Incazelo emfushane:

I-foam yethusi iwuhlobo olusha lwezinto ezisebenzayo ezinenani elikhulu lama-pores axhunyiwe noma angaxhumekile asakazwa ngokulinganayo ku-matrix yethusi. I-foam yethusi ine-conductivity enhle kanye ne-ductility. Uma iqhathaniswa negwebu le-nickel, inezindleko eziphansi zokulungiselela kanye nokuhamba kahle, futhi ingasetshenziswa ukulungisa izinto zebhethri ezingenayo i-electrode (inkampani yenethiwekhi), isithwali se-catalyst kanye nezinto ezivikela i-electromagnetic.
Ikakhulukazi, ithusi elinegwebu linezinzuzo ezithile ezisobala njenge-substrate yama-electrode ebhethri, kodwa ngenxa yokuthi ithusi alikwazi ukumelana nokugqwala njenge-nickel, liphinde likhawulele ezinye zezinhlelo zalo zokusebenza.

I-foam yethusi iwuhlobo olusha lwezinto ezisebenzayo ezinenani elikhulu lama-pores axhunyiwe noma angaxhumekile asakazwa ngokulinganayo ku-matrix yethusi. I-foam yethusi ine-conductivity enhle kanye ne-ductility. Uma iqhathaniswa negwebu le-nickel, inezindleko eziphansi zokulungiselela kanye nokuhamba kahle, futhi ingasetshenziswa ukulungisa izinto zebhethri ezingenayo i-electrode (inkampani yenethiwekhi), isithwali se-catalyst kanye nezinto ezivikela i-electromagnetic.
Ikakhulukazi, ithusi elinegwebu linezinzuzo ezithile ezisobala njenge-substrate yama-electrode ebhethri, kodwa ngenxa yokuthi ithusi alikwazi ukumelana nokugqwala njenge-nickel, liphinde likhawulele ezinye zezinhlelo zalo zokusebenza.
I-copper enegwebu ilungiswa nge-powder metallurgy kanye ne-electroplating, futhi insimbi enegwebu ilungiswa ngokungeza i-ejenti enegwebu ensimbi encibilikisiwe;
1.Amagwebu ensimbi ye-powder enziwe ngokungeza i-ejenti evuthelayo (efana ne-NH4Cl) kumpushana, i-ejenti efuthayo iyashintshashintsha ngesikhathi sokucwilisa, ishiye i-voids.
2. Indlela ye-electrochemical deposition ingasetshenziswa ukulungisa insimbi enegwebu ngesimo esivamile kanye ne-porosity efika ku-95%, kuhlanganise namagwebu ensimbi ane-Cu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe nezinye izinsimbi nama-alloys njengamathambo.

Insimbi ifakwa emzimbeni onezimbotshana ngendlela ye-electrochemical, futhi izingxenye ezifakiwe zihlanganiswa ndawonye ngokufaka i-sintering, futhi amandla afinyelela kugwebu lwensimbi olune-porosity edingekayo, ene-porosity ephezulu futhi engagcwaliswa ngezinto eziningi, njengama-catalysts. . i-electrolyte, njll.
3. Ngemboboigwebu lethusiilungiswa ngenqubo ye-sintering-desolvation, futhi i-electrolytic yethusi powder, izinhlayiya ze-NaCl nezithasiselo zixutshwe ngokufanayo futhi zicindezelwe zibe ama-compact aluhlaza. Isithando somlilo esivuthayo sibekwe endaweni ye-argon ukuze i-sintering, futhi umkhiqizo otholiwe ufakwa emanzini ashisayo ajikelezayo. Incibilikisiwe kudivayisi, bese igezwa ngamanzi okugeza e-ultrasonic kanye ne-acetone, futhi ekugcineni yomile ukuze yenze ama-pores avulekile, akhiwe inethiwekhi yesikhala exhunywe ngezindlela ezintathu, ene-porosity engu-50-81%, ububanzi be-pore obuyisilinganiso esingu-0.2- 4 mm, kanye nokusatshalaliswa kwezimbotshana.

      Igwebu Lethusi

      Incazelo Yomkhiqizo I-Copper Foam isetshenziswe kabanzi njengokulungiswa kwezinto ezithwala ibhethri ezingezinhle, i-electrode substrate yebhethri ye-lithium ion noma uphethiloli, isithwali se-cellcatalyst nezinto zokuvikela i-electromagnetic. Ikakhulukazi i-foam yethusi iyisisekelo esisetshenziswa njenge-electrode yebhethri, enezinzuzo ezithile ezisobala. Isici soMkhiqizo 1) igwebu lethusi linezakhiwo ezinhle kakhulu ezishisayo, zingasetshenziswa kabanzi ezingxenyeni zemoto/zikagesi neze-elekthronikhi zerediyo yokuqhuba ukushisa...
