Ngokumelene nokwasemuva kokushintsha kwamandla omhlaba kanye nezinjongo "zekhabhoni ekabili", ubuchwepheshe bebhethri, njengesinikezeli esiyinhloko sokugcina amandla, buye bathola ukunakwa okukhulu. Eminyakeni yamuva nje, amabhethri e-sodium-ion (SIBs) aqhamuke emalabhorethri aye embonini, abe yisixazululo esilindelwe kakhulu sokugcina amandla kulandela amabhethri e-lithium-ion.
Ulwazi Oluyisisekelo mayelana namabhethri e-Sodium-ion
Amabhethri e-sodium-ion awuhlobo lwebhethri lesibili (elishajwa kabusha) elisebenzisa i-sodium ion (Na⁺) njengezithwali zokushaja. Isimiso sabo sokusebenza sifana nesamabhethri e-lithium-ion: ngesikhathi sokushaja nokukhipha, i-sodium ions shuttle phakathi kwe-cathode ne-anode nge-electrolyte, okuvumela ukugcinwa kwamandla nokukhululwa.
·Izinto Ezibalulekile: I-cathode ivamise ukusebenzisa ama-oxide anengqimba, izinhlanganisela ze-polyanionic, noma ama-analogue aluhlaza okwesibhakabhaka e-Prussian; i-anode ikakhulukazi yakhiwe ngekhabhoni eqinile noma ikhabhoni ethambile; i-electrolyte iyisisombululo sikasawoti we-sodium.
·Ukukhula Kwezobuchwepheshe: Ucwaningo lwaqala ngeminyaka yawo-1980s, futhi ukuthuthuka kwakamuva kwezinto zokwakha nezinqubo kuye kwathuthukisa kakhulu ukuminyana kwamandla kanye nempilo yomjikelezo, okwenza ukuhweba kwenzeke kwenzeke.
Amabhethri e-Sodium-ion vs. Amabhethri e-Lithium-ion: Umehluko Oyinhloko kanye Nezinzuzo
Nakuba amabhethri e-sodium-ion abelana ngesakhiwo esifanayo namabhethri e-lithium-ion, ahluke kakhulu ezintweni ezibonakalayo kanye nezimo zohlelo lokusebenza:
| Ubukhulu bokuqhathanisa | Amabhethri e-Sodium-ion | Amabhethri e-Lithium-ion |
| Ukuchichima Kwezinsiza | Isodium iyiningi (2.75% kuqweqwe lomhlaba) futhi isatshalaliswa kabanzi | I-Lithium iyindlala (0.0065%) futhi igxile ngokwendawo |
| Izindleko | Izindleko eziphansi zezinto ezingavuthiwe, uchungechunge lokuhlinzekwa kwempahla oluzinzile | Ukuguquguquka kwentengo ephezulu kwe-lithium, i-cobalt, nezinye izinto zokwakha, kuncike ekuthengeni kwamanye amazwe |
| Ukuminyana kwamandla | Ngaphansi (120-160 Wh/kg) | Phezulu (200-300 Wh/kg) |
| Ukusebenza Kwezinga Lokushisa Eliphansi | Ukugcinwa kwamandla >80% ku -20℃ | Ukusebenza okungalungile emazingeni okushisa aphansi, umthamo wehla kalula |
| Ukuphepha | Ukuzinza okuphezulu kokushisa, ukumelana kakhulu nokushajwa ngokweqile/ukukhishwa | Idinga ukuphathwa okuqinile kwezingozi ezishisayo zokubaleka |
Izinzuzo Eziyinhloko zamabhethri e-Sodium-ion:
1.Izindleko Eziphansi kanye Nokusimama Kwezinsiza: I-sodium itholakala kakhulu emanzini olwandle namaminerali, inciphisa ukuthembela ezinsimbi eziyivelakancane futhi yehlise izindleko zesikhathi eside ngo-30% -40%.
