  bibo_abstract:
  - Redox mediators could catalyse otherwise slow and energy-inefficient cycling of
    Li–S and Li–O2 batteries by shuttling electrons or holes between the electrode
    and the solid insulating storage materials. For mediators to work efficiently
    they need to oxidize the solid with fast kinetics but with the lowest possible
    overpotential. However, the dependence of kinetics and overpotential is unclear,
    which hinders informed improvement. Here, we find that when the redox potentials
    of mediators are tuned via, for example, Li+ concentration in the electrolyte,
    they exhibit distinct threshold potentials, where the kinetics accelerate several-fold
    within a range as small as 10 mV. This phenomenon is independent of types of mediator
    and electrolyte. The acceleration originates from the overpotentials required
    to activate fast Li+/e− extraction and the following chemical step at specific
    abundant surface facets. Efficient redox catalysis at insulating solids therefore
    requires careful consideration of the surface conditions of the storage materials
    and electrolyte-dependent redox potentials, which may be tuned by salt concentrations
    or solvents.@eng
