Superior Graphite, established in 1917 as Superior Flake Groundbreaking Company, has developed into a global manufacturer of advanced graphite and carbon materials. Based in Chicago, Illinois, the company specializes in electro-thermal treatment and purification of graphite materials, serving various industries including battery production, metallurgy, and thermal management. With manufacturing facilities in the United States and Sweden, Superior Graphite delivers consistent, high-quality products through its environmentally conscious Green Graphitization Technology – a continuous purification process that maintains efficiency while reducing environmental impact. The company’s commitment to innovation is demonstrated through its extensive research and development efforts, resulting in purpose-manufactured materials that meet specific industry requirements.
Battery Technology
Superior Graphite’s contribution to battery technology centers on its FormulaBTTM product line, specifically engineered for energy storage applications. These graphite-based materials serve as essential components in lithium-ion batteries, advanced lead-acid batteries, and fuel cells. The company’s manufacturing process ensures high purity levels and consistent particle distribution, which are crucial for optimal battery performance.
The company’s thermal purification technology produces battery-grade graphite with superior conductivity and long-term stability. This process eliminates the need for chemical purification, resulting in environmentally responsible production methods that reduce energy consumption by 70-80%. Superior Graphite’s materials enhance battery efficiency through improved charge acceptance and cycle life, particularly important for electric vehicle applications.
For advanced lead-acid batteries, Superior Graphite’s thermally purified expanded graphite improves performance under High-Rate Partial-State-of-Charge conditions. The company’s products also provide mechanical stability and electrical conductivity for alkaline batteries, contributing to enhanced overall performance and reliability.
Recent Projects
In recent developments, Superior Graphite has focused on expanding its manufacturing capabilities with a new Specialty Carbon Plant in Hopkinsville, Kentucky. The company has also undertaken the construction of an advanced anode materials facility, demonstrating its commitment to meeting growing demand in the battery sector.
Superior Graphite recently completed a strategic realignment, implementing a multi-year plan focused on investments in specialty high-temperature products and infrastructure improvements. As part of this strategy, the company divested its recarburizer business (Desulco and X-Carb) to Unimetal, allowing greater focus on core operations and future growth areas.
Investors
Superior Graphite operates as a privately owned company. While specific investor information is not publicly available, the company has appointed Accelerate Capital and Stanhope Capital to manage capital raising initiatives for its new anode materials facility. This partnership indicates ongoing efforts to secure funding for expansion projects and technological advancement.
