Graphene Powers Vehicles into the Future

The automotive industry turns to XG Sciences for graphene-enhanced solutions. Today’s vehicles contain numerous applications of graphene in production within parts and materials. This includes graphene-enhanced coatings and paints, polyurethane foams, lithium-ion batteries and elastomers and rubbers.

Graphene-Enhanced Automotive Rubber: Vehicle Tires and Components

When added to rubber tire formulas, XG Sciences xGnP® graphene nanoplatelets provide added durability and mechanical and thermal management improvements, taking tire performance to new levels. Graphene’s unique properties make it ideal for extending longevity of vehicle tires and reducing total vehicle costs.

Additional rubber applications that can be enhanced with xGnP graphene nanoplatelets include hoses, seals, grommets and belts to improve mechanical and thermal ageing performance.

Graphene for Automotive Electrification and eMobility

Graphene-silicone anodes are used in lithium-ion batteries for electric vehicles (EVs) to increase energy density, power density and improve battery longevity.

Conductive inks enhanced with graphene can also be used to conduct energy in printed circuits using very thin materials. Inks and pastes also have demonstrated thermal conductivity properties to improve heat management.

Graphene in Automotive Composites

XG Sciences xGnP can also be used in automotive thermoplastic and thermoset materials to combat challenges such as microcracking, warpage, wear, chemical attack and processing speed pressures. Composites with xGnP graphene nanoplatelets in the form of master batch or polymeric resins demonstrate improved mechanical strength, barrier resistance, thermal management and noise, vibration, and harshness (NVH) benefits.

Typical composite applications include thermal system components, casing materials, foams or other plastic components.

Other Automotive Industry Applications Enhanced by Graphene

Graphene-enhanced materials are used throughout vehicles to bring added strength, flexibility, conductivity, thermal management and numerous other benefits critical to vehicle performance, utility and longevity.

Graphene-enhanced coatings and paints are used to protect components from environmental harshness, abrasion and UVA rays. They also have antioxidant properties.

Due to their intrinsic stability, flexible and rigid graphene-enhanced properties, polyurethane foams are used throughout the vehicle, including in the passenger cabin and in the harsh under-the-hood environment – especially to reduce NVH without adding weight.

Automotive Recyclability and Sustainability

Total vehicle lifetime assessments and recyclability are a priority for design engineers in the automotive industry looking to create a sustainable future for the next generation. Recyclability and sustainability are a massive challenge requiring new design solutions that will meet CO2 emission standards of tomorrow.

By working with the XG Sciences team to design solutions using xGnP graphene nanoplatelets, you can improve mechanical properties of recycled materials to give another life to automotive components. Also, the inherent benefits of wear resistance, UV protection and barrier resistance make xGnP ideal for reducing CO2 emissions by enabling longer applications’ lifecycles, reducing their total carbon footprint impact from cradle to grave.

The Challenge

A leading automotive OEM sought out XG Sciences graphene technology to enhance various under-the-hood vehicle components, to improve the performance, strength and mechanical properties in its top-selling sports car.

The XG Sciences Solution

XG Sciences developed custom graphene nanoplatelets in polyurethane-based components, including fuel rail covers, pump covers and front engine covers. The graphene components helped to reduce weight, achieving better heat conductivity and decreased noise. XG Sciences also determined how to reduce material costs using only a very small amount of graphene. Tests conducted by the automotive OEM found that when graphene is mixed with foam constituents, there is a 17% reduction in noise, a 20% improvement in mechanical properties and a 30% improvement in heat endurance properties over a foam that was constructed without graphene.
