← ScienceWhich mechanism diminishes stored energy in a degrading supercapacitor?
A)Electrolyte decomposition increases internal resistance✓
B)Electrode surface area expands significantly
C)Quantum tunneling creates charge pathways
D)Dielectric breakdown increases the capacitance
💡 Explanation
Electrolyte decomposition lowers capacitance through increased internal resistance, therefore stored energy decreases because ion transport requires greater overpotential, rather than higher capacitance via dielectric augmentations at the plates.
