The graph is telling you that if the capacitor was initially charged to 9V, as soon as you connect a resistor across it the voltage starts decaying to zero and roundabout at 5*C*R there is less than 1% of the starting voltage: - First off, you can't store voltage or current inside a capacitor.
Water-based electrolytes with high water content, up to 70 % water for low impedance, low ESR or high ripple current electrolytic capacitors with voltage ratings up to 100 V for low cost applications . ESR and ripple current will be described below, in capacitors these parameters are linked to internal heating.
The most commonly used model for electrolytic capacitors is based on Arrhenius' law, which describes the influence of the constraints related to the ambient temperature and the current flowing through the capacitors, and on the Coffin-Manson empirical law for the consideration of the applied voltage.
Preprints and early-stage research may not have been peer reviewed yet. Due to their high specific volumetric capacitance, electrolytic capacitors are used in many fields of power electronics, mainly for filtering and energy storage functions. Their characteristics change strongly with frequency, temperature and aging time.
