Abacwaningi baseStanford University benza intuthuko enkulu ekwakheni ubuchwepheshe obusha bokukhipha i-lithium emanzini anosawoti. Amakheli endlela esebenza kahle futhi eco-friendlyizinkinga zokuhlushwa kwe-lithiumekukhishweni nasekucutshungulweni kwendabuko. Ubuchwepheshe buyathuthukaukuhlushwa kwe-lithium brineicutshungulwe futhi ikwenze kusheshe, kushibhile futhi kusimeme imvelo nge-redox-couple electrolysis (RCE). Ubuchwepheshe obusha bunciphisa izindleko ngama-40% kunendlela ebusayo yokukhipha.
Ngokukhuphuka kwezimoto zikagesi kanye nokugcinwa kwamandla avuselelekayo, isidingo sikazwelonke se-lithium sikhule emashumini eminyaka amuva nje.Ukugxila kwe-lithium oreidinga ukufinyelela ezingeni elithile, bese ingasetshenziswa ibe ibhethri lithium. Isizinda esiningi se-lithium sincika ekuhwamukeni kwamanzi ashisayo emachibini amakhulu ngaphansi kwelanga unyaka noma ngaphezulu, kushiye isixazululo esicebile se-lithium.
Njengamanje, i-lithium idlala indima ebalulekile ekuthuthukisweni kwamandla omhlaba kumandla aqhubekayo. Kulinganiselwa ukuthi isidingo se-lithium sizokhuphuka sisuka ku-0.5 million metric tons ngo-2021 siye ku-4 million metric tons ngo-2030. Ukwanda okubukhali kubangelwa ukuthandwa nokusabalala okubanzi kwezimoto zikagesi nezinhlelo zamandla ahlanzekile.
Ngokuvamile, i-lithium ikhona ku-brine, emanzini olwandle namafutha angcolile, ngakho-keukulinganisa kokuhlushwa kwe-lithiumibalulekile ekukhishweni kwayo, ekutholeni ukufundwa okunembayo kwayoukuhlushwa kwe-lithium ku-brine, ukuhlushwa kwe-lithium emanzini olwandle, ukuhlushwa kwe-lithium emafutheni angcolile, ukuhlushwa kwe-lithium ku-oyela field brines.
I-lithium yendabuko ikhishwa emadwaleni ambiwe, ebiza kakhulu, edla amandla futhi eqhutshwa amakhemikhali anobuthi kunokukhishwa kwe-brine. Kulezi zinsuku, isizinda se-lithium sishintshele ekubeni amanzi anosawoti echibini ahwamukayo ngezindleko eziphansi kanye nezindleko eziphakeme zezimali kanye nezindleko zemvelo. Izimo zezulu ziyizici ezibalulekile ezithonya ukusebenza kahle kokukhiqiza, okwenza kube nokungabaza ikhono lemboni ye-lithium ukuhlangabezana nesidingo esikhulayo.
Izindleko Nezinzuzo Zemvelo
Ubuchwepheshe obusha bubiza kakhulu ngenxa yezindleko zemali ephansi zokwakha kanye nokugcina amachibi amakhulu okuhwamuka kwelanga. Ngaphezu kwalokho, ukusetshenziswa kukagesi, amanzi kanye nama-ejenti amakhemikhali kuncane kakhulu kunalokho kwezindlela ezimbili zangaphambilini. Ngokugwema ukusetshenziswa okubanzi komhlaba kanye nokusetshenziswa kwamanzi kwezindlela zendabuko, indlela ye-RCE iphinde yehlise indawo yemvelo yokukhiqizwa kwe-lithium.
Ngibheke Phambili
Ukukhula kwendlela ye-REC kuyathembisa nakuthrendi yesikhathi esizayo yezinsiza ezivuselelekayo. Ukukhishwa kwe-lithium okuzenzakalelayo nokuhlakaniphile kuwumkhuba ongenakuhlehliswa, ikakhulukazi kuwo wonke umugqa wokukhiqiza ohlanganisayoamamitha wokuminyana emgqeni, izinzwa zezinga ngisho nama-viscometers. Oxhumana nayeI-Lonnmeterukuze uthole izixazululo ezithuthukisiwe zokukhipha i-lithium brine. Ungathola iziphakamiso zochwepheshe konjiniyela bethu. Ungangabazi ukucela isaphulelo samahhala manje!
