Isingeniso kanye Nokwelashwa Kwangaphambili Kwe-Nickel Foam

Igwebu le-nickeliyinto enhle kakhulu emunca umsindo ene-coefficient ephezulu yokumunca kumaza aphezulu; ukusebenza kwayo okumunca umsindo kumaza aphansi kungathuthukiswa ngokuklanywa kwesakhiwo esimunca umsindo. I-nickel foam nayo ingenye yezinto ezihamba phambili ze-electrodeamabhethri e-cadmium-nickel namabhethri e-hydrogen-nickel. I-nickel foam ngokwayo inezici eziningi ezinhle kakhulu. Akuwona nje kuphela amandla ayo adonsela phansi athile aphansi kakhulu, kodwa futhi indawo yawo engaphezulu incane kakhulu; Ubuningi bawo buwukukhanya kwe-ultra-light, okunezinhlobonhlobo eziningi kakhulu zezinkambu zohlelo lokusebenza kanye namathemba okusebenza. Ngaphambi kokusetshenziswa, kufanele kulashwe kusengaphambili. Kuphela ngokuphatha kusengaphambili insimbi ingathuthukisa ngempumelelo amandla ayo okusebenza kahle.

Ukwelashwa kwangaphambili kwegwebu le-nickel: Igwebu le-nickel lisikwa libe ngusayizi ofisa wesampula bese lifakwa kusixazululo se-HCl esingu-3.0 mol/L imizuzu engu-20 ukuze kukhishwe ungqimba lwe-oxide ebusweni balo. Kamuva, i-igwebu le-nickelisusiwe, ihlanjululwe ngokuphindaphindiwe nge-ethanol engena-hydrous namanzi e-ultrapure, yomiswa ngokwemvelo, bese ifakwe ku-ethanol e-anhydrous futhi ibekwe eceleni. Lapho i-electrolyte ine-acidic, igwebu le-nickel akufanele lisetshenziswe njenge-substrate.
