Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb-like pattern. Graphene is considered to be the world's thinnest, strongest and most conductive material - of both electricity and heat. All of these properties are exciting researchers and businesses around the world - as graphene has the potential to revolutionize entire industries - in the fields of electricity, conductivity, energy generation, batteries, sensors and more.
Mechanical strength
Graphene is the world's strongest material, and can be used to enhance the strength of other materials. Dozens of researchers have demonstrated that adding even a trace amount of graphene to plastics, metals or other materials can make these materials much stronger - or lighter (as you can use a smaller amount of material to achieve the same strength).
Such graphene-enhanced composite materials can find uses in aerospace, building materials, mobile devices, and many other applications.
Thermal applications
Graphene is the most heat conductive found to date. As graphene is also strong and light, it means that it is a great material for making heat-spreading solutions, such as heat sinks or heat dissipation films. This could be useful in both microelectronics (for example to make LED lighting more efficient and longer lasting) and also in larger applications - for example thermal foils for mobile devices. Huawei's latest smartphones, for example, have adopted graphene-based thermal films.
Energy storage
Since graphene is the world's thinnest material, it also extremely high surface-area to volume ratio. This makes graphene a very promising material for use in batteries and supercapacitors. Graphene may enable batteries and supercapacitors (and even fuel-cells) that can store more energy - and charge faster, too.
The advantages of graphene batteries
Coatings ,sensors, electronics and more
Graphene has a lot of promise for additional applications: anti-corrosion coatings and paints, efficient and precise sensors, faster and efficient electronics, flexible displays, efficient solar panels, faster DNA sequencing, drug delivery, and more.
Graphene is such a great and basic building block that it seems that any industry can benefit from this new material. Time will tell where graphene will indeed make an impact - or whether other new materials will be more suitable.

Researchers design semitransparent image sensors for eye-tracking applications using graphene and QDs
A team of researchers from The Barcelona Institute of Science and Technology (ICFO) and Barcelona-based startup Qurv Technologies have designed flexible, nearly transparent graphene-enhanced image sensors that could be hidden in plain sight.
The sensors, based on graphene and quantum dots, could be integrated directly onto eyeglasses or curved windshields, placed right in front of a user’s eyes. This could make eye-tracking hardware less bulky, improve the accuracy of gaze detection, and reduce computational complexity, says Frank Koppens, who co-led the research and co-founded Qurv in 2020.
Rice team produce hydrogen and graphene from waste plastic at zero net cost
Rice University researchers have found a way to harvest hydrogen and graphene from plastic waste using a low-emissions method that could more than pay for itself.
“In this work, we converted waste plastics ⎯ including mixed waste plastics that don’t have to be sorted by type or washed ⎯ into high-yield hydrogen gas and high-value graphene,” said Kevin Wyss, a Rice doctoral alumnus and lead author of the recent study. “If the produced graphene is sold at only 5% of current market value ⎯ a 95% off sale! ⎯ clean hydrogen could be produced for free.”

Researchers develop aminoferrocene-based graphene system to bring about room temperature quantum computing
Researchers at the University of Texas at El Paso (UTEP) have developed a highly magnetic quantum computing material — 100 times more magnetic than pure iron — that functions at room temperature. The team introduced an aminoferrocene-based graphene system with room temperature superparamagnetic behavior in the long-range magnetic order.
Quantum computing has the potential to revolutionize the world, allowing massive health and science computation problems to be solved exponentially faster than by classic computing. However, before this could happen, it is vital to overcome the current drawback of only operating in subzero temperatures. “In order to make quantum computers work, we cannot use them at room temperature,” said Ahmed El-Gendy, Ph.D., an associate professor of physics at The University of Texas at El Paso. “That means we will need to cool the computers and cool all the materials, which is very expensive.”

Nanotech Energy to partner with BASF to enable production of lithium-ion batteries in North America with locally recycled content and low CO₂ footprint
BASF, a global battery materials producer, and Nanotech Energy, a developer of graphene-based energy storage products, have agreed to partner to significantly reduce the CO2 footprint of Nanotech’s lithium-ion batteries for the North American market. The agreement aims to close the loop for lithium-ion batteries in North America, with BASF producing cathode active materials from recycled metals in Battle Creek, Michigan, for the usage in lithium-ion battery cells produced by Nanotech Energy. Feeding recycled metals into the production of new lithium-ion batteries can reportedly reduce the CO2 impact of batteries by about 25% compared to the use of primary metals from mines.
Both companies will additionally partner with American Battery Technology Company (ABTC), a lithium-ion battery recycling company in Reno, Nevada, and TODA Advanced Materials Inc. (TODA) with decades of experience in manufacturing specialized pCAM (precursor for Cathode Active Material) and metal hydroxide material located in Ontario, Canada, to establish such a localized battery value chain for the North American consumer electronics and automotive industries. Along that chain, battery scrap and off-spec material from Nanotech’s pilot operation in Chico, California, as well as from its planned commercial facility will be recycled by ABTC. The battery-grade metals as recovered by ABTC – such as nickel, cobalt, manganese, and lithium – will be subsequently used by TODA and BASF to produce new precursors and cathode active materials, respectively. Nanotech will then use these materials again in its battery cell production – overall, a truly circular economy in North America.
