“…For instance Co/Al layered double hydroxide displays interesting capacitive performance ( Table 6) as well as a long term cycling under large current density when supported on porous Ni electrode [135]. Same authors report the performance of NiAl-CO 3 LDH supported on porous Ni electrode in hexacyanoferrate(III) media [136].…”

From an exhaustive overview based on applicative academic literature and patent domain, the relevance of Layered Double Hydroxide (LDHs) as electrode materials for electrochemical detection of organic molecules having environmental or health impact and energy storage is evaluated. Specifically the focus is driven on their application as supercapacitor, alkaline or lithium battery and (bio)-sensor. Inherent to the high versatility of their chemical composition, charge density, anion exchange capability, LDH-based materials are extensively studied and their performances for such applications are reported. Indeed the analytical characteristics (sensitivity and detection limit) of LDH-based electrodes are scrutinized, and their specific capacity or capacitance as electrode battery or supercapacitor materials, are detailed.

“…Namely, an electrochemical activation of the electrode seems to be required, which is achieved through repeated cycling. 26 LDH with other supercapacitor materials are very difficult due to the different applied experimental conditions. The specific capacitance and coulombic efficiency of different supercapacitor materials prepared by chemical co-precipitation method are summarized in Table 2.…”

“…Unfortunately, cobalt-based electrode materials may show low specific surface area, poor electron/ion conductivity and severe attenuation in chargedischarge process. To address these challenges, dual and ternarymetal composite materials such as Co/Cu, 18 Co/Ni, 19,20 Co/Mn, 21,22 Co/Al, 23 Co/Zn/Ni 24 and Co/Al/Ni [25][26][27] have been introduced to ES electrode materials. However, few reports have been found for Co/Fe hydroxides using as electrode materials.…”

Co-Fe layered double hydroxides (Co 1−x Fe x LDHs) were synthesized by a chemical co-precipitation method. It was found that the molor ratio of Co to Fe had a significant effect on the electrochemical activity. The specific capacitance of 869 F g −1 was achieved when the molor ratio of Co to Fe was equal to 0.74:0.26. The Co 0.74 Fe 0.26 LDH sample had a BET specific surface area of 202.9 m 2 g −1 and total pore volume of 0.6 cm 3 g −1, which led to the high liquid-solid interfacial area and further increased the utilization of the active materials. Additionally, the Co 0.74 Fe 0.26 LDH electrode exhibited a good electrochemical stability with beyond 99.5% of the initial capacitance over 1000 consecutive cycles at 1 A g −1. It is a promising electrode material for supercapacitor.

“…Nickel is characterized by the low overpotential of hydrogen release in comparison to other metals [2,3,5]. Additionally, the activity of nickel electrodes may be enhanced through an increase in their specific surface area and activation of the electrode surface (additions, introducing tensions) [2][3][6][7][8][9][10].…”

The presented paper discusses a possibility of developing surface of nickel powder by cyclic oxidation (air) and reduction (H2) processes for their further use as electrode precursors, in electrochemical processes of hydrogen production. The studies of a samples surface were conducted with the use of SEM/EDX technique. The electrochemical properties of porous Ni electrodes were examined by potentiostatic method. The authors applied a rotating electrode during those tests. The current-potential relationship was obtained at 40ºC 1M KOH with Hg|HgO reference electrode, i.e. under conditions similar to the industrial process of hydrogen production.
