Indlela yokuphatha yeNkunkuma yebhetri yeLithium ion

Kukho inani elikhulu lokungahlaziywayo kunye nexabiso eliphezulu lezoqoqosho, njenge-cobalt, i-lithium, i-nickel, ithusi, i-aluminium, njl. , njl. ngokuphinda usebenzise inkunkuma okanye iibhetri ze-lithium ion ezingafanelekanga.

I-Ktkbofan Energy New Material Co. Ltd e-Changzhou ibambisene nekholeji kwaye yaseka iqela lophando elisekelwe kwinkxaso evela kubafundisi be-Jiangsu University of technology, i-Jiangsu enqabileyo iteknoloji yenkqubo yesinyithi kunye nelebhu engundoqo yesicelo. Isihloko sophando lwayo sihlaziya isinyithi esixabisekileyo kwi-lithium ion ibhetri. Emva kophando lweminyaka emithathu kunye nophuhliso, iye yasombulula imiba enzima yokwenziwa, inkqubo ende, iingozi zokusingqongileyo ukusuka kwi-solvent organic, inkqubo yobuchwepheshe efinyeziweyo, ukusetyenziswa kwamandla okucuthayo, ukuphucula izinga lokuphinda kusetyenziswe isinyithi, ukucoceka kunye nokubuyisela, okwenza ukufezekiswa konyaka. I-8000 yeetoni zenkunkuma ye-lithium ion ibhetri efakwe ngokupheleleyo-efakwe ngokutsha kunye nokusetyenziswa.

Le projekthi yeyokusetyenziswa kwenkunkuma eqinileyo. Umgaqo wobugcisa ukwahlula kunye nokuphinda kusetyenziswe isinyithi esingenamvubelo nge-hydrometallurgical extraction, kubandakanywa i-leach, ukucocwa kwesisombululo kunye nokugxininiswa, ukukhutshwa kwe-solvent, njl.

Amanyathelo obuchule ngala: Unyango lwangaphambili kwinkunkuma ye-lithium ion ibhetri ekuqaleni, kubandakanywa ukukhupha, ukuqhaqha, ukutyumza kunye nokuhlelwa. Emva koko uphinde usebenzise iplastiki emva kokuqhawula kunye nentsimbi ngaphandle. Khipha izinto ze-electrode emva kwe-alkaline leaching, i-acid leaching kunye nokucocwa.

Ukukhupha linyathelo eliphambili lokuhlula ubhedu kwi-cobalt kunye ne-nickel. Emva koko ubhedu lufakwe kwi-slot ye-electrodeposition kwaye ivelise imveliso yobhedu efakwe kwi-electro. Khupha kwakhona emva kokukhutshwa kwe-cobalt kunye ne-nickel. Sinokufumana ityuwa ye-cobalt kunye netyuwa ye-nickel emva koxinzelelo lwe-crystallized. Okanye thatha i-cobalt kunye ne-nickel emva kokutsalwa kwi-slot ye-electrodeposition, uze wenze i-electro deposited cobalt kunye neemveliso ze-nickel.

Ukubuyiswa kwe-cobalt, ubhedu kunye ne-nickel kwinkqubo ye-electro-deposition yi-99.98%, 99.95% kunye ne-99.2% ~ 99.9%. Zombini i-cobaltous sulfate kunye neemveliso ze-nickel sulfate zifikelele kumgangatho ofanelekileyo.

Yiba nolwandiso kunye nophando loshishino kunye nophuhliso kwimpumelelo yophando oluphuculweyo, ukuseta umgca wemveliso ococekileyo ovalelweyo wenkunkuma ye-lithium ion yebhetri kunye nokubuyiswa konyaka kweetoni ezingaphezu kwama-8000, ukuhlaziya iitoni eziyi-1500 zecobalt, iitoni ezingama-1200 zobhedu, iitoni ezingama-420 zenikeli ixabisa ngaphezu kwezigidi ezingama-400 zeeyuan.

Kuthiwa akukho hydrometallurgy ekhaya. Ayifane ibonakale kumazwe angaphandle. Mhlawumbi singazama ukuthatha le ndlela kwisicelo esibanzi.

Le mpumelelo idlala indima ephambili kwinkunkuma yesizwe Li ion ibhetri ukurisayikilisha, kunye nokongeza ngempumelelo ugcino lwamandla. Xa ithelekiswa namanye amashishini ebhetri, ineengenelo ezicacileyo ezibandakanya indalo esingqongileyo, ixabiso eliphantsi kunye nengeniso ephezulu.

Inokudibanisa kwaye ngokulula inkqubo yetekhnoloji nge-hydrometallurgy, esebenzisa amandla aphantsi kodwa ukubuyiswa kwemveliso ephezulu.
