Dataset of pressurized physically activated carbon as a cathode host material for lithium–sulfur batteries

This dataset comprehensively provided experimental data that characterized and evaluated the pore-structure features of pressurized physically activated carbon and its performance in lithium–sulfur batteries. The dataset included nitrogen adsorption–desorption isotherms and TGA data of the prepared materials, as well as electrochemical characterization data, including CV, EIS, and galvanostatic charge–discharge measurements, for evaluating lithium–sulfur battery cathodes.
