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