Impact of the synthesis condition on solid electrolyte
Sulfide-based materials are currently under intense investigation for application as non- flammable electrolytes in solid state lithium batteries since the safety of the battery can be drastically enhanced with them. Unfortunately, solid electrolytes suffer from low ionic conductivity compared to the usual liquid electrolytes, and thus strategies to overcome this issue are examined by looking for alternative materials with different ratios of Li, P and S. Li3PS4 (75 Li2S-25 P2S5), a state of art sulfide-based solid electrolyte from the quasi-binary Li2S- P2S5 system was recently overcome by Li-Cl-P-S system, known to be among the most attractive sulfide-based solid electrolyte owing to its impressive ionic conductivity and its stability vs. Li metal anode. However, lot of impurities can be formed during synthesis at high temperature. We would like here to measure two samples synthesize in 2 different manners to check the crystallinity as the literature model seems to not fit properly to this phase.
