  bibo_abstract:
  - Redox mediators could catalyse otherwise slow and energy-inefficient cycling of
    Li-S and Li-O 2 batteries by shuttling electrons/holes between the electrode and
    the solid insulating storage materials. For mediators to work efficiently they
    need to oxidize the solid with fast kinetics yet the lowest possible overpotential.
    Here, we found that when the redox potentials of mediators are tuned via, e.g.,
    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 mediators 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 requires therefore carefully considering
    the surface conditions of the storage materials and electrolyte-dependent redox
    potentials, which may be tuned by salt concentrations or solvents.@eng
