Battery-Grade Graphene for Energy Density and Charge Rate

Graphene is projected to be a $5B+ market by 2030, and energy storage is one of the arenas where advanced carbon materials are under serious evaluation. Yet teams sourcing graphene for battery development today confront a frustrating landscape. Supply chain fragmentation, inconsistent product quality, and the inability to customize formulations for specific applications have left manufacturers settling for inferior materials or expensive alternatives.

For a battery program, those problems are not cosmetic. Cell development is an exercise in repeatability: a formulation is only as useful as the confidence that the next shipment of material will behave like the last one. When the carbon input drifts from batch to batch, or when a supplier cannot adapt the material to the chemistry it is meant to serve, the qualification work built on top of it is put at risk.

Rimere approaches the problem from a different starting point. Rather than sourcing graphene through a fragmented supply chain, Rimere builds it — using plasma to turn natural gas into graphene and clean hydrogen, on a single platform designed to keep its outputs consistent.

Rimere's energy-storage material claim is straightforward: battery-grade graphene for dramatically increased energy density and charge rates, suitable for EV, grid storage, and next-generation cell chemistries. That single sentence covers three distinct classes of buyer, each with a different reason to care about the carbon going into their cells.

• Electric vehicles. Energy density and charge rate sit at the center of EV cell design — they shape how far a vehicle travels and how long it spends at a charger. Battery-grade graphene targets both.
• Grid storage. Stationary storage operates on a different duty cycle than a vehicle, but it draws on the same underlying need: cells that store more energy and accept charge quickly, built from materials a manufacturer can source with confidence.
• Next-generation cell chemistries. Teams developing chemistries beyond today's mainstream designs need a carbon supplier that can adapt the material to the chemistry — not force the chemistry to accommodate whatever material happens to be available.

Across all three, the common thread is that the material has to be dependable before it can be transformative. That is where Rimere's production platform matters as much as the graphene itself.

Rimere's process begins with the fuel already moving through the world's infrastructure. Natural gas flows from the existing pipeline network into Rimere's sequential plasma reactor — and the platform runs on it whatever its makeup. Methane, ethane, heavier hydrocarbons, varying impurities and gas qualities: Rimere processes the full range of real-world natural gas, not one idealized feedstock, and no new distribution network is required.

Inside the reactor, high-energy plasma fields break the hydrocarbon bonds in the gas directly. Because the molecules are pulled apart rather than burned, no oxygen is consumed and no CO2 is formed. Rimere's sequential plasma process — protected by the company's core IP portfolio — controls this dissociation precisely enough to tune the carbon it produces.

The result is the property battery manufacturers have been missing. Whatever the input gas composition, the outputs stay consistent: solid carbon, built into graphene and custom nano-carbon structures to specification, and clean hydrogen, released as a zero-carbon fuel. Variable gas in; the same high-value products out; zero CO2. For a cell developer, that means the graphene arriving at the line is not subject to the variability of the feedstock behind it — the process absorbs the variation so the material does not have to.

All Rimere carbon is currently being proven out in two unique categories — crumpled nano-sheets and branched spheres — with new products in development. R1H, the crumpled-sheet graphene, has been imaged by TEM at the 200-nanometer scale and by SEM at 5 microns, showing actual production material rather than a laboratory one-off. R1L, the branched nano-spheres, is a carbon nano-sphere material imaged by SEM. Every material comes off the same system with no mechanical changes: plasma is programmable chemistry.

Verification does not rest on Rimere's word alone. The materials are third-party verified by Intertek and ACS Materials, and tunable to specification — and Rimere is scaling toward commercial availability with ACS Material as its global distribution partner. The material has also demonstrated measurable performance in an adjacent field: in radio-frequency shielding, Rimere carbon has been proven to shield more than 95% of EMI.

For battery teams whose chemistry demands a particular carbon rather than a commodity powder, that tunability is the point. Learn how Rimere works with manufacturers as a custom graphene supplier, adapting formulations to the application instead of the other way around.

Energy storage exists to decarbonize energy — so the materials inside it invite scrutiny of their own footprint. Rimere's process answers that scrutiny at the level of chemistry. Because plasma dissociation pulls hydrocarbon molecules apart at their bonds rather than combusting them, no oxygen is consumed and no CO2 is formed. The outputs are high-quality carbon materials and clean hydrogen — all with zero carbon footprint. For buyers accounting for emissions across their supply chain, the graphene itself arrives without a CO2 bill attached to its production.

The delivery story scales the same way. The global natural gas pipeline represents a trillion-dollar distribution infrastructure reaching every major industrial center on earth, and Rimere converts it into the world's first nano-material delivery network. Strategic investors, including Clean Energy Fuels (NASDAQ: CLNE), back that vision of converting the natural gas pipeline into the nano-material pipeline.
