As the need for clean, reliable energy continues to grow and expand, the market for clean energy produced with graphene batteries continues to improve. Graphene is a carbon-based material that may be the best heat and electricity conducting material ever discovered.

We can eliminate society’s carbon footprint by finding uses for carbon that are so valuable it makes no sense to waste it out of our smokestacks, turbines, or tailpipes. In this regard, graphene has the potential to offer clean energy now, in the near future, and for future generations to come. Imagine a strong, light, widely available material that can conduct electricity with greatly reduced energy loss. On small or large grids, graphene will revolutionize production and distribution of energy from power plants to cell phones.

Graphene is the perfect conductor—it offers relatively little resistance to electrons, carries electricity better than even superb conductors such as copper. Unlike superconductors that need to be cooled to low temperatures to function, graphene's remarkable conductivity works at room temperature.

By 2022, the market for graphene batteries is predicted to reach $115 million. The potential beyond that as the technology grows and improves, is one of the main more and more companies worldwide have attracted significant interest in the development of graphene-based energy.  The time for investing in graphene batteries is now.

A Graphene Breakthrough Hints at the Future of Battery Power


Palm Beach, FL, August 29, 2018

Graphene, nicknamed the “wonder material” for its unlimited amount of potential applications, is on the cusp of revolutionizing energy and energy storage. Eco-friendly and sustainable, graphene is extremely lightweight, chemically inert, and is a potent conductor of electrical and thermal energy.

That the wonder material is making a resurgence, at least in the eyes of investors, is not surprising. Years of R&D have shown enormous possibility that graphene-based battery powered technology has in store for the field of energy storage.

Graphene enhances and improves conventional battery electrode materials significantly. Batteries made of graphene are lighter, more durable, improves energy density and heightens capacity to provide far greater energy storage, and thus extend the battery's life span. Graphene also adds conductivity without the amounts of carbon found in conventional batteries.

Press Release: Signet Announces Hycarb, Inc. Acquisition

Thomas Donaldson, President, Signet International Holdings, Inc. (SIGN), announced today that SIGN has executed a Letter of Intent for the Acquisition of HyCarb, Inc., a Florida Corporation operating in association with the University of Central Florida in Orlando, FL.

HyCarb is a leader in Graphene technology development and is currently completing  the prototype of its first phase, the “HyCarb Coin Cell Battery. ”  The battery is expected to be ready for manufacturing within the next year.

“This new generation Graphene battery has proven to be amazing,” says Donaldson. “Within the next twelve months, we will be on the market delivering a coin cell battery far superior than the Lithium Ion battery in use today.”

“Our batteries have five times the life of the regular Lithium Ion Batteries,” says Ms Sigrid Cottrell, CEO of HyCarb. “We can deliver a true eco-battery that is a “greener,” safer battery whose unique attributes include being quicker to charge with a much greater electric storage capacity.  It is less toxic, up to 99% recyclable and has no thermal runaway, so it will not catch fire.”

Donaldson added that upon full subscription to its Private Placement, the company would proceed to set up its pilot plant to commercialize these coin cell batteries and create it’s next generation of batteries that will include; pouch cell, 10 Kilowatt hour and the beginning formulations for their one Megawatt hour batteries. It will also meet the criteria of many other industrial demands such as: wearable and portable electronics, home and commercial utilities, medical devices, grid renewable energy and micro grids.

HyCarb has also met with agencies of the Department Of Defense whose requirements HyCarb will meet to optimize power supply and reduce diesel fuel use. HyCarb will be able to furnish a new process of re-charging electric cars and creating a reliable ultra-lightweight battery for the aerospace industry.
