A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies

ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in real time, offering feedback‐driven control over key processes. In this mini review, we systematically categorize intelligent fluids into four principal types: shear‐responsive, electromagnetic field‐responsive, thermally adaptive, and stimulus‐free. We discuss their unique rheological behaviors and functional contributions to the dynamic regulation of ion transport, interfacial self‐healing, and mechanical reinforcement. Particular attention is given to their implementation across electrolytes, electrodes, and interfaces, with an emphasis on their roles in suppressing dendrite growth, stabilizing interfaces, and improving thermal resilience. Finally, we highlight the emerging directions in this field, including philosophical thinking of design, the development of hybrid multistimuli‐responsive fluids, advanced in situ rheological characterization tools, interdisciplinary strategies for integration and practical applications of these fluids. Together, these advances provide a path toward the realization of next‐generation batteries that are intelligent, robust, and adaptable to complex operational demands.
