A solid lithium superionic conductor Li11AlP2S12 with a thio-LISICON analogous structure has been synthesized for the first time by sintering at 500 °C (LAlPS500). Such a pure lithium ionic conductor shows a conductivity of 8.02 × 10(-4) S cm(-1) at 25 °C, a low Ea of 25.4 kJ mol(-1), and a wide electrochemical voltage window of higher than 5.0 V (vs. Li(+)/Li). This facilitation of Li ionic conduction suggests the potential application in solid lithium ion batteries.
首次通过在500℃下烧结合成了具有硫代-LISICON类似结构的固态锂超离子导体Li11AlP2S12（LAlPS500）。这种纯锂离子导体在25℃时的电导率为8.02×10(-4) S cm(-1)，低活化能为25.4 kJ mol(-1)，电化学电压窗口宽于5.0 V（相对于Li(+)/Li）。这种锂离子传导的促进表明其在固态锂离子电池中的潜在应用。
