## Title

- title: Chapter 24 Pulsed Field Gradient Nuclear Magnetic Resonance Measurement of
    Lithium Diffusion in Solid Electrolytes
  title_type: original
  lang: en

## Description

- description: Nuclear magnetic resonance (NMR) is a powerful technique for measuring
    atomic diffusion in lithium-ion conductors such as solid electrolytes and active
    materials. Since ion and electron fluxes inside the battery are governed by ion
    diffusion, the determination of the diffusion coefficient is essential. This section
    describes a method for determining the diffusion coefficient of a solid elec-trolyte
    using mainly pulsed field gradient (PFG) NMR. The diffusion coefficient of a perovskite
    solid electrolyte (Li0.29La0.57TiO3; LLTO) was determined. Tracer diffu-sion coefficient
    measured by isotope exchange and secondary ion mass spectrometry (SIMS) and conductivity
    diffusion coefficient measured by impedance spectroscopy were also applied for
    LLTO. PFG-NMR studies have revealed anisotropic diffusion of LLTO due to the two-dimensional
    crystal structure. SIMS studies show that grain boundary diffusion of LLTO is
    10,000 times slower than bulk diffusion. The Haven ratio was shown to be 0.24
    at the grain boundary compared to 1 in the bulk.
