Solid state ionic conductors are important from an industrial viewpoint. A variety of such conductors have been found. In order to understand the reasons for high ionic conductivity in these solids, there have been a number of experimental, theoretical and computational studies in the literature. We provide here a survey of these investigations with focus on what is known and elaborate on issue...

The title compound, KSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates with the space group R[Formula: see text]. Its structure is constructed by very regular [with P-O distances ranging from 1.513 (6) to 1.522 (6) Å] PO(4) tetra-hedra and SnO(6) octa-hedra on the 3. axis, which are linked by O atoms, forming an [Sn(2)(PO(4))(3)] framework. The K atoms occupy the [Formula: see t...

Sodium super-ionic conductor (NASICON)-structured phosphates are emerging as rising stars cathodes for sodium-ion batteries. However, they usually suffer from a relatively low capacity due to the limited activated redox couples and intrinsic electronic conductivity. Herein, reduced graphene oxide supported NASICON Na3Cr0.5V1.5(PO4)3 cathode (VC/C-G) is designed, which displays ultrafast (up 50 ...

All-Solid-State Lithium Batteries (ASSLBs) are promising since they may enable the use of high potential materials as positive electrode and lithium metal negative electrode. This is only possible through solid electrolytes (SEs) stated large electrochemical stability window (ESW). Nevertheless, reported values for these ESWs very divergent in literature. Establishing a robust procedure to accu...
