The growth of the expandable graphite industry is attributed to the stringent fire-safety norms, which further increase the demand for flame-retardant graphite and fire-resistant graphite materials for use in electric vehicles, driving the growth of expandable graphite use for batteries and high-temperature graphite applications. Technological innovations in graphite intercalation compounds are gaining ground for expanded graphite flakes, influencing the expandable graphite market trends and expandable graphite market size. Major expandable graphite producers, such as NOVONIX, meanwhile, grew their synthetic anode capacity, underpinning market stability.

U.S. natural graphite imports accounted for 84,000 tons in 2023, 89.3% of which was flake and high-purity graphite, resulting in key sizes of the expandable graphite market. In 2022, the Vidalia project received a 220-million-dollar federal grant, targeting a capacity of 45,000 t/yr and thus increasing its share in the expandable graphite market. The company also kept supply relatively steady through new export restrictions in China, further supporting its analysis of the expandable graphite market.

Expandable Graphite Market Dynamics:

Drivers:

• Expansion of EV battery supply chains accelerates expandable graphite for batteries adoption

Growth in global production of electric vehicles is driving demand for high-temperature holdup graphite and expandable graphite for batteries, due to the rise of lithium-ion anodes and thermal cooling systems. In 2023, U.S. imports of natural graphite, predominantly flake and high-purity grades essential for battery uses, amounted to 84,000 tons, the US Geological Survey says. This trend and also, and also because of domestic projects such as the Vidalia plant, is helping to drive growth in the expandable graphite market, to increase their share of the expandable graphite market in advanced energy storage systems.

• Tightening Chinese export controls spur supply diversification among expandable graphite companies

New export licensing in December 2023 from China for graphite intercalation compounds saw the leading companies of expandable graphite diversify their source of supply to geographic regions such as Africa and North America. This is helpful to stable supply of flame-retardant graphite and fireproof graphite material. Key companies such as SGL Carbon were the leading manufacturers to ensure continuation despite the limitations, shaping the trends of the expandable graphite market and maintaining the size of the expandable graphite market against geopolitical challenges thus boosting the steady expansion of the market.

Restraints:

• Scale-up timelines for new expandable graphite projects delay the supply response, hindering market growth

New projects, even the ones that do get federal support, frequently take a long time to permit and build out to a commercial scale. Even with major reserve expansions, such as at Graphite Creek, the output could be years off. The above-mentioned delays delay immediate growth in fire-resistant graphite material supply, influencing expandable graphite market growth, and means that the demand of the current expandable graphite market share is below a demand level that should have existed. The disparity between the planned capacity and actual production is a common short-term limiting factor for the world market.
