  • Graphene vs. Graphite: What’s the Difference?

    Oct 01, 2025 | ACS MATERIAL LLC

    Multiple allotropes from diamond to fullerenes manifest the exquisiteness of carbon, which is a diverse element in nature. Additionally, two forms of carbon, which are famous among the industries, are graphene and graphite. Many people confuse them, but they are entirely different forms. 

    One has fueled the industries for centuries, while the other is redefining the future of technology at the atomic scale. Graphite has been considered the unrecognized element in industries for years. It features qualities like flexibility, conductivity, and independence. Therefore, experts use it in steelmaking, refractories, and lithium-ion batteries. 

    Similarly, graphene is famous as a “supermaterial”,  in modern manufacturing industries and lab research. It has excellent durability, flexibility, and electrical and thermal conductivity. So, let’s jump into the discussion for clear differentiation of graphene vs. graphite.  

     

    Structure Difference: One Layer vs. Many Layers

    Graphene is a single layer of carbon atoms that are assembled in a hexagonal pattern. The hexagonal organization of atoms gives them extraordinary strength, as it’s considered 200 times stronger than steel and yet flexible. These qualities make them a wonder material across the industries, including biomedical devices, energy storage, and aerospace.

    • It has ~ 1 nm thickness and is not visible to the eye.

    • Offer extremely high species surface ~2600 m2/g. 

    • The tensile strength = 130 GPa.

    • Elastic Modulus  =1.1 TPa 

    • It has chemically reactive edges and a surface.

    • Thermal conductivity = 5x10 103 W/mK

    • Electronical Conductivity = 106 S/m

    • Resisitance capability = = 31 Ω/sq 

    • Charge mobility = (2 x 105 cm2/V.s)

    On the other hand, graphite is composed of a stack of multiple graphene layers stacked on top of each other. However, these layers are weakly bound, which is why it’s soft and slippery.  The softness makes it perfect to use for manufacturing pencils, batteries, and industrial lubricants. 

    • It has 3D dimensionality, unlike graphene. 

    • A graphite atom has a thickness of > 5 nm.

    • Graphite can be visible. 

    • Graphite has an opaque and gray-black appearance. 

    • It has a tensile strength = 4.8 GPa. 

    • Have relatively good conductivity, but not as good as graphene. 

    • Thermal conductivity =24 W/mK

    • Resistivity = 0.006 Ω/cm

    • Relatively resistant to chemical reactions. 

    Thus, the distinction between one layer and multiple layers depends on why graphene exhibits more unique mechanical and electrical properties that cannot be achieved. Always select a Reliable Graphene Supplier to buy chemicals and top-notch materials.

    Strength & Flexibility: Tiny but Mighty

    Graphene has incredible strength; a sheet just one atom thick can support heavy loads without breaking. Therefore, scientists consider them tougher materials than metals as well.

     

    The 2-dimensional arrangement makes it the thinnest material and retains its durability and conductivity. Although it’s 200 times stronger, it remains ultralightweight and flexible, which makes it ideal for aerospace materials, composites, and advanced structures. 

    Graphite is much weaker than graphene; however, its experts have increased its durability at high temperatures. It lacks flexibility because the stacked layers can slide apart easily due to weak van der Waals forces.

     The softness of graphite makes it worthy to use in pencils and lubricants. For manufacturers seeking flexibility and adaptability, graphite and graphene product suppliers are imperative to make formulations that ensure durability and flexibility. 

    High Electrical Conductivity 

    Research proves that graphene is famous for providing exceptional thermal and electrical conductivity in industries. Despite this, the electrons move through with minimal resistance, making them highly desirable for applications in energy storage and the electric sector. Besides, it has the highest electronic mobility ever measured. Thus, experts use CVD graphene (chemical vapor deposition graphene) in sensors, solar cells, and advanced transistors. 

    Graphite remains a good conductor, but its efficiency is reduced due to electron scattering that occurs between multiple layers. For these reasons, CVD graphene becomes preferable in flexible circuits and sensors. Whether you are dealing with smartphones or supercapacitors, selecting the Best CVD Graphene Supplier to obtain high-quality materials can maximize performance.

    Surface Area & Chemical Edge

    Between the comparison of graphene vs. graphite, surface area is another essential element. Graphene offers a theoretical surface area of ~2,600 m²/g, which ensures its high effective performance in sensing, energy storage, and adsorption. 

    Graphite oxide is a denser material because of its tightly packed layers, which means it has less area for reactions. Conversely, graphene is thin and open, which gives it a huge surface area even for the smallest amount of chemicals. This quality makes graphene far better than graphite and shines in energy devices, supercapacitors, and batteries. 

    Unique Chemistry & Reactivity

    Graphene with every atom exposed to the environment demonstrates higher surface reactivity. 

    This unique chemical reactivity of graphene makes it demanding for advanced applications. Its hexagonal and flexible structure allows property tuning for biotechnology. 

    Variations like Carboxyl Graphene or Graphene on PET substrates are designed by experts to fulfill the specific industrial requirements. And, this becomes possible due to the graphene’s highly reactive surface. 

    • Graphene on PET substrates makes transparent conductive films that are high-performing for solar panels or flexible displays. 

    • Carboxyl graphene ensures the delivery of functional groups that increase its bonding with polymers and make it useful in coatings and composites. 

    • Graphene on Copper Foil is another form that researchers and scientists use to grow high-quality graphene sheets through the chemical vapor deposition method.

    On the other hand, graphite is a chemically stable material but less versatile. Despite this, graphite restricted the reactivity because most of its atoms are buried within the stacks. 

    Thus, graphene’s ability to be modified with different chemical groups means that industry often needs to rely on Specialized Graphene Oxide Suppliers to help create custom solutions.

    Synthesis Cost and Scalability  

    Graphene has incredible potential; however, producing it at a large scale is costly for the industries. In this regard, advancements in methods like exfoliation and CVD are helping to overcome synthesis issues without compromising quality. 

    Alternatively, graphite is a naturally abundant and inexpensive material. Therefore, experts consider them an outstanding possibility for bulk applications such as steelmaking and battery anodes. Furthermore, industries are channeling investment into refining production methods for Graphene Series products to meet the commercial demand.
