Polyphenyl polysulfide: a new polymer cathode material for Li–S batteries?

Chemical Communications Pub Date: 2019-03-28 DOI: 10.1039/C9CC01495K

Abstract

We report a new class of polyphenyl polysulfides synthesized by condensation reactions between 4,4′-thiobisbenzenethiol (TBBT) and sulfur with four different molar ratios in a toluene/carbon disulfide mixture at room temperature. Through comprehensive material and electrochemical characterization, we found that they have great application potential for Li–S batteries.
