  We present spectroscopic neutron imaging (SNI), a bridge between imaging and
scattering techniques, for the analysis of hydrogenated molecules in
lithium-ion cells. The scattering information of CHn-based organic solvents and
electrolytes was mapped in two-dimensional space by investigating the
wavelength-dependent property of hydrogen atoms through time-of-flight imaging.
Our investigation demonstrates a novel approach to detect physical and chemical
changes in hydrogenated liquids, which extends, but not limits, the use of SNI
to relevant applications in electrochemical devices, e.g., the study of
electrolytes in Li-ion batteries.
