Amabhethri e-sodium-ion: Ingabe angcono kunamabhethri e-lithium?
Eminyakeni yamuva nje, kuye kwaba nesithakazelo esikhulayo kumabhethri e-sodium-ion njengezinye izindlela ezingasetshenziswa esikhundleni samabhethri e-lithium-ion.Njengoba isidingo sezixazululo zokugcina amandla siqhubeka nokwanda, abacwaningi nabakhiqizi bahlola amandla amabhethri e-sodium-ion ukuhlangabezana nezidingo ezikhulayo zezimboni ezihlukahlukene, kuhlanganise nezimoto zikagesi, ukugcinwa kwamandla avuselelekayo kanye ne-electronics ephathekayo.Lokhu kuqubule impikiswano ngokuthi ingabe amabhethri e-sodium-ion aphakeme kunamabhethri e-lithium-ion.Kulesi sihloko, sizohlola umehluko obalulekile phakathi kwebhethri le-sodium-ion ne-lithium-ion, ubuhle nobubi balelo nalelo, kanye namandla amabhethri e-sodium-ion ukuze adlulele amabhethri e-lithium-ion.
Amabhethri e-sodium-ion, njengamabhethri e-lithium-ion, angamadivayisi wokugcina amandla aphinde ashajwe asebenzisa izinqubo ze-electrochemical ukugcina nokukhulula amandla.Umehluko omkhulu usezintweni ezisetshenziselwa ama-electrode nama-electrolyte.Amabhethri e-lithium-ion asebenzisa izinhlanganisela ze-lithium (njenge-lithium cobalt oxide noma i-lithium iron phosphate) njengama-electrode, kuyilapho amabhethri e-sodium-ion esebenzisa izinhlanganisela ze-sodium (njenge-sodium cobalt oxide noma i-sodium iron phosphate).Lo mehluko ezintweni zokusebenza unomthelela omkhulu ekusebenzeni kwebhethri nasezindlekweni.
Enye yezinzuzo eziyinhloko zamabhethri e-sodium-ion ukuthi i-sodium iningi kakhulu kune-lithium futhi ibiza kancane.I-sodium ingenye yezinto ezitholakala ngobuningi eMhlabeni futhi ishibhile ukuyikhipha nokuyicubungula uma iqhathaniswa ne-lithium.Lokhu nala nezindleko eziphansi kwenza amabhethri e-sodium-ion abe inketho ekhangayo yezinhlelo zokusebenza ezinkulu zokugcina amandla, lapho ukuphumelela kwezindleko kuyisici esibalulekile.Ngokuphambene, ukunikezwa okulinganiselwe kwe-lithium kanye nezindleko eziphezulu kuphakamisa ukukhathazeka mayelana nokusimama kwesikhathi eside nokufinyeleleka kwamabhethri e-lithium-ion, ikakhulukazi njengoba isidingo sokugcina amandla siqhubeka sikhula.
Enye inzuzo yamabhethri e-sodium-ion amandla awo okuqina kwamandla aphezulu.Ukuminyana kwamandla kubhekisela enanini lamandla elingagcinwa kubhethri levolumu noma isisindo esithile.Nakuba amabhethri e-lithium-ion ngokuvamile enikeze ukuminyana kwamandla aphezulu kunezinye izinhlobo zamabhethri ashajwa kabusha, intuthuko yakamuva kubuchwepheshe bebhethri ye-sodium-ion ibonise imiphumela ethembisayo ekuzuzeni amazinga okuminyana kwamandla aqhathaniswayo.Lokhu kuyintuthuko ebalulekile njengoba ukuminyana kwamandla kubaluleke kakhulu ekwandiseni ububanzi bezimoto ezisebenza ngogesi kanye nokwenza ngcono ukusebenza kwezinto zikagesi eziphathwayo.
Ngaphezu kwalokho, amabhethri e-sodium-ion abonisa ukuzinza okuhle kokushisa nezici zokuphepha.Amabhethri e-lithium-ion ayaziwa ukuthi athambekele ekubalekeni okushisayo nasezingozini zokuphepha, ikakhulukazi uma onakalisiwe noma echayeke emazingeni okushisa aphezulu.Uma kuqhathaniswa, amabhethri e-sodium-ion abonisa ukuzinza okungcono kokushisa kanye nengozi ephansi yokubaleka kokushisa, okuwenza abe ukukhetha okuphephile kwezinhlelo zokusebenza ezihlukahlukene.Lokhu kuphepha okuthuthukisiwe kubaluleke kakhulu ezimotweni zikagesi kanye nezinhlelo zokugcina amandla ezimile, lapho ubungozi bokusha kwebhethri nokuqhuma kufanele kuncishiswe.
