Is graphene ready for use in a gigawatt-hour battery manufacturing?

VoltaXplore, a joint venture of NanoXplore and Martinrea has announced plans to build a gigafactory in Canada that uses graphene enhanced anodes. NanoXplore’s proprietary graphene-silicon anodes are currently used in VoltaXplore’s 18650 cylindrical cells that are manufactured in a recently commissioned demonstration battery plant in Montreal. These batteries have successfully demonstrated high specific capacity with excellent cycle life and are on track to be mass-produced in Canada. From raw materials to cylindrical cells, this talk will give you an overview of how graphene’s promise for massive energy storage is finally coming true.

The unique feature of Sixonia Tech's E-Graphenes is the combination of properties that were previously incompatible for graphenes on large scale: easy processability (without additives) + high quality (conductivity). This is enabled by the technology of electrochemical exfoliation in combination with in situ functionalization. Additionally, such functionalization allows for property profiles and processing properties to be adaptable to the respective target application (e.g. dispersibility without surfactants in a solvent of choice and high electrical conductivity at the same time).
The promising potential of these graphenes has been shown - among others - in conductive coatings towards light-weight heating and sensing textiles and as conductive additives in battery electrodes, which can significantly increase high-power capacity and improved cycling stability.

DexMat manufactures high-performance Galvorn carbon nanotube (CNT) fibers and films using a proprietary solution processing technology. We aim to supplant heavy, rigid metals used for wiring in the aerospace, wearable electronics, and medical device markets. Metal wiring is heavy and is prone to fatigue failure in electronics. Lightweight, flexible wires and cables made with DexMat materials are up to 90 % lighter, 10 times stronger, and have over 100 times higher flex life than metal wiring. Conductive CNT fiber/thread can be sewn directly into fabric or clothing, is machine washable, and is capable of picking up electrical signals from the body such as a pulse simply by being in contact with skin. Furthermore, Galvorn threads can be readily assembled into fabrics and used as dry contact electrodes for EKG measurement. DexMat is seeking to build strong relationships with leading apparel and consumer electronics companies to accelerate the development of DexMat products into wearable electronics and e-textile applications. High-tech apparel for performance athletes, medical EKG monitoring clothing, military uniforms with portable antennas for wireless communications, and wearable fabric batteries are just a few potential entry applications for DexMat CNT products.

Atrago is a display technology innovator that has developed a novel graphene MEMS solution. We are targeting the more advanced display sub-segments such as augmented reality (AR), virtual reality (VR) glasses and heads-up displays (HUD) as the first part of a broader mainstream adoption strategy for our new technology

AR/ VR devices and HUDs require exceptional displays to enhance user experience. Currently, display manufacturers seek to achieve high resolution, high refresh rates and low power consumption. Standard technologies lack the performance and efficiency required and rely on an internal light generation causing high consumption of power. Atrago's technology combines the best performance in each category guaranteeing a premium and sustainable solution.

Atrago has developed a graphene-based electro-opto-mechanical system addressing the needs of the AR/VR and head-up displays industry. The solution is a reflective display whose pixels are mechanical micro-optical cavities made of graphene nano-sheets. The pixels can be electrically controlled to modulate ambient light and produce natural colours. This eliminates the need to use battery power to generate light in bright environments.

Applied Nanolayers BV (ANL) has spent the last years developing solutions for graphene production and integration, such as wafer scale growth processes and tools and wafer-to- wafer transfer processes and tools, combined with wafer scale quality analysis, and wafer scale device fabrication. We now offer a foundry service to integrate these materials on existing semiconductor technology to precisely those customers who wish to bring their graphene application to a higher TRL. This allows SME’s as well as larger companies to develop their intended 2D material device applications without having to invest upfront in expensive production infrastructure.
ANL has its own 200 mm automated CVD platform to enable the consistent growth of high- quality graphene. For the transfer ANL has developed a unique wafer-to-wafer transfer technique with dry graphene transfer. This transfer method is more reliable and easier to automate than liquid based transfer methods. It also provides better control over stress, strain and wrinkles in the graphene layer, which results in more uniform final device performance.
Next to its foundry service ANL has also developed a graphene Application Development Kit (ADK). This enables ANL’s customers to execute fast prototyping using ANL’s graphene and use a manual dry bond. This method provides the best possible results, only to be topped by ANL’s automated transfer. The ADK can be used at wafer level, but it can also be cut in pieces and transferred to individual chips or other small size applications.

Graphene and other 2D materials cover metal-semiconductor-insulator, and can be engineered to meet industrial needs. On the other hand, a number of startups have faced significant challenges to get qualified for commercialization and often failed. Why?! Is a replacement model of existing materials/films/composites not working? Choice of existing market versus emerging market? This talk will discuss potential solutions to overcome these challenges on the basis of my experiences as a former founder of nanomaterials startups and investor. The latest trend in sustainability and its effect on 2D materials venture will be touched as well.

Graphene is well known for improving performance properties that include corrosion resistance, barrier properties, and mechanical durability. The challenge for formulators has always been the ease of incorporation of graphene, which is extremely challenging. Graphene’s high surface area requires difficult incorporation processes and the handling of a dusty light material that could present workplace hazards.
One well-known solution to this challenge is to work with graphene dispersions, where the dry material has been uniformly wetted, stabilized and incorporated into a liquid matrix. These dispersed graphene powders can work quite well, but the limitations include relatively low graphene content, constraints imposed by the other ingredients used in the dispersion, and, most importantly, storage issues that include shelf stability and settling.
This presentation will introduce graphene composite powders that eliminate many of these problems and allow easy incorporation of graphene into many types of coating systems, including solvent based, water based and powder coatings.

