Kunenani elikhulu lokungavuseleleki ngenani eliphezulu lezomnotho, njenge-cobalt, i-lithium, i-nickel, ithusi, i-aluminium, njll. Ngeke nje yehlise ukungcola okuvela ebhethri elilahlwayo, kodwa futhi igweme ukumosha izinsiza zensimbi ze-cobalt, i-nickel. , njll. ngokuvuselela kabusha imfucuza noma amabhethri e-lithium ion angafanelekile.
I-Ktkbofan Energy New Material Co. Ltd e-Changzhou ibambisene nekolishi futhi yasungula iqembu locwaningo elisekelwe ekusekelweni kothisha base-Jiangsu University of Technology, ubuchwepheshe benqubo yensimbi engavamile ye-Jiangsu kanye nelabhorethri yokhiye wokufaka isicelo. Isihloko sayo socwaningo sigaya kabusha insimbi ebalulekile kusuka kudoti webhethri ye-lithium ion. Ngemuva kweminyaka emithathu yocwaningo nentuthuko, ixazulule izingqinamba zokwakhiwa okuyinkimbinkimbi, inqubo ende, izingozi zemvelo ezivela ku-solvent ye-organic, inqubo efinyeziwe yezobuchwepheshe, ukuncipha kokusetshenziswa kwamandla, kuthuthukiswe izinga lokugaywa kabusha kwensimbi, ukuhlanzeka kanye nokululama, okwenza ukuphumelela konyaka. 8000 ton imfucuza yebhethri ye-lithium ion evaleleke ngokugcwele nokusetshenziswa kwayo.
Le phrojekthi ingeyokusetshenziswa kwemithombo kadoti eqinile. Umgomo wezobuchwepheshe ukuhlukanisa nokuvuselela izinsimbi ezingenayo insimbi ngokukhipha i-hydrometallurgical, okuhlanganisa i-leach, ukuhlanzwa kwesixazululo nokugxilisa ingqondo, ukukhishwa kwe-solvent, njll. Iphinde ikhiqize umkhiqizo wensimbi oyisici nge-electrometallurgy technique (electrodeposition).
Izinyathelo zesu yilezi: ukwehliswa kusengaphambili kudoti webhethri ye-lithium ion ekuqaleni, okuhlanganisa nokukhipha, ukuqaqa, ukuphihliza nokuhlunga. Bese uphinda usebenzise ipulasitiki ngemuva kokuyiqaqa bese uyi-ayina ngaphandle. Khipha izinto ze-electrode ngemva kokucwiliswa kwe-alkaline, ukucwiliswa kwe-asidi nokucwengwa.
Ukukhipha kuyisinyathelo esibalulekile sokuhlukanisa ithusi ku-cobalt ne-nickel. Khona-ke ithusi lifakwa ku-slot ye-electrodeposition futhi ikhiqize ukukhiqizwa kwethusi kwe-electro. Khipha futhi ngemva kokukhipha i-cobalt ne-nickel. Singathola usawoti we-cobalt kanye nosawoti we-nickel ngemuva kokugxila okucwebezelayo. Noma thatha i-cobalt ne-nickel ngemva kokukhipha ku-electrodeposition slot, bese wenza imikhiqizo ye-cobalt ne-nickel efakwe ku-electro.
Ukutholwa kwe-cobalt, ithusi kanye ne-nickel ekusetshenzisweni kwe-electro-deposition kungu-99.98%, 99.95% kanye no-99.2% ~99.9%. Kokubili imikhiqizo ye-cobaltous sulfate ne-nickel sulfate ifinyelele izinga elifanele.
Yiba nocwaningo lokunwetshwa kwezinga kanye nezimboni futhi uthuthukise impumelelo yocwaningo eyenziwe kahle, usethe umugqa wokukhiqiza ohlanzekile ovalelwe ngokugcwele webhethri ye-lithium ion enokubuyiselwa konyaka ngamathani angaphezu kuka-8000, ubuyisele kabusha amathani ayi-1500 cobalt, amathani ayi-1200 ethusi, amathani angama-420 we-nickel, ibiza ngaphezu kwama-yuan ayizigidi ezingama-400.
Kuthiwa akukho hydrometallurgy ekhaya. Akuvamile ukubonakala emazweni angaphandle. Mhlawumbe singazama ukusebenzisa le ndlela ekusetshenzisweni okubanzi.
Le mpumelelo idlala indima ehamba phambili kudoti kazwelonke Ibhethri ye-Li ion ukugaywa kabusha, futhi kugcwalise ngempumelelo isitoreji samandla. Uma iqhathaniswa namanye amabhizinisi amabhethri, inezinzuzo ezisobala ezihlanganisa nobungane bemvelo, izindleko eziphansi kanye nenzuzo ephezulu.
Ingakwazi ukuhlanganisa futhi imane inqubo yezobuchwepheshe nge-hydrometallurgy, esebenzisa amandla aphansi kodwa ukubuyisela umkhiqizo ophezulu.
phendula kungakapheli amahora angu-6, noma yimiphi imibuzo wamukelekile!
