Abstract
This chapter describes the use of pair distribution function (PDF) analysis for understanding the local structure of sodium-ion battery materials, explaining how PDFs are obtained for battery materials and presenting a number of case studies where PDF has improved understanding of solid sodium-ion battery electrode materials and liquid electrolytes. Coherent scattering is made up of Bragg scattering and diffuse scattering. Bragg scattering occurs when parallel diffracted beams interfere constructively as a consequence of long-range ordering in the material. Two main strategies exist for collecting PDF data on battery materials: ex situ and in situ measurements. PDF, alongside Raman spectroscopy and/or small-angle scattering, can give useful structural information about hard carbons. Tin has attracted significant attention as an anode material as its theoretical capacity for sodium storage is among the highest known.
