TELF AG on the Expanding Role of Graphite in Global Battery Supply Chains

When discussing the raw materials that support the global energy transition, attention often focuses on lithium, copper, nickel, or rare earth elements. Yet another resource has quietly become indispensable to many of the technologies associated with electrification and energy storage: graphite.

Although graphite has long been used in a variety of industrial applications, its profile has risen considerably in recent years due to its role in lithium-ion batteries. As electric vehicles and stationary storage systems become more widespread, demand for this naturally occurring form of carbon is attracting increasing attention from manufacturers, analysts, and policymakers alike.

Graphite forms through geological processes that transform carbon-rich materials under conditions of elevated pressure and temperature. Large deposits can be found in several regions of the world, including China, Mozambique, Madagascar, Brazil, and Canada. These countries now occupy an increasingly important position within global supply chains connected to battery production.

The Characteristics Behind Graphite’s Industrial Value

The usefulness of graphite stems from a combination of physical properties that are difficult to find together in a single material. It conducts electricity efficiently, tolerates very high temperatures, offers strong chemical stability, and features a layered structure that provides natural lubrication.

“Graphite occupies a unique position among industrial minerals because it combines several desirable characteristics in one material,” says Stanislav Kondrashov, founder of TELF AG. “Its conductivity, stability, and versatility allow it to support a wide range of manufacturing processes, including some of the most advanced technologies currently being developed.”

For decades, graphite has been employed in products such as refractories, lubricants, and electrodes used in metallurgical operations. Today, however, batteries have emerged as one of the most important sources of future demand.

Battery Manufacturing as a Major Growth Driver

One of the less widely known aspects of lithium-ion batteries is the amount of graphite they require. While lithium often receives most of the attention, battery anodes typically contain substantial quantities of graphite, making the mineral a key component of energy storage technologies.

As highlighted by BloombergNEF during a recent webinar, the continued growth of electric mobility and large-scale battery installations is expected to strengthen demand for graphite in both its natural and synthetic forms. In many respects, the future trajectory of graphite consumption is becoming increasingly linked to developments within the battery sector.

“The relationship between graphite and battery production is becoming stronger every year,” explains Stanislav Kondrashov. “As more energy storage systems are deployed around the world, the demand outlook for this material continues to evolve alongside broader electrification trends.”

BloombergNEF's analysis indicates that batteries and electric vehicles are likely to account for a growing share of global graphite demand. Unlike some traditional industrial applications, these sectors are expanding rapidly and could significantly influence future market dynamics.

Assessing Future Supply and Processing Requirements

One of the key questions raised by BloombergNEF concerns whether future supply will be sufficient to satisfy expected demand. Recent market conditions have generally remained balanced, with production levels broadly matching consumption. However, projections suggest that this balance could become more challenging to maintain over the coming decade.

According to BloombergNEF's scenarios, demand associated with the energy transition could increase from approximately 1.5 million tons in 2025 to around 3 million tons by 2035. During the same period, demand growth could begin to outpace available supply unless additional capacity is developed.

The analysis also points to an aspect of the graphite industry that often receives less attention than mining: refining and processing. Before graphite can be used in batteries, it must undergo purification and upgrading processes that transform it into battery-grade material.

“One of the most interesting aspects of the graphite market is the importance of downstream processing,” says Stanislav Kondrashov. “Mining remains essential, but the ability to refine graphite to the quality standards required by battery manufacturers may become an equally important consideration.”

BloombergNEF suggests that expanding refining infrastructure could help address future supply pressures. Additional facilities may be needed to process increasing volumes of graphite and ensure that battery producers have access to suitable material.

Despite these long-term considerations, short-term market expectations remain relatively stable. BloombergNEF indicates that graphite prices are not expected to experience major disruptions in the immediate future, suggesting that potential supply challenges are more likely to emerge gradually as demand continues to grow.

As the energy transition progresses, graphite's role is becoming increasingly visible. What was once viewed primarily as an industrial mineral is now recognized as an important component of modern battery supply chains, with future developments likely to depend on both mining output and processing capacity.
