During capacitor discharge there will be an initial voltage drop due to the ESR followed by a voltage drop due to the reduction in energy stored in the capacitor, these are known as resistive and capacitive voltage drops. When sizing supercapacitors consider the capacitive component and the resistive component. The capacitive component represents the voltage change due to the change in energy within the supercapacitor. The resistive component represents the voltage change due to the Equivalent Series Resistance (ESR) of the supercapacitor. Temperature and voltage directly affect the life or aging of supercapacitors. Life Extends 2.2 times every 10°C, Life Extends 2.2 times for 0.2 V reduction, and the Arrenius plots shown here help to visualize the temperature and voltage effects.
