Unraveling the Reversible Redox Mechanism of Li6PS5Cl Solid Electrolyte in All-Solid-State Lithium-Sulfur Batteries

We reveal the reversible redox mechanism of Li6PS5Cl in composite cathodes for practical all-solid-state lithium-sulfur batteries. The limited electrochemical reactivity of the non-conducting sulfur-based active material induces the formation of...
