Using the above equation and the illustrations, show that at
30
carbon-carbon ultra-capacitor can operate at 3.4 V cell potential.
Approximate the cell potential at
30
C by tracing along the heavy line
labeled “voltage” in the chart labeled “Ultracapacitor Potential and Relative
Energy” and confirm that it does indeed pass through 3.4 V.
