FAQ about Electric Double Layer Capacitors (EDLC), Supercapacitors
-
1. What is the difference between an EDLC and a supercapacitor?
There are some differences between EDLC (Electrochemical Double Layer Capacitor) and supercapacitors in terms of definition, working principle, and application scenarios.
Definition and Basic Concepts
EDLC: EDLC is a capacitor that uses the electrochemical double layer effect to store electrical energy. It stores charge by forming a double electric layer on the electrode surface and has the characteristics of high specific capacitance and fast charging and discharging.
Supercapacitor: Supercapacitor usually refers to EDLC, which is an electrochemical element that stores energy by polarizing electrolytes and has the characteristics of high power density and long cycle life.
Working Principle
EDLC: The working principle of EDLC is based on the electrochemical double layer theory, which stores charge by forming a double electric layer on the electrode surface. This structure enables EDLC to complete the charging and discharging process in a very short time and has a high energy density.
Supercapacitor: The energy storage mechanism of supercapacitor is the same as that of EDLC, which uses the electrochemical double layer effect to store electrical energy. Its working principle is to store and release charge by polarizing electrolytes. -
2. What is the double layer in supercapacitors?
The double layer in supercapacitor refers to the situation that when a conductive electrode (such as porous activated carbon material) is immersed in an electrolyte solution, the electrode surface and the liquid interface will form excess charges of opposite signs due to uneven charge distribution on both sides, thereby generating a potential difference between the interfaces. This phenomenon is the basis for the formation of the double layer. Specifically, the double layer consists of an inner Helm layer (a compact adsorption layer close to the electrode surface) and a diffusion layer (an ion distribution layer close to the electrolyte side).
The formation process of the double layer
Uneven charge distribution: When a conductive electrode is immersed in an electrolyte solution, the electrode surface and the liquid interface will form excess charges of opposite signs due to uneven charge distribution on both sides.
Electric field action: Under the action of the electric field, the positive and negative ions in the electrolyte will quickly move to the electrode surface, forming a compact charge layer at the positive and negative electrodes, namely the double layer.
Charge accumulation: The formation of the double layer depends on the electron enrichment on the electrode surface and the redistribution of ions in the electrolyte, and energy storage is achieved through the accumulation of interfacial charges. -

Supercapacitor: The energy storage mechanism of supercapacitor is the same as that of EDLC, both of which use the electrochemical double layer effect to store electrical energy. Its working principle is to store and release charge by polarizing electrolytes.
Application Scenarios
EDLC: Due to the characteristics of fast charging and discharging and high energy density, EDLC is widely used in situations that require fast energy release and recovery, such as car starting systems, electronic equipment backup power supplies, etc.
Supercapacitors: Supercapacitors are also suitable for application scenarios that require fast charging and discharging and high energy density, such as electric vehicles, solar power generation systems, uninterruptible power supplies (UPS), etc.
In addition, supercapacitors are also commonly used in situations that require high power output, such as hybrid vehicles and peak power devices.
