Super capacitors, also known as ultracapacitors or double-layer capacitors, are one of the three major passive electronic components, positioned between traditional capacitors and rechargeable batteries. They possess the ability to store electrical charge like chemical batteries while also having the discharge capabilities of traditional capacitors. Super capacitors are characterized by high energy density and rapid charge-discharge capabilities.
Super capacitors mainly consist of electrodes, a current collector, a separator between electrodes, and an electrolyte. Activated carbon is one of the raw materials used in making super capacitors. Activated carbon is well-known for its strong adsorption properties, typically used to eliminate odors. So, why can activated carbon be used in the production of super capacitors?
Activated Carbon has a Large Surface Area
Activated carbon has a large surface area, which enhances its adsorption capacity, allowing it to adsorb a significant number of ions and molecules. In super capacitors, activated carbon serves as an electrode material with its high specific surface area, providing more surface area for charge separation and storage, thus increasing the capacitor’s capacitance.
Activated Carbon Exhibits Good Conductivity
As an electrode material, activated carbon possesses low resistance and electron migration resistance, effectively improving the charging and discharging speed and energy conversion efficiency of super capacitors.
Activated Carbon Demonstrates Good Stability
Super capacitors undergo numerous charge-discharge cycles in practical applications. Therefore, electrode materials must have good durability and stability. Activated carbon, owing to its unique structure and chemical properties, is corrosion-resistant and durable. It can maintain high performance stability over extended periods of use, thus extending the super capacitor’s operational lifespan.
Because activated carbon possesses these advantages, it is widely used in the production of super capacitors, providing better performance and broader development prospects for super capacitor applications.
