Advancements in SOLiTHOR’s Lithium Solid-State Batteries for Maritime Industries

SOLiTHOR has made significant advancements in the development of its lithium solid-state batteries, specifically designed to facilitate the electric transition in the aviation and maritime industries. These advancements include enhancements in cyclability, energy density, and readiness for industrialization. Recent testing of SOLiTHOR’s pouch cells under specific conditions has demonstrated impressive results, with 1,000 full charge-discharge cycles achieved at a high coulombic efficiency of over 99.2%. This testing focused on endurance, a crucial aspect for long-lasting applications in aviation and maritime sectors.

The company’s innovative technology combines a thin Gen-1 solid electrolyte with thin lithium metal and high-loading nickel-manganese-cobalt (NMC) cathodes, resulting in a specific energy of 384 Wh/kg and energy density of 1,026 Wh/l at the stack level. These values are significant for industries that demand lighter, safer, and more powerful batteries. SOLiTHOR’s solid-state technology is fully compatible with commercial cathode components from the lithium-ion battery industry, enabling cost-effective industrialization of its products using existing production lines.

SOLiTHOR has already manufactured 3 Ah pouch cell prototypes and is conducting internal performance and safety testing. The company plans to send these prototypes for external validation and testing at aviation and maritime manufacturers in the near future. CEO Huw Hampson-Jones emphasizes the importance of high power and energy requirements in aviation and maritime applications, expressing a long-term goal to collaborate with battery manufacturers for mass production to meet the needs of aviation and maritime clients.
