Allied Graphite: Company Profile and Technical Capabilities
Executive Overview
Allied Graphite is an American advanced materials technology company focused on manufacturing battery-grade graphite materials for lithium-ion batteries and clean energy applications. Headquartered in Mesa, Arizona, the company was originally founded in 2014 as Urbix Resources (later Urbix Inc.) before rebranding to Allied Graphite.
The company is addressing a critical bottleneck in the North American battery supply chain: domestic processing and supply of coated, spheroidized, and purified graphite (CSPG). Anodes in electric vehicle (EV) batteries and stationary energy storage systems rely almost entirely on refined graphite. Allied Graphite bridges the gap between raw natural graphite mining and gigafactory cell manufacturing by refining raw flake concentrate into high-purity, battery-ready active anode material.

Core Operations and Manufacturing Platform
Allied Graphite operates a development and pilot-scale facility in Mesa, Arizona, where it translates bench-scale mineral processing and chemical engineering into repeatable industrial workflows. Rather than employing traditional, energy-intensive, or hydrofluoric-acid-dependent methods, the company has developed proprietary purification and particle-shaping unit operations designed for environmental safety, yield efficiency, and lower carbon intensity.
The company's core operations span four integrated technical stages:
1. Feedstock Sourcing and Characterization
Allied Graphite maintains strategic upstream alignment with Graphcoa, a natural graphite producer in Brazil backed by Appian Capital. This relationship ensures a dedicated, long-term supply of high-grade natural flake graphite concentrate across the Americas. Incoming feedstock undergoes detailed characterization to map specific impurity profiles before processing begins.
2. Impurity-Informed Purification
Conventional natural graphite purification often relies on aggressive, one-size-fits-all acid leaching or high-temperature thermal purification. Allied Graphite uses a disciplined, impurity-specific chemical purification process. By targeting specific mineral contaminants rather than applying generic severe treatments, the platform achieves battery-grade purity levels (typically 99.95%+ carbon content) while preserving flake structural integrity, lowering chemical inputs, and optimizing recovery yields.
3. Controlled Milling, Spheroidization, and Classification
Active battery anodes require spherical particles to achieve optimal packing density and electrolyte flow within the cell. Allied Graphite operates custom mechanical milling and shaping circuits that transform planar graphite flakes into spherical morphologies. High-precision air classification platforms separate and tailor particle size distributions (such as D10, D50, and D90 metrics) to customer specifications, minimizing ultrafine waste.
4. Surface Coating and Thermal Treatment
To prevent premature battery degradation, spherical graphite must undergo surface modification. Allied Graphite applies specialized carbon coatings to the exterior of the spheroidized particles. This coating establishes a uniform solid electrolyte interphase (SEI) layer, prevents electrolyte co-intercalation, boosts first-cycle coulombic efficiency, and extends battery cycle life.
Products and Material Solutions
Allied Graphite does not offer generic, off-the-shelf catalog commodities. Instead, it utilizes a configurable manufacturing platform that produces customized, battery-grade materials tailored to specific OEM and cell chemistry requirements.
Coated Spherical Purified Graphite (CSPG)
The company’s primary commercial deliverable is battery-ready CSPG, the essential active anode material used in commercial lithium-ion batteries. Key characteristics include:
* High tap density for dense electrode packing.
* Customized particle size distributions (typically centered around 10 to 20 micrometers depending on cell design).
* Low surface area (BET) after carbon coating to minimize irreversible capacity loss during initial charging.
* High reversible capacity and extended calendar and cycle durability under fast-charging conditions.
Uncoated Spherical Purified Graphite (SPG)
Intermediate spherical purified graphite intended for cell manufacturers and researchers who apply in-house proprietary coatings or blend natural graphite with synthetic graphite and silicon anodes.
Tailored Particle Fractions and Industrial Carbon Products
Byproducts and specific particle distributions generated during classification and shaping are processed for non-battery specialty markets, including thermal management composites, conductive additives, and specialized industrial formulations.
Engineering and Commercialization Services
In addition to physical materials, Allied Graphite provides engineering and collaborative development services to support battery manufacturers from initial cell design through commercial scale-up:
- Qualification Testing and Data Packages: Supplying prospective EV manufacturers and tier-one battery makers with testing batches, electrochemical test results, full impurity assays, and technical data sheets required for rigorous automotive qualification.
- Custom Specification Engineering: Adjusting milling, shaping, and coating parameters to achieve target customer requirements for tap density, specific surface area, particle morphology, and cycle life.
- Supply Chain Integration: Providing North American gigafactories with an alternative, transparent, and geopolitically secure supply route compliant with domestic sourcing requirements under the U.S. Inflation Reduction Act (IRA).
Scaling and Commercial Roadmap
Allied Graphite is advancing toward commercial production through disciplined transition and detailed engineering programs in partnership with global engineering firms such as Hatch:
- Pilot Validation (Mesa, Arizona): Demonstration of process repeatability, impurity control, and customer-grade material generation.
- Commercial Phase One: Construction of an initial commercial-scale manufacturing plant targeting approximately 14,000 tonnes per annum (tpa) of CSPG production.
- Phase Two Expansion: Planned multi-fold scale-up designed to meet accelerating demand from North American gigafactories and defense-related supply initiatives.
