We love it when our startups achieve new milestones! 

NOVA by Saint-Gobain portfolio company, Ion Storage Systems, became the first U.S.-based solid-state battery technology company to achieve customer qualification of its Cornerstone™ cell performance! 

This is a major milestone validating ION’s patented solid-state battery technology! 

Production is scheduled to begin this year at its Maryland, USA, facility, with further scale-up already in the pipeline. 

Way to go, ION!
