Taw qhia thiab Pretreatment ntawm Nickel Foam

Nickel ua npuas ncaujyog ib qho zoo heev suab-absorbing khoom nrog lub siab nqus coefficient ntawm high zaus; nws lub suab-absorbing kev ua tau zoo ntawm tsawg zaus tuaj yeem txhim kho los ntawm kev tsim cov suab-absorbing qauv. Nickel ua npuas ncauj kuj yog ib qho ntawm cov khoom siv electrode zoo tshaj plaws raucadmium-nickel roj teeb thiab hydrogen-nickel roj teeb. Nickel ua npuas ncauj nws tus kheej muaj ntau yam zoo heev. Tsis tsuas yog nws tus kheej lub ntiajteb txawj nqus tsawg heev, tab sis kuj nws qhov chaw tshwj xeeb yog me me; nws tus kheej huab hwm coj yog ultra-lub teeb, uas muaj ntau yam ntawm daim ntawv thov teb thiab daim ntawv thov kev cia siab. Ua ntej siv, nws yuav tsum tau kho ua ntej. Tsuas yog los ntawm kev kho cov hlau ua ntej nws tuaj yeem txhim kho nws tus kheej lub zog efficiency.

Nickel ua npuas ncauj pretreatment: Nickel ua npuas ncauj yog txiav mus rau qhov loj me ntawm cov qauv thiab impregnated nyob rau hauv ib tug 3.0 mol / L HCl tov rau 20 feeb kom tshem tawm cov oxide txheej ntawm nws nto. Tom qab ntawd, lubnickel ua npuas ncaujraug tshem tawm, yaug ntau zaus nrog anhydrous ethanol thiab dej ultrapure, qhuav lawm, thiab ces impregnated nyob rau hauv anhydrous ethanol thiab tso tseg. Thaum cov electrolyte yog acidic, nickel ua npuas ncauj yuav tsum tsis txhob siv los ua substrate.
