چکیده
Nickel foam is a shallow-density metal part with very high electrical and thermal conductivity. Nickel foam is used widely as the current collector in electrochemical energy storage. In previous research, the electrolytes used for electrodes in energy sources in the laboratory are often of the aqueous electrolyte type due to their low cost and easy access. In this study, studies were performed to identify and confirm the accuracy of nickel foam, such as scanning electron microscopy and X-ray energy diffraction spectroscopy. Then, in common electrolytes, ۱ M potassium hydroxide (KOH) and ۰.۱ M sodium sulfate (Na۲SO۴) were investigated by CV, GCD, and EIS analyses. Finally, according to the data and results, the desired electrolyte can be selected depending on the type of use in different environments.Nickel foam is a shallow-density metal part with very high electrical and thermal conductivity.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
