Superionic conductors are materials that provide fast ion conduction similar to liquid electrolytes, and are currently investigated for the use in solid-state batteries. The usage of a solid electrolyte instead of a liquid electrolyte is thought to provide more safety as solids are much less prone to flammability. However, there is still need for novel ionic conductors and a more in-depth understanding of ionic transport in solids is necessary. The proposal is based on a novel ionic conductor of sodium ions in the solid state, NaTi2(PS4)3, in which the underlying reasons for the ionic conductivity are yet unknown. The hypothesis of this proposal is that structural changes can be induced in this material to gain a better fundamental understanding of the ionic transport, while leading to a material with higher ionic conductivities.

超离子导体是提供类似于液体电解质的快速离子传导的材料，目前正在研究在固态电池中的使用。使用固体电解质代替液体电解质被认为可以提供更高的安全性，因为固体不易燃。然而，仍然需要新型离子导体，并且需要更深入地了解固体中的离子传输。该提案基于固态钠离子的新型离子导体NaTi2(PS4)3，其中离子导电性的根本原因尚不清楚。该提案的假设是，可以在该材料中引起结构变化，以获得对离子传输更好的基本理解，同时产生具有更高离子电导率的材料。
