title: Mapping spatially inhomogeneous electrochemical reactions in battery electrodes using high energy X-rays.
abstract: The spatial distribution of a reaction through a lithium-ion battery electrode has been resolved using micro-beam high-energy X-ray scattering measurements coupled with Pair Distribution Function (PDF) analysis. The electrochemical reaction was most advanced at the interface between the electrode and electrolyte-soaked separator, with linear variation in reaction progress with distance from this interface.
