SufroN

Sulfur at Scale: A By‑Product Ready for Circular Reuse

SufroN is a deeptech startup developing a new generation of room‑temperature sodium–sulfur batteries. We combine abundant elements with circular‑economy carbon to unlock safe, scalable, and cost‑effective energy storage.

Room‑temperature sodium–sulfur batteries.

We design and optimize RT‑Na/S cells that operate safely at ambient conditions, avoiding the complexity and risks of high‑temperature systems.

Abundant, circular‑economy inputs

Our chemistry is built on widely available sodium and sulfur, enhanced with carbon derived from local biomass residues.

Licensing‑first industrial deployment

We develop the core technology and license it to industrial partners, enabling rapid, capital‑efficient scale‑up.

For Partners

We collaborate with industrial groups, research labs, and regional ecosystems to scale room‑temperature sodium–sulfur technology.

Why Now

Strategic Need for Alternatives

Europe and other regions are seeking complementary chemistries to strengthen energy sovereignty.

Abundant Sodium & Sulfur

These elements are globally available, low‑cost, and already handled at industrial scale.

Lithium Supply Constraints

Global demand for lithium‑ion batteries is creating material bottlenecks and cost volatility.

Circular‑Economy Opportunity

By integrating biomass‑derived carbon, SufroN connects energy storage with local circular‑economy value chains.

Our cells use sodium as the anode and sulfur‑based composites as the cathode, engineered to operate safely at room temperature.

Circular Carbon Materials

We convert local agricultural residues into high‑performance carbon materials that enhance electrode performance.

Safety & Sustainability

Our approach avoids critical raw materials and targets safer, more sustainable energy storage.

Applications

Designed for stationary and industrial storage, where cost, safety, and lifetime matter most. This chemistry is optimized for long‑duration, safe, cost‑stable storage — ideal for grids, industry, and renewable integration.

Room‑Temperature Sodium–Sulfur Chemistry

From Lavender Fields to Battery Materials

We transform local agricultural residues into high‑value carbon materials, creating a unique circular‑economy pathway.

Step 1 — Lavender to Perfume

Lavender is cultivated and distilled to produce essential oils.

Step 2 — Residual Biomass

Stems, leaves, and spent flowers remain after extraction.

Step 3 — Carbonization

We convert this biomass into functional carbon materials through controlled thermal processes.

Step 4 — Battery Integration

These carbons are integrated into our sodium–sulfur electrodes, turning local waste into strategic energy‑storage materials.

0–12 Months — Foundation

Pre‑incorporation, lab setup, first RT‑Na/S prototypes, baseline performance.

12–24 Months — Validation

Performance optimization, demonstrator cells, IP consolidation, and early industrial discussions.

24–36 Months — Pilot & Partnerships

Pilot‑scale validation, adaptation to partner manufacturing lines, licensing framework.

36+ Months — Scale Through Licensing

Multi‑partner industrial deployment aligned with European sovereignty goals.
