Emhlabeni wobuchwepheshe bebhethri,amabhethri e-nickel-metal hydride (NiMH).kanye namabhethri e-lithium-ion (Li-ion) ayizinketho ezimbili ezithandwayo. Uhlobo ngalunye lunikeza izinzuzo ezihlukile, okwenza ukukhetha phakathi kwazo kube okubalulekile ezinhlobonhlobo zezinhlelo zokusebenza. Lesi sihloko sinikeza ukuqhathanisa okuphelele kwezinzuzo zamabhethri e-NiMH ngokumelene namabhethri e-Li-ion, kuyilapho kucutshungulwa isidingo semakethe yomhlaba wonke namathrendi.
Amabhethri e-NiMH aqhosha ngokuminyana kwamandla aphezulu, okusho ukuthi angagcina amandla engeziwe. Ukwengeza, ashaja ngokushesha futhi anesikhathi eside sokuphila uma kuqhathaniswa nezinye izinhlobo zebhethri. Lokhu kuhumusha esikhathini esincane esichithwe ukushaja nokusebenza okuhlala isikhathi eside okuvela ebhethrini. Ngaphezu kwalokho, amabhethri e-NiMH anomthelela omncane kwezemvelo ngenxa yokuntuleka kwawo kwezinto eziyingozi njenge-cadmium.
Ngakolunye uhlangothi, amabhethri e-Li-ion anikeza izinzuzo eziningana. Okokuqala, banokuminyana kwamandla okuphezulu nakakhulu, okuvumela amandla engeziwe ephaketheni elincane. Lokhu kubenza bafaneleke kumadivayisi ahlangene adinga isikhathi eside sokusebenza. Okwesibili, ama-electrode awo kanye namakhemikhali anikeza isikhathi eside sokuphila uma kuqhathaniswa namabhethri e-NiMH. Futhi, usayizi wabo omncane uvumela amadivayisi athambile, aphatheka kakhudlwana.
Uma kuziwa ekuphepheni, zombili izinhlobo zebhethri zinokucabangela kwazo. NgenkathiAmabhethri e-NiMHangabangela ingozi yomlilo ngaphansi kwezimo ezimbi kakhulu, amabhethri e-Li-ion anomkhuba wokushisa ngokweqile futhi abambe umlilo uma eshajwe ngokungalungile noma ngenxa yomonakalo. Ngakho-ke, izinyathelo ezifanele zokunakekela nezokuphepha zibalulekile uma usebenzisa zombili izinhlobo zamabhethri.
Uma kukhulunywa ngesidingo somhlaba wonke, isithombe siyahlukahluka kuye ngesifunda. Amazwe athuthukile njenge-US ne-Europe athambekele ekuthandeni amabhethri e-Li-ion kuma-electronics awo asezingeni eliphezulu njengama-smartphone, amaphilisi, namakhompyutha aphathekayo. Ngaphezu kwalokho, ngengqalasizinda yokushaja esunguliwe kulezi zifunda, amabhethri e-Li-ion nawo athola ukusetshenziswa ezimotweni zikagesi (EVs) kanye namahybrids.
Ngakolunye uhlangothi, amazwe ase-Asia afana ne-China ne-India athanda amabhethri e-NiMH ngenxa yokungabizi kwawo kanye nokushaja kalula. Lawa mabhethri asetshenziswa kakhulu kumabhayisikili kagesi, amathuluzi kagesi, nasezintweni zasendlini. Futhi, njengoba ingqalasizinda yokushaja e-Asia iqhubeka nokuthuthukiswa, amabhethri e-NiMH nawo athola ukusetshenziswa kuma-EV.
Sekukonke, amabhethri e-NiMH kanye ne-Li-ion ngalinye linikeza izinzuzo ezihlukile kuye ngohlelo lokusebenza nendawo. Njengoba imakethe ye-EV ikhula emhlabeni wonke futhi ama-electronics abathengi avela, isidingo samabhethri e-Li-ion kulindeleke ukuthi sikhule. Khonamanjalo, njengoba ubuchwepheshe buthuthuka nezindleko zehla,Amabhethri e-NiMHbangagcina ukuthandwa kwabo emikhakheni ethile.
Sengiphetha, lapho ukhetha phakathi kwamabhethri e-NiMH ne-Li-ion, kubalulekile ukucabangela izidingo zakho ezithile: ukuminyana kwamandla, ubude besikhathi sokuphila, ukulinganiselwa kosayizi, kanye nezidingo zebhajethi. Ukwengeza, ukuqonda okuthandwayo kwesifunda kanye namathrendi emakethe kungasiza ukwazisa isinqumo sakho. Njengoba ubuchwepheshe bebhethri buqhubeka nokuvela, kungenzeka ukuthi womabili amabhethri e-NiMH ne-Li-ion azohlala eyizinketho ezibalulekile zezinhlelo zokusebenza ezihlukahlukene esikhathini esizayo.
