Highstar Sodium Completes New Equity Financing; 6GWh Neijiang Sodium-ion Battery Plant to Start Production in Late October 2026
Highstar Sodium Technology Co., Ltd. (“Highstar Sodium”) has completed a new round of equity financing, welcoming three industrial and financial investors: Renshou Innovation Industrial Investment Fund (Limited Partnership), Chaowei Holding Group Co., Ltd., and Guizhou Chuanheng Chemical Co., Ltd. The company’s registered capital has increased from RMB 24.3 million to RMB 28.3 million. Ranked among the global top 5 sodium-ion battery manufacturers, Highstar Sodium is entering the final commissioning sprint at its 6GWh sodium-ion battery base in Neijiang, Sichuan, with mass production scheduled to launch in late October 2026.
1. Strategic Investors Join — Estimated Round Size of RMB 120 Million
After the capital increase, Renshou Innovation Industrial Investment Fund holds 11.7786% of shares and becomes the company’s 3rd largest shareholder. Chaowei Holding Group and Chuanheng Chemical each hold 1.1779%, ranking as the 8th largest shareholders.
In its 2026 semi-annual report, Chuanheng disclosed that it invested RMB 10 million of its own funds to subscribe to RMB 333,300 of Highstar Sodium’s new registered capital. Based on this valuation, industry estimates put the total financing of this round at approximately RMB 120 million. The entry of battery-industry capital and an upstream phosphate-chemicals company strengthens Highstar Sodium’s supply-chain security, capacity expansion, and go-to-market channels.
2. A Global Top-5 Sodium-ion Battery Maker on the NFPP Polyanion Route
Founded in March 2025, Highstar Sodium specializes in sodium-ion battery R&D and industrialization as a high-tech enterprise integrating R&D, intelligent manufacturing, and full-scenario services.
Leveraging its mature NFPP (sodium iron phosphate) polyanion technology route, Highstar Sodium’s sodium-ion battery shipments rank among the global top 5. The platform delivers three core strengths — high safety, high rate capability, and a wide operating temperature range — supported by one-stop solutions from cell development through energy storage system (BESS) integration.
3. Mass-Production Portfolio: Three Flagship NFPP Sodium Cells
Highstar Sodium’s factory has achieved series production of multiple NFPP sodium-ion cells:
- 50Ah prismatic sodium-ion cell
- 160Ah large-format prismatic sodium-ion cell
- 15Ah large cylindrical sodium-ion cell
All main products have passed UL, TUV, and IEC certifications for global market access. The self-developed NFPP sodium cells and battery systems are deployed worldwide across:
- Grid & commercial-industrial energy storage
- Telecom base station backup power
- AIDC data center UPS power
- Automotive start-stop power systems
- Special vehicle power systems
Overseas energy storage module orders are in continuous batch delivery, and a domestic 30 MWh sodium-ion battery storage project has been successfully commissioned.
4. 6GWh Neijiang Plant: Commissioning Sprint, Launch in Late October 2026
Highstar Sodium’s 6GWh annual sodium-ion battery manufacturing base in Neijiang, Sichuan is now in the final equipment commissioning phase, with mass production scheduled to launch in late October 2026.
The base focuses on intelligent production lines for large cylindrical and large-format prismatic sodium cells. Once operational, the 6GWh plant will significantly expand Highstar Sodium’s NFPP cell delivery capacity, reinforce its position as a global top-5 sodium-ion battery supplier, and better serve bulk orders from energy storage and industrial power customers worldwide — accelerating the commercialization of sodium-ion batteries.
5. Why Sodium-ion Batteries Are Scaling Now
With abundant raw materials, excellent low-temperature performance, and superior safety, sodium-ion batteries are gaining rapid adoption in stationary energy storage and backup power markets. The newly closed financing and the upcoming 6GWh production line will further strengthen Highstar Sodium’s R&D and manufacturing base, supplying reliable sodium cells and battery systems for customers worldwide.
