Sulfur as Key Ingredient for Affordable, Enhanced Batteries

Lyten has made significant advances in extending the lifespan of its batteries, with some samples attaining up to 300 cycles. A key factor in this achievement is the company’s use of 3D graphene material, which inhibits undesirable side reactions and enhances the battery cell’s energy density. Beyond batteries, Lyten is also exploring the application of 3D graphene in other components like sensors and composites.

Yet the journey to develop batteries capable of powering electric vehicles (EVs) is far from completion. In the interim, Lyten intends to introduce its cells in markets where a long lifetime is less crucial.

As lithium-sulfur batteries have the advantage of being extremely light, Lyten is collaborating with clients who create devices such as drones, where the weight saving compensates for the need to frequently replace batteries. This insight comes from Keith Norman, Lyten’s chief sustainability officer.

In 2023, Lyten started a trial production line with a potential maximum output of 200,000 cells annually. The company has recently begun to produce a limited number of cells, which are planned for distribution to customers later this year, although it has not publicly announced the recipients of the first batteries.

Looking ahead, Lyten’s primary goals include prolonging the battery lifespan and increasing the quantity of both 3D graphene and battery cells. As Norman pointed out, the path to lithium-sulfur batteries suitable for EVs is lengthy. Nonetheless, just as lithium-ion has significantly improved in cost, lifespan, and energy density over the years, so too can new technologies with dedicated research and development. To realize any new chemistry in batteries, a significant amount of effort must be invested.
