An all-electric car with graphene-based battery to be unveiled at the 2017 Geneva Auto Show

Feb 15, 2017

One of the surprises about to be unveiled at the 2017 Geneva Auto Show is rumored to be a Chinese project - an all-electric vehicle by Pininfarina, being completed for Hybrid Kinetic Group (HK Motors of Hong Kong). The H600 luxury sedan is said to be relying on graphene-based battery technology to deliver high and lasting power.

While technical specifications and range are not yet available, the graphene battery in the sedan expected to launch soon should have around 50-100 times the power density of comparable lithium-ion batteries and 5-10 times the energy density.

A novel doping method could open the door to FLG use as transparent conducting electrodes

Feb 15, 2017

Researchers from King Abdullah University of Science and Technology (KAUST), in collaboration with the Georgia Institute of Technology, have recently demonstrated a simple, solution-based, method for surface doping of few-layer graphene (FLG) using novel dopants (metal-organic molecules) that show a minimal effect on the optical transmission as compared to other dopants like metal chlorides.

This work investigates the effect of dopant strength and dosage on the electronic and electrical transport properties of doped FLG. Moreover, It reveals fundamental differences between the doping results in single layer graphene and few-layer graphene. The study focused on few-layer CVD graphene, rather than single-layer CVD graphene, a somewhat less common area of research to date.

KAUST team uses laser scribing to create graphene electrodes for biosensors

Feb 15, 2017

Researchers at the King Abdullah University of Science and Technology (KAUST) have created graphene electrodes that function as effective biosensors, by using a laser inscribe patterns into a polymer sheet. The laser scribing technique locally heats parts of a flexible polyimide polymer to 2500 degrees Celsius or more to form carbonized patterns of patches on the surface that act as electrodes.

The black patches are about 33-micrometers thick, with a highly porous nature that allows molecules to permeate the material. Inside the patches, the graphene sheets have exposed edges that are effective at exchanging electrons with other molecules. "Graphene-based electrodes with more edge-plane sites are effectively better than those relying on carbon or carbon-oxygen sites in the plane of the material," said a member of the KAUST team.

Rice team's CNT-reinforced graphene foam is conductive and strong

Feb 14, 2017

Researchers at Rice University have constructed a graphene foam, reinforced by carbon nanotubes, that can support more than 3,000 times its own weight and bounce back to its original height. In addition, its shape and size are easily controlled - which the team demonstrated by creating a screw-shaped piece of the material.

The 3D structures were created from a powdered nickel catalyst, surfactant-wrapped multiwall nanotubes and sugar as a carbon source. The materials were mixed and the water evaporated; the resulting pellets were pressed into a steel die and then heated in a chemical vapor deposition furnace, which turned the available carbon into graphene. After further processing to remove remnants of nickel, the result was an all-carbon foam in the shape of the die, in this case a screw. The team said the method will be easy to scale up.

Directa Plus and Eurojersey jointly develop graphene-enhanced textiles

Feb 14, 2017

Directa Plus, a producer and supplier of graphene-based products for use in consumer and industrial markets, has teamed up with Eurojersey, an Italian producer of technical fabrics under its Sensitive Fabrics brand, to produce a range of fabrics containing the company’s graphene-based products. The new line will focus on high-performance technical fabrics targeting sportswear and underwear sectors.

The companies are conducting joint R&D to further develop the prototype textiles into product samples that will be marketed to the customers of Directa Plus and Eurojersey. The lamination of Sensitive Fabrics with Grafytherm functional membranes containing G+, distributed exclusively by Directa Textile Solutions, reportedly produces a technologically advanced fabric with unique thermal features: the presence of G+ graphene, which is highly thermally conductive, allows a homogeneous distribution of the heat produced by the human body in cold weather and a heat dispersion effect in hot weather.

Nippon Shokubai succeeds in mass production test of GO-based materials

Feb 13, 2017

Nippon Shokubai logo imageNippon Shokubai, a Japan-based globalal materials provider, has announced its success in mass production tests of graphene oxide-based materials. The production volume attained in the mass production test was reportedly improved dozens of times as much as that attained at laboratory, and Nippon Shokubai will start to provide graphene oxide-based materials as samples for application development.

The graphene oxide-based materials are lamellar carbon compounds with the approximately 1nm thickness and the company expects them to be suitable for various functional materials, such as lubricants, water treatment membranes, and catalysts. Nippon Shokubai stated that it has resolved various problems relating to chemical reactions of the production process and succeeded in the mass production test by utilizing its control technology for stable proceeding of chemical reactions in collaboration with Okayama University which retained academic knowledge about reaction mechanism of graphene oxide.

Skeleton Technologies receives a €15 million loan for graphene-based supercapacitors development

Feb 12, 2017

Skeleton Technologies logoSkeleton Technologies, developer and manufacturer of high energy and power density supercapacitors, has received €15 million in a loan from the European Investment Bank (EIB), under the European Fund for Strategic Investments (EFSI).

This funding is meant to allow the company to finance the R&D for the further development of its products and systems. Skeleton will use part of the money to invest in an electrode mass-production facility in Dresden, Germany, according to the statement. The loan is stated to be based on company performance and doesn’t dilute the holdings of Skeleton’s founders, according to the EIB.
