Lithium-Sulfur Batteries.
Electrify Everything.

No Graphite.

A battery simplified: A sulfur cathode with no nickel, cobalt, manganese, or other critical minerals. A lithium-metal anode with no graphite.

Ultra Lightweight.

High energy density cells designed to electrify anything that moves. Transportation. Aerospace. Micromobility. On a pathway to 2X the energy density of lithium-ion.

Local Materials. Local Manufacturing.

Using abundantly available materials to eliminate supply chain risk and costs. Manufacturing on standard lithium-ion equipment in use for decades. The result? A locally sourced, locally manufactured battery in the US, Europe, or across the globe.

The battery for mass market electrification

Lithium-Sulfur chart of energy density

Lithium-Ion battery chemistries have made electrification possible, but multiple barriers stand in the way of making mass market electrification with Lithium-Ion a reality: heavy dependency on mined minerals, supply chain constraints, costs, and thermal runaway risk.

Lithium-Sulfur has been known for decades as an extremely high energy density, lightweight chemistry that requires no nickel, cobalt, or manganese in the cathode, and no graphite in the anode, and an improved safety profile. But Lithium-Sulfur technology wasn’t expected to progress until the 2030’s — that is, until we developed Lyten 3D Graphene. We’re using our supermaterial to make the Lithium-Sulfur battery a reality — years ahead of schedule.

Energy density is just the start. Lyten’s Lithium-Sulfur can deliver a wide range of other improvements.

Higher performing: Targeting greater than 2 times the energy density (Wh/kg) of lithium-ion, creating a fundamentally lighter weight battery that operates over a wider temperature range.

Safer: Strong resistance to overcharge and puncture failure modes, without the use of oxides that can cause runaway thermal reaction.

100% locally sourced and manufactured: The removal of nickel, cobalt, and manganese from the cathode and graphite from the anode means a massively simplified supply chain, enabling battery manufacturing anywhere and a bill of materials 50% lower than lithium-ion.

Manufacturable using existing lithium-ion equipment: Only minor modifications required to convert to Lithium-Sulfur.

Lowest carbon footprint: Lyten’s Lithium-Sulfur architecture has been independently verified to have a greater than 60% lower carbon footprint than best-in-class lithium-ion.

What makes Lithium-Sulfur a gamechanger

Lithium-Sulfur Manufacturing

Lyten opened its first Lithium-Sulfur Pilot Production Line in May 2023 in San Jose, CA.  The semi-automated line produces both cylindrical (2170, 18650) and pouch cells. The manufacturing line utilizes standard lithium-ion equipment that was converted to Li-S in 2023 for ~2% of the original capex, proving the scalable manufacturing of lithium-sulfur.

We are now producing and delivering “A sample” cells. The same manufacturing line will also deliver automotive “B samples” and commercial cells to non-auto customers in aerospace, space, defense and more.
