Electrical and Structural Properties of LiAlTi(PO)-Based Ceramics Prepared with the Addition of LiSiO.

The currently studied materials considered as potential candidates to be solid electrolytes for Li-ion batteries usually suffer from low total ionic conductivity. One of them, the NASICON-type ceramic of the chemical formula LiAlTi(PO), seems to be an appropriate material for the modification of its electrical properties due to its high bulk ionic conductivity of the order of 10 S∙cm. For this purpose, we propose an approach concerning modifying the grain boundary composition towards the higher conducting one.

BO-Doped LATP Glass-Ceramics Studied by X-ray Diffractometry and MAS NMR Spectroscopy Methods.

Two families of glasses in the LiO-AlO-BO-TiO-PO system were prepared via two different synthesis routes: melt-quenching and ball-milling. Subsequently, they were submitted to crystallization and yielded the LiA.Ti(PO) (LATP)-based glass-ceramics.
