Zinc-ion capacitors and zinc-ion batteries, as novel energy storage devices, have garnered widespread attention due to their high safety, low cost, and environmental friendliness. In these devices, the solid electrolyte interphase (SEI) membrane plays a crucial role, significantly influencing the performance and lifespan of the devices. This review summarizes the formation mechanism, chemical composition, and functions of the SEI membrane in zinc-ion capacitors and batteries. The key factors influencing the formation of the SEI membrane, including electrolyte composition, electrode materials, and electrochemical conditions, are discussed and the impact of the SEI membrane on cycle stability, energy density, power density, lifespan, and safety is analyzed. In addition, this review summarizes the optimization strategies for the SEI membrane, such as material modification and electrolyte adjustment, as well as surface coating techniques and the use of additives. By introducing characterization techniques, the structure and properties of the SEI membrane are demonstrated to be analyzed effectively. Finally, this review discusses the challenges in current research and future research directions, emphasizing the importance of multiscale modeling and sustainable material development. This review aims to guide future research and application of zinc-ion storage devices.
