GRAPHENE

Key to electrification

The unique selling point of our patented product, Toroidal graphene, is the capacity to boost the electrical conductivity of copper to quantifiable improvements of 300-375%, a level that exceeds industry demands and significantly outperforms our main competitor, 2D graphene, and translates into tangible benefits such as increased energy efficiency and reduced carbon emissions, which aligns with sustainability goals and supports the green transition.

ELECTRIFICATION

In the quest for a sustainable and low-carbon future, electrification emerges as a crucial catalyst. Its fundamental role lies in facilitating the widespread use of renewable energy and reducing our reliance on fossil fuels. At the core of electrification's importance is the extensive adoption of electric vehicles (EVs), which serve as a key driver. EVs are not just components, but rather integral elements that contribute significantly to the electrification process. By embracing EVs, we propel the agenda of electrification, leading to a reduction in carbon emissions, the integration of renewable energy sources, improved air quality, enhanced energy efficiency, technological innovation, and ultimately, a transition towards a more environmentally friendly future.

Problem

    1. Limited Driving Range: One of the primary barriers to the widespread adoption of EVs is the limited driving range offered by current battery technology. Many consumers are concerned about running out of charge before reaching their destination, leading to range anxiety and hesitation to switch from internal combustion engine vehicles (ICEVs) to EVs.
    2. Slow Charging Speeds: Another challenge is the relatively slow charging speeds of EVs compared to refueling times for ICEVs. Long charging times can inconvenience drivers, especially during long trips or when charging infrastructure is limited, further exacerbating range anxiety and hindering the adoption of EVs.

Solution

Utilizing conductivity-enhanced copper in the various components of the EV battery system and the charging infrastructure can significantly benefit driving range and faster charging times:

    1. Busbars & interconnects: Conductivity-enhanced copper busbars and interconnects reduce electrical resistance, enabling more efficient flow of electricity between battery cells. This minimizes energy loss during charging and discharging, maximizing the amount of energy available for driving and extending the vehicle’s range. Additionally, the transfer of electricity from busbars to battery cells becomes more efficient, ensuring even distribution of the electrical load across the battery pack. Enhanced conductivity also facilitates faster charging rates, allowing for quicker replenishment of energy during charging sessions.
    2. Terminals & wiring: Enhanced conductivity in copper terminals and wiring ensures efficient transmission of electricity, reducing energy loss and voltage drops along the wiring. This maximizes the amount of electricity delivered to the battery cells, leading to faster charging times and extended driving range per charge. Faster and more reliable transfer of electricity between the battery pack and the vehicle’s electrical system also results in shorter charging times and quicker acceleration, enhancing the driving range and overall performance of the electric vehicle.
    3. Cooling plates: Enhanced conductivity in copper cooling plates improves their ability to dissipate heat generated during charging and discharging cycles. Efficient heat dissipation helps maintain optimal operating temperatures within the battery pack, preserving battery life and ensuring consistent performance. This allows for faster charging without compromising safety or longevity.

In the charging infrastructure, conductivity-enhanced copper reduces electrical resistance in cables and connectors, minimizing energy loss during the charging process. This means that more of the electricity delivered from the charging station reaches the vehicle’s battery, maximizing the amount of energy available for driving and extending the vehicle’s range per charge. Additionally, lower resistance enables faster transfer of electricity from the charging station to the vehicle’s battery, resulting in shorter charging times and enhanced practicality of EVs. Conductivity-enhanced copper components in the charging infrastructure also contribute to optimized distribution of electricity, compatibility with high-power charging, and enhanced thermal management, further improving charging times, driving range, and overall usability of electric vehicles.

By addressing key barriers such as limited driving range and slow charging speeds, the introduction of Toroidal graphene can accelerate the widespread adoption of EVs. Increased driving range, faster charging times, and improved affordability make EVs more appealing to consumers, driving market growth and promoting a transition to sustainable transportation. As the sole provider of Toroidal graphene, we offer unparalleled advantages and opportunities for investors and stakeholders seeking to capitalize on the rapid growth of the EV market and beyond.

INDUSTRIAL
CASE STUDIES

The performance enhancement capability of Toroidal graphene has been documented by us in several industrial case studies, where components made of composite materials nano-structured by Toroidal graphene at concentrations of 0.0025-0.01wt% was demonstrated under real operational conditions (TRL-level 7):

• The collaboration between Solerial Matusions, Scania, and the Swedish Metals Research Institute (Swerim) in 2022 in a pre-study to develop a lead-free bronze alloy for truck gearbox pads resulted in the creation of a lead-free Toroidal graphene-Bronze alloy with significantly higher wear resistance than traditional leaded bronze.

TECHNOLOGY

Toroidal graphene molecule

The toroidal graphene molecule is a nano-scientifically engineered zero-dimensional1 sp2-hybridized carbon allotrope, consisting of 20-40 defect-free graphene layers without function-group content, geometrically fixed in a closed conjugated system with delocalized pi-electrons interacting freely in circular motion in the closed loop of the cyclic structure of the toroid instead of being occupied in pi-bonds with adjacent graphene layers. Thus, the toroidal graphene molecule exhibits delocalization of pi-electrons from the multiple layers in coherent oscillations across the entire molecule.

1. 0D nanomaterials have zero dimensions larger than the nanoscale and thus have all three dimensions confined at the nanoscale, as opposed to 2D nanomaterials like 2D graphene, which have two dimensions larger than the nanoscale, and one dimension confined at the nanoscale. Nanoscale refers to dimensions on the order of nanometers, ranging from 1 to 100 nanometers.

