I-Nickel-Metal Hydride (ibhethri ye-NiMH) ubuchwepheshe bebhethri obushajekayo obusebenzisa i-nickel hydride njengento engasebenzi kahle ye-electrode kanye ne-hydride njengento esebenzayo ye-electrode. Iwuhlobo lwebhethri olwalusetshenziswa kabanzi ngaphambi kwamabhethri e-lithium-ion.
Amabhethri aphinde ashajwe abedlala indima ebaluleke kakhulu kwezinye izinkambu namadivayisi athile, njengamadivayisi kagesi aphathwayo, izimoto ezixubile nezikagesi, amasistimu okugcina amandla, izibani eziphuthumayo namandla ayisipele.
Njengamabhethri ajwayelekile ajwayelekile ashajwa kabusha, amabhethri e-NiMH anezici ezilandelayo ezibalulekile:
Ukuminyana kwamandla aphezulu:Amabhethri e-NiMH anomthamo omkhulu wamandla uma kuqhathaniswa, anganikeza isikhathi eside sokusebenzisa.
Ukumelana okuhle kwezinga lokushisa eliphezulu:Uma kuqhathaniswa namanye amabhethri aphinde ashajwe, amabhethri e-NiMH azinzile kakhulu ezimweni zokushisa eziphezulu.
Izindleko eziphansi:Uma kuqhathaniswa nobunye ubuchwepheshe obusha bebhethri obufana namabhethri e-lithium-ion, amabhethri e-NiMH ashibhile ukuwakhiqiza.
Nakubaamabhethri e-lithium-ion athathe indawo yamabhethri e-nickel-metal hydride ezinhlelweni eziningi, amabhethri e-nimh asenokungabuyiseleki okuthile kwezinye izindawo ezithile. Ngokwesibonelo:
Izinhlelo zokusebenza zemvelo yokushisa okuphezulu:uma kuqhathaniswa namabhethri e-Li-ion, amabhethri e-NiMH enza kangcono ezindaweni ezishisa kakhulu. Banokusimama okuphezulu kokushisa nokusebenza kokuphepha, futhi bangasebenza emazingeni okushisa aphezulu, kuyilapho amabhethri e-lithium-ion angase ashise kakhulu futhi abe ne-short-circuit emazingeni okushisa aphezulu.
Izidingo zempilo ende:Amabhethri e-NiMH ngokuvamile anempilo yomjikelezo omude futhi angabhekana nemijikelezo eyengeziwe yokushaja/yokukhipha ngaphandle kokuwohloka okuphawulekayo kokusebenza. Lokhu kunikeza amabhethri e-NiMH inzuzo ezinhlelweni ezidinga ukusetshenziswa okuthembekile kwesikhathi eside, njengamasathelayithi, imikhumbi-mkhathi kanye nemishini ethile yezimboni.
Izinhlelo zokusebenza eziphezulu:Amabhethri e-NiMH ngokuvamile anomthamo omkhulu uma kuqhathaniswa futhi afanele izinto zokusebenza namasistimu adinga ukugcinwa kwamandla aphezulu. Lokhu kuhlanganisa amasistimu okugcina amandla, izinsiza zikagesi eziphuthumayo kanye nezindawo ezikhethekile zemishini.
Isici sezindleko:Nakuba amabhethri e-Li-ion encintisana kakhulu ngokwezindleko nokuminyana kwamandla, amabhethri e-NiMH asengase abe nenzuzo yezindleko kwezinye izimo ezithile. Isibonelo, kwezinye izinto ezilula futhi ezingabizi kakhulu, amabhethri e-NiMH angaba ukukhetha ukonga kakhulu.
Kubalulekile ukuqaphela ukuthi njengoba ubuchwepheshe buye bavela, amabhethri e-Li-ion anezinzuzo ezindaweni eziningi futhi azuze ukubusa ezinhlelweni eziningi. Kodwa-ke, amabhethri e-NiMH asadlala indima ebalulekile kwezinye izindawo nezidingo ezithile, futhi ukuguquguquka kwawo kwezinga lokushisa eliphezulu, impilo ende, umthamo ophezulu kanye nezinzuzo zezindleko ziwagcina engenakushintshwa ezinhlelweni ezithile.
