Ukwethulwa Okuyisisekelo Kwebhethri ye-NiMH (Ibhethri ye-Nickel-Metal Hydride)
IIbhethri ye-NiMhiwuhlobo lwebhethri lesibili elifana nebhethri le-NiCd.Ingashajwa futhi ingasetshenziswa izikhathi eziningi.Ngakho-ke, ibhethri ye-NiMH iwuhlobo lwebhethri elivumelana nemvelo kakhudlwana elisebenza kahle uma liqhathaniswa nebhethri le-alkaline elivamile noma ibhethri le-NiCd, okulenza lamukelwe kahle emakethe.Isibonelo, amabhethri e-NiMH asetshenziswa kakhulu kumakhamera edijithali, omakhalekhukhwini, ama-camcorder, ama-shaver, ama-transceiver, nezinye izinto zikagesi.
Izinga lemboni le-voltage elinganiselwe yeseli ye-NiMH ngu-1.2 volts.Empeleni, amabhethri e-NiMH ahlukaniswe ngamabhethri e-NiMH ane-voltage ephezulu kanye namabhethri e-NiMH ane-voltage ephansi.I-electrode ephozithivu yebhethri ye-NiMH yi-Ni(OH)2 (ebuye ibizwe ngokuthi i-nickel-oxide hydroxide), futhi i-electrode eyinegethivu yebhethri ye-NiMH yenziwe nge-alloy emunca i-hydrogen.
Umlando Webhethri ye-NiMH (Ibhethri le-Nickel-Metal Hydride)
Ukukhulelwa kwebhethri le-NiMh kwaqala ukuphakanyiswa ngawo-1970, ngocwaningo oluningi olwagxila eminyakeni yawo-1980 kanye nokukhiqizwa kwezimboni kuqala ukubonakala ekuqaleni kwawo-1990.Amabhethri e-NiMH ekuqaleni abengamanye amabhethri e-NiCad, egwema ukusebenzisa into enobuthi ethi 'cadmium' futhi eqeda izingozi zemvelo ezibangelwa izinsimbi ezisindayo ekuphileni kwethu kwansuku zonke.Amabhethri e-NiMH aqala ukwenziwa ngezimboni eJapan, e-United States, eJalimane nakwamanye amazwe.
Ngakolunye uhlangothi, ngokuthuthukiswa kwebhethri ye-Lithium Ion kanye nobunye ubuchwepheshe obusha endaweni yamandla aluhlaza, ibhethri ye-NiMH kancane kancane yalahlekelwa isisindo kwezinye izindawo ngenxa yokungalungi kwayo.Amabhethri e-NiMH asekuqaleni ayesetshenziswa kakhulu ukufaka amabhethri e-NiCd kumakhompiyutha ezincwadi nomakhalekhukhwini.Kusukela ekudayiseni amabhethri e-Li-ion ngeminyaka yawo-1990, amabhethri e-Li-ion athathe indawo yamabhethri e-NiMH, futhi athathe imakethe yezinto zikagesi eziphathwayo iminyaka engaphezu kweyishumi kusukela ngaleso sikhathi.
Kodwa-ke, ubuchwepheshe be-NiMH abuzange buhlale bumile ngokungafani nezinhlelo zokusebenza zabathengi, lapho i-Lithium-ion ishintshe kakhulu i-NiMH.Ubuchwepheshe be-NiMH buyenzeka ekusetshenzisweni kwezimoto.Ubuchwepheshe obuncanyelwayo bokuhlinzeka ngogesi kuma-HEV futhi buqongelele eminyakeni eyi-10 yokusebenzisa okungenazinkinga.Ngenxa yalokho, ingahlala impilo yonke yemoto.Ibanga lokushisa elisebenzayo lamaseli e-NiMH lenyuselwe cishe ku-100 °C (-30 °C kuya ku-+ 75 °C), eliphakeme kakhulu kunebanga lokushisa elingakhonakala kumaseli e-Lithium.Lokhu kwenza ubuchwepheshe be-NiMH busebenze kahle ezimotweni.Izithako ezisebenzayo ku-NiMH ngokwemvelo ziphephile kunalezo ezikumaseli asekelwe ku-Lithium, futhi amabhethri e-NiMH awatholi imiphumela yenkumbulo.Amabhethri e-NiMH awadingi amasistimu okuphatha ibhethri (i-BMS) adingwa amabhethri e-lithium, futhi angakwazi ukumelana nesici samazinga aphezulu wamandla wezinhlelo zokusebenza ze-EV futhi abe namakhemikhali asebenzayo aphephe ngokuyisisekelo kunalawo atholakala kumaseli asekelwe ku-Lithium.Esikhathini esizayo esiseduze, ibhethri ye-NiMH izodlala indima ebalulekile endaweni ye-EV ngalezo zinzuzo.
I-Electrochemistry yebhethri ye-NiMH
Ibhethri le-NiMH lisebenza kumgomo osuselwe ekumunceni, ekukhishweni nasekuthuthweni kweHydrojeni ngaphakathi kwama-electrode amabili.
