Flat vs. Crumpled. Graphene For Energy Storage Applications (Graphene USA 2016)

Raymor's plasma process enables to synthesize graphene nanoflakes in kg quantities using a gas-phase and substrate-free approach. The resulting material consists of very thin, crumpled or wavy nanoflakes, and displays very high graphitization, resulting in a Raman signature very close to that of monolayer CVD graphene. The high electrical conductivity combined to this unique morphology offers distinctive advantages in certain energy storage applications, specifically to protect silicon nanoparticles in LIB anodes.

Dr. Jens Kroeger is the CTO of Raymor and NanoIntegris. After his PhD in physics at McGill, he joined Raymor as an NSERC postdoctoral fellow in 2010. Under his leadership, Raymor implemented a large scale nanotube production technology developed by Canadian research institutions and developed a large-scale graphene production method. Jens Kroeger is a member of a CSA Technical Committee developing the ISO standard for nanomaterials safety datasheets. Dr. Kroeger has published over 20 peer-reviewed scientific articles and technical reports.

Raymor, together with its Nanointegris and Graphene Limited Partnership subsidiaries, is a world leading provider of high-purity crumpled graphene nanoplatelets (GNP) and

small diameter single-wall carbon nanotubes (SWCNT).

 

Established in 2006, Raymor uses a patented plasma technology to synthesize both GNP and SWCNT at industrial scale and with superior quality.

 

The small diameter SWCNT (<1.5 nm) are separated and purified to create formulations of conductive and semiconducting inks for electronic applications. Our PureWave Graphene (few layers thick <10), with a unique crumpled morphology, is ideally suited to enclose silicon nanoparticles for graphene-Si battery anodes.
