Invention Reference Number
This technology introduces an innovative pellet holder system that enhances the electrochemical graphitization process for carbon-based materials. Designed to improve electrical connectivity, electrolyte accessibility, and process scalability, the system addresses key challenges in producing high-quality graphite for energy storage and advanced materials applications. The design supports consistent results across industrial settings, contributing to improved material performance and production efficiency.
Description
The pellet holder system enables improved handling and processing of carbonaceous particles during electrochemical graphitization—a method used to convert amorphous carbon into structured graphite. Unlike conventional fixtures that can limit uniform contact or electrolyte distribution, this system employs specially configured assemblies designed for balanced electrical conduction and efficient electrolyte exposure. The modular design accommodates a variety of electrode and electrolyte materials, including chloride-based electrolytes, and supports corrosion resistance for repeated industrial use. The technology’s flexible configuration promotes reproducibility and quality control at multiple scales, making it suitable for large-volume production environments. While specific design and fabrication parameters remain proprietary, the approach offers enhanced process uniformity, durability, and efficiency compared to current state-of-the-art methods.
