Graphene-Info: the graphene experts

MIT researchers have gained new understanding of what leads electrons to split into fractions of themselves. Their solution sheds light on the conditions that give rise to exotic electronic states in graphene and other two-dimensional systems.

The recent work attempts to make sense of a discovery that was reported earlier this year by a different group of physicists at MIT, led by Assistant Professor Long Ju. Ju’s team found that electrons appear to exhibit “fractional charge” in pentalayer graphene — a configuration of five graphene layers that are stacked atop a similarly structured sheet of boron nitride.

Researchers at the California Institute of Technology (Caltech) have developed a method for coating lithium-ion battery cathodes with graphene, extending their life and performance. This recent effort may improve lithium-ion battery performance and reduce reliance on cobalt, an element frequently used in lithium-ion batteries that is difficult to source sustainably.

Caltech senior research scientist, David Boyd, has worked over the past decade to develop techniques for manufacturing graphene. In 2015, Boyd and colleagues discovered that high-quality graphene could be produced at room temperature. Prior to this, the production of graphene required extremely high temperatures, up to 1,000 degrees Celsius. After this breakthrough, they searched for new applications for graphene. Recently, Boyd teamed up with Will West, a technologist at Caltech's Jet Propulsion Laboratory (JPL), which Caltech manages for NASA. West specializes in electrochemistry and, in particular, in the development of improved battery technologies. Boyd and West set out to see if graphene could create an improved lithium-ion battery, which they have shown to be possible.

Graphene Manufacturing Group (GMG) has announced the launch of SUPER G®, a graphene slurry which can be used to enhance the performance of lithium-ion batteries. This product has, according to GMG, the potential to reshape the future of energy storage, offering battery manufacturers an innovative solution that optimizes efficiency, power, and longevity.

SUPER G® is a graphene slurry which has been developed by GMG over the last 3 years for GMG’s own Graphene Aluminum-Ion Battery which has unique properties of high electrical conductivity, low charge transfer resistance and high density compared to other carbon battery additives and materials used in lithium-ion batteries.

HydroGraph Clean Power, a sustainable commercial manufacturer of graphene, has announced that it has received a purchase order from a major global automotive company for research quantities of four additional graphene products. The purchase order includes both pristine functionalizations and completely novel formulations produced by HydroGraph’s patented explosion synthesis process.

The new purchase order is an expansion of the ongoing automotive composite improvement program which began with the customer earlier in 2024, adding new graphene projects in advanced manufacturing applications.

G6 Materials has announced it will cease all revenue generating activities due to legal hardships, an inability to raise capital, insolvency issues and an impending failure to file cease trade order to be issued by the British Columbia Securities Commission.

The Company will cease operations at its Ronkonkoma, NY facility following an eviction notice from the landlord due to significant unpaid rent. The Company maintains the Graphene Supermarket and Breathe Plus digital assets and will look to develop opportunities within these avenues for revenue generation. The Company is currently assessing its situation to determine the next steps.
