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.
NanoGraf begins production at scale to provide Military with better batteries
NanoGraf, an advanced battery material company, announced earlier this month the successful completion of the first large volume production run of its M38 18650 cell for the U.S. military.
Nanograf, formerly called SiNode Systems, pursues advances in Lithium-ion battery anodes for a wide range of industries from consumer electronics to electric vehicles. NanoGraf explaines that it uses a proprietary silicon alloy-graphene material architecture to overcome the silicon anode technical hurdles. The combination of silicon-based alloys and a flexible 3D graphene network helps stabilize the active material during charge and discharge. The company’s manufacturing process is different from others that rely on expensive and complex vapor deposition-based systems. Instead, a wet chemistry process has been developed that is highly scalable and already proven in a multi-ton-scale pilot manufacturing line in Japan. The anode material drops into existing electrode mixing and coating equipment and has been validated in large-scale battery manufacturing facilities.
Researchers announce graphene plasmon breakthrough to advance photonic-electronic technology
NTT Corporation, along with The University of Tokyo and National Institute for Materials Science (NIMS), showed that graphene plasmon wave packets can be generated, manipulated and read out on-chip using terahertz electronics.
The team managed to electrically generate and control graphene plasmon wave packets with a pulse width of 1.2 picoseconds. This result shows that the phase and amplitude of a terahertz signal can be controlled electrically by using graphene plasmons. It enables terahertz signal processing, a method different from conventional electrical circuit technology using transistors and is expected to contribute to realizing ultrahigh-speed signal processing in the future.

Inbrain Neuroelectronics gets ready for first-in-human testing of its graphene-based brain implant
Inbrain Neuroelectronics has designed a brain implant that can both read signals and stimulate brain impulses. Its brain-computer interface (BCI) uses graphene to create a high-resolution interface with the brain. Now, the Company has announced it is gearing up for its first-in-human testing, planed for this summer.
The technology is a type of brain-computer interface (BCI), which have been used for medical diagnostics, as communication devices for people who can’t speak, and to control external equipment, including robotic limbs. However, Inbrain intends to transform its BCI technology into a therapeutic tool for patients with neurological issues such as Parkinson’s disease.

This new technique involves the use of “fuzzy” graphene to improve the performance of semiconductor-based photoelectrodes, which initialize electrochemical transformations following the absorption of light. The term fuzzy refers to a form of graphene that has a rough or irregular surface with a porous and three-dimensional (3D) structure, as opposed to smooth or flat layers, with enhanced properties like surface area, reactivity or adhesion to a silicon molecule, or substrate.

Researchers use engineered graphene material to improve the performance of intraneural peripheral nerve electrodes
Limb neuroprostheses aim to restore motor and sensory functions in amputated or severely nerve-injured patients. These devices use neural interfaces to record and stimulate nerve action potentials, creating a bidirectional connection with the nervous system. Most neural interfaces are based on standard metal microelectrodes.

Researchers at the Autonomous University of Barcelona (UAB) and ICN2 have demonstrated in animal models how Engineered Graphene for Neural Interface (EGNITE), a derivative of graphene, allows the creation of smaller electrodes, which can interact more selectively with the nerves they stimulate, thus improving the efficacy of the prostheses. The study also demonstrated that EGNITE is biocompatible, showing that its implantation is safe.
