Source- This post on ‘Coconut Husk for supercapacitor fabrication‘ has been created based on the article ‘Carbon derived from coconut husks can power supercapacitors‘ published in ‘The Hindu’ on 01st July 2024
Why in News?
Researchers at the Government College for Women, Thiruvananthapuram, have devised a method to produce activated carbon. This activated carbon is suitable for supercapacitor fabrication. These activated carbon can be produced from coconut husks, which are a major agricultural residue in Kerala.
What is the significance
1. Immense potential for green Solutions- The coconut husk biowaste-derived activated carbon holds immense promise for sustainable and efficient green solutions for high-performance supercapacitors. This is due to their high availability, low cost, and eco-friendly nature.
2. Provides a material for Super capacitor development- This method provides another material in the mix for the search of an ideal supercapacitor electrode material.
3. Higher efficiency- The prototype supercapacitors made of coconut husk-derived activated carbon is found to be four-times more efficient than the existing supercapacitors.
