AM Batteries' direct powder deposition method proves commercially viable as 70+ industry leaders witness 20 m/min production speeds
BILLERICA, Mass., Oct. 28, 2025 /PRNewswire/ -- AM Batteries (AMB) demonstrated commercial-scale dry electrode manufacturing using its proprietary dry deposition method to over 70 industry leaders during Demo Day, proving the technology delivers the cost savings and performance needed to accelerate EV adoption and strengthen domestic battery manufacturing.
Major automakers, cell manufacturers and material suppliers from Japan, Korea, China, Europe, and the United States attended, bringing together key decision-makers from across the industry. The event included live production demonstrations of two pilot lines operating at commercial speeds, hands-on testing sessions, and deep dives with AMB leadership.
Industry Leaders Confirm Dry Deposition is the Future
Professor Shirley Meng, a leading battery researcher, delivered the keynote "Dry Electrode Architecture Design for Pushing Energy Density Limits at Cell Level." "The shift from wet to dry electrode manufacturing is inevitable and necessary for the industry," said Professor Meng.
Joe Lam of ATL (Amperex Technology Limited), one of the world's largest cell manufacturers, provided a customer testimonial detailing ATL's rigorous technology evaluation process. "ATL set up a dedicated team to vet all dry electrode processes across the world," said Lam. "We decided to partner with AM Batteries because their dry deposition technology was the most advanced, we had seen in our research."
Two Operational Lines Demonstrate Commercial Readiness
During the live demonstration session, guests observed two Engineering Pilot Lines (EPLs) in operation. EPL 1 ran continuously at 20 meters per minute, demonstrating that dry deposition can achieve the consistent, high-quality output required for commercial battery production. Guests also toured the Customer Success Center, where EPL 2 demonstrated customer material testing capabilities in a state-of-the-art dry room environment.
The dry room enables customers to test various materials, including moisture-sensitive high-nickel cathode materials, under controlled conditions before equipment purchases. Attendees tested AMB's interactive Technoeconomic Savings Calculator, which models dry deposition economics against conventional slurry coating. A 30 GWh gigafactory could save over $100 million annually by switching to AMB's technology.
Superior Technology Delivers Measurable Advantages
AMB's dry deposition approach deposits powder materials directly onto current collectors and compresses them in a single continuous process. Unlike extrusion-based dry methods that create free-standing films requiring additional lamination steps, AMB's direct deposition enables both thick and thin coatings and immediate powder recycling. The process eliminates the toxic solvents, extensive mixing equipment, and energy-intensive drying ovens that make conventional wet coating costly and environmentally harmful.

DEMO DAY BY THE NUMBERS
"Multiple tier-one manufacturers examined our technology for four hours and witnessed our direct powder-to-current collector process operating at commercial speeds with greater flexibility than competing approaches," said Lie Shi, CEO of AM Batteries. "We're now scaling globally to meet demand."
AMB is backed by strategic investors from the automotive, electronics, and energy sectors and has raised $74 million to date to commercialize its Powder to Electrode™ technology globally.
