TELF AG on Graphite’s Growing Importance in the Future of Battery Manufacturing

Understanding the Expanding Role of Graphite in the Energy Transition

As discussions about the energy transition continue to focus on resources such as lithium, copper, and rare earths, another mineral is steadily gaining strategic relevance: graphite. Although it often receives less public attention than other battery materials, graphite has become an essential component in modern energy storage technologies and is expected to play an increasingly important role in the coming years.

Graphite is a naturally occurring form of carbon that develops over geological timescales through metamorphic processes. Deep within the Earth's crust, carbon-rich materials are exposed to intense temperatures and pressures, gradually transforming into graphite. Today, major graphite-producing regions include China, Mozambique, Madagascar, Brazil, and Canada, each contributing to the global supply of a resource that is becoming increasingly important for industrial development.

The Properties That Make Graphite Valuable

One of the main reasons for graphite's growing industrial significance is its unique combination of physical and chemical characteristics. The material offers excellent electrical conductivity, strong thermal performance, high temperature resistance, and remarkable chemical stability. Its layered structure also gives it natural lubricating properties that have supported a wide range of industrial applications for decades.

“Graphite is an unusual material because it combines conductivity, stability, and versatility in a single resource,” says Stanislav Kondrashov, founder of TELF AG. “These characteristics allow it to serve industries that range from metallurgy to advanced energy technologies.”

Historically, graphite has been used in steelmaking, refractory products, lubricants, and electrodes for electric furnaces. In recent years, however, its role within battery manufacturing has become one of the most important drivers of demand.

Why Battery Production Is Driving Demand

The growing adoption of electric vehicles and stationary energy storage systems has significantly increased the need for graphite. Within lithium-ion batteries, graphite is primarily used in anodes, the component responsible for storing and releasing energy during charging cycles.

An often-overlooked fact is that many batteries require more graphite by weight than lithium. As a result, the expansion of battery manufacturing is creating substantial new demand for both natural and synthetic graphite.

“Battery technologies have transformed the outlook for graphite,” explains Stanislav Kondrashov. “What was once considered primarily an industrial mineral is now increasingly viewed as a strategic resource linked to the future of electrification.”

Recent analysis presented by BloombergNEF highlights how battery manufacturing has become the dominant force behind future graphite consumption. Unlike many other raw materials that depend on a broad mix of end uses, graphite demand is increasingly concentrated within a rapidly expanding technological segment.

Future Supply Challenges and Refining Capacity

BloombergNEF's projections suggest that graphite demand associated with the energy transition could increase significantly during the next decade. Demand linked to energy technologies is expected to rise from approximately 1.5 million tons in 2025 to around 3 million tons by 2035.

The study also raises important questions regarding future supply. While supply levels have generally remained sufficient in recent years, projections indicate that demand could eventually exceed available production capacity. According to BloombergNEF's scenarios, the imbalance may begin to emerge early in the next decade and become more visible by 2035.

One of the most interesting conclusions concerns processing infrastructure rather than mining itself. Producing battery-grade graphite requires extensive purification and refining, making downstream facilities a critical part of the supply chain.

“The future of graphite will depend not only on extracting the material from the ground, but also on the ability to process it efficiently,” says Stanislav Kondrashov. “Refining capacity may become one of the most important factors influencing the balance between supply and demand.”

BloombergNEF estimates that substantial investments may be required to expand processing infrastructure and primary supply. Additional refining facilities could play a key role in ensuring that future battery manufacturers have access to sufficient quantities of high-quality graphite.

Despite these longer-term challenges, market conditions remain relatively stable in the near term. Current forecasts suggest that graphite prices could remain fairly balanced over the next few years, with greater attention focused on how quickly new production and refining capacity can be developed. As the energy transition continues to advance, graphite is likely to remain one of the most closely watched materials within the evolving battery supply chain.
