Ngokuthuthuka okusheshayo kwemboni entsha yamandla, isidingo samabhethri e-lithium asebenza kahle siyakhula. Nakuba izinto ezifana ne-lithium iron phosphate (LFP) kanye ne-ternary lithium zithatha isikhundla esivelele, indawo yazo yokuthuthukisa ukuminyana kwamandla sinomkhawulo, futhi ukuphepha kwazo kusadinga ukuthuthukiswa okwengeziwe. Muva nje, ama-zirconium-based compounds, ikakhulukazi i-zirconium tetrachloride (ZrCl₄) kanye nokuphuma kwayo, kancane kancane sekuyisizinda socwaningo ngenxa yamandla azo okuthuthukisa impilo yomjikelezo nokuphepha kwamabhethri e-lithium.
Amandla kanye nezinzuzo ze-zirconium tetrachloride
Ukusetshenziswa kwe-zirconium tetrachloride kanye nokuphuma kwayo kumabhethri e-lithium kubonakala kakhulu kulezi zici ezilandelayo:
1.Ukuthuthukisa ukusebenza kahle kokudlulisa i-ion:Ucwaningo lubonise ukuthi izithasiselo ze-metal organic framework (MOF) ezinamasayithi e-Zr⁴⁺ angathuthukisa kakhulu ukusebenza kahle kokudluliselwa kwama-ion e-lithium. Ukusebenzisana okuqinile phakathi kwamasayithi e-Zr⁴⁺ kanye neshethi ye-lithium ion solvation kungasheshisa ukuthuthela kwe-lithium ion, ngaleyo ndlela kuthuthukise ukusebenza kwezinga kanye nempilo yomjikelezo webhethri.

Ibhalansi phakathi kwezindleko nokusebenza: Uma kuqhathaniswa nezinye izinto eziqinile ze-electrolyte ezibiza kakhulu, izindleko zezinto ezingavuthiwe ze-zirconium tetrachloride kanye nokuphuma kwayo ziphansi kakhulu. Isibonelo, izindleko zempahla yokusetshenziswa yama-electrolyte aqinile njenge-lithium zirconium oxychloride (Li1.75ZrCl4.75O0.5) yi-$11.6/kg kuphela, ephansi kakhulu kunama-electrolyte aqinile endabuko.
Ukuqhathanisa ne-lithium iron phosphate kanye ne-ternary lithium
I-Lithium iron phosphate (LFP) kanye ne-ternary lithium yizinto ezisetshenziswayo zamabhethri e-lithium njengamanje, kodwa ngayinye inezinzuzo zayo kanye nokubi. I-lithium iron phosphate yaziwa ngokuphepha kwayo okuphezulu nokuphila komjikelezo omude, kodwa amandla ayo aphansi aphansi; I-ternary lithium inomthamo omkhulu wamandla, kodwa ukuphepha kwayo kubuthakathaka. Ngokuphambene nalokho, i-zirconium tetrachloride kanye nokuphuma kwayo kusebenza kahle ekuthuthukiseni ukusebenza kahle kokudluliselwa kwe-ion kanye nokuzinza kwesixhumi esibonakalayo, futhi kulindeleke ukuthi yenze ukushiyeka kwezinto ezikhona.
Izingqinamba nezinselelo zokuhweba
Nakuba i-zirconium tetrachloride ibonise amandla amakhulu ocwaningweni lwaselabhorethri, ukuthengiswa kwayo kusabhekene nezinselelo ezithile:
1.Inqubo yokuvuthwa:Njengamanje, inqubo yokukhiqiza i-zirconium tetrachloride kanye nokuphuma kwayo ayikavuthwa ngokugcwele, futhi ukuzinza nokuvumelana kokukhiqizwa okukhulu kusadinga ukuqinisekiswa okwengeziwe.
2.Ukulawula izindleko:Nakuba izindleko zezinto zokusetshenziswa ziphansi, ekukhiqizeni kwangempela, izici zezindleko ezifana nenqubo yokuhlanganiswa kanye nokutshalwa kwezimali kwemishini kudingeka kucatshangelwe.
Ukwamukelwa kwemakethe: I-lithium iron phosphate kanye ne-ternary lithium sezivele zinesabelo esikhulu semakethe. Njengempahla evelayo, i-zirconium tetrachloride idinga ukukhombisa izinzuzo ezanele ekusebenzeni nasezindlekweni ukuze uthole ukuqashelwa kwemakethe.
Ikusasa Outlook
I-Zirconium tetrachloride kanye nokuphuma kwayo kunamathemba abanzi okusebenza kumabhethri e-lithium. Ngokuthuthuka okuqhubekayo kobuchwepheshe, inqubo yayo yokukhiqiza kulindeleke ukuthi ithuthukiswe futhi izindleko zizokwehla kancane kancane. Ngokuzayo, i-zirconium tetrachloride kulindeleke ukuthi igcwalise izinto ezifana ne-lithium iron phosphate kanye ne-ternary lithium, futhi izuze nokufaka esikhundleni ngokwengxenye kuzimo ezithile zohlelo lokusebenza.
