Ex Situ 23Na Solid-State NMR Reveals the Local Na-Ion Distribution in Carbon-Coated Na2FePO4F during Electrochemical Cycling

Autor: Danielle L. Smiley, Gillian R. Goward

Publikováno v: Chemistry of Materials. 28:7645-7656

The potential Na-ion cathode material Na2FePO4F is investigated here by ex situ 23Na solid-state nuclear magnetic resonance (ssNMR) in order to characterize the structure and ion mobility as a function of electrochemical cycling. The use of fast magi

An Unexpected Pathway: 6Li-Exchange NMR Spectroscopy Points to Vacancy-Driven Out-of-Plane Li-Ion Hopping in Crystalline Li2SnO3

Autor: Alex D. Bain, Gillian R. Goward, Danielle L. Smiley, Martin Wilkening, Julia Langer

Publikováno v: The Journal of Physical Chemistry C. 120:3130-3138

The development and engineering of new materials for modern electrochemical energy-storage systems requires an in-depth understanding of Li-ion dynamics, not only on the macroscopic length scale but also from an atomic-scale point of view. Hence, the
