Q. Recently, researchers from which state have developed a method to produce activated carbon for supercapacitors from coconut husks?
Answer: Kerala
Notes: Researchers at Government College for Women, Thiruvananthapuram, Kerala developed a method to produce activated carbon from coconut husks for supercapacitors. This sustainable, efficient solution leverages the high surface area of activated carbon, making it ideal for high-performance supercapacitors. These devices store and deliver charge through reversible adsorption and desorption of ions, enhancing electrochemical energy storage.
