Hamwe niterambere ryihuse ryinganda nshya zingufu, isabwa rya bateri ya lithium ikora cyane iriyongera. Nubwo ibikoresho nka lithium fer fosifate (LFP) na lithium ya ternary bifite umwanya wiganje, umwanya wabo wo kongera ingufu zingana ni muto, kandi umutekano wabo uracyakeneye kurushaho kunozwa. Vuba aha, ibice bya zirconium, cyane cyane zirconium tetrachloride (ZrCl₄) n'ibiyikomokaho, byahindutse buhoro buhoro ubushakashatsi bitewe nubushobozi bwabo mukuzamura ubuzima bwinzira n'umutekano bya bateri ya lithium.
Ibishoboka nibyiza bya zirconium tetrachloride
Ikoreshwa rya zirconium tetrachloride n'ibiyikomokaho muri bateri ya lithium bigaragarira cyane cyane mubice bikurikira:
1.Gutezimbere uburyo bwo kohereza ion:Ubushakashatsi bwerekanye ko ibyuma kama kama (MOF) byongeweho hamwe na Zr⁴⁺ zidahuza neza bishobora kuzamura imikorere yimikorere ya lithium ion. Imikoranire ikomeye hagati yimbuga za Zr⁴⁺ na lithium ion yo gukiza irashobora kwihutisha kwimuka kwa ioni ya lithium, bityo bikazamura imikorere yikigereranyo nubuzima bwa cycle ya bateri.
2.Iterambere ryimbere ryimbere:inkomoko ya zirconium tetrachloride irashobora guhindura imiterere yo gukiza, kuzamura intera ihagaze hagati ya electrode na electrolyte, kandi bikagabanya kugaragara kwimyitwarire kuruhande, bityo bikazamura umutekano nubuzima bwa bateri.
Impirimbanyi hagati yikiguzi nigikorwa: Ugereranije nibikoresho bimwe na bimwe bihenze cyane bya electrolyte, igiciro fatizo cya zirconium tetrachloride nibiyikomokaho ni bike. Kurugero, ikiguzi cyibikoresho bya electrolytite ikomeye nka lithium zirconium oxychloride (Li1.75ZrCl4.75O0.5) ni $ 11,6 / kg gusa, bikaba biri munsi cyane ya electrolytite gakondo.
Ugereranije na lithium fer fosifate na lithium ternary
Litiyumu ya fosifate (LFP) na lithium ya ternary ni ibikoresho nyamukuru bya bateri ya lithium kuri ubu, ariko buriwese afite ibyiza bye nibibi. Lisiyumu y'icyuma ya fosifeti izwiho umutekano muke n'ubuzima burebure, ariko ingufu zayo ni nke; ternary lithium ifite ingufu nyinshi, ariko umutekano wacyo urakomeye. Ibinyuranye, zirconium tetrachloride n'ibiyikomokaho bikora neza mugutezimbere uburyo bwo kwimura ion no guhuza imiterere, kandi biteganijwe ko bizuzuza amakosa yibikoresho bihari.
Ibicuruzwa byubucuruzi nibibazo
Nubwo zirconium tetrachloride yerekanye imbaraga nyinshi mubushakashatsi bwa laboratoire, ubucuruzi bwayo buracyafite imbogamizi:
1.Ibikorwa bikuze:Kugeza ubu, uburyo bwo gukora zirconium tetrachloride n’ibiyikomokaho ntiburakura neza, kandi ihame n’ubudahangarwa by’umusaruro munini biracyakenewe kugenzurwa.
Kugenzura ibiciro:Nubwo igiciro cyibikoresho fatizo ari gito, mubikorwa nyabyo, hagomba gutekerezwa ibintu byigiciro nkibikorwa bya synthesis hamwe nishoramari ryibikoresho.
Kwemera isoko: Litiyumu ya fosifate na ternary lithium imaze gufata umugabane munini ku isoko. Nkibintu bigaragara, zirconium tetrachloride ikeneye kwerekana ibyiza bihagije mumikorere nigiciro kugirango imenyekane ku isoko.
