Izinkampani zamandla zaseMelika zithola izakhi zomhlaba ezingavamile kumabhethri e-lithium ion alahlwayo!

Igayidi: Izinkampani zezinsiza zase-US zenza inqubo, yokuhlukanisa insimbi emsulwa yomhlaba engavamile ezimotweni zikagesi noma amabhethri e-lithium-ion asekelwe ezitshalweni zamandla avuselelekayo. Le nqubo ichazwa njenge-two-zone ligand auxiliary replacement chromatography (LAD), engaba nesivuno esikhulu nensimbi ibe ngaphezu kuka-99%. Ikomkhulu layo lihlala e-US Abahlinzeki bempahla yokusetshenziswa Izinkampani zezinsiza zase-US zakha indlela yokuthola izinsimbi ezilungile njengokutholwa kwe-neodymium (ND), 镨 (PR) kanye ne-镝 (DY) ngemva komjikelezo wempilo wamabhethri e-lithium ion.

Iphepha elishicilelwe yi-American Chemistry Society libonisa ukuthi abacwaningi baseNyuvesi yasePurdue, e-Indiana bakhipha kanjani ikhabhoni ehlanzekile emfucumfucwini wepulasitiki, bese beyenza ibe i-anode yebhethri ye-lithium-ion. Ibhethri iwumthombo wamandla weloli lokudlala. Ithimba lithi le ndlela inganwetshwa kalula.

Ngaphezu kwalokho, ukuthuthukiswa kwezimoto zikagesi nakho kungakha imakethe enkulu yale nto ye-anode. Amasu enkampani anelungelo lobunikazi atholwe eNyuvesi yasePurdue ngoFebhuwari, okuhlanganisa insimbi yomhlaba eyivelakancane kanye nezinto ezibalulekile ezivela emikhiqizweni yamalahle, kutholwe omagnethi baphakade nezimoto zikagesi noma amabhethri e-lithium-ion asetshenziswa ezitshalweni zamandla avuselelekayo. Inqubo.

Le nqubo ichazwa njenge-two-zone ligand auxiliary replacement chromatography (LAD), engaba nesivuno esikhulu nensimbi ibe ngaphezu kuka-99%. I-Chromatography yokubuyisela iyindlela yokulungiselela, ngokuvamile esetshenziselwa ukubeka isampula ku-stroke, bese ibuyisela esikhundleni nge-solute. Lolu hlelo lusekelwe endleleni yokuhlukanisa i-partition shunting, futhi kuthiwa umthamo wayo wokukhiqiza uwonke ungadlula i-100 kg yezinto ezingavamile zomhlaba ngosuku nge-cubic meter ngayinye.

Ifuna amakholomu amathathu, i-extractant, i-ethylenediamine tetracetic acid (EDTA) namanye amakhemikhali angachazwanga ahambisana nemvelo. Kuthiwa i-LAD ayinayo imiphumela emibi emvelweni kunendlela yendabuko esekelwe kwi-asidi isebenzisa inqubo yokukhipha uketshezi oluwuketshezi lwezigaba ezimbili. Abacwaningi bathi ngakolunye uhlangothi, ngenxa yezinga eliphezulu lamakhemikhali nezakhiwo ezingokomzimba zezinsimbi zomhlaba ezingavamile, kuphinde kube nobunzima ekuhlukaniseni izinsimbi zomhlaba ezingavamile.

Isikhulu esiphezulu se-US Resources uMark Jensen uthe: “Sekukonke, ubuchwepheshe bethu kanye neketanga lezinqubo ezingavuthiwe kusenza sikwazi ukusiza ukubuyisela lezi zinsiza ezibalulekile ngendlela esimeme futhi enobungani bemvelo ukusiza ukubuyisela lezi zinto ezibalulekile. Ithimba leNyuvesi yasePurdue liyingxenye ebalulekile, sibheke phambili ekukhuthazeni ubuchwepheshe ngenkuthalo, sibonisa ubuchwepheshe obungabizi kakhulu futhi obubucayi bemvelo. “Ngaso leso sikhathi, abanye ososayensi eNyuvesi yasePurdue basungule inqubo ekhipha ikhabhoni emsulwa emfucumfucwini wepulasitiki, bese iyiguqula ibe yi-anode yebhethri ye-lithium-ion.
