Effect of the Layer Height on the Electrochemical Properties of Lithium-Sulfur Cell

One of the possible ways of manufacturing high-energy density lithium-sulfur batteries is to increase the height of the active material layer and thus increase the thickness of the electrode. The energy density frequently rises in tandem with the height of the active material layer; however, increased electrode thickness might result in a variety of negative consequences such as increased internal resistance of the cell, increased cell polarization, decreased porosity, or insufficient ion diffusion. The effect of the layer height of the positive electrode on the rate capability, energy density, and cycling behavior of the lithium-sulfur cells will be analyzed in this article.
