Gluing Carbon Black and Sulfur at Nanoscale: A Polydopamine‐Based “Nano‐Binder” for Double‐Shelled Sulfur Cathodes

A Polydopamine-based “nano-binder”, which can glue carbon and sulfur at nanoscale, is used to construct stable double-shelled sulfur cathodes. This unique hierarchical design for S cathode can not only offer a physical barrier for trapping polysulfides, but also prevent conducting carbon black from detaching to cathode surface. Polydopamine with high elasticity and excellent isotropy can prevent the cathode from deformation.
