6 FAQs about [Graphite flake size determines energy storage]
What is the maximum expansion ratio of graphite flakes?
The graphite flakes with −10 mesh size showed a maximum expansion ratio (80 ml g −1) at 1150 °C. TEG with an expansion ratio of ∼400 ml g −1 was achieved at 1150 °C using commercial expandable graphite (with +50 mesh, >300 μm) in a closed lid crucible (Table 2).
Does graphite flake size affect the expansion ratio of Teg?
They found that the graphite flake size had an effect on the expansion ratio of TEG. For example, when graphite flakes with a +325 mesh (>44 μm) size range were used to prepare TEG, they obtained a low intercalation rate because of the small size of the flakes which led to a poor expansion ratio.
