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.

3DBattery Company and NEI Corporation Receive BIRD Energy Program Grant

September 15, 2020

3DBattery Company and NEI Corporation receive grant from the BIRD Energy Program to take a Systems Approach to Next Generation of High Energy Density Lithium-ion Batteries

NEI Corporation (New Jersey, USA) and 3DBattery Company (headquartered in Israel), announced today that the BIRD Energy program has awarded the companies a $900,000 grant for the integration of an advanced anode material with a water-based electrode deposition process, leading to a new generation of high performance and low-cost Lithium-ion batteries. The eighteen-month project aims to first develop cathode materials that can be used with a water-based ion-conducting polymer binder, followed by pairing with a silicon-based anode. The performance of the new materials and associated processes will be demonstrated at the pouch-cell level.

The grant was awarded by BIRD Energy, a program established by the U.S. Department of Energy and Israel’s Ministry of Energy together with the Israel Innovation Authority. The program is managed by the Israel-U.S. BIRD (Binational Industrial Research and Development) Foundation.

BIRD Energy has a rigorous review process and selects the most technologically meritorious projects along with those that are most likely to commercialize and bring about significant impact. Selected projects address energy challenges and opportunities that are of interest to both countries.

NEI Corporation is a leader in the development, manufacture and supply of specialty lithium-ion battery materials. NEI offers a variety of cathode, anode, and electrolyte materials, with a particular forte in producing specialty materials with compositions and particle morphologies that are not commonplace. In addition, NEI has expertise in producing composite particles that have a surface coating. All NEI products are sold under the tradename NANOMYTE®.

3DBattery Company is a startup company specializing in the design, development, and manufacture of innovative energy storage solutions. The company is bringing a paradigm change in the architecture of a lithium-ion cell. 3DB’s main product is a silicon-based anode (AnoSep®), which presents an economical and scalable solution to increase battery capacity, battery cyclability, and fast charging of at least 6C (10 minutes charge to full capacity). The company has vast experience in ion-conductive polymers, polymer synthesis, water-based slurries, battery electrochemical processes, thin-layer and surface phenomena, and particle coating.

The BIRD Energy funded project will enable NEI and 3DBattery to merge their disparate, yet complementing, technologies and capabilities toward a common goal of advancing the state of the art of Lithium-ion battery technology. The team has adopted a Systems Approach, wherein advances in materials and processing are integrated so as to deliver high performance in practical batteries.

“We are proud to support the project between 3DBattery and NEI Corporation to develop cathode and ion-conductive polymers that will lead to improved lithium ion batteries,” said Dr. Eitan Yudilevich, Executive Director of BIRD Foundation. “The BIRD Foundation will continue to support innovative projects that develop solutions for present and future challenges.” Mr. Erez Schreiber, CEO of 3DBattery Company, believes that cross-border partnership will be a key enabler in advancing the business interests of the company while focusing in technology development in Israel. 

Dr. Ganesh Skandan, CEO of NEI Corporation, said, “This is our first ever program through the BIRD Foundation, and we are excited to be working with 3DBBattery, who has a unique approach to ion-conducting binder materials, as well as anodes.”

3DBattery and NEI Corporation expect to roll out the first generation of their respective anode and cathode products by the end of the first quarter of 2021. The products will be optimized while the production is scaled through the rest of 2021.