Field-effect transistor (FET)-based biosensing devices have demonstrated advantages over other sensing methods including, high sensitivity, simplicity and rapid detection of small amounts of analytes. Further, since FETs offer an extremely small and compact form factor while eliminating the chemical steps involved in a diagnostic assay, they have shown a great deal of promise for use as the basis for Point of Need (PON) diagnostic devices. Such PON systems could fill an important gap where conventional molecular diagnostics are not readily available such as in the home. Graphene-based FETs in particular offer ultrasensitive, rapid, and accurate detection of DNA, proteins, bacteria, and viruses. Graphene can be easily functionalized to create selective surface reactions to a wide range of biological targets that can then be detected electronically. Highly specific capture/receptor molecules can be attached to the graphene surface to identify harmful pathogens with extremely high sensitively and specificity. The electrical signal that is generated on the graphene surface as a result of the pathogen target molecule binding to the capture/receptor molecule can be easily measured without any additional chemical steps or readers. The incredibly wide range of molecular targets that can be detected by graphene has created a great deal of interest in developing these sensors for use in compact PON disease diagnostic systems.
GRIP Molecular Technologies has been working in collaboration with the Department of Physics at Boston College to develop an electronic biosensor based on GFET’s for ultrasensitive multiplexed detection of respiratory viral antigens for an in-home diagnostic platform. Using aptamers as capture probes, and a GFET prototype developed at Boston College, protein detection using synthetic SARS-CoV-2 spike, Influenza HA and RSV proteins has been demonstrated at an LoD that is 50-100x more sensitive than POC based ELISA assays. In addition, these antigens have been detected at the same time on a single device with multiplexing. Using electrophoresis, detection of antibiotic resistant bacteria using peptide capture probes has also been accomplished. We will outline the device optimization enabling this breakthrough as well as next steps towards PON devices.

The biggest challenge for carbon nanotubes and graphene commercialization is the production of industrial quantities with reasonable cost and high-volume supply.
Raymor Industries is a Canadian high-tech company using thermal plasma process to produce carbon nanostructures at large scale. Through their subsidiaries, NanoIntegris and Graphene LP, Raymor also specializes in the production of enriched, single-walled carbon nanotubes and graphene dispersions. It has taken iterations between industrial R&D, collaboration with academic researchers and industrial partners for Raymor to offer an affordable and optimized process with proven success in the integration of both carbon structures in different applications including electronics, energy and more.
In this talk, we will present the main products of Raymor-NanoIntegris, the high scale production of carbon nanotubes and graphene by using plasma and some examples of their current applications for battery and electronic technologies.

NanoGraf Corporation recently validated that its novel silicon-based materials technology can enable a quantum leap in 18650 cell performance by achieving an energy density of over 800 Wh/L, while also retaining best-in-class cycle life, low-temperature operation, and rate performance. NanoGraf’s composite silicon-graphene G6 anode material is differentiated both through performance (>90% FCE, 1300 mAh/g) and drop-in readiness, which has been demonstrated with dozens of cell manufacturing partners worldwide. In addition, G6 represents a breakthrough in manufacturing and cost since it can be produced in two steps and replaces expensive, complex vapor deposition-based systems with a low-cost, aqueous coating process.
In this talk, we will discuss NanoGraf’s proprietary material architecture consisting of silicon-based alloys and a flexible 3D graphene network that helps stabilize the active material during charge and discharge. This technology solves long-standing technical hurdles surrounding silicon anodes and enables >30% energy density improvements in commercial cylindrical cells. The material is produced at multi-ton scales now, with additional scale-up in the United States to be completed in 2022. Finally, we will discuss how NanoGraf-enabled 18650 cells are being utilized in applications for the US military, where both superior performance and weight reduction are critical to enabling high-functioning members of the armed forces

GDI has developed a next generation 100% silicon anode, patented protected technology that is directly bonded to copper foil and other advanced substrates for high power and high energy. This anode technology is capable of over 2000mAh/cc in active material, and loadings as high as 5mAh/cm2. Commercial cathodes have been limited to around 4mAh/cm2 of areal energy, and at those loadings have poor power and fast charging capabilities. As a result most of the market needs to choose between high power, fast charging cell chemistries with low energy ratings, or high energy cells that cannot charge fast and have lower power. This presented GDI with the need to develop a cathode that can provide both high areal energy, and deliver high C-rates to our anode. Thus GDI has started working with a key partner on formulating a new type of cathode to match in full cells with GDI's anode.The result is a cathode with high areal loadings that can still provide the silicon anode with high power when needed, and achieve hundreds of fast charging cycles without having to switch from an energy cell format to a power cell format. As a result GDI has developed a cell architecture that can function as both an energy cell or power cell for different applications and depths of discharges, without thinning the electrodes and losing energy density.

Energy storage applications have seen increasingly rigorous demand for improved performance. Particularly driven by the increased effort on commercialization of electric vehicles, there is a significant drive to maximize energy density of batteries, while also minimizing the battery cost. In order to meet these technical requirements, the Lithium-ion Battery (LIB) industry has recently devoted a significant effort develop alternative cathode chemistries, including, but not limited to permutations of Nickel Manganese Cobalt and Nickel enhanced spinel materials (e.g., NMC811, LNO, LMNO).

A variety of key technical issues arise for these novel materials, ranging from low conductivity to increased interfacial degradations and structural instability which accelerate under high voltage and elevated temperatures, potentially leading to material instability and thermal runaway.

These challenges present an opportunity for Volexion’s pristine graphene protective encapsulation technology, which concurrently addresses shortfalls in conductivity, interfacial instability and degradation, thereby facilitating direct industrial integration of novel high-performance cathode materials in industrial applications.
