Layered double hydroxides (LDHs) are one class of two-dimensional materials, with tunable chemical composition and large interlayer spacing, that is a potential cathode material candidate for aqueous zinc-ion batteries (AZIBs). Nevertheless, the low conductivity fragile structure LDH have impeded their practical application in AZIBs. Herein, ternary CoMnAl synthesized via facile coprecipitation method as AZIB. The interaction between trivalent Al3+ Mn3+ not only lowers redox energy barrier but also enhances electronic structure, proved by EIS analysis DFT simulation. As result, displays high specific capacity 238.9 mAh g−1 at 0.5 A g−1, an outstanding rate performance (138.8 5 g−1), stable cyclability (92% retention after 2000 cycles).

Abstract To enhance the electrochemical performance of NiMn‐LDHs electrode materials, this study explores metal Co doping and synthesizes nano‐onion‐like NiCoMn‐LDHs composites. By examining effects various heat treatment temperatures (100°C, 110°C, 120°C, 130°C, 140°C), we identified that prepared at 130°C exhibited superior performance. The results reveal significantly increases specific capacitance compared with undoped NiMn‐LDHs. achieved a 4413 F g 1 A −1 maintained 3055 10 , demonstrating excellent rate These findings highlight benefits optimized for improving in supercapacitor applications, providing strong foundation their use high‐performance energy storage devices.
