Abstract
A composition of matter suitable for incorporation into a battery electrode is disclosed. In some implementations, the composition of matter may include pores that may be defined in size or shape by several carbonaceous particles. Each of the particles may have multiple regions such that adjacent regions are separated from each other by some of the pores. Deformable regions may be distributed throughout a perimeter of each of the particles, for example, to accommodate coalescence of multiple adjacent particles. The composition of matter may also include a plurality of aggregates and a plurality of agglomerates, where each aggregate includes a multitude of the particles joined together, and each agglomerate includes a multitude of the aggregates joined together.
