New graphene hybrid material could open the door to highly efficient supercapacitors

A research team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM), has developed a highly efficient supercapacitor based on a novel, powerful and sustainable graphene hybrid material that reportedly has comparable performance data to currently utilized batteries.

A common problem with supercapacitors to date was their lack of energy density. While lithium accumulators reach an energy density of up to 265 Kilowatt hours (KW/h), supercapacitors thus far have only been able to deliver a fraction of that. The team working with TUM's Roland Fischer has now developed a novel, powerful as well as sustainable graphene hybrid material for supercapacitors. It serves as the positive electrode in the energy storage device. The researchers are combining it with a proven negative electrode based on titan and carbon.

Several graphene companies stocks are on the rise, is that a positive sign for the industry?

2020 was a surprisingly good year for many graphene investors, and many stocks saw positive returns. We are following over 15 public graphene companies, and the share price of many of them appreciated nicely, especially in the last few months:

The company is a senior advisor for consumer and commercial AI at Google X. Following is an interview with Ramesh to discuss GraphAudio's technology, business and roadmap.

Orbex secures $24 million funding for its graphene-enhanced rocket

Orbex, a UK-based private, low-cost orbital launch services company, recently reported that it has secured $24 million in a funding round led by BGF (London) and Octopus Ventures (London). At the beginning of 2020, Orbex developed what it calls an "advanced, low carbon, high performance micro-launch" rocket called "Orbex Prime".

The new investments secure the roadmap to the first launch of Orbex’s vertical launch vehicle, Orbex Prime, from the Space Hub Sutherland spaceport in Scotland. Incorporating a wide range of advanced materials for its development, the launch vehicle boasts a 3D-printed rocket engine manufactured in a single piece without joins in partnership with additive manufacturer SLM Solutions (Lübeck, Germany). The vehicle is also built out of graphene-enhanced carbon fiber composites for the main structures and tanks.

A hands-on (foot-on) review of SpaceBlue's graphene-enhanced recycled rubber floor mat

A couple of months ago UK-based SpaceBlue launched a graphene-enhanced flooring product called SpaceMat. The company sent us a floor mat for review here at Graphene-Info.

Reviewing a floor mat isn't easy - there's not much to do with it, so we decided to use it in our home for a few months - and let nature and our family of six (plus a husky) do its thing. One of the promises of the SpaceMat is its enhanced durability, and we definitely put that to the test.

Zen Graphene Solutions develops graphene-based potential treatment for bacterial and viral Infections
