Full-industry-chain Vanadium Energy Storage
Wontai Power has constructed a closed-loop industrial chain covering vanadium ore mining, high-purity vanadium feedstock, vanadium electrolyte and energy storage system integration, ranking among China’s few long-duration energy storage enterprises with self-controlled upstream vanadium resources.
Backed by its self-owned medium-sized vanadium mine in Dunhuang to secure raw material supply and mitigate raw material price volatility, the company manufactures high-purity vanadium pentoxide at the Qingyang base and supports the Jiuquan electrolyte plant. With proprietary full-electrolysis technology, the enterprise develops wide-temperature high-performance vanadium electrolyte adaptable to diverse complex operating conditions. The integrated industrial chain delivers competitive edges in cost control, product quality and on-time delivery. The company supplies core materials and system solutions for independent energy storage and wind-solar paired storage projects across China and overseas to fuel the expansion of long-duration energy storage industry.
