Uma ukhuluma ngamabhethri ashajwa kabusha, ibhethri le-NiCad kanye neIbhethri ye-NiMHziyizinhlobo ezimbili zebhethri ethandwa kakhulu endaweni yabathengi kanye nezimboni.Ibhethri le-NiCad bekungenye yenketho engcono kakhulu yebhethri elishajekayo.Kamuva, ibhethri ye-NiMH ishintshile kancane kancane ibhethri ye-NiCad ezindaweni zabathengi nezimboni ngezinzuzo zayo.Namuhla, ibhethri le-NiMH lidume kakhulu kunebhethri le-NiCad kwezinye izindawo.
Isingeniso Esiyisisekelo samabhethri e-NiCad
Amabhethri e-NiCad (Nickel Cadmium) angelinye lamabhethri amadala aphinde ashajwe, abekhona kusukela ngasekupheleni kwekhulu le-19.Akhiwe nge-nickel oxide hydroxide ne-cadmium futhi asebenzisa i-alkaline electrolyte.Amabhethri e-NiCad ngokuvamile asetshenziswa kumadivayisi adonsa kancane njengamafoni angenazintambo, amathuluzi kagesi, namathoyizi kagesi.
Enye yezinzuzo eziyinhloko zamabhethri e-NiCad ukuthi awabizi uma kuqhathaniswa nezinye izinhlobo zamabhethri.Ukwengeza, banomthamo omkhulu wamandla, okusho ukuthi bangagcina amandla amaningi endaweni encane.Amabhethri e-NiCad nawo anokugcinwa kokushajwa okuhle, okusho ukuthi angakwazi ukushaja isikhathi eside ngisho noma engasetshenziswa.
Ngeshwa, amabhethri e-NiCad anezinkinga ezithile ezinkulu.Okunye okubaluleke kakhulu ukuthi bahlushwa “umphumela wenkumbulo”, okusho ukuthi uma ibhethri likhishwa kancane bese lishajwa kabusha, lizobamba ishaji eliyingxenye ngokuzayo futhi lilahlekelwe amandla ngokuhamba kwesikhathi.Umthelela wenkumbulo ungancishiswa ngokuphathwa kwebhethri ngendlela efanele.Nokho, kuseyinkinga kubasebenzisi abaningi.Ukwengeza, amabhethri e-NiCad anobuthi futhi kufanele agaywe kabusha noma alahlwe ngendlela efanele.
Isingeniso Esiyisisekelo samabhethri e-NiMH
Amabhethri e-NiMH (Nickel Metal Hydride) athuthukiswa ngasekupheleni kwawo-1980 futhi asheshe aduma ngenxa yokusebenza kwawo okuthuthukisiwe ngamabhethri e-NiCad.Akhiwe nge-nickel ne-hydrogen futhi asebenzisa i-alkaline electrolyte, efana namabhethri e-NiCad.Amabhethri e-NiMH avame ukusetshenziswa kumadivayisi akhipha amanzi amaningi njengamakhamera edijithali, ama-camcorder, nama-consoles wegeyimu ephathekayo.
Enye yezinzuzo eziyinhloko zamabhethri e-NiMH ukuthi awakhathazwa yimiphumela yenkumbulo, okusho ukuthi angashajwa kungakhathaliseki ukuthi akhishwe kangakanani.Lokhu kuzenza zilungele amadivayisi adinga ukushajwa njalo, njengamakhamera edijithali noma amakhompyutha aphathekayo.Amabhethri e-NiMH anobuthi obuncane kunamabhethri e-NiCad futhi angalahlwa ngokuphephile ngaphandle kokulimaza imvelo.
Ngaphandle kwalezi zinzuzo, amabhethri e-NiMH anezinkinga ezithile.Okunye okubaluleke kakhulu ukuthi abiza kakhulu kunamabhethri e-NiCad.Ukwengeza, banesisindo esincane samandla, okusho ukuthi badinga isikhala esiningi ukuze bagcine inani elifanayo lamandla.Okokugcina, amabhethri e-NiMH anempilo yeshelufu emifushane kunamabhethri e-NiCad, okusho ukuthi alahlekelwa ukushajwa kwawo ngokushesha uma engasetshenziswa.
Umehluko Phakathi Kwebhethri Le-NiCad Nebhethri Le-NiMH
Umehluko phakathi kwebhethri le-NiCad nebhethri le-NiMH ungadida abantu abaningi, ikakhulukazi lapho bekhetha elifanele izidingo zabo.Zombili lezi zinhlobo zamabhethri zinezinzuzo kanye nokubi zazo, ngakho-ke kubalulekile ukuqonda ukuthi ziyini ukuze wenze isinqumo unolwazi ngokuthi iyiphi elungele kangcono izidingo zakho, kungaba kumthengi noma endaweni yezimboni.Kulesi sihloko, sizoxoxa ngomehluko phakathi kwamabhethri e-NiCad ne-NiMH, kanye nezinzuzo nezingozi zabo.Nakuba zibonakala zifana, zisenomehluko ohlukile emandleni, umphumela wenkumbulo, nokunye.
