Zinc-organic batteries (ZOBs) are gaining attention as sustainable and safe energy storage systems due to their low cost and environmental friendliness. Non-metallic charge carriers, such as H⁺ and NH₄⁺, offer advantages over Zn²⁺ due to their smaller size, lighter weight, and faster reaction kinetics, enabling better electrochemical performance. This review discusses various non-metallic cationic and anionic charge carriers in ZOBs, their physicochemical properties, and their impact on electrochemical metrics like capacity, rate capability, and cycle life. It highlights the potential of non-metallic ions in improving ZOB performance and outlines challenges and future directions for non-metal-ion-based ZOBs. The review also covers recent advances in non-metallic ion storage, including H⁺, NH₄⁺, Cl⁻, OH⁻, CF₃SO₃⁻, and SO₄²⁻, and their roles in organic cathodes. It discusses the structural design of organic cathode materials, ion-organic interactions, and redox charge storage mechanisms. The review emphasizes the importance of rational design and optimization of non-metallic ion storage for high-performance ZOBs, with a focus on improving capacity, voltage, and stability. The study also explores the potential of non-metallic anion/cation co-storage in ZOBs, which can enhance electrochemical metrics through synergistic interactions. Overall, the review provides insights into the development of next-generation ZOBs with improved energy storage capabilities.Zinc-organic batteries (ZOBs) are gaining attention as sustainable and safe energy storage systems due to their low cost and environmental friendliness.
