For all solid-state batteries solid lithium ion conductors are indispensable. Phosphide-based materials, which act as solid electrolytes, were expanded by the investigation of the new material class of phosphidotrielates. The materials were fully characterized including X-ray, neutron, NMR, Impedance, Raman, and computational methods. Additionally to a boosting of the ionic conductivity compared to phosphidotetrelates, the detailed analysis of the structures and the properties of phosphidotrielates leads to a novel superionic conductor and general insights into the structure factors, which drive or hinder ionic mobility.
