Claim 1:
2. The process of claim 1, wherein:
the graphenic structures, coalesced graphenic layer, higher-layer graphenic regions, and perimorphic wall formed over the templating surface of each template particle comprise carbon; and
a powder of the perimorphic composite particles before being heated to the second temperature comprises a first 532-nm Raman spectrum having:
an unfitted D peak between 1300 cm−1 and 1332 cm−1; and
an unfitted G peak between 1580 cm−1 and 1612 cm−1; and

an interpeak interval between the unfitted D and G peaks of at least 260 cm−1; and
a peak intensity ratio ID/IG of at most 1.5; and
a peak intensity ratio I2D/IG is at most 0.2; and
a powder of the perimorphic composite particles after being heated to the second temperature comprises a second 532-nm Raman spectrum having:
an unfitted D peak between 1340 cm−1 and 1375 cm−1 and at least 8 cm−1 higher than the unfitted D peak of the first 532-nm Raman spectrum; and
an unfitted G peak between 1580 cm−1 and 1612 cm−1; and
an interpeak interval between the unfitted D and G peaks of at most 250 cm−1; and
a peak intensity ratio ID/IG of at most 1.5; and
a peak intensity ratio I2D/IG is at most 0.2; and
the first and second 532-nm Raman spectra are each an average spectrum, where each average spectrum is produced by averaging 16 point spectra generated by raster scanning under 532 nm excitation.
