Abstract
A cathode with one or more carbonaceous regions positioned adjacent to one another. At least one region includes carbonaceous particles, where each particle includes carbon fragments and a deformable perimeter that may coalesce with adjacent particles. At least one region may include aggregates, where each aggregate may be formed of several particles joined to one another. Pores may be interspersed throughout the aggregates. At least one region may include agglomerates, where each agglomerate may be formed of a multitude of the aggregates joined to one other. At least one region has an electrical conductivity in an approximate range between 500 S/m to 20,000 S/m at a pressure of 12,000 pounds per square in (psi).
