SOLiTHOR has achieved milestones in developing next-generation Lithium metal solid-state batteries (SSBs) tailored for the aviation and maritime industries to support their transition to electric propulsion.
These advancements include improvements in cyclability, energy density, and industrial readiness.
Recent tests on SOLiTHOR’s pouch cells at 25° C and under external pressure (below 72 psi/4.9 atm) demonstrated 1,000 full charge-discharge cycles with a coulombic efficiency exceeding 99.2%. These results, well above commercial targets, highlight the endurance required for long-lasting applications in aviation and maritime industries.
A key innovation is SOLiTHOR’s proprietary thin Gen-1 Solid Electrolyte, thin lithium metal, and high-loading NMC cathodes. This combination has achieved remarkable energy densities of 384 Wh/kg and 1,026 Wh/l at the stack level — critical for creating lighter, safer, and more powerful batteries required for applications like take-off and landing in electric aircraft and vessels.
SOLiTHOR’s solid-state technology is compatible with current commercial cathode components used in the Li-ion battery industry, enabling rapid industrialization by leveraging existing production lines. This compatibility minimizes costs and accelerates the transition to solid-state batteries.
As part of its roadmap, SOLiTHOR has successfully manufactured 3-Ah pouch cell prototypes that are undergoing internal performance and safety testing. These prototypes will soon undergo external validation and testing with aviation and maritime partners, advancing the commercialization of this transformative technology.
