The development of traditional battery electrode structures has long relied on trial-and-error optimization of individual parameters, such as ionic conductivity, electronic conductivity, and active reaction area, making it difficult to achieve breakthroughs in overall performance[1].This work addresses the persistent challenge of rational electrode design by introducing a topology optimization framework for porous electrodes, founded on reaction engineering principles[1,2]. The central aim of this study is to enhance power density by simultaneously maximizing mass transport and reaction rates throughout the porous electrode. As shown in Fig. 1, the results demonstrate energy storage efficiency comparable to conventional energybased method, while enabling more uniform electrolyte flow through streamlined material arrangements—offering a scalable pathway for high-performance electrode design.