Ibizaza
Zirconium tetrachloride n'ibiyikomokaho bifite amahirwe menshi yo gukoresha muri bateri ya lithium. Hamwe niterambere ryiterambere ryikoranabuhanga, gahunda yumusaruro iteganijwe kurushaho kunozwa kandi igiciro kizagabanuka buhoro buhoro. Mu bihe biri imbere, zirconium tetrachloride biteganijwe ko yuzuza ibikoresho nka lithium fer fosifate na lithium ternary, ndetse ikagera no gusimbuza igice mubice bimwe na bimwe byakoreshwa.

Nigute ZrCl₄ itezimbere imikorere yumutekano muri bateri?
1. Kubuza gukura kwa lithium dendrite
Gukura kwa lithium dendrite nimwe mumpamvu zingenzi zumuzunguruko mugufi hamwe nubushyuhe bwumuriro wa bateri ya lithium. Zirconium tetrachloride n'ibiyikomokaho birashobora kubuza imiterere no gukura kwa dendrite ya lithium muguhindura imiterere ya electrolyte. Kurugero, inyongeramusaruro ZrCl₄ zimwe zishobora gukora intera ihamye kugirango irinde lithium dendrite kwinjira muri electrolyte, bityo bigabanye ibyago byumuzunguruko mugufi.
2. Kuzamura ubushyuhe bwumuriro wa electrolyte
Gakondo ya electrolytite isanzwe ikunda kubora mubushyuhe bwinshi, ikarekura ubushyuhe, hanyuma igatera ubushyuhe bwumuriro.Zirconium tetrachloriden'ibiyikomokaho birashobora gukorana nibigize muri electrolyte kugirango bitezimbere ubushyuhe bwumuriro wa electrolyte. Iterambere rya electrolyte riragoye kubora kubushyuhe bwinshi, bityo bikagabanya ingaruka z'umutekano wa bateri mugihe cy'ubushyuhe bwinshi.
3. Kunoza imiterere yimbere
Zirconium tetrachloride irashobora kunoza intera ihagaze hagati ya electrode na electrolyte. Mugukora firime ikingira hejuru ya electrode, irashobora kugabanya ingaruka zuruhande rwibikoresho bya electrode na electrolyte, bityo bikazamura muri rusange bateri. Isohora ryimikorere ningirakamaro kugirango wirinde kwangirika kwimikorere nibibazo byumutekano bya bateri mugihe cyo kwishyuza no gusohora.
4. Kugabanya umuriro wa electrolyte
Imashanyarazi gakondo ya electrolytite muri rusange irashya cyane, ibyo bikaba byongera ibyago byumuriro wa batiri mugihe gikwiye. Zirconium tetrachloride n'ibiyikomokaho birashobora gukoreshwa mugutezimbere amashanyarazi akomeye cyangwa igice cya elegitoroniki ikomeye. Ibikoresho bya electrolyte mubusanzwe bifite umuriro mwinshi, bityo bikagabanya cyane ibyago byumuriro wa batiri no guturika.
5. Kunoza ubushobozi bwo gucunga amashyuza ya bateri
Zirconium tetrachloride n'ibiyikomokaho birashobora kuzamura ubushobozi bwo gucunga amashyuza ya bateri. Mugutezimbere ubushyuhe bwumuriro hamwe nubushyuhe bwumuriro wa electrolyte, bateri irashobora gukwirakwiza ubushyuhe neza mugihe ikorera mumitwaro myinshi, bityo bikagabanya amahirwe yo guhunga ubushyuhe.
6. Irinde guhunga ubushyuhe bwibikoresho byiza bya electrode
Rimwe na rimwe, guhunga ubushyuhe bwibikoresho byiza bya electrode nimwe mubintu byingenzi biganisha kubibazo byumutekano wa batiri. Zirconium tetrachloride n'ibiyikomokaho birashobora kugabanya ibyago byo guhunga ubushyuhe muguhindura imiti ya electrolyte no kugabanya kwangirika kwibintu byiza bya electrode nziza mubushyuhe bwinshi.
