Xa uthetha ngeebhetri ezinokutshajwa, ibhetri yeNiCad kunye neIbhetri yeNiMHZimbini iindidi zebhetri ethandwa kakhulu kwindawo yabathengi kunye neshishini.Ibhetri yeNiCad yenye yeyona ndlela ilungileyo yebhetri egcwalisekayo.Kamva, ibhetri ye-NiMH ithathe indawo yebhetri ye-NiCad kwiindawo zabathengi kunye nezoshishino ngenxa yeenzuzo zayo.Namhlanje, ibhetri ye-NiMH ithandwa kakhulu kunebhetri yeNiCad kwezinye iindawo.
Intshayelelo esisiseko yeebhetri zeNiCad
Iibhetri zeNiCad (Nickel Cadmium) yenye yezona bhetri zindala ezinokutshajwa, bezikho ukususela ekupheleni kwenkulungwane ye-19.Zenziwe nge-nickel oxide hydroxide kunye ne-cadmium kwaye zisebenzisa i-alkaline electrolyte.Iibhetri zeNiCad ziqhele ukusetyenziswa kwizixhobo zombhobho osezantsi njengeefowuni ezingenazintambo, izixhobo zombane, kunye nezinto zokudlala zombane.
Enye yeenzuzo eziphambili zeebhetri zeNiCad kukuba azibizi kakhulu xa kuthelekiswa nezinye iintlobo zeebhetri.Ukongeza, banoxinzelelo olukhulu lwamandla, okuthetha ukuba banokugcina amandla amaninzi kwindawo encinci.Iibhetri zeNiCad nazo zinokugcinwa kakuhle kwentlawulo, oku kuthetha ukuba zinokubamba intlawulo ixesha elide nokuba zingasetyenziswa.
Ngelishwa, iibhetri zeNiCad zineengxaki ezinkulu.Enye yezona zinto zibalulekileyo kukuba bakhathazwa "yimpembelelo yememori", okuthetha ukuba ukuba ibhetri ikhutshwe ngokuyinxenye kwaye iphinde itshajwe, iya kubamba intlawulo engaphelelanga kwixesha elizayo kwaye ilahlekelwe ngumthamo ekuhambeni kwexesha.Umphumo wememori unokuncitshiswa ngolawulo olululo lwebhetri.Nangona kunjalo, kuseyingxaki kubasebenzisi abaninzi.Ukongeza, iibhetri zeNiCad ziyityhefu kwaye kufuneka zihlaziywe okanye zilahlwe ngokufanelekileyo.
Intshayelelo esisiseko yeebhetri zeNiMH
Iibhetri zeNiMH (Nickel Metal Hydride) zaphuhliswa ekupheleni kweminyaka yee-1980 kwaye zakhawuleza zaduma ngenxa yokusebenza kwazo okuphuculweyo kwiibhetri zeNiCad.Zenziwe nge-nickel kunye ne-hydrogen kwaye zisebenzisa i-alkaline electrolyte, efana neebhetri zeNiCad.Iibhetri ze-NiMH zihlala zisetyenziswa kwizixhobo eziphezulu zokukhupha amanzi ezifana neekhamera zedijithali, iikhamera, kunye nezixhobo zomdlalo eziphathekayo.
Enye yeenzuzo eziphambili zeebhetri ze-NiMH kukuba azikhathazwa ziziphumo zememori, oku kuthetha ukuba zinokuphinda zitshajwe nokuba zikhutshiwe kangakanani na.Oku kubenza balungele izixhobo ezifuna ukutshaja rhoqo, njengeekhamera zedijithali okanye iilaptops.Iibhetri ze-NiMH zinetyhefu encinci kuneebhetri zeNiCad kwaye zinokulahlwa ngokukhuselekileyo ngaphandle kokwenza umonakalo kokusingqongileyo.
Ngaphandle kwezi zibonelelo, iibhetri ze-NiMH zinezithintelo ezithile.Enye yezona zinto zibalulekileyo kukuba zibiza kakhulu kuneebhetri zeNiCad.Ukongeza, banoxinano lwamandla asezantsi, okuthetha ukuba bafuna indawo engaphezulu yokugcina umlinganiselo ofanayo wamandla.Ekugqibeleni, iibhetri ze-NiMH zinobomi obufutshane beshelufu kuneebhetri zeNiCad, oku kuthetha ukuba zilahlekelwa yintlawulo yazo ngokukhawuleza xa zingasetyenziswa.
Umahluko phakathi kwebhetri yeNiCad kunye nebhetri yeNiMH
Umahluko phakathi kwebhetri yeNiCad kunye nebhetri ye-NiMH inokudida abantu abaninzi, ngakumbi xa ukhetha okulungileyo kwiimfuno zabo.Zombini ezi ntlobo zeebhetri zineengenelo kunye nezingeloncedo zazo, ngoko ke kubalulekile ukuqonda ukuba zithini ukwenza isigqibo esinolwazi malunga nokuba yeyiphi ekufanelekela iimfuno zakho, nokuba kubathengi okanye kwindawo yoshishino.Kweli nqaku, siza kuxubusha umahluko phakathi kweebhetri ze-NiCad kunye ne-NiMH, kunye ne-pros and cons zabo.Nangona zibonakala zifana, zisenomohluko owahlukileyo kwisikhundla, impembelelo yenkumbulo, kunye nabanye.
