▎ 摘　　要

NOVELTY - An energy storage device comprises a molecular capacitor with very high energy density, denominated as a molecular hyper capacitor containing at least one cell having a positive and a negative electrode (c), and an electrolyte (d). The energy storage device contains at least one modified electrode is formed by a composite, that mix an electric conductive material with a self-assembled molecular film or coupled in a chemical or physical way by redox active molecules. USE - Energy storage device e.g. capacitor, electrochemical capacitors, ultra-capacitors and supercapacitors. ADVANTAGE - The energy storage device is inexpensive, has high energy density and has long life based on charge and discharge cycles and fast charging and discharging regimes. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of hyper capacitive electrochemical cell. Electrodes (c) Electrolyte (d) Electrical insulator (e) Mesoscopic interfaces (h) Impurities (j)
