Mokhoa oa ho sebetsana le Betri ea Lithium Ion

Ho na le palo e kholo ea lintho tse sa tsosolositsoeng tse nang le boleng bo phahameng ba moruo, tse kang cobalt, lithium, nickel, koporo, aluminium, joalo-joalo E ke ke ea fokotsa tšilafalo e tsoang ho betri ea litšila, empa hape e qoba ho senya lisebelisoa tsa tšepe tsa cobalt, nickel. , joalo-joalo ka ho tsosolosa litšila kapa libeteri tsa lithium ion tse sa tšoaneleheng.

Ktkbofan Energy New Material Co. Ltd e Changzhou e sebelisana le k'holejeng 'me e thehile sehlopha sa lipatlisiso se thehiloeng ho tšehetso e tsoang ho matichere a Jiangsu University of Technology, Jiangsu rare metal process technology and application key laboratory. Sehlooho sa eona sa lipatlisiso ke ho tsosolosa tšepe ea bohlokoa ho tloha litšila tsa lithium ion battery. Kamora ho etsa lipatlisiso le nts'etsopele ea lilemo tse tharo, e rarolotse litaba tsa tlhahiso e rarahaneng, ts'ebetso e telele, likotsi tsa tikoloho ho tsoa ho solvent ea manyolo, ts'ebetso ea thekenoloji e khutsufalitsoeng, tšebeliso e fokotsehileng ea matla, e ntlafalitse sekhahla sa ts'ebetso ea tšepe, bohloeki le ho hlaphoheloa, e leng se etsang hore ho fihlellehe ha selemo le selemo. Lithane tse 8000 tsa litšila tsa lithium ion betri e kentsoeng ka botlalo le ts'ebeliso.

Morero ona ke oa ts'ebeliso ea litšila tse tiileng. Molao-motheo oa tekheniki ke ho arola le ho tsosolosa litšepe tse se nang ferrous ka ho ntšoa ha hydrometallurgical, ho kenyelletsa le leach, ho hloekisa tharollo le mahloriso, ho ntšoa ha solvent, joalo-joalo. E boetse e hlahisa sehlahisoa sa tšepe ea motheo ka mokhoa oa electrometallurgy (electrodeposition).

Mehato ea mahlale ke: ho ts'oaroa esale pele ka betri ea lithium ion qalong, ho kenyelletsa ho lahla, ho qhaqholla, ho pshatla le ho hlopha. Ebe u sebelisa polasetiki hape ka mor'a ho qhaqhoa le tšepe ka ntle. Ntša lisebelisoa tsa elektrode ka mor'a hore alkaline leaching, acid leaching le ho hloekisa.

Ho ntša ke mohato oa bohlokoa oa ho arola koporo ho cobalt le nickel. Ebe koporo e kenngoa ka har'a sekotjana sa electrodeposition mme e hlahisa tlhahiso ea koporo e kentsoeng ka electro. Ntša hape ka mor'a ho ntšoa ha cobalt le nickel. Re ka fumana letsoai la cobalt le letsoai la nickel ka mor'a mahloriso a kristale. Kapa u nke cobalt le nickel ka mor'a ho e ntša ka har'a slot ea electrodeposition, ebe u etsa electro deposited cobalt le lihlahisoa tsa nickel.

Ho khutlisoa ha cobalt, koporo le nickel ts'ebetsong ea electro-deposition ke 99.98%, 99.95% le 99.2% ~ 99.9%. Lihlahisoa ka bobeli tsa cobaltous sulfate le nickel sulfate li fihlile maemong a nepahetseng.

Ho ba le lipatlisiso tsa katoloso le tsa indasteri le ho nts'etsapele katlehong e ntlafalitsoeng ea lipatlisiso, theha mohala o koaletsoeng o hloekileng oa betri ea lithium ion ka ho hlaphoheloa selemo le selemo ka lithane tse fetang 8000, sebelisa cobalt ea lithane tse 1500, koporo ea lithane tse 1200, nickel ea lithane tse 420. theko e felletseng e feta li-yuan tse limilione tse 400.

Ho boleloa hore ha ho na hydrometallurgy lapeng. E boetse e bonoa ka seoelo linaheng tse ling. Mohlomong re ka leka ho sebelisa mokhoa ona ka mokhoa o pharaletseng.

Katleho ena e na le seabo se ka sehloohong ho litšila tsa naha Betri ea li-ion botjha, mme ka katleho e tlatselletsa polokelo ya eneji. Ha e bapisoa le likhoebo tse ling tsa li-betri, e na le melemo e bonahalang e kenyelletsa botsoalle ba tikoloho, litšenyehelo tse tlase le phaello e phahameng.

E ka kopanya le ts'ebetso ea thekenoloji feela ka hydrometallurgy, e nang le tšebeliso e tlase ea matla empa ho hlaphoheloa ha sehlahisoa se phahameng.
