Interactions Between Trivalent Elements Enable Ultrastable LDH Cathode for High-Performance Zinc Battery
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 and fragile structure of LDH have imp...

| description | 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 and fragile structure of LDH have impeded their practical application in AZIBs. Herein, a ternary CoMnAl LDH is synthesized via the facile coprecipitation method as the cathode material for AZIB. The interaction between trivalent Al<sup>3+</sup> and Mn<sup>3+</sup> not only lowers the redox energy barrier but also enhances the electronic structure, as proved by EIS analysis and DFT simulation. As a result, the synthesized CoMnAl LDH displays a high specific capacity of 238.9 mAh g<sup>−1</sup> at 0.5 A g<sup>−1</sup>, an outstanding rate performance (138.8 mAh g<sup>−1</sup> at 5 A g<sup>−1</sup>), and a stable cyclability (92% capacity retention after 2000 cycles). |
