I-Nickel-Metal Hydride (ibhetri ye-NiMH) iteknoloji yebhetri ehlawulelwayo esebenzisa i-nickel hydride njengento engafanelekanga ye-electrode kunye ne-hydride njengento efanelekileyo ye-electrode. Luhlobo lwebhetri olwalusetyenziswa ngokubanzi phambi kweebhetri ze-lithium-ion.
Iibhetri ezinokutshajwa kwakhona ziye zadlala indima ebaluleke kakhulu kwezinye iindawo kunye nezixhobo ezithile, ezifana nezixhobo zombane eziphathwayo, i-hybrid kunye nezithuthi zombane, iinkqubo zokugcina amandla, ukukhanya okungxamisekileyo kunye namandla okugcina.
Njengeebhetri zokuqala ezitshajwayo, iibhetri zeNiMH zinezi zinto zilandelayo zibalulekileyo:
Uxinaniso lwamandla aphezulu:Iibhetri ze-NiMH zinoxinzelelo olukhulu lwamandla, olunokubonelela ngexesha elide lokusetyenziswa.
Ukumelana nobushushu obuphezulu:Xa kuthelekiswa nezinye iibhetri ezinokutshajwa kwakhona, iibhetri ze-NiMH zizinzile kwiimeko eziphezulu zokushisa.
Ixabiso eliphantsi:Xa kuthelekiswa nobunye ubuchwepheshe bebhetri obutsha obufana neebhetri ze-lithium-ion, iibhetri ze-NiMH azibizi kakhulu ukwenza.
Nangonaiibhetri ze-lithium-ion zithathe indawo yeebhetri ze-nickel-metal hydride kwizicelo ezininzi, iibhetri ze-nimh zisenokungabikho kwindawo ethile kwezinye iindawo ezithile. Umzekelo:
Ukusetyenziswa kokusingqongileyo kobushushu obuphezulu:xa kuthelekiswa neebhetri ze-Li-ion, iibhetri ze-NiMH zenza ngcono kwiindawo eziphezulu zokushisa. Banozinzo oluphezulu lwe-thermal kunye nokusebenza kokhuseleko, kwaye banokusebenza kumaqondo aphezulu aphezulu, ngelixa iibhetri ze-lithium-ion zinokugqithisa kunye ne-short-circuit kumaqondo aphezulu.
IiMfuno zoBomi obude:Iibhetri ze-NiMH zihlala ziphila ixesha elide kwaye zinokungena kwimijikelezo yentlawulo / yokukhupha ngaphandle kokuthotywa okubalulekileyo kokusebenza. Oku kunika iibhetri ze-NiMH inzuzo kwizicelo ezifuna ukusetyenziswa okuthembekileyo kwexesha elide, njenge-satellites, i-spacecraft kunye nezixhobo ezithile zoshishino.
Ukusetyenziswa komthamo ophezulu:Iibhetri ze-NiMH ngokuqhelekileyo zinomthamo ophezulu kwaye zifanelekile izixhobo kunye neenkqubo ezifuna ukugcinwa kwamandla aphezulu. Oku kubandakanya ezinye iinkqubo zokugcina amandla, izixhobo zombane ezingxamisekileyo kunye nezinye iindawo ezikhethekileyo zezixhobo.
Ixabiso lexabiso:Nangona iibhetri ze-Li-ion zikhuphisana ngakumbi ngokweendleko kunye nokuxinana kwamandla, iibhetri ze-NiMH zisenokuba nenzuzo yeendleko kwezinye iimeko ezithile. Ngokomzekelo, kwezinye izixhobo ezilula kunye nexabiso eliphantsi, iibhetri ze-NiMH zinokuba lukhetho olunoqoqosho ngakumbi.
Kubalulekile ukuba uqaphele ukuba njengoko iteknoloji iye yavela, iibhetri ze-Li-ion zineenzuzo kwiindawo ezininzi kwaye ziphumelele ukubusa kwizicelo ezininzi. Nangona kunjalo, iibhetri ze-NiMH zisadlala indima ebalulekileyo kwezinye iindawo kunye neemfuno, kunye nokuguquguquka kobushushu obuphezulu, ubomi obude, umthamo ophezulu kunye neenzuzo zeendleko zigcina zingenakulinganiswa kwizicelo ezithile.
