Cathode porosity is a missing key parameter to optimize lithium-sulfur battery energy density

For high-energy lithium-sulfur batteries, a dense electrode with low porosity is desired to minimize electrolyte intake, parasitic weight, and cost. Here the authors show the impact of porosity on the performance of lithium-sulfur batteries and reveal the mechanism through analytical modeling.
