Novel Polyaniline–Silver–Sulfur Nanotube Composite as Cathode Material for Lithium–Sulfur Battery

The preparation and characterization of a polyaniline–silver–sulfur nanotube composite were reported in this paper. The polyaniline–silver nanotube composite was synthesized via an oxidation-reduction method in the sodium dodecyl sulfate (SDS) solution. After being vulcanized, the polyaniline–silver...
