ION Storage Systems Invests in Scalable Pilot Sintering Furnace to Accelerate Solid-State Battery Production
Investment enables future scaling to hundreds of MWh and deepens customer sampling capabilities
BELTSVILLE, Md., May 28, 2025 /PRNewswire/ – ION Storage Systems (ION), a leading innovator in next-generation solid-state battery (SSB) technology, announced that it has invested in a new pilot production ceramic sintering furnace at its Beltsville, MD facility. The advanced equipment is intended to increase ION’s annual ceramic production capacity by ~1,000x and unlock the ability to rapidly scale to hundreds of megawatt-hours (MWh) through future expansion.
Sintering is critically important as a major processing step in forming ION’s proprietary and high-performing ceramic electrolyte, which is the core of its solid-state battery technology. ION’s investment in this new equipment represents another major commercialization milestone that will position the company to significantly ramp up the delivery of its patented solid-state battery cells for customers across market segments.
Dr. Greg Hitz, Co-Founder and CTO of ION Storage Systems, said:
I am excited for our new sintering furnace, as it gives us a clear path to reach commercial scale as well as serve as the launchpad for future expansion,
“We will have the infrastructure in place to deliver our current footprint as well as expand to large-format solid-state batteries, accelerating our ability to meet growing demand from OEMs, integrators, and government partners across market segments like consumer electronics and EV.”
ION’s proprietary ceramic solid-state platform is based on a compressionless, anodeless, and 3D-structured architecture, eliminating the high-pressure packaging constraints that have historically hindered the adoption of solid-state batteries. The new advanced process equipment is specifically designed to support this architecture, optimizing the sintering process to produce high-performance ceramic electrolyte without compromise at scale.
Unlike conventional solid-state designs that require pressure to maintain contact between layers, ION’s zero-compression approach enables modular and scalable stacking, leading to improved safety, manufacturability, and design flexibility for a wide range of energy storage applications.
This investment follows ION’s successful production of multi-layer solid-state battery cells on its semi-automated manufacturing line, marking another critical step in scaling its compression-free architecture toward full commercialization.
Hitz, added:
As we continue to prove out both performance and scalability, this new production capability will allow us to meet our customers’ demand head-on,
“It’s the next step in our mission to power a limitless future with long-lasting, safe, and practical batteries.”
