1. One of the main principles of supercapacitors is electric double layer building. This is the principle that a double ion layer is formed when the electrolyte is close to the electrode surface. This allows more charge to be stored in the double layer as the voltage increases, and thus more energy to be stored at a higher voltage. (Electric Double Layers)
2. As the voltage increases, the current required to charge the supercapacitor decreases, which means that the charging time decreases.
3. The higher the voltage, the faster the charge movement, so the charging time decreases.
If I = Q/t constant current Q decreases, then t also decreases.
Is this right?
Beomseok Kim, I think your question is wrong, because in GCD, current and time are compared, not voltage. In fact, in the GCD method, we enter the current and time and get the voltage. The reason for the reduction of charge-discharge time with increasing current is related to the capacity relationship for GCD.