1.Umthamo
Umahluko omkhulu phakathi kweebhetri zeNiMH kunye neNiCad ngumthamo wazo.Ibhetri yeNiMH inomthamo ophezulu kunebhetri yeNiCad.Ukusebenzisa ibhetri ye-NiCad kwindawo yoshishino ayikhuthazwa kumthamo wayo ophantsi.Ngokuqhelekileyo, umthamo webhetri ye-NiMH ngamaxesha angama-2-3 aphezulu kunebhetri yeNiCad.Iibhetri ze-NiCad zidla ngokuba nomthamo we-1000 mAh (iiyure ze-milliamp), ngelixa iibhetri ze-NiMH zinokufikelela kwi-3000 mAh yomthamo.Oku kuthetha ukuba iibhetri zeNiMH zinokugcina amandla amaninzi kwaye zihlala ixesha elide kuneebhetri zeNiCad.
2.IKhemistri
Omnye umehluko phakathi kweebhetri zeNiCad kunye ne-NiMH yikhemistri yazo.Iibhetri zeNiCad zisebenzisa i-nickel-cadmium chemistry, ngelixa iibhetri ze-NiMH zisebenzisa i-nickel-metal hydride chemistry.Iibhetri zeNiCad zinecadmium, isinyithi esinzima esinetyhefu enokuba yingozi kwimpilo yabantu nakwindalo esingqongileyo.Kwelinye icala, iibhetri zeNiMH azinazo naziphi na izinto ezinetyhefu kwaye zikhuseleke kakhulu ukuba zisetyenziswe.
3.Isantya sokuTshaja
Umahluko wesithathu phakathi kweebhetri zeNiCad kunye ne-NiMH sisantya sabo sokutshaja.Iibhetri zeNiCad zinokutshajwa ngokukhawuleza, kodwa zikwanengxaki koko kwaziwa ngokuba “yimpembelelo yenkumbulo.”Oku kuthetha ukuba ukuba ibhetri ayikhutshwanga ngokupheleleyo phambi kokuba itshajwe kwakhona, iyakukhumbula inqanaba elisezantsi kwaye ihlawuliswe kuphela ukuya kuthi ga kwelo nqanaba.Iibhetri ze-NiMH azikhathazeki kwimpembelelo yememori kwaye zinokuhlawuliswa nanini na ngaphandle kokunciphisa umthamo.
4.Ireyithi yokuZikhupha
Umahluko wesine phakathi kwebhetri ye-NiCad kunye ne-NiMH yizinga labo lokuzikhupha.Iibhetri ze-NiCad zinezinga eliphezulu lokuzikhupha kuneebhetri ze-NiMH, oku kuthetha ukuba zilahlekelwa yintlawulo yazo ngokukhawuleza xa zingasetyenziswa.Iibhetri zeNiCad zinokulahlekelwa ukuya kuthi ga kwi-15% yentlawulo yazo yenyanga, ngelixa iibhetri ze-NiMH zinokulahlekelwa ukuya kuthi ga kwi-5% ngenyanga.
5.Iindleko
Umahluko wesihlanu phakathi kweebhetri zeNiCad kunye ne-NiMH yindleko yazo.Iibhetri zeNiCad zikholisa ukuba zingabizi kakhulu kuneebhetri zeNiMH, nto leyo ezenza zibe lukhetho olufikelelekayo kwabo bakuhlahlo lwabiwo-mali.Nangona kunjalo, iibhetri ze-NiMH zinomthamo ophezulu kunye neengxaki ezimbalwa zokuzikhupha, ukwenzela ukuba zibe nexabiso leendleko ezongezelelweyo ekuhambeni kwexesha.
6.Ubushushu
Umahluko wesithandathu phakathi kweebhetri zeNiCad kunye ne-NiMH bubushushu babo bobushushu.Iibhetri zeNiCad zenza ngcono kubushushu obubandayo, ngelixa iibhetri zeNiMH zenza ngcono kubushushu obufudumeleyo.Ngoko ke, kuxhomekeke kwisicelo esicetywayo, uhlobo olulodwa lunokufaneleka ngakumbi.
7.Ubuhlobo bendalo
Ekugqibeleni, umahluko wesixhenxe phakathi kweebhetri ze-NiCad kunye ne-NiMH bubuhlobo babo bendalo.Iibhetri zeNiCad zinecadmium, isinyithi esinzima esinetyhefu, kwaye inokuba yingozi kwindalo esingqongileyo ukuba ayilahlwanga kakuhle.Iibhetri ze-NiMH, ngokuchaseneyo, azinazo izinto ezinetyhefu kwaye zikhuselekile kakhulu ukuzisebenzisa nokulahla.
Ukuqukumbela
Ukuqukumbela, iibhetri zeNiCad kunye neNiMH zombini iibhetri ezinokutshajwa, kodwa zahluke ngeendlela ezininzi.Iibhetri zeNiCad zinomthamo ophantsi kwaye zixhomekeke ngakumbi kwimpembelelo yememori, ngelixa iibhetri ze-NiMH zinomthamo ophezulu kwaye azikhathazeki kwimpembelelo yememori.Iibhetri zeNiCad nazo zinexabiso eliphantsi kwaye zisebenza ngcono kubushushu obubandayo, ngelixa iibhetri zeNiMH zibiza kakhulu kwaye zisebenza ngcono kumaqondo obushushu.Ekugqibeleni, iibhetri zeNiCad ziyingozi ngakumbi kwindalo, ngelixa iibhetri zeNiMH zingenazo izinto ezinobuthi.Ekugqibeleni, loluphi uhlobo olukhethayo luxhomekeke kwiimfuno zakho kunye nesicelo esicetywayo.
