ZhiQing Material Raises Seed Funding for AEM Technology

ZhiQing Material, a Chinese innovator in anion exchange membranes (AEMs), has successfully closed an angel funding round, securing 10 million yuan (approximately $1.4 million USD). The investment was spearheaded by prominent redox flow battery manufacturer Dalian Rongke Power, with participation from existing investor Roton Capital. This capital infusion is earmarked for advancing core material development and refining manufacturing processes.

Established in June 2023, ZhiQing Material focuses on the development and mass production of AEMs crucial for both hydrogen production via water electrolysis and for next-generation redox flow batteries. The company's founder, Peng Hanqing, brings nearly a decade of specialized research in AEMs from his tenure at Wuhan University. ZhiQing Material has cultivated an integrated technological framework, encompassing everything from resin synthesis to the final membrane product. This allows for stable, large-scale production, reportedly achieving tens of kilograms per batch with a single resin reaction unit, and enabling the supply of large-area membranes for electrolysis and battery applications.

The strategic advantage of AEMs lies in their ability to selectively permit anion passage. In water electrolysis, this enables operation in a mildly alkaline environment, significantly reducing reliance on expensive precious metal catalysts and thereby lowering overall system costs. These membranes can achieve current densities and response times comparable to proton exchange membrane (PEM) electrolyzers. For redox flow batteries, AEMs are vital for effectively suppressing the crossover of active materials, directly contributing to enhanced battery lifespan and capacity retention – critical factors for grid-scale energy storage solutions.

ZhiQing Material claims its proprietary synthesis process has yielded substantial improvements in key performance indicators. The membranes exhibit tensile strength exceeding 50 MPa with minimal swelling, below 8%. In water electrolysis tests, the company reports achieving a current density of 1 A/cm² and a pressure differential of 0.6 MPa, with hydrogen concentration in oxygen remaining below 0.5% and cell voltage reduced to 1.7V. Crucially, through strategic supply chain integration, ZhiQing Material asserts its pricing is approximately one-third that of comparable international products, offering a significant cost-competitiveness edge.

Since commencing product sales in March 2025, ZhiQing Material has already completed over 60 deliveries to more than 20 domestic and international clients, marking steady progress into industrial validation. The company has successfully passed certifications from multiple AEM electrolyzer manufacturers. In the redox flow battery sector, adoption by domestic firms is underway, with ongoing discussions for testing collaborations with European and South Korean companies. ZhiQing Material views market penetration for AEMs as a 5-10 year endeavor, emphasizing a strategy of sustained competitive development.

The company's leadership stresses that superior membrane performance alone is insufficient; a comprehensive, integrated solution is paramount. Over the next 12-18 months, ZhiQing Material plans to collaborate with supply chain partners to refine its complete solution offerings. This latest funding will support ongoing product development and enhancements, further improving AEM performance and reducing costs. The company also intends to explore AEM applications in carbon dioxide electrolysis, seawater desalination, and electrodialysis, while concurrently expanding its production facilities to scale capacity.

The global water electrolysis market is projected to reach $550 million by 2025 and expand to $3.77 billion by 2035, according to Global Growth Insights. Similarly, the market for redox flow batteries, a key technology for long-duration energy storage, is also experiencing significant growth, with some estimates suggesting a potential global market size of $30 billion by 2030. Against this backdrop of expanding markets, ZhiQing Material aims to establish a leading position by leveraging domestic manufacturing capabilities and its compelling cost advantage.
