Redox-active supramolecular polymer binders derived from perylene bisimide nanowires enable high-rate lithium-sulfur batteries
Patent
·
OSTI ID:1651014
To address the need for multi-functional binders specifically tailored for sulfur cathodes π-stacked perylene bisimide (PBI) molecules are repurposed as redox-active supramolecular binders in sulfur cathodes for Li—S cells. In operando lithiation of PBI binders permanently reduces Li—S cell impedance enabling high-rate cycling, a critical step toward unlocking the full potential of Li—S batteries.
