Diffraction studies on fluorite-type superionic conductors.

Li-rich antiperovskite superionic conductors based on cluster ions.

Enjoying great safety, high power, and high energy densities, all-solid-state batteries play a key role in the next generation energy storage devices. However, their development is limited by the lack of solid electrolyte materials that can reach the practically useful conductivities of 10-2 S/cm at room temperature (RT). Here, by exploring a set of lithium-rich antiperovskites composed of clus...

Aqueous Stability of Alkali Superionic Conductors from First-Principles Calculations

Ceramic alkali superionic conductor solid electrolytes (SICEs) play a prominent role in the development of rechargeable alkali-ion batteries, ranging from replacement of organic electrolytes to being used as separators in aqueous batteries. The aqueous stability of SICEs is an important property in determining their applicability in various roles. In this work, we analyze the aqueous stability ...

Neutron diffraction and atomistic simulation studies of Mg doped apatite-type oxide ion conductors.

In this paper, detailed studies of the effect of Mg doping in the apatite-type oxide ion conductor La9.33Si6O26 are reported. Mg is confirmed as an ambisite dopant, capable of substituting for both La and Si, depending on the starting composition. A large enhancement in the conductivity is observed for Si site substitution, with a reduction for substitution on the La site. Neutron powder diffra...
