Mitigating Diffusion-Limited Concentration Polarization via Intrinsic Electrocapillary Effects in Engineered Hollow Cathodes

Jiaxian Zheng, Jiahao Li, Fangwang Ming, Yun‐Pei Zhu et autres

Aqueous zinc-ion batteries (AZIBs) are promising for grid-scale energy storage but suffer from sluggish ion diffusion kinetics, severe concentration polarization, and rapid performance decay. While structural engineering offers partial mitigation, a more fundamental solution lies in actively controlling interfacial mass transport. Herein, …
