Science Daily  April 18, 2024 The difficulty in characterizing the complex structures of nanoporous carbon electrodes has led to a lack of clear design principles with which to improve supercapacitors. Charge is stored within the porous carbon structure, and pore size has thus long been viewed as the key factor for determining storage capacity. An international team of researchers (UK, France) evaluated commercial nanoporous carbons and did not find a correlation between pore size and capacitance. Rather, their combination of simulations and data measurements indicated that the key factor was the extent of disorder, as smaller graphene-like domains could more […]
