Fluorinated graphene/sulfur hybrid cathode for high energy and high power density lithium primary batteries.

ABSTRACT: It is a great challenge to obtain high performance carbon fluoride (CF _x ) cathodes with high specific capacity and good rate performance due to the electronic conductivity of CF _x being known to decrease with an increase in the specific capacity. Herein, we propose a novel fluorinated graphene (FG)/sulfur hybrid cathode to enhance both the energy density and power density of lithium/carbon fluoride (Li/CF _x ) batteries. Impressive enhancements of the specific capacity, discharge voltage, and rate capability are demonstrated with the novel FG/sulfur hybrid cathode. In comparison with the pristine FG cathode, the hybrid cathode exhibits higher electrochemical activity, lower overpotential, and faster ion transfer over the main discharge
