Introducing R1H: Crumpled Graphene Sheets for Next-Generation Applications

Rimere, in partnership with ACS Material, has unveiled its latest breakthrough in advanced nanomaterials: the R1H crumpled graphene sheets. Produced using a proprietary sequential hybrid plasma technology, the R1H offers a unique morphology and performance profile that sets it apart from conventional graphene materials. Importantly, this cutting-edge material is derived from a sustainable feedstock—natural gas—ensuring both scalability and environmental responsibility.

Why Crumpled Graphene?

Unlike traditional flat graphene, the R1H sheets are designed with folds and wrinkles that transform their structural and electrochemical performance. This crumpled morphology offers multiple advantages:

• Enhanced Ionic Transport:Crumples and folds behave like open-pore texture of micro-, meso-, and macropores facilitating rapid ionic movement, ideal for energy storage applications.
• Superior Conductivity: Maintains high electrical conductivity while minimizing internal resistance.
• Anti-Aggregation: Ability to prevent re-stacking into multi-layer graphene preserving high surface area for greater utilization.
• Improved Durability: Provides a flexible scaffold that withstands thermal and physical expansion.
• Improved Energy Density: The folds in the graphene lattice create electron pooling which enhance energy density.

Key Benefits for Applications

The R1H is engineered to deliver performance improvements across several industries:

• Energy Storage: Higher specific surface area (225 m²/g) and reduced ion diffusion length enhance high-rate and pulse-power capabilities, making R1H highly suitable for supercapacitors and advanced batteries.
• Electronics & Conductive Materials: With conductivity up to 4000 S/m and purity over 99% carbon, R1H enables next-generation conductive inks, coatings, and composites.
• Durable Nanostructures: Its robust crumpled form makes it a reliable building block in thermal and mechanical applications.

Comparison with Other Graphene Types

• Versus CVD Graphene: R1H offers comparable purity at significantly lower cost, with better durability.
• Versus Exfoliated Graphite: R1H delivers high conductivity and surface area. It’s morphology outperforms exfoliated graphite in demanding applications by it’s ability to prevent re-stacking into multi-layer graphene for greater utilization. 

Crumpled graphene sheets are more than a novel material—they represent a new standard in balancing cost, durability, and performance for industries that demand the very best in advanced materials.
