A team led by Professor Li Xianfeng and Professor Yuan Zhizhang from the Department of Energy Storage Technology (DNL 17) at the Dalian Institute of Chemical Physics (DICP), Chinese Academy of Sciences (CAS), has developed a 250 kWh zinc-bromine flow battery system, which has been successfully put into grid-connected operation at the Yulin CAS Institute of Clean Energy Innovation.<\/p>\n\n\n

Comprising electrolyte storage tanks, stacks, and power control modules, the system has a designed total discharge energy of 250 kWh and an actual discharge energy of 259.2 kWh, with an energy density exceeding 60 Wh\/L calculated based on the total volume of electrolytes on both sides. The system incorporates the team’s independently developed 50 kWh-class high-area-capacity stacks and novel high-stability electrolyte. In collaboration with Professor Zeng Peng and Project Researcher Cui Shijie from the Shenyang Institute of Automation, CAS, the team implemented an intelligent electronic control design that enables real-time assessment of battery operating conditions, achieving adaptive equalization and independent control of individual stacks. This breakthrough addresses the technical challenge of poor voltage consistency in multi-stack series configurations and significantly enhances system reliability.<\/p>\n\n\n

The Department of Energy Storage Technology at DICP adheres to a balanced approach of fundamental and applied research. By constructing multi-scale mass transfer-reaction coupling pathways and regulating thermal and mass transfer processes at the membrane-electrode interface, the team achieved synergistic optimization of interfacial flow field and electric field distribution, promoting uniform zinc deposition and increased areal capacity. They also established a molecular engineering regulation theory of solvation structure, which mitigates the corrosion of battery materials by cathodic bromine and reduces self-discharge, thereby improving both the cycling stability and energy density of the battery. Combined with innovative stack structural design, these advances enabled the development of the 50 kWh-class zinc-bromine flow battery stack.<\/p>\n\n\n\n

The successful development of the 250 kWh zinc-bromine flow battery system lays a solid foundation for the integration and commercialization of megawatt-scale and larger zinc-bromine flow battery systems, and will help advance the progress of user-side flow battery energy storage technologies.<\/p>\n","protected":false},"excerpt":{"rendered":"
