ION Storage Systems, Inc. (ION), a company headquartered in Maryland that develops next-generation, solid-state battery technology. They have announced the commercial launch and initial shipment of Cornerstone, its first-generation Cornerstone multilayer solid-state battery cells. These next-generation batteries are being shipped to consumer electronics manufacturing giants all over the world to incorporate. Testing in products, such as smartphones, laptops, and wearables, among other small, powerful devices. Developed to address the decades-old need of the battery industry, Cornerstone delivers unmatched safety, high cycle life, and zero swelling. Further eliminating the bulky mechanical systems of compression, long been used to suppress solid-state adoption.

With the introduction of Cornerstone, there is a paradigm shift toward the ability to understand commercially viable solutions at the lab scale. The technology at ION is exceptional in that it offers stability and similar performance across applications since it has opened the way to the transformation of the industry. The platform of Cornerstone, due to the unique architecture and manufacturing process, offers higher energy density and provides better thermal stability and a long lifecycle. Such attributes render it perfectly suited to more than just consumer electronics, and also well-suited to electric vehicles (EVs), aerospace systems, and defense uses.

In the future, the strategic roadmap of ION is aimed at expanding production capacity, enlarging its list of customers, and achieving technological advancements in next-gen products. The company implemented the sampling programs, which are said to be the largest in the solid-state battery industry. They are aiming to delve into the market in consumer electronics, EVs, aerospace, and defense simultaneously. Furthermore, this kind of ambitious cross-industry move can make ION a cornerstone technology supplier in the worldwide energy storage ecosystem.

Executives’ Statements:

Jorge Diaz Schneider, CEO, ION Storage Systems:

“Cornerstone powers the most expansive solid-state sampling programs in the industry, reaching top-tier customers in consumer electronics, EV, aerospace, and defense simultaneously. Our platform is uniquely positioned for broad, multi-industry adoption.”

Eric Lind, Chief Commercial Officer, ION Storage Systems:

“The industry has been waiting for solid-state batteries to progress from lab-scale prototypes to commercially viable products. That inflection point is here with Cornerstone. According to our customers, we’re the only solid-state battery company currently delivering fully functional cells that don’t require compression for integration and testing in real-world consumer electronics. This achievement sets us apart in a highly competitive landscape. This testing is the first step toward rapid deployment into portable devices with significantly improved energy density, integration flexibility, thermal stability, and cycle life.”
