Grafoid Inc. and the University of Waterloo Announce a JV Agreement to Develop High Performance Graphene Electrochemical Energy Systems



OTTAWA, ONTARIO--(Marketwired - April 16, 2013) - Focus Graphite Inc. (TSX VENTURE:FMS)(OTCQX:FCSMF)(FRANKFURT:FKC) on behalf of Grafoid Inc. ("Grafoid") is pleased to announce the signing of a two-year R&D agreement between Grafoid Inc. and the University of Waterloo to investigate and develop a graphene-based composite for electrochemical energy storage for the automotive and/or portable electronics sectors.

Gary Economo, President and CEO of Focus Graphite Inc. and Grafoid Inc., said the objective of the agreement is to research and develop patentable applications using Grafoid's unique investment which derives graphene from raw, graphite ore to target specialty high value graphene derivatives ranging from sulfur graphene to nanoporous graphene foam.

Some of the new graphene materials will contribute positively as a powerful next generation composite for fuel cell/electrochemical supercapacitor applications, he said.

Those applications include but are not limited to: electrodes, nanocatalyst support, electrolyte membranes and bipolar plates, transparent electrodes and other potential applications which create high-efficiency solutions in electrochemical energy systems and portable electronics.

"Today's announcement marks Grafoid's fifth publicly declared graphene development project with a major academic or corporate institution, and the third related directly to a next generation green technology or renewable energy development project," Mr. Economo said.

This follows R&D partnering projects announced with Rutgers University's AMIPP, CVD Equipment Corporation, with Hydro-Quebec's research institute, IREQ, and with British Columbia-based CapTherm Systems, an advanced thermal management technologies developer and producer. Mr. Economo said Grafoid's investment in highly conductive graphene, combined with the University's advanced catalyst technologies could advance the science "by opening the door to a realistic, cost-competitive option to other energy solutions." 

"Given our growth agenda for 2013, we expect to be in a position to announce a number of additional application development projects throughout the course of 2013," Mr. Economo added.

Dr. Aiping Yu, Assistant Professor, Department of Chemical Engineering at the University of Waterloo will be the lead investigator of the project. Dr. Gordon Chiu, Research Scientist, Department of Chemical Engineering at the University of Waterloo will be working on the project.

Dr. Chiu said that research and discovery on graphene sulfur and nanoporous graphene is well documented and is a cornerstone for a wide range of applications"The technology for tailoring graphene for energy storage systems must be developed. This will lead to unique intellectual property assets.

"Our group's approach for targeting graphene derivatives that powerfully impact next generation energy storage systems adds significant value to commercial applications while providing invaluable knowledge and insight about the engineering of graphene and certain graphene metamaterials," Dr. Chiu said.

Dr. Yu said that graphene without proper porosity and polarity remain "a constant roadblock for entry into next generation energy storage applications.

"My group will focus on solving the specific tailoring and design of graphene to enable entry into these energy storage areas" she said. "

"Grafoid's decision to invest in reducing or removing such a roadblock is a brilliant approach of enhancing graphene for impacting fuel cells, electrochemical supercapacitors and/or other portable energy storage systems," Dr. Yu added.

Background
Alternative Energy & Graphene:
The quest for alternative energy sources is one of the most important and exciting challenges facing science and technology in the 21st century. Environmentally-friendly, efficient and sustainable energy generation and usage have become large efforts for advancing human societal needs. Graphene is a pure form of carbon with powerful characteristics which can bring about success in portable, stationary and transportation applications in high energy demanding areas in which electrochemical energy storage and conversion devices such as batteries, fuel cells and electrochemical supercapacitors are the necessary devices.

Electrochemical Supercapacitors:
Supercapacitors, a zero-emission energy storage system, have a number of high-impact characteristics, such as fast charging, long charge-discharge cycles and broad operating temperature ranges, currently used or heavily researched in hybrid or electrical vehicles, electronics, aircrafts, and smart grids for energy storage. The US Department of Energy has assigned the same importance to supercapacitors and batteries. There is much research looking at combining electrochemical supercapacitors with battery systems or fuel cells.

Fuel Cells:
A fuel cell is a zero-emission source of power, and the only byproduct of a fuel cell is water. Some fuel cells use natural gas or hydrocarbons as fuel, but even those produce far less emissions than conventional sources. As a result, fuel cells eliminate or at least vastly reduce the pollution and greenhouse gas emissions caused by burning fossil fuels, and since they are also quiet in operation, they also reduce noise pollution. Fuel cells are more efficient than combustion engines as they generate electricity electrochemically. Since they can produce electricity onsite, the waste heat produced can also be used for heating purposes. Small fuel cells are already replacing batteries in portable products.

Toyota is planning to launch fuel cell cars in 2015, and has licensed its fuel cell vehicle technology to Germany's BMW AG. BMW will use the technology to build a prototype vehicle by 2015, with plans for a market release around 2020.

By 2020, market penetration could rise as high as 1.2 million fuel cell vehicles, which would represent 7.6% of the total U.S. automotive market. Other fuel cell end users are fork lift and mining industries which continuously add profits to this growing industry.

