Impact of Carbon Porosity on Sulfur Conversion in Li?S Battery Cathodes in a Sparingly Polysulfide Solvating Electrolyte

Advancing the development of lithium-sulfur (Li?S) technology is advantageous for next generation secondary batteries to improve gravimetric and volumetric energy established storage devices. In this regard, a sparingly PS solvating electrolyte based on sulfolane hydrofluoroether known as promising concept enhance density by increasing cycling stability. So far, little about impact carbon porosity electrochemical sulfur utilization. Herein, materials with varying pore diameter architecture (micropores, mesopores hierarchical pores) are studied scaffold Li?S cathodes using TMS/TTE obtain more insights into relationship between modified conversion mechanism electrolytes. The evaluation under lean conditions (5 ?l mgS?1) revealed stable performance all cathodes. Using microporous electrodes, reversible quasi-solid-state detected an additional third discharge plateau being confirmed cyclovoltammetry. GITT experiments give evidence that impacts reaction kinetics polysulfide electrolyte. Based these findings, new mechanistic operation provided
