Carbon Materials for Supercapacitors

Porous Carbon Materials for Supercapacitors and Adsorption

The  team is developing porous carbon materials with high specific surface area, uniform pore size distribution and interconnected porosity to enhance performance in electrochemical capacitors (supercapacitors). We also functionalize these carbons with heteroatom-containing groups (such as oxygen, nitrogen and sulfur) to tune surface chemistry and improve electrochemical response. We aim to understand the relationships between structural and surface properties of carbon materials and their performance, including charge storage mechanisms and ageing behavior. In addition to energy storage, these porous carbons are studied for environmental applications such as air and water purification.

Research Highlights

Key activities in this theme include:

• Development of porous carbon materials with high surface area and controlled pore architecture for advanced supercapacitor electrodes.
• Surface engineering of carbon materials via heteroatom functionalization to improve electrochemical performance and stability.
• Fundamental studies of charge storage mechanisms and aging phenomena in supercapacitor systems.