Ngaphandle kwalezi zinzuzo, amabhethri e-sodium-ion nawo anemikhawulo ethile uma kuqhathaniswa namabhethri e-lithium-ion.Enye yezinselelo ezinkulu amandla kagesi aphansi namandla athile amabhethri e-sodium-ion.Amandla kagesi aphansi aphumela ekuphumeni kwamandla aphansi kuseli ngalinye, okuthinta ukusebenza kahle kanye nokusebenza kahle kwesistimu yebhethri.Ukwengeza, amabhethri e-sodium-ion ngokuvamile anamandla athile aphansi (amandla agcinwe ngeyunithi ngayinye yesisindo) kunamabhethri e-lithium-ion.Lokhu kungase kuthinte ukuminyana kwamandla kanye nokuba usizo kwamabhethri e-sodium-ion kwezinye izinhlelo zokusebenza.
Omunye umkhawulo wamabhethri e-sodium-ion impilo yawo yomjikelezo kanye nekhono lesilinganiso.Impilo yomjikelezo isho inombolo yokushaja nemijikelezo yokukhipha ibhethri elingadlula kuyo ngaphambi kokuba umthamo walo wehle kakhulu.Nakuba amabhethri e-lithium-ion aziwa ngokuphila kwawo komjikelezo omude uma kuqhathaniswa, amabhethri e-sodium-ion ngokomlando aye abonisa ukuphila komjikelezo ophansi kanye nokushajwa okuhamba kancane kanye namazinga okuphuma.Kodwa-ke, imizamo eqhubekayo yocwaningo nentuthuko igxile ekuthuthukiseni impilo yomjikelezo kanye namakhono okulinganisa amabhethri e-sodium-ion ukuze abenze bancintisane kakhulu namabhethri e-lithium-ion.
Womabili amabhethri e-sodium-ion kanye ne-lithium-ion anezinselelo zawo uma kuziwa kumthelela wemvelo.Nakuba i-sodium iningi kakhulu futhi ishibhile kune-lithium, ukukhishwa nokucubungula ama-sodium compounds kusengaba nemithelela yemvelo, ikakhulukazi ezindaweni lapho izinsiza ze-sodium zigxila khona.Ukwengeza, ukukhiqizwa nokulahlwa kwamabhethri e-sodium-ion kudinga ukucatshangelwa ngokucophelela kwemithetho yezemvelo kanye nezinqubo zokusimama ukuze kuncishiswe umthelela wawo emvelweni.
Uma uqhathanisa ukusebenza okuphelele nokufaneleka kwamabhethri e-sodium-ion kanye ne-lithium-ion, kubalulekile ukucabangela izidingo ezithile zezinhlelo zokusebenza ezahlukene.Isibonelo, ezinhlelweni ezinkulu zokugcina amandla, lapho ukuphumelela kwezindleko kanye nokusimama kwesikhathi eside kuyizici ezibalulekile, amabhethri e-sodium-ion angase anikeze isisombululo esikhangayo ngenxa yobuningi be-sodium kanye nezindleko eziphansi.Ngakolunye uhlangothi, amabhethri e-lithium-ion asengahlala encintisana ezinhlelweni ezidinga ukuminyana kwamandla aphezulu kanye nokushaja okusheshayo namazinga okukhipha, njengezimoto zikagesi nezinto zikagesi eziphathwayo.
Kafushane, impikiswano mayelana nokuthi amabhethri e-sodium-ion aphakeme kunamabhethri e-lithium-ion iyinkimbinkimbi futhi inezici eziningi.Nakuba amabhethri e-sodium-ion enikeza izinzuzo ngobuningi, izindleko, nokuphepha, aphinde abhekane nezinselele ekuminyana kwamandla, impilo yomjikelezo, namandla wesilinganiso.Njengoba ucwaningo nokuthuthukiswa kobuchwepheshe bebhethri kuqhubeka, amabhethri e-sodium-ion cishe azoncintisana kakhulu namabhethri e-lithium-ion, ikakhulukazi ezinhlelweni ezithile lapho izici zawo ezihlukile zifaneleka kahle.Ekugcineni, ukukhetha phakathi kwamabhethri e-sodium-ion kanye ne-lithium-ion kuzoncika ezidingweni ezithile zohlelo lokusebenza ngalunye, ukucatshangelwa kwezindleko nomthelela wemvelo, kanye nokuthuthuka okuqhubekayo kubuchwepheshe bebhethri.
