3.3. Electrolytic electrolytic mokhoa hlaphoheloa valvily tšepe ka litšila lithium ion betri, ke mokhoa oa lik&39;hemik&39;hale electrolysis ka eleketrode lintho tse bonahalang leaching mokelikeli, e le hore e fokotsehile ho e le &39;ngoe kapa sediment.

U se ke ua eketsa lintho tse ling, ha ho bonolo ho hlahisa litšila, li ka fumana lihlahisoa tse phahameng tsa bohloeki, empa tabeng ea li-ion tse ngata, ho na le deposition e feletseng, kahoo e fokotsa bohloeki ba sehlahisoa, ha e ntse e sebelisa matla a mangata a motlakase. Myoung et al. Matlakala a lithium ion battery positive material leaching liquid bakeng sa phekolo ea HNO3 ke thepa e tala, &39;me cobalt e fumanoa ka mokhoa o sa khaotseng o ka khonehang.

Nakong ea ts&39;ebetso ea electrolysis, O2 e fokotsehile ho NO3 - karabelo ea ho fokotsa, OH-concentration e eketsoa, ​​​​&39;me CO (OH) 2 e hlahisoa holim&39;a Ti cathode, &39;me phekolo ea mocheso e fumanoa ke CO3O4. Mokhoa oa ho itšoara ka lik&39;hemik&39;hale o tjena: 2H2O + O2 + 4E→4OHNO3- + H2O + 2E→NO2- + 2OHCO3 ++ E→CO2 + CO2 ++ 2OH- / TI→CO (OH) 2 / Ti3CO (OH) 2 / Ti + 1 / 2O2→CO3O4 / TI + 3H2OFREITAS, joalo-joalo, ho sebelisa bokhoni bo sa feleng le theknoloji e matla ea ho khutlisa CO ho tloha linthong tse ntle tsa betri ea lithium ion.

Liphetho li bonts&39;a hore ts&39;ebetso ea tefiso ea CO e ea fokotseha ha pH e ntse e eketseha, pH = 5.40, bokhoni -1.00V, tefiso ea 10.

4, mokhoa oa phapanyetsano ea ion mokhoa oa phapanyetsano ea ion ke phapang ea bokhoni ba adsorption ea mefuta e fapaneng ea li-ion tsa tšepe tse kang Co, Ni, ho hlokomela karohano le ho ntšoa ha tšepe. FENG le ba bang. Ho eketsa ho hlaphoheloa ha CO ho tsoa ho lisebelisoa tse ntle tsa electrode H2SO4 leaching liquid.

Ithute ka sekhahla sa ho hlaphoheloa ha cobalt le karohano ea litšila tse ling ho tsoa linthong tse kang pH, potoloho ea leach. Liphello li bontšitse hore resin ea TP207 e ne e sebelisetsoa ho laola pH = 2.5, ho potoloha ho ne ho phekoloa 10.

Sekhahla sa ho tlosoa ha Cu se fihlile 97.44%, &39;me ho hlaphoheloa ha cobalt ho fihlile 90,2%.

Mokhoa o na le khetho e matla ea ion e lebisitsoeng, mokhoa o bonolo le o bonolo oa ho sebetsa, o ntšoa bakeng sa ho ntšoa ha theko ea tšepe e feto-fetohang ka har&39;a betri ea lithium ion, e faneng ka litsela tse ncha, empa ka lebaka la moeli o phahameng oa litšenyehelo, kopo ea indasteri. 3.5, saltingation ea salinization ke ho fokotsa dielectric constant of the leaching liquid ka ho eketsa saturated (NH4) 2SO4 tharollo le tlaase dielectric kamehla solvent ka litšila lithium ion battery leaching solution, ka tsela eo ho fokotsa dielectric constant of the leaching liquid, le cobalt letsoai le precipitated ho tloha tharollo.

Mokhoa o bonolo, o bonolo ho sebetsa le o tlaase, empa tlas&39;a maemo a mefuta e sa tšoaneng ea li-ion tsa tšepe, ka pula ea matsoai a mang a tšepe, ka hona ho fokotsa bohloeki ba sehlahisoa. Jin Yujian et al, ho ea ka khopolo ea morao-rao ea tharollo ea electrolyte, tšebeliso ea libeteri tsa lithium ion tse nang le letsoai. A saturated (NH4) 2SO4 aqueous solution le anhydrous ethanol li ile tsa kenngoa ho tloha ho HCl leaching liquid ho tloha LiiCoO2 e le electrode e ntle, &39;me ha tharollo, e tletse (NH4) 2SO4 tharollo ea metsi le anhydrous ethanol e ne e le 2: 1: 3, CO2 + sekhahla sa pula Ho feta 92%.

