Addionics

Market position

Addionics describes itself as a global leader and the leading manufacturer of 3D current collectors, and as the first company with a scalable, cost-effective battery-grade production process for porous 3D current collectors covering both anodes and cathodes. A third-party startup directory lists total funding of $73 million and names Tesla, Northvolt and Verkor as competitors. Its investor base includes the corporate venture arms of General Motors and Scania.

Addionics differentiates by targeting cell architecture instead of active materials, describing itself as not betting on which chemistry wins. It claims to be the first company to unlock a scalable, cost-effective, battery-grade production process for porous 3D current collectors for both anodes and cathodes, with the manufacturing process itself as core IP. Additional stated differentiators are drop-in compatibility with existing coating and assembly lines without new equipment, chemistry and format agnosticism, an AI-driven design platform that configures architectures from a searchable configuration space rather than bespoke engineering per customer, and a patent position of 18 families, 47 filings and 9 grants as of 2026.

Technology

The core technology replaces flat solid metal foil current collectors with porous, ion-permeable copper and aluminum 3D structures. The porous structure creates through-plane pathways for lithium ions and electrolyte, shortens transport distances, lowers electrical and contact resistance, improves adhesion to allow thicker electrodes and higher active-material loading, and produces more uniform current, heat and electrolyte salt distribution. Stated production benefits include faster drying, faster electrolyte wetting, reduced formation gas, fewer electrode layers and dry-coating compatibility. Manufacturing uses a patented continuous roll-to-roll process based on commodity materials and established methods, validated across coating, drying, calendering, slitting and cell assembly. A patented AI platform applies structural modeling and machine learning to select the optimal current collector geometry for a given chemistry, cell format, use case and system-level requirement.

Go-to-market

Addionics sells to battery manufacturers and automotive OEMs, supplying current collectors for direct integration into customers' existing production environments and cell assembly processes. It emphasizes drop-in adoption and integration support, and at the time of its Series B said it was working with the majority of the ten largest global automotive OEMs and battery manufacturers, with partnerships across North America and Europe. Strategic investors including GM Ventures and Scania also serve as industry channels, and the company engages prospects around defined duty cycles and application-specific architectures.

Battery cell manufacturers and automotive OEMs, including large global automakers and battery producers. Application segments named by the company are robotics and humanoid/mobile robots, defense drones and UAVs, space platforms, electric and autonomous vehicle fleets including robotaxis and autonomous trucks, and data centre batteries through a partner.

Geography

As of the 2024 Series B announcement, Addionics had sites in the United Kingdom, Israel, the United States and Germany, with the funding announcement issued from London. Company web materials reference Tel Aviv. Partnerships were described as spanning major OEMs and automakers across North America and Europe, and the company has a production collaboration with a Korean battery manufacturer. It was also planning a US-based gigafactory for 3D current collector production.

History

The company was founded in 2017 and traces its origins to co-founder and CEO Moshiel Biton's research on the formation of metal dendrites, conducted as part of one of the first teams to observe the phenomenon via live video, roughly a decade before the current company materials were published. Addionics subsequently developed a patented, scalable manufacturing process for battery-grade Smart 3D Porous Current Collectors and states it is the first company to achieve a scalable, cost-effective production process for both anodes and cathodes. In July 2024 it announced a $39 million Series B co-led by GM Ventures and Deep Insight, with proceeds directed at manufacturing scale-up, global team expansion and a planned US gigafactory, and it said commercial production would begin by the end of that year. Later company materials describe a product line of validated architectures, a patent portfolio of 18 families and 47 filings as of 2026, and a production collaboration with Korean battery manufacturer PNT on batteries for data centres.

Risks & controversies

Performance figures shown in the company's cell-design material are noted as coming from an Addionics cell-design demonstrator supplied by Addionics and are stated not to be a product specification. The business also depends on scaling manufacturing, including a planned US gigafactory, and on adoption by large battery manufacturers and automotive OEMs.
