Rongke Power specializes in Vanadium Flow Batteries (VFBs) with water-based vanadium electrolytes, offering inherent safety, scalability, durability, and 100% capacity retention over 25 years. They also develop Iron-Vanadium Flow Batteries (Fe/V FFBs) in partnership with Saudi Aramco, using reduced vanadium, operating from -8°C to +60°C without active thermal management. The company holds over 450 patents in flow battery components and integration.
Vanadium Flow Battery systems: water-based electrolytes, long cycle life, recyclable, 100% capacity retention over 25 years; Iron-Vanadium Flow Battery systems: industrial-grade, less vanadium, extreme temperature tolerance (-8°C to +60°C), no active thermal management.
2025: GWh-scale grid-connected VFB station in Xinjiang, China; 2025: world’s first commercial Iron-Vanadium flow battery system for solar-assisted industrial backup in Saudi Arabia with Aramco; 2025: facility expansion in Dalian, China, to boost manufacturing capacity for electrolytes and bipolar plates; over 3 GWh of global deployments.
Rongke Power’s investors include Jinding Capital, Legend Capital, China Zhongji Investment, Desheng Group, Roton Capital, Eastern Bell Capital, JT Group, and Rongtuo Capital Management. In 2023, it completed a Series B round raising CNY 1B (approximately $150M), led by Eastern Bell Capital and JT Group.
