  text: Nowadays commercial supercapacitors are based on purely capacitive storage
    at the porous carbons that are used for the electrodes. However, the limits that
    capacitive storage imposes on energy density calls to investigate new materials
    to improve the capacitance of the device. This new type of electrodes (e.g., RuO2,
    MnO2…) involves pseudo-capacitive faradaic redox processes with the solid material.
    Ion exchange with solid materials is, however, much slower than the adsorption
    process in capacitive storage and inevitably leads to significant loss of power.
    Faradaic process in the liquid state, in contrast can be similarly fast as capacitive
    processes due to the fast ion transport. Designing new devices with liquid like
    dynamics and improved specific capacitance is challenging. We present a new approach
    to increase the specific capacitance using biredox ionic liquids, where redox
    moieties are tethered to the electrolyte ions, allowing high redox concentrations
    and significant pseudo-capacitive storage in the liquid state. Anions and cations
    are functionalized with anthraquinone (AQ) and 2,2,6,6-tetramethylpiperidinyl-1-oxyl
    (TEMPO) moieties, respectively. Glassy carbon, carbon-onion, and commercial activated
    carbon electrodes that exhibit different double layer structures and thus different
    diffusion dynamics were used to simultaneously study the electrochemical response
    of biredox ionic liquids at the positive and negative electrode.
