Collaboration Yields New High-Performance Graphene Dispersions
March 5, 2025
Somerset, NJ – NEI Corporation is pleased to announce the launch of a new line of advanced graphene dispersions developed in collaboration with HydroGraph Clean Power Inc. These innovative dispersions can be seamlessly integrated into existing electrode slurries, replacing or supplementing traditional conducting carbons. When mixed with active materials and binder, these conductive additives enable the creation of flexible electrodes, expanding design possibilities for high-performance cells.
Why is this unique?
The new FGA-1 dispersions utilize HydroGraph’s pristine Fractal GrapheneTM, produced through a proprietary detonation synthesis process. This unique graphene exhibits 100% sp2 bonding and a turbostratic arrangement with an average of six graphene layers per particle. This nanoscale structure contributes to exceptional conductivity and facilitates improved rate capability and energy density, providing a significant advantage for diverse battery applications.
“One key advantage of these conductive additives is their lower percolation threshold. Due to its 2D geometry, graphene facilitates improved interconnectivity between active material particles and the conductive network within the electrode compared to spherical carbon black particles,” said Dr. Ranjith Divigalpitiya, CSO of Hydrograph.
New Product Line: Carbon-Based Conductive Additives
The new line of advanced conductive additives, available in both NMP-based and water-based dispersions, expands NEI Corporation’s comprehensive portfolio of high-performance battery materials. This strategic addition complements NEI’s existing offerings of cathode, anode, and electrolyte materials for both lithium-ion and sodium-ion batteries, enabling the company to provide customers with even more complete and integrated solutions.
“Our collaboration with Hydrograph and the launch of these graphene dispersions demonstrates NEI’s commitment to innovation and supporting battery researchers,” said Dr. Ganesh Skandan, CEO of NEI Corporation.
