Activated Carbon Basics
Structure and Properties
You can think of activated carbon as a sponge with millions of tiny holes. These holes, called pores, give the material a huge surface area. In fact, one gram of activated carbon can have a surface area greater than 2,200 square meters. This means you get more space for storing energy in a small amount of material.
Here is a table that shows the main structural features of activated carbon:
Characteristic | Description |
|---|---|
Specific Surface Area | High specific surface area (≥ 2227 m²/g) helps store more charge. |
Micropores | Pores between 0.4 and 0.8 nanometers, perfect for trapping ions and molecules. |
Mesopores | Pores between 3 and 4 nanometers, which let ions move quickly and easily. |
You will find that the mix of micropores and mesopores is important. Micropores hold the ions, while mesopores help ions move in and out. This structure makes activated carbon very good for energy storage devices.
Why It’s Ideal for Energy Storage
You might wonder why activated carbon works so well in batteries and supercapacitors. The answer lies in its pore size and surface area. When you use activated carbon with many ultramicropores (smaller than 1 nanometer), you get better capacitance. These tiny pores let ions stick to the surface, which helps store more energy. Mesopores make it easier for ions to travel, especially when the ions are large.
You also benefit from the electrical properties of activated carbon. It conducts electricity well, which is important for fast charging and discharging. Many scientists use activated carbon from biomass, which supports environmental sustainability. You can use New Energy Activated Carbon as both an anode and a cathode in lithium batteries.
