Which outcome usually accompanies overcharging in lithium-ion capacitors?

A)Electrolyte decomposition and gas formation
B)Increased dielectric breakdown threshold
C)Higher internal equivalent series resistance
D)Cathode material lattice structural reconfiguration

💡 Explanation

Electrolyte decomposition and gas formation results, because exceeding voltage limits enforces parasitic redox reactions via Electrolysis; this generates gas, which risks cell swelling, therefore limiting recharge voltage rather than increasing tolerance or modifying electrode arrangement.
