The Chinese CRRC develops graphene supercapacitors for public transportation

Oct 12, 2015

The CRRC, the Chinese state owned rolling stock manufacturer and the world's largest train builder, has developed graphene-based supercapacitors that can power electric buses with higher efficiency and for a longer period. 

The CRRC has reportedly produced two types of capacitors, a 2.8 Volt/30,000 F capacitor and 3 Volt/12,000 F one. The former is said to be able to power trolley buses for up to 10 km after a one-minute charge, compared with 6 km in the previous generation. The latter one can provide enough electricity to power a tram for 6 km with only 30 seconds of charging.In addition to improvements in performance, the new products are also more energy-saving and environmentally friendly. 

Skeleton Technologies' graphene supercapacitors to power Estonian unmanned ground vehicle

Sep 15, 2015

Skeleton Technologies is to supply graphene-based supercapacitors to Milrem's multipurpose UGV (unmanned ground vehicle) to be showcased at DSEI 2015. Milrem (Military Repair, Engineering and Maintenance) is an Estonian company whose mission is to be a partner in the defence and security sector, offering flexible product development solutions and full life cycle support for heavy vehicles. Milrem is also developing a mobile command post and an unmanned tracked vehicle for military purposes.

Skeleton to deliver graphene supercapacitor for UGV image

Skeleton Technologies' high power cells will be used to deliver energy efficiency and product reliability to the UGV, which can be used for a wide range of defense requirements including reconnaissance and observer missions, targeting weapon systems and providing support solutions such as medical supplies. The universal platform allows operators to optimize their vehicle fleet and reduce life cycle management costs with simplified maintenance and spare supplies.

Seamlessly bonded graphene and CNTs form a 3D material that maintains conductivity

Sep 07, 2015

In a research funded by a U.S. Department of Defense-Multidisciplinary University Research Initiative grant and Wenzhou Medical University, an international team of scientists has developed what is referred to as the first one-step process for making seamless carbon-based nanomaterials that possess superior thermal, electrical and mechanical properties in 3D. The research may hold potential for increased energy storage in high efficiency batteries and supercapacitors, increasing the efficiency of energy conversion in solar cells, for lightweight thermal coatings and more. 

The group's early testing showed that a 3D fiber-like supercapacitor made with uninterrupted fibers of carbon nanotubes and graphene matched or even surpassed bettered the reported record-high capacities for such devices. When tested as a counter electrode in a dye-sensitized solar cell, the material enabled the cell to convert power with up to 6.8% efficiency and more than doubled the performance of a similar cell that used an expensive platinum wire counter electrode. 

IDTechEx's analyst explains his views on the graphene market

Sep 04, 2015

Dr Khasha Ghaffarzadeh, IDTechExA few weeks ago we reported on a new IDTechEx market report, in which they predict that the graphene market will reach nearly $200 million by 2026, with the estimation that the largest sectors will be composites, energy applications and graphene coatings.

We were very interested in learning more, and Dr Khasha Ghaffarzadeh, IDTechEx's head of consulting was kind enough to answer a few questions and explain the company's view on the graphene market.

Q: IDTechEx has been following graphene for a long time with dedicated events and reports. Why is this new material interesting for IDTechEx?

We have a long track record of analyzing emerging advanced materials such as quantum dots, CNTs, Ag nanostructures, silicon nanostructures, OLED materials, etc. We were however pulled into the world of graphene by our clients’ questions. Once in, we soon realized that there is a big synergy between graphene and our events. in fact, our events on supercapacitors and printed electronics were the right near-term addressable market for graphene, and that is why we managed to rapidly build up the largest business-focused event on graphene. Our events on graphene are held in the USA and Europe each year – see

Rice scientists embed metals into LIG to benefit fuel cells and supercapacitors

Aug 21, 2015

Scientists from Rice University have managed to embed metallic nanoparticles into their previously-developed LIG (laser-induced graphene, a flexible film with a surface of porous graphene made by exposing a common plastic to a commercial laser-scribing beam), that turn the material into a catalyst for fuel cells and various other applications.

Rice scientists improve LIG for fuel cells image

The researchers have now found a way to enhance the product with reactive metals and turn it into "metal oxide-laser induced graphene" (MO-LIG), a new candidate to replace expensive metals like platinum in catalytic fuel-cell applications in which oxygen and hydrogen are converted to water and electricity. The scientists state that a major advantage of this process is that commercial polymers can be used, with the addition of inexpensive metal salts. They are then subjected to the laser scriber, which generates metal nanoparticles embedded in graphene. In effect, the laser generates graphene in the open air at room temperature.

UK researchers working with graphene inks to develop improved batteries and supercapacitors

Aug 05, 2015

Researchers at Manchester Metropolitan University in the UK, funded by £500,000 from the Engineering and Physical Sciences Research Council, are striving to use graphene inks to print intricate 3D structures, in hopes to increase the charge storage of batteries and supercapacitors that they create. 

The scientists are involved in a project, meant to run about three and a half years, to create graphene-based energy storage systems. They are trying to achieve a conductive ink that blends the extraordinary properties of graphene with the ease of use of 3D printing to be manipulated into a structure that’s beneficial for batteries and supercapacitors.

Skeleton Technologies enters the truck market with its graphene-based supercapacitor technology

Aug 04, 2015

Skeleton Technologies logoSkeleton Technologies, the manufacturer of graphene-based supercapacitors, has entered the commercial truck fleet market. The company recently launched a graphene-based device that helps truck drivers start their engines after long periods of inactivity or in cold weather. 

Launched under brand name SkelStart ESM, the device delivers a powerful surge of energy to a truck’s engine to make sure it will start even after long periods of inactivity or in cold weather. The firm explained that it also eliminates the need for drivers to leave their trucks idling.
