Lyten, has introduced its LytCell EV lithium-sulfur (Li-S) battery platform. The Lyten 3D Graphene-based Li-S architecture has the potential to reach a gravimetric energy density of 900 Wh/kg. LyctCell batteries utilize Lyten Sulfur Caging to unlock the performance potential of sulfur by arresting the poly-sulfide shuttle – a cycle-life compromising factor that previously prevented practical Li-S use in battery electric vehicles. Under DOD test protocols, a prototype version of LytCell demonstrated greater than 1,400 cycles.
Critical to Lyten’s battery breakthrough was the development of Lyten 3D Graphene, a three-dimensional graphene material platform. It can be engineered and tuned at the molecular level to specific battery application requirements. The Lyten 3D Graphene platform enables Lyten’s advanced lithium-sulfur battery chemistry to realize exceptional levels of energy density, temperature performance, charging and safety.
Li-S does not contain oxygen from metallic oxides, which is what drives thermal runaway events that have been detrimental to many EVs.
Lyten’s new battery platform offers a number of advantages to automakers and their customers, including a reduction in cost parity against ICE vehicles. It is also capable of safely, and effectively, operating in environments from -30 degrees Celsius to 60 degrees Celsius – reducing system level costs. Its flexible, scalable, pack sizing allows Lyten to adapt to a variety of automotive platforms, and can be produced in cylindrical, pouch and prismatic formats. Other benefits include on-shore cell manufacturing facilities proximate to OEMs, extended range and increased payloads, faster charging times and enhanced sustainability while avoiding the use of conflict materials.
Lyten expects full production and market availability for ‘25-‘26 MY vehicles.
