Grab your coat…: Polypyrrole can be doped with polyethylene glycol and then coated onto the surface of sulfur/aligned carbon nanotubes to produces a composite cathode material for Li/S batteries. The battery can work at a very high current density, and the cathode exhibits a high initial specific capacity and sulfur usage. A high reversible capacity is also retained after 100 cycles.
