Preface
In the global solid-state battery race, a lithium-sulfur battery startup from Silicon Valley in the US is rapidly rising with a unique "dip-buying acquisition" strategy. Lyten, through successive acquisitions of core assets from the bankrupt European battery giant Northvolt, has secured 16 GWh of existing capacity, Europe's largest battery R&D center, and over 100 GWh of expansion space at a significant discount to valuation. Meanwhile, Lyten's lithium-sulfur battery technology, built on its patented 3D Graphene platform, completely eliminates nickel, cobalt, manganese, and graphite in its material system, carving out a technological path fundamentally different from traditional solid-state batteries.
On July 1, 2026, Lyten, a global leader in the battery and energy storage sector, announced the signing of an exclusive memorandum of understanding (MoU) to acquire Northvolt Drei assets located near Heide, Germany. The MoU was jointly signed by Lyten, KfW (German state-owned development bank), Northvolt Drei Project GmbH, and its shareholder LG Batterie GmbH.

Northvolt Drei, formerly owned by Northvolt AB, is a battery gigafactory project under construction covering 110 hectares, with considerable site preparation and the installation of electricity and utilities already completed. Under the MoU and an exclusivity agreement with the government of Schleswig-Holstein, Lyten will bear costs related to asset maintenance and employee salaries. All parties are working toward signing a final sale agreement in Q3 2026, with the transaction subject to customary regulatory and closing conditions.
Lyten CEO and co-founder Dan Cook stated, "We are very pleased to formally take the next step in completing the acquisition of Northvolt Drei assets. Europe has entered a period of sustained infrastructure investment growth, with power demand from electrification, AI data centers, and national defense driving long-term expansion. We plan to develop Drei into a clean battery and industrial manufacturing hub in Germany, synergized with AI infrastructure. The site benefits from abundant renewable energy and exceptional regional talent. This is a multi-decade strategic asset for Lyten."
Over the past 12 months, Lyten has completed acquisitions of multiple former Northvolt assets in Europe, including Northvolt Ett in Skellefteå, Sweden (one of Europe’s largest battery manufacturing sites), Northvolt Dwa in Gdańsk, Poland (one of Europe’s largest BESS manufacturing sites), and Northvolt Labs in Västerås, Sweden (one of Europe’s largest battery R&D centers).
The following concerns Lyten’s solid-state battery layout. This article will systematically outline Lyten’s strategic deployment in next-generation batteries from dimensions such as technology roadmap, product performance, capacity planning, company background and partnership dynamics.
1. Technology Roadmap
Lyten pursues a lithium-sulfur battery technology route, which differs significantly from conventional solid-state batteries (sulfide/oxide all-solid-state) in material systems and electrolyte form.
Lyten’s core technology is its proprietary “Lyten 3D Graphene” platform. The technical principle of this platform is to convert greenhouse gases into solid carbon and hydrogen, in which the carbon is permanently sequestered in the form of a three-dimensional metamaterial—3D Graphene. This 3D graphene features a tunable hierarchical pore structure spanning nano-, micro- and meso-scales, serving as an ideal host for the sulfur cathode. It physically confines sulfur and its intermediate polysulfides, effectively suppressing the “shuttle effect” common in lithium-sulfur batteries.
In terms of battery material systems, Lyten’s lithium-sulfur battery completely eliminates nickel, cobalt, manganese and graphite used in conventional lithium-ion batteries, instead adopting sulfur—abundant, low-cost and environmentally friendly—as the cathode material. The theoretical energy density of lithium-sulfur batteries reaches up to 2,600 Wh/kg, far exceeding the theoretical limit of conventional lithium-ion batteries.
Lyten’s 3D Graphene platform is highly tunable, enabling customization at the molecular level to meet specific battery application requirements—improving energy density, enhancing temperature performance, and achieving 20-minute fast charging. Beyond batteries, the platform is also widely applied in sensors, composites, adhesives and other fields.

2. Battery Introduction
The core advantages of Lyten’s lithium-sulfur battery lie in its fundamental material system innovation and high energy density potential.
Chart: Core Performance Indicators

Compared with mainstream lithium-ion batteries, Lyten’s lithium-sulfur battery can double energy density while significantly reducing battery weight. In terms of lightweighting, lithium-sulfur batteries using 3D Graphene can cut battery weight by 50% and reduce ore mining requirements by 85%. Supply side, this technology can be produced using localized, low-cost, and resource-abundant material supply chains.

In terms of safety performance, Lyten’s lithium-sulfur battery has demonstrated excellent characteristics in safety testing. Regarding temperature adaptability, the battery features a wider operating temperature range.
In terms of application positioning, given the lengthy battery certification process in the automotive industry, Lyten adopted a diversified client strategy, shifting its market focus to AI data centers, national defense, and industrial applications, rather than focusing solely on EVs.

3. Planned Capacity
Lyten’s capacity layout features a dual-engine approach of self-built and acquired capabilities:
3.1 Nevada Gigafactory (Self-built)
In October 2024, Lyten announced an investment of over $1 billion to build the world’s first lithium-sulfur battery gigafactory near Reno, Nevada, planned to start operations in 2027 with an annual capacity of 10 GWh.
3.2 Acquisitions: Northvolt Asset Acquisitions (Dip-buying Expansion)
Through a series of acquisitions, Lyten obtained Northvolt’s core assets at a steep discount far below their valuation:
November 2024: Acquisition of Northvolt’s aviation battery plant Cuberg in California, US.
Early July 2025: Acquisition of Europe’s largest battery energy storage system (BESS) production site — Northvolt’s Dwa plant in Poland.
