New method doubles performance of 3D printed supercapacitors

Jun 19, 2016

Researchers from Lawrence Livermore National Laboratory (LLNL) and UC Santa Cruz (UCSC) have designed a technique that could double the performance of 3D printed graphene-based supercapacitors. The new technique involves sandwiching lithium ion and perchlorate ion between layers of graphene in aerogel electrodes—a process which greatly improves the capacity of the electrodes while maintaining the high rate capability of the devices.

Scientists double performance of 3D printed graphene aerogel supercapacitors

The 3D printing process used by the researchers to build the supercapacitors is a form of direct ink writing, consisting of two ion-intercalation steps before the hydrolysis of perchlorate ion intercalation compounds. According to the team “this two-step electrochemical process increases the surface area of graphene-based materials for charge storage, as well as the number of pseudo-capacitive sites that contribute additional storage capacity”.

Lomiko's Graphene ESD announces completion of supercapacitors project

Jun 01, 2016

Graphene ESD has announced the successful completion of its development project, undertaken jointly with the Research Foundation of Stony Brook University (SBU), that explored a novel method for assembly of high-voltage supercapacitor units.

The team assembled and tested a 10 V supercapacitor energy storage unit, thus proving feasibility of the high-voltage design. This development opens the door for new low-cost energy storage products. Currently, GESD is working on scale-up of the technology and an in-field evaluation of the energy storage unit.

Chinese graphene market tripled in 2015

May 02, 2016

Innova Research recently published a survey that states that the Chinese graphene market revenue for 2015 was estimated at $6.1 million, a 335.7% jump from $1.4 million for 2014.

The survey also specifies that significant progress has been made on the adoption of graphene in a number of industrial applications in 2015, namely touch screens, anti-corrosive coating, and lithium-ion batteries (LIBs). These adoptions are the primary reasons for the soaring Chinese graphene market revenue in 2015.

Versarien signs agreement for graphene-enhanced batteries and supercapacitors collaboration

Apr 20, 2016

Versarien logo imageVersarien has announced that it has entered into a Memorandum of Understanding with WMG (“Warwick Manufacturing Group”) to collaborate on the production of power storage devices such as batteries and supercapacitors using Versarien’s graphene nano platelets. Working with the SME team and battery specialists, Versarien will have access to WMG’s expertise and world leading facilities in the Energy Innovation Centre.

WMG aims to improve the competitiveness of organizations through the application of value adding innovation, new technologies and skills deployment, bringing academic rigor to industrial and organizational practice. WMG bridges the gap between academia and industry, enabling the development of innovative products.

Skeleton Technologies secures €3.5 million agreement for its graphene-based supercapacitor technology to be used in road freights

Apr 14, 2016

Skeleton Technologies logoSkeleton Technologies has signed a €3.5 million distribution agreement with French transport tech developer Adgero, that ensures modules from Skeleton Technologies be part of the world’s first Kinetic Energy Recovery Systems (KERS) for road freight. Under the agreement, Adgero will source SkelMod 160V modules exclusively for the Adgero hybrid system pioneered to increase efficiency for the truck transport industry.

The Adgero KERS system is scheduled to be road tested next month by leading UK transport company, Eddie Stobart, ahead of Adgero’s expected series production this year. The truck company will test the KERS system in a curtainsider trailer – built by one of the largest manufacturers in Europe, SDC Trailers – and unveiled at the Commercial Vehicle Show in Birmingham later this month.

XG Sciences plans $24 million IPO

Apr 04, 2016

XG Sciences logoXG Sciences aims to raise $24 million through an initial public offering to fund operations, as it continues to commercialize composite materials for lithium-ion batteries and other applications. Of the $24 million XGS hopes to raise through an IPO, $11.4 million will go to fund operations for the next two years, “by which time the company might begin generating positive cash flow from operations.” Proceeds from the IPO would also go to working capital, and to increase capacity and its sales and technical service staff.

While the company has accumulated operating losses exceeding $43 million during its development stage, the securities filing cites a growing customer list and order volume. XG Sciences projects 2016 revenues of $5 million to $10 million through the sale of graphene and graphene nanoplatelets for electronic and industrial products that use lithium-ion batteries. A number of companies are currently testing XG Sciences’ materials for applications including lithium-ion batteries, supercapacitors, thermal shielding, inks and coatings, printed electronics, construction products, composites and military uses.

Malaysia plans to release 360 new graphene-based products by 2020

Mar 14, 2016

NanoMalaysia, a company under the Malaysian Ministry of Science, Technology and Innovation (MOSTI) set up to promote nanotechnology commercialization activities, has announced that 360 new products will be commercialized according to the government plans, with Malaysia's National Graphene Action Plan (NGAP) 2020 assisting with some of these products. NGAP2020 aims to generate about 9,000 jobs and RM20 billion ($4.86 Billion) GNI impact by the year 2020.

The minister of Science, Technology and Innovation (MOSTI) announced during a recent ceremony that companies have signed memorandums of agreement (MoUs), which will help to build a local graphene ecosystem and speed up downstream adoption. This adoption of graphene will involve downstream graphene-based application development for specialty and consumer products ranging from tyres, automotive components, water pipes and ultra-capacitors.

It was a fascinating segment that shed light on the company's graphene-related activities, some of which (as can be seen in the image above) are energy storage applications, sensors, various electronic devices, photonics, optoelectronics and even graphene manufacturing - which shows that the company is really aiming at completing a full circle of graphene use.

Graphene impressions from the Mobile World Summit

Feb 29, 2016

Last week Barcelona hosted the Mobile World Congress trade show, and it was a very large and impressive conference - with over 100,000 visitors and thousands of exhibiting companies. This year the MWC included a graphene pavilion, organized by the ICFO and the Graphene Flagship, Europe's $1 billion research project initiative.

The Graphene Pavilion was very impressive, with several companies showcasing real graphene products and prototype devices, and also several research groups from leading Universities. The Pavilion consisted of 11 companies and 9 research centers - and you could see graphene materials, graphene supercapacitors (From Zap&Go, soon to hit the market), large graphene EMI shielding films (from GNext), graphene sensors and graphene-based RFID tags and antennas. In the photo below you can see an air quality prototype sensor made from graphene developed by Libre SRL (PiAndBi).
