On June 18, 2026, ProLogium and Elysian Aircraft BV signed a Memorandum of Understanding to assess the integration of advanced battery technology in all-electric aircraft. ProLogium, a leader in next-generation lithium ceramic battery development, and Elysian, a Dutch aerospace company working on large-scale battery-electric aircraft and core electrification systems, will collaborate on both standard and custom validation of battery platforms for aviation use.
Their discussions will explore compatibility between ProLogium’s existing next-generation battery cells and typical aircraft battery systems. In parallel, the partners will consider bespoke cell designs tailored to aviation performance targets. Key objectives include developing battery modules and packs with pack-level energy densities ranging from 320 to 420 Wh/kg, which could support aircraft ranges of 750 to 1,000 kilometers. Project teams will evaluate how these higher-density cells might enhance weight efficiency, extend flight range, and increase operational flexibility compared to conventional lithium-ion batteries.
As the aviation sector pursues zero-emission solutions, energy density, safety, weight management, and system integration become critical. ProLogium’s solid ceramic separator architecture and all-inorganic battery chemistry have demonstrated high energy density and robust safety characteristics in ground transportation applications. Elysian’s E9X electric aircraft program, meanwhile, aims to validate scalable electrification technologies for commercial aviation.
Beyond technical performance, the partners will assess opportunities to localize battery supply chains in Europe. By leveraging regional manufacturing capabilities, they intend to shorten logistics routes, bolster resilience, and lower life-cycle greenhouse gas emissions.
Vincent Yang, ProLogium’s CEO, commented that “aviation demands rigorous assessment of energy density, safety, and weight efficiency,” while Elysian’s Co-CEO and CTO, Rob Wolleswinkel, noted that “next-generation battery technology is essential for safe, scalable, zero-emission flight.” This MoU sets the groundwork for future cooperation on energy transition and sustainable aviation mobility.
