  - Aqueous iodine based electrochemical energy storage is considered a potential
    candidate to improve sustainability and performance of current battery and supercapacitor
    technology. It harnesses the redox activity of iodide, iodine, and polyiodide
    species in the confined geometry of nanoporous carbon electrodes. However, current
    descriptions of the electrochemical reaction mechanism to interconvert these species
    are elusive. Here we show that electrochemical oxidation of iodide in nanoporous
    carbons forms persistent solid iodine deposits. Confinement slows down dissolution
    into triiodide and pentaiodide, responsible for otherwise significant self-discharge
    via shuttling. The main tools for these insights are in situ Raman spectroscopy
    and in situ small and wide-angle X-ray scattering (in situ SAXS/WAXS). In situ
    Raman confirms the reversible formation of triiodide and pentaiodide. In situ
    SAXS/WAXS indicates remarkable amounts of solid iodine deposited in the carbon
    nanopores. Combined with stochastic modeling, in situ SAXS allows quantifying
    the solid iodine volume fraction and visualizing the iodine structure on 3D lattice
    models at the sub-nanometer scale. Based on the derived mechanism, we demonstrate
    strategies for improved iodine pore filling capacity and prevention of self-discharge,
    applicable to hybrid supercapacitors and batteries.@eng