1.Amandla
Umehluko omkhulu phakathi kwamabhethri e-NiMH ne-NiCad amandla awo.Ibhethri le-NiMH linomthamo omkhulu kunebhethri le-NiCad.Ukusebenzisa ibhethri le-NiCad endaweni yezimboni akunconywa ngomthamo walo ophansi.Ngokuvamile, umthamo webhethri le-NiMH uphakeme izikhathi ezi-2-3 kunebhethri le-NiCad.Amabhethri e-NiCad avamise ukuba namandla okuzisholo angu-1000 mAh (amahora angu-milliamp), kuyilapho amabhethri e-NiMH angaba nomthamo ofika ku-3000 mAh.Lokhu kusho ukuthi amabhethri e-NiMH angagcina amandla amaningi futhi ahlale isikhathi eside kunamabhethri e-NiCad.
2.I-Chemistry
Omunye umehluko phakathi kwamabhethri e-NiCad ne-NiMH yikhemikhali yawo.Amabhethri e-NiCad asebenzisa i-nickel-cadmium chemistry, kuyilapho amabhethri e-NiMH esebenzisa i-nickel-metal hydride chemistry.Amabhethri e-NiCad aqukethe i-cadmium, insimbi esindayo enobuthi engaba yingozi empilweni yomuntu nasendaweni ezungezile.Ngakolunye uhlangothi, amabhethri e-NiMH awaqukethe izinto ezinobuthi futhi aphephe kakhulu ukuwasebenzisa.
3.Isivinini sokushaja
Umehluko wesithathu phakathi kwamabhethri e-NiCad ne-NiMH yijubane lokushaja kwawo.Amabhethri e-NiCad angashajwa ngokushesha, kodwa futhi ahlushwa yilokho okwaziwa ngokuthi “umphumela wenkumbulo.”Lokhu kusho ukuthi uma ibhethri lingashajwa ngokugcwele ngaphambi kokushajwa, lizokhumbula izinga eliphansi futhi lishaje kuze kufike kulelo phuzu.Amabhethri e-NiMH awakhathazwa wumphumela wenkumbulo futhi angashajwa noma nini ngaphandle kokunciphisa umthamo.
4.Isilinganiso Sokuzikhipha
Umehluko wesine phakathi kwebhethri le-NiCad ne-NiMH izinga lokuzikhipha.Amabhethri e-NiCad anenani eliphakeme lokuzikhulula kunamabhethri e-NiMH, okusho ukuthi alahlekelwa ukushajwa kwawo ngokushesha uma engasetshenziswa.Amabhethri e-NiCad angalahlekelwa kufika ku-15% wenkokhiso yawo yanyanga zonke, kuyilapho amabhethri e-NiMH angalahlekelwa kufika ku-5% ngenyanga.
5.Izindleko
Umehluko wesihlanu phakathi kwamabhethri e-NiCad ne-NiMH yizindleko zawo.Amabhethri e-NiCad avame ukushibhile kunamabhethri e-NiMH, okuwenza abe inketho ethengekayo kulawo asebhajethi.Kodwa-ke, amabhethri e-NiMH anomthamo ophezulu kanye nezinkinga ezimbalwa zokuzikhipha, ukuze afanelekele izindleko ezengeziwe ngokuhamba kwesikhathi.
6.Izinga lokushisa
Umehluko wesithupha phakathi kwamabhethri e-NiCad ne-NiMH ukuzwela kwawo kwezinga lokushisa.Amabhethri e-NiCad enza kangcono emazingeni okushisa abandayo, kuyilapho amabhethri e-NiMH enza kangcono emazingeni okushisa afudumele.Ngakho-ke, kuye ngohlelo oluhlosiwe, uhlobo olulodwa lungase lufaneleke kangcono.
7.Ubungane Bemvelo
Ekugcineni, umehluko wesikhombisa phakathi kwebhethri ye-NiCad ne-NiMH ubungane babo bemvelo.Amabhethri e-NiCad aqukethe i-cadmium, insimbi esindayo enobuthi, futhi angaba yingozi endaweni ezungezile uma engalahlwanga kahle.Ngokuphambene, amabhethri e-NiMH awaqukethe izinto ezinobuthi futhi aphephe kakhudlwana ukuwasebenzisa nokulahlwa.
Isiphetho
Sengiphetha, amabhethri e-NiCad ne-NiMH womabili amabhethri aphinde ashajwe, kodwa ahluka ngezindlela ezimbalwa.Amabhethri e-NiCad anomthamo ophansi futhi athambekele kakhulu kumphumela wenkumbulo, kuyilapho amabhethri e-NiMH enomthamo ophakeme futhi engahlushwa umphumela wenkumbulo.Amabhethri e-NiCad nawo ashibhile futhi enza kangcono emazingeni okushisa abandayo, kuyilapho amabhethri e-NiMH ebiza kakhulu futhi enza kangcono emazingeni okushisa afudumele.Okokugcina, amabhethri e-NiCad ayingozi kakhulu emvelweni, kuyilapho amabhethri e-NiMH angenazo izinto ezinobuthi.Ekugcineni, yiluphi uhlobo olukhethayo luncike ezidingweni zakho kanye nesicelo esihlosiwe.
