Functionalization of petroleum coke-based mesoporous carbon for synergistically enhanced capacitive performance

Abstract

Abstract

A new double layer super-capacitor made by free-standing activated carbon membranes and highly concentrated potassium acetate solutions

“…These materials are often treated at high temperatures, often with chemical agents, to further develop their porosity. Carbonaceous materials for EDLCs can be classified as nanostructured carbons (micro or nanotubes) [4] or active carbons (ACs) [3,[5][6][7][8]. Despite their excellent performances, nanostructured carbons are still expensive and difficult to prepare.…”

“…In contrast, activated carbons are commonly used in commercial devices thanks to their economical price and easy preparation routes. ACs can be obtained as by-product in industrial processes [8] or by biomasses waste [9][10], making them examples of circular economy materials.…”
