title: Lithium polysulfidophosphates: a family of lithium-conducting sulfur-rich compounds for lithium-sulfur batteries.
abstract: Sulfur-rich lithium polysulfidophosphates (LPSPs) act as an enabler for long-lasting and efficient lithium-sulfur batteries. LPSPs have ionic conductivities of 3.0×10(-5)  S cm(-1) at 25 °C, which is 8 orders of magnitude higher than that of Li2S. The high lithium ion conductivity imparts excellent cycling performance, and the batteries are configured in an all-solid state, which promises safe cycling with metallic lithium anodes.
