Ionic conductivity of Li₃PS₄ was enhanced by the two ways: quenching method and addition of Li₃PO₄. The quenching method froze its high-temperature phase partially down to room temperature and increased its ionic conductivity by three times. Addition of Li₃PO₄ resulted in the formation of a new metastable phase, the composition of which was considered to be around 0.25Li ₃PO₄-0.75Li₃PS₄. Its conductivity at room temperature was 7.3 × 10^{- 5} S cm^{- 1}, which was about 100 times higher than that of Li₃PS₄.
