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.
