Expanded graphite sheet hydrogen energy storage

TEG is a vermicular or a worm-like structured non-toxic layered material which exhibits good flexibility, high chemical tolerance and excellent thermal shock resistance.52–54 TEG (a multi-porous (2–10 nm) material) was synthesized by treating graphite55,56 with various ions and compounds (examples: sulphate. . Liu et al.94 synthesized TEG by a one-step room-temperature method which showed an expansion volume up to 225 times. This experiment was carried out using a binary-component. . TEG had also been used widely as a phase-changing material,66,138 fire retardant,139,140etc. due to its excellent thermal stability. Compared to graphene and CNTs, TEG is less expensive and easy to prepare. However,. [pdf]

FAQS about Expanded graphite sheet hydrogen energy storage

What is thermally expanded graphite?

Thermally expanded graphite (TEG) is a vermicular-structured carbon material that can be prepared by heating expandable graphite up to 1150 °C using a muffle or tubular furnace.

How to expand graphite sheets?

First, graphite flakes, KMnO 4, acetic anhydride, and perchloric acid were mixed in a ratio of 1 : 0.5 : 1 : 0.4 (g g −1) for a few seconds and the mixture was kept in a microwave oven at 360 W for 50 s to achieve the expansion of graphite sheets.

Are graphene sheets reversible?

The graphene sheets and TEG showed appreciable cycling stability with 90–95% of coulombic efficiency after the first cycle. The obtained reversible capacities of graphene sheets were 1130 and 636 mA h g −1 at a current density of 0.2 and 1 mA cm −2 which was higher than that of TEG and natural graphite.

Can graphite powders be continuously expanded and exfoliated to produce graphene?

Here we show that if graphite powders are contained and compressed within a permeable and expandable containment system, the graphite powders can be continuously intercalated, expanded, and exfoliated to produce graphene. Our data indicate both high yield (65%) and extraordinarily large lateral size (>30 μm) in the as-produced graphene.

How do you make graphene from graphite?

There are two large-quantity methods of producing graphene from graphite: (i) The oft-used modified Hummers’ method involves extensive oxidation 15, 16, but the resulting graphene oxide (GO) nanosheets are defect-laden and electrically insulating.

Is graphene yield scalable?

Our data indicate both high yield (65%) and extraordinarily large lateral size (>30 μm) in the as-produced graphene. We also show that this process is scalable and that graphene yield efficiency depends solely on reactor geometry, graphite compression, and electrolyte transport.
