← ScienceWhich risk increases disproportionately when electrolyte solution temperature drops within an electric double-layer capacitor?
A)Increased mechanical stress on electrodes
B)Decreased ion mobility and conductivity✓
C)Enhanced rate of chemical degradation
D)Increased electrostatic force on ions
💡 Explanation
Decreased temperature reduces ion kinetic energy, thus reducing the effective Diffusion Coefficient during ionic transport within the double-layer, leading to decreased ion mobility and conductivity; therefore impedance increases, diminishing EDLC performance, rather than other thermal or mechanical effects.
