Abstract

With the increasing demand for high-performance energy storage, Zinc-ion Hybrid Capacitors (ZHSCs) have emerged as a promising solution, combining the high power density of supercapacitors with the high energy density of batteries. This review summarizes the recent progress in ZHSCs, focusing on cathode materials (carbon-based and MXenes), electrolyte optimization (aqueous and hydrogel), and anode protection strategies against dendrite growth. While significant achievements have been made, challenges such as low cathode capacity and poor anode stability remain. Future research should focus on interface engineering and advanced electrolyte design to further enhance the electrochemical performance of ZHSCs.
