Ngenxa yokusetyenziswa kwenani elikhulu leebhetri ze-nickel-cadmium (Ni-Cd) kwi-cadmium inetyhefu, kangangokuba ukulahlwa kweebhetri zenkunkuma kunzima, okusingqongileyo kungcolisiwe, ngoko ke kuya kwenziwa kancinci kancinci ngeebhetri ze-hydrogen storage alloy nickel-metal hydride ezinokutshajwa (Ni-MH) ukuze zithathelwe indawo.
Ngokuphathelele amandla ebhetri, ubungakanani obufanayo beebhetri ze-nickel-metal hydride ezinokutshajwa kwakhona kuneebhetri ze-nickel-cadmium malunga ne-1.5 ukuya kwi-2, kwaye akukho ungcoliseko lwe-cadmium, lusetyenziswe kakhulu kunxibelelwano oluphathwayo, kwiikhompyutha ze-notebook nakwezinye izixhobo ezincinci ze-elektroniki eziphathwayo.
Iibhetri ze-nickel-metal hydride ezinomthamo ophezulu ziqalile ukusetyenziswa kwizithuthi zepetroli/zombane ezixutyiweyo, ukusetyenziswa kweebhetri ze-nickel-metal hydride kunokutshajwa ngokukhawuleza kwaye kukhutshwe inkqubo, xa imoto isebenza ngesantya esiphezulu, iijenereyitha zinokugcinwa kwiibhetri ze-nickel-metal hydride zemoto, xa imoto isebenza ngesantya esiphantsi, zihlala zitya ipetroli eninzi kunesimo sesantya esiphezulu, ngoko ke ukuze kongiwe ipetroli, ngeli xesha, ingasetyenziselwa ukuqhuba i-electric motor yeebhetri ze-nickel-metal hydride endaweni yomsebenzi wenjini yokutsha yangaphakathi. Ukuze kongiwe ipetroli, ibhetri ye-nickel-metal hydride esebhodini ingasetyenziselwa ukuqhuba i-electric motor endaweni ye-engine yokutsha yangaphakathi, engagcini nje ngokuqinisekisa ukuqhuba okuqhelekileyo kwemoto, kodwa ikwagcina ipetroli eninzi, ke ngoko, iimoto ezixutyiweyo zinamandla amakhulu emarike xa kuthelekiswa nengqiqo yesiqhelo yemoto, kwaye amazwe kwihlabathi liphela anyusa uphando kule ndawo.
Imbali yophuhliso lwebhetri ye-NiMH ingahlulwahlulwa ibe ngamanqanaba alandelayo:
Inqanaba lokuqala (ekuqaleni kweminyaka yoo-1990 ukuya phakathi kwiminyaka yoo-2000): ubuchwepheshe bebhetri ye-nickel-metal hydride bukhula kancinci kancinci, kwaye usetyenziso lwezorhwebo luyanda kancinci kancinci. Zisetyenziswa kakhulu kwiimveliso ezincinci ze-elektroniki eziphathwayo ezifana neefowuni ezingenazingcingo, iikhompyutha zelaptop, iikhamera zedijithali kunye nezixhobo zesandi eziphathwayo.
Isigaba esiphakathi (phakathi kweminyaka yoo-2000 ukuya ekuqaleni kweminyaka yoo-2010): Ngophuhliso lwe-intanethi yeselula kunye nokwanda kwezixhobo ze-smart terminal ezifana neefowuni ezihlakaniphileyo kunye neePC zethebhulethi, iibhetri zeNiMH zisetyenziswa kakhulu. Kwangaxeshanye, ukusebenza kweebhetri zeNiMH nako kuphuculwe ngakumbi, ngokwanda koxinano lwamandla kunye nobomi bomjikelo.
Inqanaba lakutshanje (phakathi kweminyaka yoo-2010 ukuza kuthi ga ngoku): Iibhetri ze-nickel-metal hydride ziye zaba zezinye zeebhetri zamandla eziphambili kwizithuthi zombane kunye nezithuthi ezixutyiweyo. Ngokuqhubeka kweteknoloji, uxinano lwamandla eebhetri ze-NiMH luye lwaphuculwa rhoqo, kwaye ukhuseleko kunye nobomi bomjikelo nazo ziye zaphuculwa ngakumbi. Okwangoku, ngokwazi okwandayo kwihlabathi liphela ngokhuseleko lokusingqongileyo, iibhetri ze-NiMH nazo ziyathandwa ngenxa yeempawu zazo ezingangcolisiyo, ezikhuselekileyo nezizinzileyo.
