## Description

- description: 'The lithium-ion transport mechanism in 0.7Li(CB9H10)–0.3Li(CB11H12)
    complex hydride solid electrolyte was studied over a wide time-scale (ns‒ms) by
    choosing appropriate techniques for assessing ionic motion on the desired time-scale
    using nuclear magnetic resonance (NMR) relaxation, AC impedance, and pulsed field
    gradient-NMR (PFG-NMR) measurements. The 7Li NMR linewidth decreased with increasing
    temperature, and the spin-lattice relaxation time T1 for the cation and anions
    showed a minimum near 303 K, indicating that the lithium ions and the anions were
    highly mobile. The activation energy estimated from the analysis of the NMR relaxation
    time matched well with the values estimated from the AC impedance and PFG-NMR.
    This confirms that the lithium-ion motion in 0.7Li(CB9H10)–0.3Li(CB11H12) is the
    same over a wide time-scale, suggesting steady Li-ion motion over a wide transport
    range. This understanding offers insights into strategies for designing complex
    hydride lithium superionic conductors. '
