China's vanadium electrolyte industry is undergoing an unprecedented wave of expansion, driven by the accelerating deployment of long-duration energy storage systems and the rapid commercialisation of vanadium flow batteries (VFBs). According to statistics compiled by ASIACHEM Consulting, China now has more than 20 operational vanadium electrolyte projects, with total fully-utilised production capacity already exceeding 600,000 m³ per year.
At the same time, announced, planned, and under-construction projects now exceed 4.5 million m³ per year of additional vanadium electrolyte capacity, highlighting the extraordinary scale of investment flowing into the sector and reinforcing China’s position as the global centre of the vanadium flow battery supply chain.
Major Industry Expansion Driven by Leading Producers
Rongke Power remains the world’s largest vanadium electrolyte manufacturer. Its subsidiary Dalian Borong reached annual production capacity of 150,000 m³ following completion of a major expansion project commissioned in February 2025.
In June 2025, Rongke Power also commissioned Phase I of a major vanadium flow battery electrolyte production line project with a total investment of RMB 400 million. The project includes production lines for vanadium electrolyte and electrolyte crystal materials, with annual output equivalent to supporting approximately 1.5 GWh of vanadium flow battery capacity.
Other major operational projects across China include:
- Hunan Yinfeng New Energy operating a 66,000 m³/year vanadium electrolyte production base in Yichun, Jiangxi.
- Sichuan Development Xingxin Vanadium Energy Technology commissioning a 60,000 m³/year short-process vanadium electrolyte project in March 2025.
- Dali Energy Storage commissioning its 60,000 m³/year Zaoyang vanadium electrolyte production base in December 2025.
- Enerflow operating a 60,000 m³/year vanadium electrolyte production facility in Shandong.
- LB Group commissioning a 20,000 m³/year vanadium electrolyte project in March 2026.
- Wontai Power operating and expanding a 20,000 m³/year vanadium electrolyte production line in Gansu.
- HBIS Group operating existing vanadium electrolyte facilities alongside Phase I of its Chengde 50,000 m³/year electrolyte project.
- Pangang Group Vanadium Titanium operating a 2,000 m³/year demonstration vanadium electrolyte production line in Panzhihua.
Massive Pipeline of Planned and Under-Construction Capacity
Rongke Power continues to lead the next phase of industry expansion, with major projects under development in Nantong, Jilin, Henan, and Zhoukou, including the large-scale 450,000 m³/year Jilin vanadium electrolyte project. According to media reports, Rongke Power has already established the world’s largest vanadium battery energy storage materials and equipment manufacturing base, accounting for more than 60% of global installed and under-construction vanadium battery capacity, while vanadium electrolyte materials reportedly represent nearly 80% of the global market share.
Meanwhile, Hunan Yinfeng New Energy is rapidly expanding capacity through the 132,000 m³/year Jiangxi Yinhui expansion project and the large integrated Baotou vanadium flow battery industrial park project.
Other companies aggressively expanding planned or under-construction vanadium electrolyte capacity include Jianlong Group, Pangang Group Vanadium Titanium, Wontai Power, Sichuan Development Xingxin Vanadium Energy Technology, Shanghai Electric Energy Storage, Dali Energy Storage, Enerflow, LB Group, and Xingchen New Energy. Many of these companies are leveraging upstream vanadium and mineral resources to expand downstream into vanadium electrolyte production, VFB manufacturing, and integrated long-duration energy storage systems.

Strong Momentum for Long-Duration Energy Storage
The rapid expansion of vanadium electrolyte manufacturing reflects growing confidence in the long-duration energy storage market and the accelerating deployment of vanadium redox flow battery systems across China.
Large-scale investments are now extending across the entire industrial chain — from vanadium mining and refining to electrolyte production, battery stack manufacturing, and grid-scale energy storage deployment. Many projects are closely integrated with renewable energy developments, including large-scale wind and solar power projects, highlighting the increasingly strategic role of vanadium flow batteries in supporting China’s energy transition and grid modernisation efforts.
Industry analysts expect continued expansion of electrolyte production capacity to strengthen supply chain security, reduce production costs, and further accelerate the global commercial adoption of vanadium flow batteries for utility-scale and long-duration energy storage applications.