2. Ukuphepha Okuphezulu kanye Nobungani Bemvelo: Ikhululekile ekungcolisweni kwensimbi esindayo, ehambisana nezinhlelo eziphephile ze-electrolyte, futhi ifanele ukugcinwa kwamandla amakhulu.
3. Ukuguquguquka Kwebanga Lokushisa Okubanzi: Ukusebenza okuhle kakhulu ezindaweni ezinezinga lokushisa eliphansi, kulungele izifunda ezibandayo noma amasistimu okugcina amandla angaphandle.
Amathemba okusebenza kwamabhethri e-Sodium-ion
Ngokuthuthuka kwezobuchwepheshe, amabhethri e-sodium-ion akhombisa amandla amakhulu kulezi zindawo ezilandelayo:
1. Amasistimu Esitoreji Samandla Esilinganiso Esikhulu (ESS):
Njengesixazululo esihambisanayo samandla omoya namandla elanga, izindleko eziphansi zamabhethri e-sodium-ion nokuphila isikhathi eside kunganciphisa ngempumelelo izindleko ezilinganisiwe zikagesi (LCOE) futhi zisekele ukushefa okuphezulu kwegridi.
2. Izimoto zikagesi ezinesivinini esiphansi kanye namasondo amabili:
Ezimeni ezinezidingo eziphansi zokuminyana kwamandla (isb., amabhayisikili kagesi, izimoto zokuthutha), amabhethri e-sodium-ion angangena esikhundleni samabhethri e-lead-acid, anikeze kokubili izinzuzo zemvelo nezomnotho.
3. I-Base Station Energy Storage Eyisipele Amandla:
Ukusebenza kwazo kwebanga elibanzi lokushisa kuzenza zifanelekele izidingo zamandla eziyisipele ezinhlelweni ezizwela izinga lokushisa njengeziteshi eziyisisekelo zokuxhumana nezikhungo zedatha.
Amathrendi Okuthuthukisa Ikusasa
Izibikezelo zemboni zibikezela ukuthi imakethe yomhlaba wonke yamabhethri e-sodium-ion izodlula amaRandi ayizigidi eziyizinkulungwane ezinhlanu ngo-2025 futhi ifinyelele ku-10% -15% wemakethe yebhethri ye-lithium-ion ngo-2030. Izikhombisi-ndlela zentuthuko yesikhathi esizayo zihlanganisa:
·I-Material Innovation: Ukuthuthukisa ama-cathodes omthamo omkhulu (isb, ama-oxide engqimba ohlobo lwe-O3) kanye nezinto ze-anode yempilo ende ukuze kukhuliswe ukuminyana kwamandla ngaphezu kuka-200 Wh/kg.
·Ukuthuthukisa Inqubo: Ukusebenzisa imigqa yokukhiqiza ibhethri ye-lithium-ion evuthiwe ukuze kukhuliswe ukukhiqizwa kwebhethri ye-sodium-ion futhi kunciphise izindleko.
·Ukunwetshwa kohlelo lokusebenza: Ukugcwalisa amabhethri e-lithium-ion ukwakha iphothifoliyo yobuchwepheshe bokugcina amandla ahlukahlukene.
Isiphetho
Ukukhuphuka kwamabhethri e-sodium-ion akuhloselwe ukufaka esikhundleni amabhethri e-lithium-ion kodwa ukunikeza enye indlela eyongayo nephephile yokugcina amandla. Ngomongo wokungathathi hlangothi kwekhabhoni, imvelo yabo yokusebenziseka kalula kanye nokuguquguquka kwesicelo izovikela indawo yabo endaweni yokugcina amandla. Njengengqalabutho ekusungulweni kobuchwepheshe bamandla,DALYizoqhubeka nokuqapha ukuthuthukiswa kobuchwepheshe bebhethri ye-sodium-ion, izibophezele ekuletheni izixazululo zamandla ezisebenza kahle nezisimeme kumakhasimende ethu.
Silandele ukuze uthole izibuyekezo zobuchwepheshe ezisezingeni eliphezulu!
