In a recent study published in the Journal of Materials Chemistry A, an international research team investigates sodium-ion diffusion in NASICON-based solid-state electrolytes — promising candidates for next-generation solid-state batteries. Using quasielastic neutron scattering (QENS) and X-ray diffraction (XRD), the researchers identify two distinct Na⁺ diffusion processes occurring on different time and length scales.
