“…56 Carbon-ZS shows a small value crossing with the Z axis, which denotes that Carbon-ZS has lower interface contact resistance, because Carbon-ZS has a proper pore size favorable for electrolyte ion transport. In the low frequencies, the vertical curve means an ideal capacitive behavior and a fast diffusion of the electrolyte ions (K + and OH -) in the pores of electrode materials, 57 i.e. the larger the curve slope, the better capacitive behavior.…”

“…Electrochemical capacitors (ECs), also known as supercapacitors, 1,2 are a new type of energy storage device that have been developed in recent years. Typically, according to the charge storage mechanism of different electrode materials, [3][4][5] the use of supercapacitors can be divided into two categories including the electric double layer capacitor (EDLC), Faraday pseudocapacitor and hybrid supercapacitor. [6][7][8][9] The electric double layer capacitor uses high surface area carbon as the electrode material, while the Faraday pseudocapacitor uses a transition metal oxide or a conductive polymer as an electrode material.…”

Layered double hydroxides (LDH) as active electrode materials have become the focus of research in energy storage applications. The manufacturing of excellent electrochemical performance of the LDH electrode is still a challenge. In this paper, the production of CoAl-LDH@Ni(OH) 2 is carried out in two steps, including hydrothermal and electrodeposition techniques. The prominent features of this electrode material are shown in the structural and morphological aspects, and the electrochemical properties are investigated by improving the conductivity and cycle stability. The core of this experimental study is to investigate the properties of the materials by depositing different amounts of nickel hydroxide and changing the loading of the active materials. The experimental results show that the specific capacity is 1810.5F · g −1 at 2 A/g current density and the cycle stability remained at 76% at 30 A g −1 for 3000 cycles. Moreover, a solid-state asymmetric supercapacitor with CoAl-LDH@Ni(OH) 2 as the positive electrode and multi-walled carbon nanotube coated on the nickel foam as the negative electrode delivers high energy density (16.72 Wh kg −1 at the power density of 350.01 W kg −1 ). This study indicates the advantages of the design and synthesis of layered double hydroxides, a composite with excellent electrochemical properties that has potential applications in energy storage. Supercapacitors (SCs) are currently of widespread interest in energy storage, which has become a research area due to the development of various energy storage devices, long cycle life, high power density, high safety, and low maintenance costs. Numerous studies have concentrated on the enhancing the performance of the electrode material. Electrochemical capacitors (ECs), also known as supercapacitors, 1,2 are a new type of energy storage device that have been developed in recent years. Typically, according to the charge storage mechanism of different electrode materials, 3-5 the use of supercapacitors can be divided into two categories including the electric double layer capacitor (EDLC), Faraday pseudocapacitor and hybrid supercapacitor.6-9 The electric double layer capacitor uses high surface area carbon as the electrode material, while the Faraday pseudocapacitor uses a transition metal oxide or a conductive polymer as an electrode material.The electric double layer capacitor is a new capacitor which is based on the interface of the double layer theory.10,11 The reversible electrostatic adsorption /desorption on the electrode surface is used to store the charge.12 By arrangement of the opposite sign charge an electric double layer is formed in the vicinity of the electrode/electrolyte interface, a so-called "electric double layer capacitor".13,14 Its working principle is: the electrode surface and solution on both sides of the electrolyte solution appear on the opposite sides of the excess charge.Hydrotalcite-like layered clays, also well-known LDH, 15-18 have been extensively explored in the field of catalysts and catalyst supports...
