Indima ye-nickel mesh kumabhethri e-nickel-metal hydride
Ibhethri le-nickel-metal hydrideiyibhethri lesibili elishajekayo. Umgomo wayo wokusebenza ukugcina nokukhulula amandla kagesi ngokusabela kwamakhemikhali phakathi kwe-metal nickel (Ni) ne-hydrogen (H). I-nickel mesh kumabhethri e-NiMH idlala izindima ezimbalwa ezibalulekile.
I-nickel mesh isetshenziswa kakhulunjengento ye-electrode kumabhethri e-nickel-metal hydride, futhi ithinta i-electrolyte ukuze yakhe indawo yokusabela kwe-electrochemical. Ine-conductivity kagesi enhle kakhulu futhi ingaguqula ngempumelelo ukusabela kwe-electrochemical ngaphakathi kwebhethri ibe ukugeleza kwamandla kagesi, ngaleyo ndlela ibone ukuphuma kwamandla kagesi.
I-nickel wire mesh nayo inokusimama okuhle kwesakhiwo. Phakathi nenqubo yokushaja nokukhipha ibhethri, i-nickel wire mesh ingagcina umumo othile nokuzinza kohlangothi futhi ivikele izinkinga zokuphepha ezifana ne-short circuit yangaphakathi kanye nokuqhuma kwebhethri. Ngesikhathi esifanayo, isakhiwo sayo esinezimbotshana sisiza i-electrolyte ukuthi isakaze ngokulinganayo futhi ingene, ithuthukise ukusebenza kahle kwebhethri.
Ngaphezu kwalokho, i-nickel wire mesh ibuye ibe nomthelela othile we-catalytic. Phakathi nenqubo yokushaja nokukhipha ibhethri, izinto ezisebenza ngamandla endaweni ye-nickel mesh zingakhuthaza ukusabela kwe-electrochemical futhi zithuthukise ukusebenza kahle kokushaja nokukhipha kanye nempilo yesevisi yebhethri.
I-porosity kanye nendawo ethile ephezulu ye-nickel mesh ibuye inikeze ukusebenza okuhle kakhulu njenge-electrode material. Lokhu kuvumela amasayithi asebenza kakhulu ngaphakathi kwebhethri, okwandisa ukuminyana kwamandla kanye nokuminyana kwamandla ebhethri. Ngesikhathi esifanayo, lesi sakhiwo sisiza nokungena kwe-electrolyte nokusabalalisa kwegesi, ukugcina ukusebenza okuzinzile kwebhethri.
Ngamafuphi, i-nickel mesh kumabhethri e-nickel-metal hydride idlala indima ebalulekile. Njengempahla ye-electrode, ine-conductivity enhle kakhulu, ukuzinza kwesakhiwo kanye nomphumela we-catalytic, okhuthaza inqubo yokusabela kwe-electrochemical ngaphakathi kwebhethri. Lezi zici zenza amabhethri e-nickel-metal hydride abe nokuminyana kwamandla aphezulu, ukuminyana kwamandla nokuphila isikhathi eside, futhi asetshenziswa kakhulu kumadivaysi e-elekthronikhi eselula, izimoto zikagesi, izinhlelo zokugcina amandla kanye neminye imikhakha. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ukusebenza kanye nezinkambu zokusebenzisa amabhethri e-nickel-metal hydride azonwetshwa futhi athuthukiswe.
