A conductive, elastic, electroactive binder composed of polypyrrole and polyurethane is adopted for flexible, high‐loading lithium–sulfur cathodes. The conductivity of the polypyrrole helps mitigate the negative effects of insulating sulfur, and the elastomeric matrix accommodates sulfur volume expansion. The binder is used with a simple carbon/sulfur composite to produce high‐performance, flexible electrodes without excessive carbon, interlayers, or special additives.
