SOLiTHOR, a solid-state battery developer, has made significant advancements in battery technology that could revolutionize the electric transformation of the aviation and maritime industries. Their lithium metal solid-state battery prototypes have shown exceptional performance in testing, completing 1,000 full charge-discharge cycles with a coulombic efficiency exceeding 99.2 percent. These tests, conducted under controlled conditions, surpassed commercial performance targets.
The company’s innovative technology combines a thin proprietary solid electrolyte with lithium metal and high-loading cathodes, resulting in unprecedented energy densities of 384 watt-hours per kilogram and 1,026 watt-hours per liter at the stack level. Dr. Fanny Bardé, SOLiTHOR’s Chief Technology Officer, emphasized the significance of achieving such high cyclability in a solid-state configuration, a goal that has been pursued for decades by researchers.
One key advantage of SOLiTHOR’s technology is its compatibility with existing lithium-ion battery production lines, potentially enabling rapid industrialization with minimal additional cost. The company has already developed 3Ah pouch cell prototypes and plans to collaborate with industry partners for external validation. CEO Huw Hampson-Jones highlighted the importance of high power and energy solutions for electrifying aviation and maritime transportation, emphasizing the company’s capabilities in meeting these demands.
SOLiTHOR’s breakthrough in battery technology addresses critical challenges in electric transportation, offering lighter, safer, and more powerful solutions essential for aircraft take-off and landing operations. Unlike current battery technologies, their approach promises superior energy density and long-term cycling stability. The company’s focus is on partnering with battery manufacturers to scale production for aviation and maritime clients, positioning itself as a leader in electric transportation technology.
