Why Graphene?

Graphene is a single layer of graphite; an array of carbon atoms arranged in a hexagonal honeycomb lattice. Graphene is expected to enable energy storage devices with several new features that do not exist in the current technology. Nanotech Energy is working on converting this dream into a reality.

It’s 6x lighter than steel

1m m/s

It carries electrons at 1 million meters per second​

How we make graphene

Nanotech Energy follows what is known to be a top-down method in producing our graphene.


Graphene production starts with chemically oxidizing graphite particles: introducing oxygen (functional groups) in between the graphite layers.


The layers are then exfoliated into water-soluble graphite (graphene) oxide single sheets.


The single-layered Graphene oxide sheets are then reduced back to graphene using proprietary chemical and hydrothermal methods.

Printed circuits

Given its excellent mechanical and electronic properties, graphene is expected to play a critical role in the progress of printed electronics.

Thin, flexible, low-cost and environmentally friendly – this is just a snapshot of what printed electronics can offer.

The rise of this technology can be ascribed to its potential in providing cost-effective solutions to large-area electronic devices at a fraction of the cost of traditional semiconductor technology.

Promising applications

Nanotech Energy’s research and the market for printed electronics is rapidly growing with promising applications in smart packaging, organic solar cells, wearable electronics, and electronic papers.

Flexible electronics

Nanotech Energy has developed a simple, yet effective, method for the direct laser writing of graphene circuits that are flexible, conductive and suitable for the next generation of flexible electronics. Devices of any shapes and structures can be printed within minutes.

$13.6 B

The overall printed electronics market is estimated to reach USD 13.6 billion by 2023 from USD 6.8 billion in 2018.

Graphene supercapacitors

Supercapacitors are attractive energy storage devices with the ability to recharge in seconds rather than hours like traditional lithium-ion batteries.

Supercapacitors are also maintenance free and can be used for up to a million charge/discharge cycles. Their high power density and excellent low temperature performance have made them the technology of choice for back-up power, cold starting, flash cameras, and regenerative braking. They also play an important role in the progress of hybrid and electric vehicles.

However, the low energy density of current supercapacitors is the main impediment to realizing the full commercial potential of this technology.

This has triggered tremendous research efforts on Nanotech Energy’s part in order to develop new electrode materials that are capable of providing a huge amount of energy in a short period of time.

As a result, our graphene has potential to transform the industry of printed electronics, energy storage, composite materials, solar cells, desalination membranes and other areas.

What is Reduced Graphene Oxide?

Since the graphene industry is growing very rapidly, it is important to distinguish between different graphene products currently available in the market.

The first pieces of single and few-layer graphene nanosheets were obtained through the exfoliation of bulk graphite using scotch tape. Although this route leads to non-defective pristine graphene, its low yield makes it unpractical for large scale. Mass production of graphene was made possible through chemical exfoliation of graphite. This can be achieved by direct exfoliation of graphite in a liquid, with or without a surfactant or by inserting chemical species between graphite interlayers to weaken the forces holding them together, thus facilitating their exfoliation. While these techniques are widely used for the production of graphene with low defects, the product is usually thick and is often referred to as nanoplatelets. These nanoplatelets are suitable for applications requiring high electrical and thermal conductivity but their low surface area and poor dispersibility in various solvents make their further processing difficult.

Solution-based approaches involve chemical oxidation of graphite to graphite oxide, which can be exfoliated to individual layers of graphene oxide sheets by mild ultrasonication or shear mixing in water. Graphene oxide is electrically insulating but can be converted back to the conductive form by reduction using chemical, thermal, solvothermal or laser techniques. The resulting reduced graphene oxide (often abbreviated as rGO) can be processed from solution, opening up vast opportunities for the use of graphene in many technological applications. The processability of rGO allows its direct incorporation into composites where it can improve mechanical and electrical properties of the host material. More importantly, rGO can achieve high surface areas in excess of 1000 m2/g, much higher than other techniques for exfoliating graphite.

It was discovered that the remaining edge defects on the surface of rGO can be beneficial for rapid electron transfer and higher catalytic activities, making this form of graphene ideal for electrochemical and energy storage applications in batteries and supercapacitors. It also shows promise as an active ingredient in inks and coatings for the growing markets of printed electronics and smart packaging. rGO becomes an obvious solution where the users are looking for large quantities of graphene for industrial applications.
