Assume that the concentration overpotential is negligible (10 points).
b) Calculate the Wagner number for the Zn and Ni electrodes when iavg=4640A*m-2. Would the
current distribution be uniform or non-uniform? Please justify your answer (10 points).
