Triple Redox-Enabled High-Entropy Metal-Organic Coordination Driving High-Performance Aqueous Zinc-Ion Batteries.

ABSTRACT: High entropy (HE) nanomaterials offer a promising strategy for advancing aqueous zinc-ion batteries (AZIBs). In this study, 1,4-dihydroxyanthraquinone (1,4-DHAQ) is employed as an organic ligand to coordinate with multiple metal ions, forming a series of binary to quinary high-entropy (HE) nanomaterials. All synthesized materials exhibit a layered flower cluster structure. Among them, MnCoNiFeCu-1,4-DHAQ (denoted as HE-1,4-DHAQ) demonstrates the largest specific surface area and pore volume, along with superior electronic conductivity. HE-1,4-DHAQ delivers outstanding electrochemical performance, maintaining a high specific capacity of 222.6 mAh·g^-1 after 150 cycles at a current density of 0.3 A·g^-1. A combination of in situ powder X-ray diffraction, ultraviolet and v
