Abstract
Ni(OH)2 nanosheet, acting as a potential active material for supercapacitors, commonly suffers from sluggish reaction kinetics and low intrinsic conductivity, which results in suboptimal energy density and long cycle life. Herein, a convenient electrochemical halogen functionalization strategy is applied for the preparation of mono/bihalogen engineered Ni(OH)2 electrode materials. The theoretical calculations and experimental results found that thanks to the extraordinarily high electronegativity, optimal reversibility, electronic conductivity, and reaction kinetics could be achieved through F functionalization . However, benefiting from the largest ionic radius, INi(OH)2 contributes the best specific capacity and morphology transformation, which is a new finding that distinguishes it from previous reports in the literature. The exploration of the interaction effect of halogens (F, INi(OH)2 , F, BrNi(OH)2 , and Cl, INi(OH)2 ) manifests that F, INi(OH)2 delivers a higher specific capacity of 200.6 mAh g-1 and an excellent rate capability of 58.2% due to the weaker electrostatic repulsion, abundant defect structure, and large layer spacing. Moreover, the F, INi(OH)2 //FeOOH@NrGO device achieves a high energy density of 97.4 Wh kg-1 and an extremely high power density of 32426.7 W kg-1 , as well as good cycling stability. This work develops a pioneering tactic for designing energy storage materials to meet various demands.

Abstract
As a promising supercapacitor electrode material, NiMn-LDH has attracted great attention due to its high theoretical capacity and easy preparation. However, the development and application of NiMn-LDH in supercapacitors are limited because of its poor cycling stability and low electrical conductivity. To solve these problems, a NiMnMg-LDH with a three-dimensional porous morphology has been successfully fabricated by doping with Mg to improve its electrochemical properties. Experimental results indicate that NiMnMg-LDH-7 delivers a specific capacitance of 1772 F g-1 at a current density of 1 A g-1. Moreover, it can still reach 1080 F g-1 when the current density is increased 10 times, suggesting excellent rate capability. The asymmetric supercapacitor (ASC) NiMnMg-LDH-7//AC can provide a high energy density of 28 W h kg-1 at a power density of 700 W kg-1. Furthermore, the energy density can still reach 16 W h kg-1 even if the power density is increased to close to 3500 W kg-1. The capacity retention of this ASC device can reach 74% after 3000 cycles at a current density of 3 A g-1. These excellent properties of NiMnMg-LDH can be attributed to the obvious improvement of its specific surface area and electrical conductivity owing to doping with the element magnesium. We believe that this work could provide a new idea for the preparation of high-performance electrode materials for supercapacitors.

Abstract
It is extremely crucial to design and match high-quality cathode and anode for achieving high-performance asymmetric supercapacitors (ASCs). Herein, Co3 (PO4 )2 @NiCo-LDH/Ni foam (CP@NCOH/NF) cathode with hierarchical morphology and graphene hydrogel/Fe-Ni phosphide/Ni foam (GH/FNP/NF) anode with the robust and porous structure are elaborately designed and prepared, respectively. Owing to their unique and profitable structures, both CP@NCOH/NF and GH/FNP/NF electrodes yield the superior capacity (10760 and 2236 mC cm-2 at 2 mA cm-2 , respectively), good rate capability (63% retention at 200 mA cm-2 and 52% retention at 50 mA cm-2 , respectively), and excellent cycling stability (72% and 74% retention after 10 000 cycles, respectively). Benefiting from their matchable electrochemical performances, the configured solid-state CP@NCOH/NF//GH/FNP/NF ASC outputs both competitive energy density (80.2 Wh kg-1 /4.1 mWh cm-3 ) and power density (14563 W kg-1 /750 mW cm-3 ), companied by remarkable cyclability (71% retention after 10 000 cycles), manifesting its great promise for large-scale integrated energy-storage system.