Sehlahisoa sa letsoai se hlahisoang ke (NH4) 2CO (SO4) 2 le (NH4) Al (SO4) 2, e sebelisang letsoai le arohaneng ho arola letsoai le le leng, kahoo ho fumana lihlahisoa tse fapaneng. Mabapi le ho ntšoa le ho arohana ha tšepe ea bohlokoa ka har&39;a litšila tsa lithium ion battery leach, tse ka holimo ke litsela tse &39;maloa tsa ho ithuta ho eketsehileng. Ho nahanoa ka lintlha tse kang ho sebetsa ha molumo, litšenyehelo tsa ts&39;ebetso, bohloeki ba sehlahisoa le tšilafalo ea bobeli, Letlapa la 2 le akaretsa mokhoa oa botekgeniki oa ho bapisa lisebelisoa tse &39;maloa tsa karohano ea tšepe tse hlalositsoeng ka holimo.

Hona joale, tšebeliso ea libeteri tsa lithium-ion ka matla a motlakase le likarolo tse ling li pharalletse haholo, &39;me palo ea libeteri tsa lithium-ion e ke keng ea fokotsoa. Mothating ona, ts&39;ebetso ea ho khutlisa betri ea lithium-ion e sa senyeheng e bohlokoa bakeng sa kalafo ea pele - ho hlatsuoa ka metsi. Phekolo ea pele e kenyelletsa ho lahla, ho senya le karohano ea lisebelisoa tsa electrode, joalo-joalo.

Har&39;a bona, mokhoa oa ho qhala o bonolo, &39;me o ka ntlafatsa ka katleho phello ea karohano le sekhahla sa ho hlaphoheloa, empa sesebelisoa sa bohlokoa se sebelisoang hona joale (NMP) se theko e boima ho isa tekanyong e itseng, e le hore ho sebelisoa ha solvent e loketseng ho feta ho etsa lipatlisiso tšimong ena. E &39;ngoe ea litsela. Ts&39;ebetso ea leaching ke ea bohlokoa ka moemeli oa ho fokotsa acid e le moemeli oa leaching, e ka finyellang phello e khethiloeng ea leaching, empa ho tla ba le tšilafalo ea bobeli e kang mokelikeli oa litšila tse sa tloaelehang, &39;me mokhoa oa leaching oa likokoana-hloko o na le monyetla oa ho sebetsa hantle, ho sireletsa tikoloho le theko e tlaase, empa ho na le tšepe ea bohlokoa.

Sekhahla sa leaching se batla se phahame, &39;me ho ntlafatsa khetho ea libaktheria le ho ntlafatsa maemo a leaching ho ka eketsa sekhahla sa leaching, e leng e&39; ngoe ea litsela tsa lipatlisiso tsa ts&39;ebetso ea nako e tlang. Litšepe tsa Valentine ho litharollo tsa leaching tse nang le metsi ke lihokela tsa bohlokoa tsa ts&39;ebetso ea ho hlaphoheloa ha betri ea lithium-ion, le lintlha tsa bohlokoa le mathata a lipatlisiso lilemong tsa morao tjena, &39;me mekhoa ea bohlokoa e na le ho ntšoa ha solvent, pula, electrolysis, mokhoa oa phapanyetsano ea ion, tlhahlobo ea letsoai Ema. Har&39;a bona, mokhoa oa ho ntša solvent o sebelisoa ka litsela tse ngata, ka tšilafalo e tlaase, tšebeliso e tlaase ea matla, phello e phahameng ea karohano le bohloeki ba lihlahisoa, le khetho le nts&39;etsopele ea li-extractants tse sebetsang hantle le tse theko e tlaase, ka katleho ho fokotsa litšenyehelo tsa ts&39;ebetso, le ho hlahloba ho eketsehileng ha li-extractants tse fapa-fapaneng tsa li-synergies e ka ba e &39;ngoe ea litaelo tsa sepheo sa tšimo ena.

Ho feta moo, mokhoa oa pula e boetse ke senotlolo sa tataiso e &39;ngoe ea lipatlisiso tsa eona ka lebaka la melemo ea eona ea sekhahla se phahameng sa ho hlaphoheloa, litšenyehelo tse tlaase le ts&39;ebetso e phahameng. Hajoale, bothata ba bohlokoa boteng ba mokhoa oa pula bo tlase, ka hona, mabapi le khetho le maemo a ts&39;ebetso ea sedimentation, e tla laola tatellano ea pula ea privalent ea tšepe, ka hona ho eketsa bohloeki ba sehlahisoa ho tla ba le litebello tse ntle tsa kopo ea indasteri. Ka nako e ts&39;oanang, ts&39;ebetsong ea ts&39;ilafalo ea betri ea lithium-ion, tšilafalo ea bobeli joalo ka mokelikeli oa litšila, masala a litšila a ke ke a thibeloa, &39;me kotsi ea tšilafalo ea bobeli e fokotsehile ha lisebelisoa li sebelisoa ho fumana litšila tsa lithium ion libetri.

Tikoloho, e sebetsang hantle le e theko e tlase rec.