Giant resonance

The coherent motion of delocalized pi-electrons arises from quantum mechanical principles, where neighboring pi-electrons exhibit wave-like constructive interference patterns, which occur when the wavefunctions of pi-electrons of the multiple layers align in phase, leading to an amplification of the oscillations that ultimately trigger a resonant response.

This resonance phenomenon, known as giant resonance, leads to a significant enhancement of the electromagnetic field of the molecule, amplifying its intensity by a factor of 30,000, as observed in Raman scattering experiments, where the amplification results in stronger Raman signals, providing direct evidence of the giant resonance phenomenon.

NANO-
STRUCTURING
CAPABILIITY

Extreme electron mobility together with exceptional structural and thermal integrity makes Toroidal graphene the ideal nanostructuring agent for enhancing composite materials such as metal alloys, engineering plastics, and carbon fiber.

The incorporation of toroidal graphene molecules into a composite material significantly influences its overall performance. When uniformly dispersed, they establish a stable internal network within the material. The network stability comes from the alignment and attraction of temporary dipoles between the toroidal graphene molecules, a phenomenon known as van der Waals forces.

The van der Waals forces exerted by the toroidal graphene molecules demonstrate heightened strength and expanded range, owing to modified electron density and electronic polarization induced by giant resonance.

Van der Waals-forces interaction range in copper

The interlayer shear properties of the toroidal graphene molecule are characterized by exceptionally high shear strength, preventing the individual graphene layers from being separated, even during extreme processing conditions. This phenomenon arises from the strong covalent bonding within each defect-free graphene layer and the quantum mechanical interlayer interactions, which collectively resist shear deformation and ensure structural integrity.

Densified interfacial layers

Dispersing toroidal graphene molecules uniformly in a copper matrix with a spacing of 550 nm, and thereby ensuring optimal interaction between the temporary dipoles of adjacent toroidal graphene molecules, promotes the formation of denser, more compact interfacial layers between the toroidal graphene molecules and the surrounding copper atoms.
Amplified van der Waals forces between the toroidal graphene molecules and the copper atoms play a crucial role in promoting stronger interactions at the interfaces. The attractive forces pull the copper atoms closer to the toroidal graphene molecules, thereby contributing to the densification of the interfacial layers with improved cohesion and adhesion.

Superior electrical and thermal conductivity

The densified interfacial layers within the nanostructured copper facilitate better contact between the toroidal graphene molecules and the copper atoms, improving transfer pathways and mobility of charge carriers and phonons through the composite material, as well as reducing scattering, and minimizing energy losses, ultimately reducing resistance and thus contributing to higher electrical and thermal conductivity.
Stronger intermolecular interactions also lead to a smoother surface and reduced frictional resistance, resulting in improved durability and longevity of the material.

In the case of carbon fiber composites, an interfacial layer is formed around the carbon fibers as well.

COMPETITION

Competing technologies in the nanomaterial industry are mainly based on Carbon nanotubes (CNTs) or 2D graphene.

Carbon nanotubes

CNTs have been used as an additive in tens of thousands of attempts to modify materials and exits from this market include Bayer AG which described the potential applications of CNTs as ‘fragmented with comprehensive commercialization not likely in the foreseeable future’.

Torus vs Tube: Semi-scientific demonstration by the co-founder of the lifebuoy-shape of the toroidal graphene molecule that provides a micro-mechanical flotation device-style interlocking adding to the degree of efficiency as a nano-structuring agent as opposed to the detrimental sliding of the atomically smooth walls of the CNTs, which eventually will cause stress concentration and crack initiation.

2D graphene

In the competitive landscape of nanomaterials, 2D graphene stands out as a key player, having been recognized by the Nobel Prize in Physics in 2010 for its remarkable properties. However, while the nanostructure of the graphene layer holds great promise, realizing its potential in real-world applications requires exploring alternative graphene solutions that offer defect-free graphene layers with greater structural and thermal integrity, such as the toroidal graphene molecule.

AEROSPACE
ULTRA
LIGHT-
WEIGHTING

With a systems-level approach, which involves considering the potential for ultra lightweighting from the beginning of the design process, it is possible to optimize the design of a 300-seat, 140-ton carbon fiber jet with a list price of $325m.

One kilogram of our product ultra-lightweights the carbon fiber parts of a 140-ton carbon fiber jet and addresses the following five primary areas of aerospace lightweighting:

Weight savings – Our product allows for weight savings of 40% of the carbon fiber composite parts or a total of 28 tons, which equals cost savings of $8.7m.

Fuel consumption – Our product allows for a reduction in fuel consumption by 20% or 10+ tons of fuel for a single Atlantic crossing, which equals cost savings of $10m over the life of the aircraft.

CO2 emissions – Our product allows for a reduction in CO2 emissions by 20% or 30+ tons for a single Atlantic crossing.

Range – Our product improves range flexibility by 20% or 2,800 km, thereby increasing the number of possible non-stop destinations around the world.

Aircraft lightning protection – Carbon fiber composites cannot mitigate the potentially damaging electromagnetic effects from a lightning strike. The most frequently selected solution to this problem is to introduce metals back into the aircraft. The metal mesh and expanded foil added to the composite structure layup for this purpose are negating any lightweighting measures and don’t contribute to structural strength. Carbon fiber composites enhanced with our product serves as an electrical shield around the structure that protects against lightning strikes and at the same time contributes to structural strength.
