SOLiTHOR has made advances in the development of its lithium solid-state batteries, designed to help the aerospace and marine industries accelerate their energy transition.
Recent developments include improved cycling, energy density and industrialization readiness.
Recent testing of SOLiTHOR pouch cells, conducted at a moderate temperature of 25° C and an external pressure of less than 72 psi/4.9 atm, resulted in 1,000 full charge cycles with coulombic efficiencies above 99.2 %. The test measures endurance, which is a critical requirement for long-duration aircraft and marine applications.
The company's solid Gen-1 electrolyte combined with thin lithium metal and heavily loaded nickel-manganese-cobalt (NMC) cathodes produces a specific energy of 384 Wh/kg and an energy density of 1,026 Wh/l at the stack level found in a different set. of cells. These gravity values are important for the aviation and marine sectors, which require light, safe and high-power batteries.

SOLiTHOR's solid-state technology is fully compatible with commercial cathode components produced in the lithium-ion battery industry. This will enable rapid development of its products in the coming years by using low-cost lithium-ion battery production lines, according to the company.
SOLiTHOR has developed 3 Ah pouch cell prototypes, using its internal operating principles and safety testing. Its short-term plan is to send those prototypes for external validation and testing to aircraft and marine manufacturers.
“Aviation and naval vessels require high power and high power to provide the electricity needed to safely transport aircraft and ships over long distances. One of SOLiTHOR's long-term goals is to work with battery manufacturers to mass produce cells for both our aviation and marine clients,” said Huw Hampson-Jones, the company's chief executive.
