Njengoba sibhekela ekusaseni elihlanzekile neliluhlaza, isidingo sezixazululo ezisebenza kahle nezisimeme zokugcina amandla sikhula ngokushesha.Obunye bobuchwepheshe obuthembisayo amabhethri e-lithium-ion, athola ukuduma ngenxa yokuminyana kwawo okuphezulu nempilo ende uma kuqhathaniswa namabhethri e-lead-asidi evamile.Ngaphakathi kweibhethri ye-lithium-ionumndeni, izinhlobo ezimbili eziyinhloko ezivame ukuqhathaniswa amabhethri e-lithium iron phosphate (LiFePO4) namabhethri e-lithium ternary.Ngakho-ke, ake sijule: iyiphi engcono?
Mayelana namabhethri e-lithium iron phosphate
Amabhethri e-Lithium iron phosphate (LiFePO4) aziwa ngokuzinza kwawo, ukuphepha, nempilo yomjikelezo omude.Ibhethri elishajwa kabusha elisebenzisa i-lithium ion ukugcina nokukhulula amandla phakathi nemijikelezo yokushaja nokukhipha.Uma kuqhathaniswa namabhethri e-lithium e-ternary, amabhethri e-lithium iron phosphate anomthamo omncane wamandla, kodwa ukuzinza kwawo nempilo yawo kwenza lokhu kuntuleka.Lawa mabhethri anokuqina okuphezulu kokushisa, okuwenza amelana nokushisa ngokweqile futhi anciphise ingozi yokubaleka okushisayo, ukukhathazeka okubalulekile kwezinhlelo zokusebenza eziningi.Ukwengeza, amabhethri e-LiFePO4 angakwazi ukumelana nokushajwa okuphezulu kakhulu nokujikeleza kwemijikelezo, kuze kufike kumjikelezo we-2000 noma ngaphezulu, okuwenza alungele isikhathi eside, izinhlelo zokusebenza ezisebenza kahle njengezimoto zikagesi (EVs).
Mayelana namabhethri e-ternary lithium
Ngakolunye uhlangothi, amabhethri e-lithium e-ternary, aziwa nangokuthi i-lithium nickel-cobalt-aluminium oxide (NCA) noma amabhethri e-lithium nickel-manganese-cobalt oxide (NMC), anikeza ukuminyana kwamandla okuphezulu kunamabhethri e-LiFePO4.Ukuminyana kwamandla okuphezulu kuvumela umthamo omkhulu wesitoreji kanye nesikhathi sokusebenza sedivayisi esingaba side.Ukwengeza, amabhethri e-lithium e-ternary ngokuvamile anikela ngokukhipha amandla aphezulu, okuwenza afanelekele izinhlelo zokusebenza ezidinga ukuqhuma okusheshayo kwamandla, njengamathuluzi kagesi noma ama-electronics abathengi.Nokho, njengoba ukuminyana kwamandla kwanda, kukhona ukuhwebelana.Amabhethri e-Ternary lithium angase abe nempilo yesevisi emfushane futhi athambekele kakhulu ezinkingeni ezishisayo nokungazinzi kunamabhethri e-LiFePO4.
Ukunquma ukuthi yiliphi ibhethri elingcono ekugcineni kuncike ezidingweni zohlelo oluthile.Lapho ukuphepha nokuphila isikhathi eside kuyizinto eziza kuqala, njengasezimotweni zikagesi noma izinhlelo zamandla avuselelekayo, amabhethri e-lithium iron phosphate ayinketho yokuqala.Ukuzinza, impilo yomjikelezo omude, nokumelana nokubaleka okushisayo kwamabhethri e-LiFePO4 kuwenza abe yisinqumo esihle kakhulu sezinhlelo zokusebenza ezibucayi lapho ukuphepha kubaluleke kakhulu.Ngaphezu kwalokho, ezinhlelweni zokusebenza ezidinga ukuphuma kwamandla okuqhubekayo okuphezulu noma lapho isisindo nesikhala kuyizici ezibalulekile, amabhethri e-lithium e-ternary angaba yinketho efanelekile ngenxa yokuminyana kwawo okuphezulu kwamandla.
Zombili izinhlobo zamabhethri zinezinzuzo kanye nokubi, futhi izimfuneko ezithile zesicelo kufanele zicatshangelwe ngokucophelela ngaphambi kokwenza isinqumo.Izinto ezinjengokuphepha, impilo yonke, ukuminyana kwamandla, ukuphuma kwamandla, kanye nezindleko konke kufanele kucatshangelwe.
Ukufingqa, akekho owinile osobala engxoxweni phakathi kwamabhethri e-lithium iron phosphate namabhethri e-ternary lithium.Indlela ngayinye inezinzuzo nezinkinga zayo, futhi ukukhetha kuncike ezidingweni zesicelo esithile.Njengoba ubuchwepheshe buqhubeka buthuthuka, zombili izinhlobo zamabhethri e-Li-ion ngokungangabazeki zizothuthuka ngokusebenza, ukuphepha nokusebenza kahle okuphelele.Kungakhathaliseki ukuthi iliphi ibhethri ogcina ulikhetha, kubalulekile ukuqhubeka nokwamukela kanye nokutshala imali ezisombululweni zokugcina amandla ezisimeme nezivumelana nemvelo ezifaka isandla ekusaseni eliluhlaza kubo bonke.
Uma uthanda amabhethri e-lithium, wamukelekile ukuthintana nenkampani yebhethri ye-lithium Radiance ukuzeFunda kabanzi.
