Zoolnasm (众钠能源) Raises Series A for Sodium-Ion Battery Expansion

Zoolnasm Closes Series A Round

Zoolnasm (众钠能源), a China-based sodium-ion battery developer, has raised a Series A round. The funding date is October 8, 2026. The company did not disclose the funding amount, lead investor, or participating investors.

What the Company Does

Founded in 2021 and headquartered in Suzhou, Zoolnasm works the polyanionic route for sodium-ion batteries, built around proprietary iron-sulfate-based (NFS) cathode materials. The company supplies cathode materials, cells, packs and systems, targeting light electric mobility and stationary energy storage applications.

Manufacturing Footprint

Zoolnasm operates a cathode material plant in Zhenjiang and a 10,000-tonne cathode plant in Meishan, Sichuan. That production base supports both its materials business and its downstream cell, pack and system offerings.

Positioning in the Sodium-Ion Sector

The company says its fundraising scale has led the global sodium-ion battery sector for two consecutive years. Sodium-ion technology has drawn attention as an alternative chemistry for applications where cost, supply-chain resilience, and safety considerations matter alongside energy density.

Round Summary

• Company: Zoolnasm (众钠能源)
• Round: Series A
• Amount: Not disclosed
• Currency referenced: CNY
• Date: October 8, 2026
• Lead investor: Not disclosed
• Investors: Not disclosed
• Sector: Sodium-ion batteries / cathode materials
• Founded: 2021
• Headquarters: Suzhou, China

Why It Matters

Zoolnasm's approach is vertically integrated relative to many battery startups: it develops the cathode chemistry, produces cathode materials, and supplies cells, packs and systems. The polyanionic, iron-sulfate-based NFS cathode route is the technical core of that stack.

Its two production sites — Zhenjiang for cathode materials and the 10,000-tonne Meishan facility in Sichuan — give the company manufacturing capacity to pair with its chemistry development. For light electric mobility and stationary storage, both of which are cost-sensitive segments, that combination is central to the commercial case.

What Comes Next

With a Series A in hand, the company's stated focus areas — cathode materials, cells, packs and systems across mobility and storage — remain the operating priorities. The company has not disclosed how the proceeds will be allocated, and no lead investor was named in the round details.

For those tracking the sodium-ion sector, Zoolnasm remains one of the more visible China-based players, with an established manufacturing footprint and a stated multi-year fundraising lead in the category.
