Nontrivial Effects of “Trivial” Parameters on the Performance of Lithium–Sulfur Batteries

Batteries, 2018
A robust lithium-sulfur (Li–S) battery is constituted by a wide range of optimized fundamental parameters (e.g., amount of electrolyte, electrolyte additive, sulfur loading density, and the size of sulfur particles). In this paper, some other often-
