Active Anode Materials Manufacturing

Active Anode materials (AAM) are the materials in a battery’s anode that store and release lithium ions during charge and discharge. By manufacturing AAM from both natural graphite (derived from the Graphite Creek mine) and synthetic graphite, Graphite One intends to complete America’s graphite materials supply chain.

Graphite is available in two forms: natural graphite (“NG”) and synthetic graphite (“SG”). Both must be further processed to convert each into AAM to effectively function in lithium-ion batteries. AAM is designed and manufactured to meet each customer’s specifications. The AAM design necessary to each particular specification required selection from a range of primary component combinations of NG AAM and SG AAM, either separately or in blends, and sometimes with other materials such as silicon and SiO. The specifications can generally be categorized to attain fast charging, high energy density, or longer life cycles.

Graphite One plans to make both SG AAM and NG AAM for the electric vehicle and energy storage systems markets. The process for making each can generally be separated into three phases: preparation of the precursor materials, graphitization or purification of the precursor materials, and finishing/blending of the graphitized or purified material to produce the final AAM product. The precursor materials for SG AAM include petroleum cokes and pitches. For NG AAM, natural graphite concentrate and pitches. The following schematics generally describe the process for producing each.

Natural Graphite

  • Accounts for the majority of lithium-ion battery active anode material used in EVs and energy storage systems.
  • High energy efficiency in production
  • Strong supply chain relevance and versatility across various industries.

Synthetic Graphite

  • Engineerable to meet precise technical specifications.
  • Extremely high purity and consistency.
  • Engineered particle size, shape, and performance.
  • Superior durability and life cycle in demanding applications.

Graphite FAQs

Graphite serves as the preferred anode material (negative electrode) in almost all lithium-ion batteries, allowing lithium ions to flow in and out (Intercalation and deintercalation) during charging and discharging. Without anode materials like graphite, batteries can’t function. In short, graphite is a foundational material for clean energy tech while still being indispensable to traditional industries like steelmaking.

Graphite delivers scale, cost efficiency, and sustainability in applications where performance alone isn’t enough—especially in batteries and heavy industry.

Graphite is essential to battery supply chains, where both artificial and natural graphite makes up a large share of lithium-ion battery anode material. The world cannot scale technological innovation without it, because it offers high energy effiiency at lower cost than artificial alternatives.

  • Energy storage – Anode materials for Li-ion batteries for electric vehicles and electrical grid storage applications.
  • Renewable energy technologies – Solar panels, wind turbine rotors.
  • Data and computing centers – Backup power batteries, thermal management and cooling, infrastructure materials.
  • Industrial components – Steelmaking electrodes, lubricants, refractories.
  • Aerospace and military – Carbon fibers, heat shields, and radiators.
  • Graphene – Early-stage but with high upside in electronics and advanced material engineering.
  • Consumer electronics

Over 70% of graphite today comes from China, creating a critical need for diversified supply. Many federal governments across the world including the United States, Canada, European Union, Japan, and Australia classify graphite as critical because it’s essential to national economies and security, but vulnerable to supply chain risks.

Graphite is valued for its unique combination of electrical and thermal conductivity, strength, and heat resistance.

  • Largest share of a battery – In a lithium-ion battery, graphite makes up 25-30% of the total mass and is the single largest raw material input by volume.
  • Irreplaceable role in the anode – Graphite is the only proven anode material at commercial scale. Despite research into silicon, lithium metal, and other alternatives, none have yet matched graphite’s combination of, cost, and manufacturability. This makes it a structural bottleneck in the EV supply chain.
  • No substitution risk in the near term – While cathode chemistries (where lithium, nickel, cobalt, and manganese are used) are evolving rapidly, the anode side remains dominated (>95%) by graphite. It sits at the intersection of electrochemistry, cost, manufacturability, and scale—and no alternative checks all four boxes today.
