Figure 1. Design Strategy for Trigonal Chloride Solid Electrolytes

Caption

The arrangement of metal ions (yttrium in this case) within each layer affects the ionic conductivity. To ensure the unobstructed movement of lithium ions, the number of metal ions occupying available sites within each layer should be less than 0.444. Furthermore, to create a sufficiently wide pathway for lithium ions within each layer, the occupancy of metal ions should be more than 0.167. Therefore, achieving an occupancy of metal ions between 0.167 and 0.444 within each layer results in a conductive layer with high ionic conductivity.
