Shenzhen ZH Energy Storage Technology Co., Ltd. is a global provider of materials and equipment for flow batteries, founded in 2021. The company specializes in the development, manufacturing, and application of long-duration flow battery energy storage systems. Its mission addresses the high initial cost of flow battery technology by focusing on producing low-cost, high-performance materials. This approach allows for the creation of safer, large-scale energy storage solutions, supporting carbon neutrality goals.
Shenzhen ZH Energy Storage Technology Co., Ltd. offers a suite of products, including non-fluorinated ion-exchange membranes, single cells, and standardized stacks with power ratings from 1kW to 32kW. The company also provides flow battery test systems and advanced Battery Management Systems (BMS). With operations in Shenzhen, Changsha, and Shanxi, the company maintains manufacturing capabilities with an annual stack production capacity in the hundreds of megawatts, backed by ISO9001 quality management certification.
Battery Technology
Shenzhen ZH Energy Storage Technology Co., Ltd. focuses on both Vanadium Redox Flow Batteries (VRFBs) and emerging iron-sulfur flow battery systems. VRFBs are known for their long lifespan, scalability, safety, and suitability for grid-level applications. The iron-sulfur flow batteries provide advantages in cost and performance due to abundant raw materials and safer operation. The company designs standardized modules of 250kW and 500kW for hundred-megawatt flow battery systems.
ZH Energy manufactures core components such as battery stacks, single cells, and modular systems, ranging from 3W to 500kW. Its material innovations include high-efficiency catalyst electrodes, novel iron-sulfur electrolytes, and non-fluorinated ion-exchange membranes. The company leverages nearly two decades of industry experience through its founder, Dr. Wei Xie, and collaborates with Central South University to develop advanced materials. This work contributes to reducing costs and improving the performance and safety of flow battery installations, fostering wider market adoption.
Recent Projects
In 2025, Shenzhen ZH Energy Storage Technology Co., Ltd. unveiled its Sulfur-Iron Flow Battery System (125kW/1MWh) at the Beijing International Summit and Exhibition on Energy Storage (ESIE 2025). This system features zero combustion or explosion risk, ultra-low life cycle energy cost (approximately 0.1 yuan/kWh), and a reduced electrolyte cost (around 0.2 yuan/Wh). The technology uses abundant raw materials, ensuring a stable supply chain. The company continues to advance the mass production of standardized battery stacks and modular storage units to support grid-scale deployments. The company actively monitors developments in the energy industry, such as new legislation in the UK concerning PV and energy storage for new homes starting in 2025.
Investors
Shenzhen ZH Energy Storage Technology Co., Ltd. has attracted support from several notable investors. It received a seed investment of approximately 10 million yuan from Sequoia China Seed Fund (now HongShan China Seed Fund) in early 2022. This initial funding supported talent acquisition and pilot product testing. Additional equity investments have come from Hidden Hill Capital, which focuses on tech-driven industrial innovation, and CMB International, the investment arm of China Merchants Bank. These strategic investments have been crucial in enabling ZH Energy to expand its research and development efforts, scale production, and establish integrated system deployment bases.
