Untreated Natural Graphite as a Graphene Source for High-Performance Li-Ion Batteries

Batteries, 2018
Graphene nanosheets (GNS) are synthesized from untreated natural graphite (NG) for use as electroactive materials in Li-ion batteries (LIBs), which avoids the pollution-generating steps of purifying graphite.

Compaction of Natural Graphite

TANSO, 1968
Three broad types of natural graphites are recognized: flake, vein, and amorphous. The compaction of graphite powders, representing these types, into coherent binderless artifacts at room temperature and pressures up to 125, 000 psi has been studied.

Compression behavior of natural graphite sheet [PDF]

SN Applied Sciences, 2020
The compression behavior of natural graphite sheet (NGS) is studied during the forming process and during the compression of finished sheets. The forming process, in which the low-density semi-finished NGS is compressed to higher densities, is quantified by the proposed relationship ...