Proton or polymer exchange membranes (PEM) have become the dominant fuel cell technology in the automotive market.The U.S. Department of Energy has set fuel cell performance standards for 2015. As of today, no technologies under development have been able to meet the DOE's targets for performance and cost.

Graphene micro super capacitors will change the world according to UCLA Prof

University of California - Los Angeles

UCLA researchers develop new technique to scale up production of graphene micro-supercapacitors

While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors.

Now, Richard Kaner, a member of the California NanoSystems Institute at UCLA and a professor of chemistry and biochemistry, and Maher El-Kady, a graduate student in Kaner's laboratory, may have changed the game.

The UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom–thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.

The new cost-effective fabrication method, described in a study published this week in the journal Nature Communications, holds promise for the mass production of these supercapacitors, which have the potential to transform electronics and other fields.

"The integration of energy-storage units with electronic circuits is challenging and often limits the miniaturization of the entire system," said Kaner, who is also a professor of materials science and engineering at UCLA's Henry Samueli School of Engineering and Applied Science. "This is because the necessary energy-storage components scale down poorly in size and are not well suited to the planar geometries of most integrated fabrication processes."

"Traditional methods for the fabrication of micro-supercapacitors involve labor-intensive lithographic techniques that have proven difficult for building cost-effective devices, thus limiting their commercial application," El-Kady said. "Instead, we used a consumer-grade LightScribe DVD burner to produce graphene micro-supercapacitors over large areas at a fraction of the cost of traditional devices. Using this technique, we have been able to produce more than 100 micro-supercapacitors on a single disc in less than 30 minutes, using inexpensive materials."

The process of miniaturization often relies on flattening technology, making devices thinner and more like a geometric plane that has only two dimensions. In developing their new micro-supercapacitor, Kaner and El-Kady used a two-dimensional sheet of carbon, known as graphene, which only has the thickness of a single atom in the third dimension.

Kaner and El-Kady took advantage of a new structural design during the fabrication. For any supercapacitor to be effective, two separated electrodes have to be positioned so that the available surface area between them is maximized. This allows the supercapacitor to store a greater charge. A previous design stacked the layers of graphene serving as electrodes, like the slices of bread on a sandwich. While this design was functional, however, it was not compatible with integrated circuits.

In their new design, the researchers placed the electrodes side by side using an interdigitated pattern, akin to interwoven fingers. This helped to maximize the accessible surface area available for each of the two electrodes while also reducing the path over which ions in the electrolyte would need to diffuse. As a result, the new supercapacitors have more charge capacity and rate capability than their stacked counterparts.
 Interestingly, the researchers found that by placing more electrodes per unit area, they boosted the micro-supercapacitor's ability to store even more charge.

Kaner and El-Kady were able to fabricate these intricate supercapacitors using an affordable and scalable technique that they had developed earlier. They glued a layer of plastic onto the surface of a DVD and then coated the plastic with a layer of graphite oxide. Then, they simply inserted the coated disc into a commercially available LightScribe optical drive — traditionally used to label DVDs — and took advantage of the drive's own laser to create the interdigitated pattern. The laser scribing is so precise that none of the "interwoven fingers" touch each other, which would short-circuit the supercapacitor.

"To label discs using LightScribe, the surface of the disc is coated with a reactive dye that changes color on exposure to the laser light. Instead of printing on this specialized coating, our approach is to coat the disc with a film of graphite oxide, which then can be directly printed on," Kaner said. "We previously found an unusual photo-thermal effect in which graphite oxide absorbs the laser light and is converted into graphene in a similar fashion to the commercial LightScribe process. With the precision of the laser, the drive renders the computer-designed pattern onto the graphite oxide film to produce the desired graphene circuits."

"The process is straightforward, cost-effective and can be done at home," El-Kady said. "One only needs a DVD burner and graphite oxide dispersion in water, which is commercially available at a moderate cost."
The new micro-supercapacitors are also highly bendable and twistable, making them potentially useful as energy-storage devices in flexible electronics like roll-up displays and TVs, e-paper, and even wearable electronics.

The researchers showed the utility of their new laser-scribed graphene micro-supercapacitor in an all-solid form, which would enable any new device incorporating them to be more easily shaped and flexible. The micro-supercapacitors can also be fabricated directly on a chip using the same technique, making them highly useful for integration into micro-electromechanical systems (MEMS) or complementary metal-oxide-semiconductors (CMOS).

These micro-supercapacitors show excellent cycling stability, an important advantage over micro-batteries, which have shorter lifespans and which could pose a major problem when embedded in permanent structures — such as biomedical implants, active radio-frequency identification tags and embedded micro-sensors — for which no maintenance or replacement is possible.

As they can be directly integrated on-chip, these micro-supercapacitors may help to better extract energy from solar, mechanical and thermal sources and thus make more efficient self-powered systems. They could also be fabricated on the backside of solar cells in both portable devices and rooftop installations to store power generated during the day for use after sundown, helping to provide electricity around the clock when connection to the grid is not possible.

"We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors," Kaner said
