High Performance Battery (HPB) and ZNL Energy have signed a memorandum of understanding (MoU) at the Future of Batteries (FOB) Summit in New York to collaborate on next-generation solid-state battery technology. The agreement outlines the integration of ZNL’s NPx separator into HPB’s inorganic solid-state battery development, with the goal of improving safety, energy density and manufacturability.
Since March 2024, HPB and ZNL have conducted joint testing of the NPx separator in prototype cells. Early results indicate that cells featuring the NPx material have sustained more than 4,500 charge–discharge cycles at a 1C rate (2.5–3.6 V, 25 °C). Compared to the glass separators used previously, the thinner NPx design offers potential gains in volumetric energy density and simpler handling during series-production processes.
Dr. Sebastian Heinz, CEO of HPB, stated, “ZNL’s separator has demonstrated strong compatibility with our solid-state chemistry in internal trials. We are now moving from laboratory validation into real-world testing and preparing for global production readiness.” Marcus Andreas Olsen, Business Development Manager at ZNL Energy, added, “Our collaboration aligns advanced separator technology with HPB’s solid-state platform and accelerates the path from lab-scale success to commercial impact.”
Under the terms of the MoU, ZNL Energy will supply lab-scale NPx separator samples for continued testing and prototype cell fabrication at HPB’s facilities. HPB will lead integration efforts and engage with its global licensee network to support future scale-up. Both organizations will focus on joint technical validation, optimization and pre-commercial trials aimed at applications in electric vehicles and stationary energy storage.
