BTRY is a 2023 spinout developing ultrathin thin-film solid-state batteries that replace liquid electrolytes with solid materials to combine energy storage and high power delivery. The company employs a solvent-free vacuum roll-to-roll coating process derived from the semiconductor industry to enable scalable, cost-efficient production. BTRY targets applications across industrial use cases, the Internet of Things, medical technology, and wearable devices. It plans to industrialize its technology and establish what it describes as Europe’s first industrial plant for thin-film solid-state batteries, aiming to produce millions of units per year. The only financial detail reported in the article is the recent €2.2 million EIC Accelerator grant to support those plans.
