Toward the Theoretical Capacitance of RuO_2 Reinforced by Highly Conductive Nanoporous Gold

摘要

The growing demand for sustainable and renewable green energy has stimulated extensive research into developing high-performance energy-storage and conversion devices that are primarily batteries, fuel cells, and supercapacitors. Super-capacitors, also known as ultracapacitors or electrochemical capacitors, have higher power density and longer cycle life but much lower energy density than batteries and fuel cells.
