Indima ye-nickel mesh kwiibhetri ze-nickel-metal hydride
Ibhetri ye-nickel-metal hydrideyibhetri yesibini egcwalisekayo. Umgaqo wayo osebenzayo kukugcina kunye nokukhulula amandla ombane ngokusabela kweekhemikhali phakathi kwe-nickel yensimbi (Ni) kunye ne-hydrogen (H). I-nickel mesh kwiibhetri ze-NiMH idlala indima ebalulekileyo.
I-nickel mesh isetyenziswa kakhulunjengesixhobo se-electrode kwiibhetri ze-nickel-metal hydride, kwaye iqhagamshelana ne-electrolyte ukwenza indawo ye-electrochemical reactions. Ine-conductivity egqwesileyo yombane kwaye inokuguqula ngokufanelekileyo i-electrochemical reaction ngaphakathi kwebhetri ibe yi-flow yangoku, ngaloo ndlela iqonda imveliso yamandla ombane.
Umnatha wocingo lwe-nickel nawo unozinzo olulungileyo lwesakhiwo. Ngexesha lokutshaja kunye nenkqubo yokukhupha ibhetri, i-nickel wire mesh inokugcina imilo ethile kunye nokuzinza kwe-dimensional kwaye ithintele imiba yokhuseleko efana nesiphaluka esifutshane sangaphakathi kunye nokuqhuma kwebhetri. Kwangaxeshanye, ubume bayo obunoburharha bunceda i-electrolyte ukuba isasazeke kwaye ingene, iphucule ukusebenza kakuhle kwebhetri.
Ukwengeza, i-nickel wire mesh ikwanayo nefuthe elithile le-catalytic. Ngexesha lokutshaja kunye nokukhupha ibhetri, izinto ezisebenzayo kumphezulu we-nickel mesh zinokukhuthaza ukusabela kwe-electrochemical kunye nokuphucula ukutshaja kunye nokukhupha ukusebenza kakuhle kunye nobomi benkonzo yebhetri.
I-porosity kunye nomgangatho ophezulu wendawo ethile ye-nickel mesh ibonelela ngokusebenza okugqwesileyo njengemathiriyeli ye-electrode. Oku kuvumela iisayithi ezisebenzayo ngakumbi ngaphakathi kwebhetri, ukwandisa ubuninzi bamandla kunye nokuxinana kwamandla ebhetri. Ngelo xesha, esi sakhiwo sikwanceda ukungena kwe-electrolyte kunye nokusabalalisa kwegesi, ukugcina ukusebenza okuzinzileyo kwebhetri.
Ukushwankathela, i-nickel mesh kwiibhetri ze-nickel-metal hydride idlala indima ebalulekileyo. Njengempahla ye-electrode, ine-conductivity egqwesileyo, ukuzinza kwesakhiwo kunye nefuthe le-catalytic, elikhuthaza inkqubo yokusabela kwe-electrochemical ngaphakathi kwebhetri. Ezi mpawu zenza iibhetri ze-nickel-metal hydride zinezinga eliphezulu lokuxinana kwamandla, ubuninzi bamandla kunye nobomi obude, kwaye zisetyenziswa ngokubanzi kwizixhobo zombane eziphathwayo, izithuthi zombane, iinkqubo zokugcina amandla kunye nezinye iinkalo. Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, imimandla yokusebenza kunye nokusetyenziswa kweebhetri ze-nickel-metal hydride ziya kwandiswa ngakumbi kwaye ziphuculwe.
