Fluorinated quinone derived organosulfur copolymer cathodes for long-cycling, thermostable and flexible lithium–sulfur batteries

Organosulfur copolymers are promising cathode materials in lithium–sulfur batteries because of adjustable molecular structure, tunable electrochemical properties and excellent processability. However, conventional organosulfur copolymers suffer from poor electronic/ionic conductivity and low sulfur content, which limit rate capability and energy density. Herein, fluorinated quinone-derived organics are copolymerized with sulfur via convenient...
