Lithium-sulfur batteries (LSBs) are known to be potential next-generation energy storage devices. Recently, our group reported an LSB cathode made using sulfur spheres that has been spherically templated by MXene nanosheets decorated with CoSe2 nanoparticles, forming a "loose-templating" configuration. It was postulated the minimal restacking of outer nanoparticle-decorated layer helps enable facile ionic transport. However, as do not adhere conformally internal sphere's surface, such configuration can controversial, thus requiring more systematic understanding. In this work, we report and quantify for first time independent dependent variables involved in morphology, allowing us identify having smaller nanoparticles resulted better Li+ ion transport enhanced electrochemical performances. The optimized structure exhibited initial specific capacity 1274 mAh/g 0.06% decay rate per cycle at 0.5 C over 1000 cycles LSBs.
