Vaongorori vekuChalmers University of Technology vakurudzira nzira itsva uye inoshanda yekudzokorora simbi kubva kumabhatiri emotokari dzemagetsi. Nzira iyi inotora 100% aruminiyamu uye 98% lithium kubva kumabhatiri eEV akamboshandiswa. Izvi zvinoderedza kurasikirwa nezvinhu zvakakosha zvakaita senickel, cobalt uye manganese. Maitiro aya haadi makemikari anodhura kana ane njodzi nekuti vaongorori vakashandisa oxalic acid, acid inowanikwawo muhushe hwezvirimwa.
Kusvika pari zvino, hapana akakwanisa kuwana mamiriro akakodzera ekuparadzanisa huwandu uhu hwe lithium uchishandisa oxalic acid nekubvisa aruminiyamu yese. Leah Rouquette, mudzidzi wePhD muDhipatimendi reChemistry and Chemical Engineering paChalmers University of Technology, akati sezvo mabhatiri ese aine aruminiyamu, tinofanira kukwanisa kuibvisa tisingarasikirwe nedzimwe simbi.
PaBattery Recycling Laboratory paChalmers University of Technology, Leah Rouquette nemutungamiri wetsvagiridzo Martina Petranikova vakaratidza mashandiro anoita nzira itsva iyi. Rabhoritari iyi yaive nemabhatiri emota dzakamboshandiswa, uye mufuro maive nezvinhu zvakapwanywa zvakaita seupfu hwakakuyiwa hwakanyungudutswa mumvura yakachena - oxalic acid. Leah Rouquette anoshandisa chinotaridzika semuchina wekubikisa kicheni kusanganisa zvinwiwa nehupfu. Kunyangwe zvichitaridzika zviri nyore sekunge ari kugadzira kofi, nzira yacho yakasiyana uye ichangobva kuburitswa nesainzi. Nekugadzirisa tembiricha, kutarisisa uye nguva, vaongorori vakagadzira nzira itsva inoshandisa oxalic acid, chinhu chisina njodzi kunharaunda chinowanikwawo mumiti yakaita serhubarb nesipinachi.
Zvimwe zvinoshandiswa panzvimbo pemakemikari asina kugadzirwa nemakemikari aripo nhasi zvinodikanwa. Pamusoro pezvo, chimwe chezvipingamupinyi zvikuru mumabasa emazuva ano kubviswa kwezvinhu zvakasara zvakaita searuminiyamu. Martina Petranikova, Mubatsiri wePurofesa muDhipatimendi reChemistry neChemical Engineering paChalmers University of Technology, akati inzira itsva inogona kupa dzimwe nzira itsva dzekushandisa pakugadzira zvinhu zvakareruka uye kubatsira kugadzirisa matambudziko ari kudzosera zvinhu kumashure.
Nzira dzekugadzirisa dzinoshandiswa mumvura dzinonzi hydrometallurgy. Mu hydrometallurgy yechinyakare, "tsvina" inobva muzvinhu zvakaita searuminiyamu nemhangura inotanga yabviswa, uye simbi dzinokosha dzakadai se lithium, cobalt, nickel uye manganese dzinogona kushandiswa. Kunyangwe paine simbi diki chete yearuminiyamu nemhangura, matanho akati wandei ekuchenesa anodiwa, uye danho rega rega rekuita izvi rinoburitsa mvura. Munzira itsva, vaongorori vakachinja kucheka uye kutanga vakaparadzanisa lithium nearuminiyamu. Nenzira iyi, vanogona kuderedza kusara kwesimbi dzinokosha dzinodiwa kugadzira mabhatiri matsva.
Kunyangwe chikamu chechipiri chemaitiro aya—kusefa musanganiswa wakasviba—kunoyeuchidza nezvekubika kofi. Kunyange zvazvo aruminiyamu nelithium zvichipinda mumvura, dzimwe simbi dzinoramba dziri mu "sump." Danho rinotevera mukuita uku nderekuparadzanisa aruminiyamu nelithium.
"Nekuti simbi idzi dzine hunhu hwakasiyana kwazvo, tinotenda kuti kudziparadzanisa hakuzove kwakaoma. Nzira yedu itsva inovhura nzira itsva inovimbisa yekudzokorodza mabhatiri yatine chikonzero chekutsvaga zvakawanda," anodaro Leah Rouquette. "Sezvo nzira iyi ichigonawo kushandiswa zvakanyanya, tinotarisira kuti ichave inobatsira mumaindasitiri mumakore anotevera," anodaro Martina Petranikova.
Boka rekutsvagisa raMartina Petranikova rave richiita tsvakurudzo huru pamusoro pekudzokorodza simbi mumabhatiri e lithium-ion kwemakore mazhinji. Boka iri rinoshanda pamwe chete nemakambani ane chekuita nekudzokorodza mabhatiri emotokari dzemagetsi uye ishamwari muzvirongwa zvikuru zveR&D zvakaita seVolvo Cars neprojekti yeNybat yeNorthvolt.
Mamwe mashoko nezvekutsvaga: Nyaya yesainzi inoti “Kudzoreredza zvizere lithium kubva kumabhatiri emagetsi e lithium-ion: kutevedzera nekugadzirisa uchishandisa oxalic acid se lixiviant” yakaburitswa mujenari reSeparation and Purification Technology. Chidzidzo ichi chakaitwa naLeah Rouquette, Martina Petranikova naNatalia Vieceli vanobva kuDhipatimendi reChemistry and Chemical Engineering paChalmers University of Technology. Tsvagiridzo iyi yakatsigirwa nemari neSwedish Energy Agency, Swedish Battery Base naVinnova, uye kuyedza uku kwakaitwa uchishandisa mabhatiri emagetsi eVolvo Cars akamboshandiswa akagadziriswa neStena Recycling naAkkuser Oy.
Tinoburitsa zvinyorwa zvakawanda kubva kunyanzvi dzeminda yakasiyana-siyana. Iyi ndiyo nhoroondo yedu yevanhu vakakosha ava, masangano, masangano nemakambani.
