Optimization of nickel hydroxide electrode of the hybrid supercapacitor

Obtaining of Ni–Al layered double hydroxide by slit diaphragm electrolyzer

“…and PTFE (3 % wt.) [21] on the current collector. The current collector has been prepared by welding a Ni mesh onto a Ni plate.…”

“…and PTFE (3 % wt.) [21] onto a special current collector (Ni mesh welded onto Ni foil). Electrolyte -6М KОН.…”

The properties investigation of the faradaic supercapacitor electrode formed on foamed nickel substrate with polyvinyl alcohol using

“…The active material should exhibit sufficiently high electrochemical activity and high specific surface area [25,26]. The active material need also to form a good contact with the electrode surface, so it wouldn't peel off at high charge-discharge rates [18]. This is because at the high charge-discharge rate the undesirable processes, such as gas evolution due to electrolyte decomposition, are more pronounced at high charge-discharge rates [27].…”

“…Знайдено оптимальний час осадження -10 і 20 хвилин. Показано, що ємкість при такому способі нанесення склада-ється з двох компонентів -ємкості композит-ного ПВС-Ni(OH) 2 [18]. Fulfilling this requirement enables the creation of rechargeable power sources with high durability [19,20].…”

The electrochemical cathodic template synthesis of nickel hydroxide thin films for electrochromic devices: role of temperature

“…Nickel hydroxide is the main component of nickel oxide electrode (NOE), which is used in alkaline accumulators [1,2] and hybrid supercapacitors [3,4]. Ni(OH) 2 also finds its applications in other fields: oxidation of organic compounds [5], sensors for some compounds [6], and electrochromic films [7].…”
