DETAILED DESCRIPTION - The electrode comprises a porous support structure comprising pores, and particles comprising an electrode active material comprising an elemental sulfur (20 wt.%) contained within the pores. Each particles has a maximum cross-sectional dimension of 0.1-10 microns, and a total particle volume of 80% defined by the sum of each of the individual particle volumes, and defines a total quantity of particulate material (50%). Each pores has a total pore volume of 80% defined by the sum of each of the individual pore volumes, and cross-sectional diameters of 0.1-10 microns. A standard deviation of the maximum cross-sectional dimensions of the particles and the cross-sectional diameters of the pores is less than 50%. The porous support structure comprises an electrically conductive material that is deposited on the porous support structure, and porous continuous structure. The electrode active material occupies 10% of the accessible pore volume of the porous support structure. The maximum cross-sectional dimension of the porous continuous structure within the electrode is 50% of the maximum cross sectional dimension of the electrode. An electrochemical cell (10) comprises the electrode for: utilizing 100% of the 1672 mAh/g of sulfur in the cell through 10 charge and discharge cycles subsequent to a first charge and discharge cycle; and achieving a current density of 100 mA/g of sulfur in the electrode during 10 charge and discharge cycle subsequent a first charge and discharge cycle. The electrode has a void volume of 1 cm3/g of sulfur, a surface, a thickness and a cross-section perpendicular to the thickness, and contains less than 20 wt.% of binder. An area (50%) of the surface of the electrode defines a first, continuous area of uniform sulfur distribution with a first average concentration of sulfur. Any continuous area that covers 10% of the first, continuous area of the surface of the electrode includes a second average concentration of sulfur that varies by less than 25% relative to the first average concentration of sulfur across the first, continuous area. The cross-section (50%) of the electrode defines a first, continuous area of uniform sulfur distribution with a first average concentration of sulfur. Any continuous area that covers 10% of the first, continuous area of the cross-section includes a second average concentration of sulfur that varies by less than 25% relative to the first average concentration of sulfur across the a first, continuous area. A ratio of the average maximum cross-sectional dimension of the particles of material within the porous support structure to the average cross-sectional diameter of the pores within the porous support structure is 0.001:1-1:1. An INDEPENDENT CLAIM is included for an electrochemical cell.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of an electrochemical cell.
