SOLiTHOR Reaches 1000 Charging Cycles with over 80% capacity retention, a Key Milestone in its Development of Solid-State Batteries for the Aviation and Maritime Sectors
PUBLISHED 29 OCTOBER 2024

SINT-TRUIDEN (Belgium) – 29th October 2024 - SOLiTHOR has made significant progress in the development of its next-generation Lithium metal solid-state batteries (SSBs) designed to meet the rigorous demands of the aviation and maritime industries and accelerate their electric transition. These advancements include major improvements in cyclability, energy density, and industrialisation readiness, making SOLiTHOR one of the world’s leaders in the solid-state battery sector.

Recent testing of SOLiTHOR’s pouch cells, conducted at a moderate temperature (25°C) and with external pressure (below 72 psi/4.9 atm), has resulted in 1000 full charge discharge cycles with a coulombic efficiency above 99.2 percent. Under these conditions, the test was done to measure endurance which is a key performance criteria for long-lasting aviation and maritime applications. The result was well above the accepted commercial target.

A standout feature of SOLiTHOR’s technology is the successful demonstration of the use of its thin proprietary Gen-1 Solid Electrolyte when paired with thin lithium metal and high-loading NMC cathodes.

This combination enables outstanding energy densities of 384 Wh/kg and 1,026 Wh/l at stack level obtained on a different set of cells. Such record-breaking gravimetric energy values are crucial to enable the electric transition of the aviation and maritime sectors which require lighter, safer and more powerful batteries particularly for take-off and landing.
