What does a mass market battery look like?
Lightweight
Nobody hopes for a heavier world. The future is lighter, stronger, and more efficient. A higher energy density battery will translate into lightwe weight EVs, trucks, drones, satellites, and so much more.
Abundant
Sulfur is plentiful and low-cost, and most of the world’s supply is recovered as a by-product of oil and gas processing. Building batteries on sulfur, rather than opening new mines, is both cost-effective and lowers impact.
Localized Sourcing
We prioritize regionally sourced raw materials where possible, including abundant sulfur and natural-gas-derived feedstocks available almost anywhere. Cells are designed for local manufacturing worldwide, including the Global South.
No Mined Cathode Metals
Mining our way to more batteries is not going to cut it. Batteries made with abundant inputs like sulfur and 3D Graphene made from methane, with no nickel, cobalt, manganese, or graphite. That’s the formula for the next generation of batteries.
Low Cost
Forget cost parity. Mass-market electrification requires indisputably lower cost than internal combustion engine (ICE) vehicles. Lithium-Sulfur starts with lower-cost materials than LFP, and leaves behind the price swings of NMC and graphite.
Manufacturable
The next generation battery will be manufactured today’s gigafactories with today’s equipment. Scaling up means converting existing lines rather than building from scratch, harnessing decades of manufacturing learning and scale.
Lyten’s Lithium-Sulfur Architecture.
Powering Multiple Form Factors.
Lithium-Sulfur’s performance is perfect to electrify anything that moves. Lyten has begun the multi-year qualification process for EVs, Trucks, Delivery Vehicles, and Aviation. But, Lyten is also on target to deliver commercial ready batteries for Drones, Satellites, and Defense applications; and micromobility and mobile equipment.

Weight Matters.
When Less is More.
A sulfur cathode and lithium-metal anode have the potential to hold multiple times the energy density of current lithium-ion batteries.
Lyten uses that potential to build a practical battery without heavy minerals like nickel, cobalt, graphite, or iron and phosphorous. The result is an up to 50% weight reduction vs NMC and up to 75% weight reduction vs LFP.
Supply Chain Matters.
Easier Said Than Done.
Today, its not possible to buy a lithium-ion battery whose raw materials do not go through China. Instead of trying to rebuild the mining and processing supply chain, our mission is to simply eliminate it.
Lyten Lithium-Sulfur is designed for regional sourcing. Our cells contain no NMC or graphite, and since 2025 our U.S. sulfur has been domestically sourced. We prioritize domestic suppliers where feasible, and for lithium we’re exploring domestic brine extraction and recovery from our own scrap. Next up is Europe, where we now have cell manufacturing and energy storage operations, and where we aim to bring the same approach to Lithium-Sulfur.
Manufacturing Matters.
Drop In. But Easier.
The world can’t wait for a new chemistry requiring completely new manufacturing. The world is building gigafactories now. Lyten Li-S can be manufactured on the same equipment lines that fill gigafactories today. Well…almost. First, we can eliminate some of the equipment because we don’t need it!
Lyten Lithium-Sulfur’s automated pilot line in San Jose, CA was converted from a lithium-ion line for <3% of capital. That pilot line quickly ramped up to >90% yields for both pouch and cylindrical cells.
Cost Matters.
“I’d Like To Pay More” Said No One Ever.
Electrification is spreading across the world, touching everything from EVs and drones to trucks and heavy industry. Yet much of a battery’s cost still comes from a few mined metals refined in a handful of countries. Bringing that cost down starts with the materials.
Lyten is building a Lithium-Sulfur battery with higher energy density than NMC, but made from lower-cost materials than LFP.
Carbon Footprint Matters.
It Starts With The Materials.
The removal of mined nickel, cobalt, manganese and graphite is a great start. Add Lyten 3D Graphene, made from natural gas, and regionally-abundant Sulfur. Then, power your operations with renewable power, like Lyten’s San Jose manufacturing operations, which work in partnership with San Jose Clean Energy’s GreenSource program (60% renewable and 95% carbon-free).
The result is a Lithium-Sulfur cells with lower cradle-to-gate emissions than 28 battery chemistries surveyed across 11 peer-reviewed studies: 41 kg CO₂e/kWh using natural gas and grid electricity, against a surveyed mean of 119.
Cradle-to-gate emissions from 28 battery chemistries analyzed by 11 peer reviewed LCAs (Life Cycle Analysis) compared to LCA for Lyten Li-S battery. Third-party assessment completed by EcoEngineers, commissioned by Lyten, based on 2023 lab and demonstration-scale data. No ISO 14044 critical review; comparisons are to published LCAs with differing scopes and assumptions. The Lyten point shown assumes renewable natural gas and solar electricity (about 25 kg CO₂e/kWh).
