Single-crystal X-ray structure analysis of the superionic conductor Li10GeP2S12.
Tetragonal Li10GeP2S12 (LGPS) is the best solid Li ion conductor known to date. So far, the structure of the electrolyte was only determined from powder diffraction and Rietveld refinement. Here, we present the first single-crystal structure analysis of the tetragonal LGPS structure. The reported structure is largely verified. However, an additional Li position is clearly identified which might...
متن کاملA new ultrafast superionic Li-conductor: ion dynamics in Li11Si2PS12 and comparison with other tetragonal LGPS-type electrolytes.
We report on a new ultrafast solid electrolyte of the composition Li11Si2PS12, which exhibits a higher room-temperature Li ion diffusivity than the present record holder Li10GeP2S12. We discuss the high-pressure synthesis and ion dynamics of tetragonal Li11Si2PS12, and comparison is made with our investigations of related members of the LMePS family, i.e. electrolytes of the general formula Li1...

The starting materials for the synthesis were Li2S (Alfa Aesar, 99.9 %), P (Alfa Aesar, 98.9 %), S (Alfa Aesar, 99.5%), and Sn (Alfa Aesar, 99.995%). The dry starting materials were first mechanically treated in a ball mill under argon for 2 days. Pellets were pressed from the obtained amorphous precursor and heated in an evacuated quartz ampoule according to the following temperature program: ...

Lithium disilicate nano-powders were synthesized via a mild condition hydrothermal reaction at 180 ºC for 48 and 72 h with a non stoichiometric1:2 Li:Si molar ratio in NaOH aqueous solution using Li2CO3 and SiO2.H2O as raw materials. The synthesized materials were characterized by powder X-ray diffraction (PXRD) technique and Fourier transform infrared (FTIR) spectroscopy. The XRD data showed t...
