Lyten ships Li-S battery A-samples for customer evaluation

Lyten has announced it has shipped A samples of its 6.5 Ah (C/3 discharge rate, 25° C) lithium-sulfur pouch cells to Stellantis and other leading US and EU automotive OEMs for evaluation. Lyten is known for using Li-S cathode made of sulfur and its proprietary 3D Graphene, sourced by capturing carbon from methane. This is said to eliminate the need for critical minerals like nickel, cobalt, and manganese in the cathode. The Li-S anode is a lithium metal composite, eliminating the need for graphite. The Company explaines that elimination of critical minerals means a projected 65%+ lower carbon footprint than lithium-ion batteries and a supply chain that can be fully sourced in the US or EU at scale.

Lyten manufactures lithium-sulfur cells in both pouch and cylindrical formats (2170 and 18650) and is currently shipping the 6.5 Ah pouch cell format for customer evaluation. Later this year, Lyten plans to deliver cylindrical A samples for evaluation. Lyten’s lithium-sulfur format flexibility enables its use in a wide range of industries beyond automotive, including space, aerospace, drones, micromobility, defense and consumer electronics.


Lyten has already shipped samples to a major US consumer electronics company, plans to deliver cells to the Department of Defense in May, and targets delivery of samples to more than 20 potential customers for commercial evaluation in the 2Q and 3Q 2024. Lyten is currently on target to deliver commercial use cells to aerospace and defense customers this year.

“This milestone is the result of years of dedicated work and innovation from the Lyten team, and we are just at the start of further expanding the capabilities of our lithium-sulfur battery cells,” said Dan Cook, Lyten CEO and Co-Founder.

The lithium-sulfur A samples are produced on Lyten’s automated pilot line in San Jose, CA, which opened in May 2023. The pilot line is built with standard lithium-ion equipment and manufacturing practices, proving the scalable manufacturability of Lyten’s lithium-sulfur cells. The San Jose production line will deliver B samples for Auto OEMs and commercial cells for smaller quantity, non-EV customers. Lyten’s first giga-scale facility is currently being designed with Turner Construction and SSOE to manufacture automotive C samples and beyond.

“The world needs a practical, mass market battery, and that is what we are building with our lithium-sulfur technology,” stated Celina Mikolajczak, Chief Battery Technology Officer at Lyten. “Mass market electrification and net zero goals demand higher energy density, lighter weight, and lower cost batteries that can be fully sourced and manufactured at massive scale using abundantly available local materials. That is Lyten’s lithium-sulfur battery.”

Lyten has raised more than $410M in equity capital to date, including investments from Stellantis, FedEx, Honeywell, Walbridge, and Prime Movers Lab. In February 2024, Chrysler announced the inclusion of Lyten’s Li-S batteries in its Halcyon concept EV.