I-electrode enhle:
Ni(OH)2+OH-=NiOOH+H2O+e-
I-electrode engalungile:
M+H2O+e-=MHab+OH-
Ukusabela sekukonke:
Ni(OH)2+M=NiOOH+MH
Lokhu kusabela kuyabuyiseleka emuva ngesikhathi sokushaja, futhi izibalo zizogeleza ukusuka kwesokudla kuye kwesokunxele.
Izinhlelo zokusebenza zebhethri le-NiMH
Amabhethri e-NiMH asetshenziswa kabanzi emkhakheni wamathuluzi kagesi, amakhamera edijithali, izimoto zikagesi, namanye amadivaysi.Ngaphandle kwalokho, amabhethri e-NiMH asebenza kahle kakhulu ekushiseni okuphansi futhi afaneleka ekukhishweni okuphezulu kwamanje, ngakho-ke avame ukuqoqelwa kumaphakethe ebhethri e-NiMH ukuze ahlangabezane nezidingo zamadivayisi kagesi aphathekayo, njengamaphrinta aphathekayo, amathuluzi kagesi, imikhiqizo yedijithali, nogesi. amathoyizi, njll.
Izici ezihlanganisiwe zamabhethri e-NiMH, njengokuqina kwamandla aphezulu, amandla aphezulu futhi akukho ukungcola, futhi ziwenza afanelekele ukusetshenziswa njengamabhethri kagesi, futhi ezinye izimboni zebhethri ze-NiMH ziwasebenzise ukuthuthukisa ukusetshenziswa kwebhethri ye-NiMH yama-EVs, izithuthuthu zikagesi namabhayisikili kagesi. .Lesi sici siphinde sanwetshwa kwezempi, ngezinhlelo zokusebenza kumandla okulondoloza ikhophi yezokuxhumana, ubuchwepheshe besikhala, amarobhothi, nemikhumbi-ngwenya.
Ukusetshenziswa Nokugcinwa Kwamabhethri e-NiMH
Amabhethri e-NiMH kufanele asetshenziswe ngokunaka ukunakekelwa.
Gwema ukushaja ngokweqile ohlelweni lokusebenzisa.Ngaphakathi kwempilo yomjikelezo, inqubo yokusebenzisa akufanele ikhokhiswe ngokweqile ngoba ukushaja ngokweqile kungenzeka kwenze ama-electrode aphozithivu nenegethivu akhukhumale, kubangele ukuthi impahla esebenzayo ziwe kanye ne-diaphragm yonakaliswe, inethiwekhi yokuqhuba izobhujiswa, kanye nebhethri i-ohmic. i-polarization ukuze ibe mkhulu.
Ukulondolozwa kwamabhethri e-NiMH kufanele kwenziwe ngemva kokushajwa okwanele.Uma amabhethri egcinwa isikhathi eside ngaphandle kokukhokhiswa okwanele, umsebenzi we-electrode hydrogen storage alloy uzoba buthakathaka futhi impilo yebhethri izofinyezwa.
Kungani Khetha i-Weijiang Njengomkhiqizi Webhethri we-NiMH?
E-China, amabhethri e-NiMH athole ukuthuthukiswa okusheshayo emashumini ambalwa eminyaka adlule.Ngo-2006, i-China yakhiqiza amabhethri e-NiMH ayizigidi eziyizinkulungwane ezingu-1.3, idlula iJapane njengomkhiqizi omkhulu kunabo bonke emhlabeni.I-China inamaphesenti angama-70 ezindawo ezigcina umhlaba eziyivelakancane, okuwumthombo oyinhloko webhethri ye-NiMH ye-anode hydrogen storage alloy.Lokho kungasiza ukunciphisa izindleko zokukhiqiza zamabhethri e-NiMH e-China.
Umgomo wethu uwukunikeza amandla e-NiMH aphephile, athembekile futhi athengekayo alungiselelwe izidingo zemikhiqizo yakho.Ngokugxila ekwenzeni ngokwezifiso, uhla lwethu olugcwele lwezinsizakalo zebhethri le-NiMH ezenziwe ngokwezifiso ziqinisekisa ukuthi amabhethri ethu e-NiMH afanelekela izidingo zakho ngaphandle komthungo, njengengokwezifiso Ibhethri le-NiMH, ngokwezifiso ibhethri ye-AA NiMH, ngokwezifiso ibhethri ye-AAA NiMH, ngokwezifiso ibhethri le-C NiMH, ngokwezifiso ibhethri le-D NiMH, ngokwezifiso ibhethri le-9V NiMH, ngokwezifiso ibhethri le-F NiMH, cIbhethri le-ustom le-Sub C NiMH futhiiphakethe lebhethri le-NiMH elenziwe ngokwezifiso.Sisebenzisana nawe ukuze sizuze ukuqonda okujulile kwezidingo nezinselelo zakho, bese sithuthukisa izixazululo ezihambisana nokucaciswa kwakho.
