Green New Energy Materials Inc. (GNEM) develops advanced battery separators for lithium-ion batteries, aiming to improve safety, efficiency, and performance in EVs and consumer electronics. Founded in 2023, GNEM tackles energy storage challenges by designing separators that lower thermal runaway risks, reduce energy loss, and extend battery life. Prioritizing U.S. manufacturing, the company supports energy independence and promotes clean energy adoption.
Headquartered in North Carolina, GNEM supplies major battery-sector clients, including Tesla, Volkswagen, Ford, LG, Samsung, and Northvolt. Its Denver, North Carolina, facility—the first in North America—strengthens regional supply chains and addresses rising demand for EVs and energy storage. By leveraging innovative technology and scalable production, GNEM helps reduce reliance on fossil fuels and accelerate the shift to cleaner energy systems.
Battery Technology
GNEM’s core innovation lies in its advanced battery separators, which form the structural and functional backbone of high-performance lithium-ion batteries. These separators are ultra-thin (around 5 micrometers thick) yet durable, enabling higher energy density while minimizing electrical resistance. The separators’ enhanced thermal stability mitigates risks of overheating or fire—critical factors for safe battery operation.
GNEM’s materials innovations have been integrated into automotive, grid-scale, and consumer markets, with separators supplying major manufacturers. For example, their separators reduce downtime risks for EVs while supporting utilities’ demand for longer-lasting energy storage systems.
GNEM’s separators also reduce reliance on imported components by sourcing materials and maintaining domestic production in the U.S., supporting broader climate goals. The company’s materials are tailored to the specific needs of varied markets: energy grids require stable, long-term storage, while EVs depend on lightweight, durable separators.
Recent Projects
A major milestone in 2024 was GNEM’s announcement of a $140 million manufacturing plant in Denver, North Carolina, set to begin operations in 2025. Expected to employ 545 workers and generate $1.15 billion in economic impact by 2037, the facility positions the U.S. as a leader in high-quality battery components. The plant’s production is projected to boost local supply chains for EV and energy companies like Tesla and Northvolt.
The company also expanded partnerships with automotive and energy firms in 2024, further integrating its separators into next-generation battery cells. Collaborations with organizations like the National Renewable Energy Laboratory may also underpin upcoming research into next-gen separators for solid-state batteries.
