Query: Reciprocal Space Imaging of Ionic Correlations in Intercalation
  Compounds   The intercalation of alkali ions into layered materials has played an
essential role in battery technology since the development of the first
lithium-ion electrodes. Coulomb repulsion between the intercalants leads to
ordering of the intercalant sublattice, which hinders ionic diffusion and
impacts battery performance. While conventional diffraction can identify the
long-range order that can occur at discrete intercalant concentrations during
the charging cycle, it cannot determine short-range order at other
concentrations that also disrupt ionic mobility. In this article, we show that
the use of real-space transforms of single crystal diffuse scattering, measured
with high-energy synchrotron x-rays, allows a model-independent measurement of
the temperature dependence of the length scale of ionic correlations along each
of the crystallographic axes in a sodium-intercalated V$_2$O$_5$. The
techniques described here provide a new way of probing the evolution of
structural ordering in crystalline materials.
