E nwere nnukwu ego nke na-adịghị emeghari ọhụrụ na elu aku na uba uru, dị ka cobalt, lithium, nickel, ọla kọpa, aluminum, wdg Ọ nwere ike ọ bụghị nanị ibelata mmetọ si n'efu batrị, ma zere imefusị metal onwunwe nke cobalt, nickel. , wdg site n'ịmegharị ihe mkpofu ma ọ bụ batrị lithium ion erughị eru.
Ktkbofan Energy New ihe Co. Ltd na Changzhou ka cooperated na mahadum na tọrọ ntọala a nnyocha otu dabeere na nkwado si Jiangsu nkụzi University of technology, Jiangsu obere metal usoro technology na ngwa isi laabu. Isiokwu nyocha ya bụ imegharị igwe bara uru sitere na batrị lithium ion mkpofu. Mgbe afọ atọ nnyocha na mmepe, ọ na-edozi okwu ndị mgbagwoju anya rụpụta, ogologo usoro, gburugburu ebe obibi ihe ize ndụ si organic mgbaze, shortened nkà na ụzụ usoro, ibelata ike oriri, mma metal recycle ọnụego, ịdị ọcha na mgbake, nke na-eme ka nweta nke kwa afọ. 8000 tọn batrị lithium ion na-ekpofu ihe eji emegharị na ngwa ejikọtara nke ọma.
Ọrụ a bụ nke iji akụrụngwa mkpofu siri ike. The teknuzu ụkpụrụ bụ segregating na recycling nonferrous ọla site hydrometallurgical mmịpụta, gụnyere leach, ngwọta ọcha na ịta, ihe mgbaze mmịpụta, wdg Ọ na-arụpụta elemental metal ngwaahịa site electrometallurgy Usoro (electrodeposition).
Usoro usoro a bụ: ọgwụgwọ mbụ na batrị lithium ion mkpofu na mbụ, gụnyere ịwụsa, igbasa, kụrie na nhazi. Mgbe ahụ megharịa rọba ahụ mgbe a gbasasịrị na ígwè n'èzí. Wepụ ihe ndị electrode mgbe alkaline leaching, acid leaching na refining.
Mwepụta bụ isi ihe na-ekewa ọla kọpa na cobalt na nickel. Mgbe ahụ, a na-etinye ọla kọpa ahụ n'ime oghere electrodeposition ma na-emepụta mmepụta ọla kọpa electroed. Wepụ ọzọ ka mwepụtachara nke cobalt na nickel. Anyị nwere ike nweta nnu cobalt na nnu nickel mgbe ịtachara kristal. Ma ọ bụ were cobalt na nickel mgbe mmịpụta gasịrị n'ime oghere electrodeposition, wee mepụta ngwaahịa cobalt na nickel elektrọn.
Nnweta nke cobalt, ọla kọpa na nickel na usoro ntinye ego elektrọn bụ 99.98%, 99.95% na 99.2% ~ 99.9%. Ma ngwaahịa cobaltous sulfate na nickel sulfate eruola ọkọlọtọ dị mkpa.
Nwee nyocha mgbasawanye & mmepụta ihe na mmepe na nsonaazụ nyocha kachasị mma, guzobe ahịrị nrụpụta dị ọcha nke batrị lithium ion mkpofu na mgbake kwa afọ nke ihe karịrị tọn 8000, megharịa 1500 tọn cobalt, 1200 tọn ọla kọpa, 420 tọn nickel, nke na-eri ihe karịrị nde yuan 400.
A na-ekwu na ọ dịghị hydrometallurgy n'ụlọ. A naghị ahụkarị ya na mba ọzọ. Ma eleghị anya, anyị nwere ike ịgbalị iji usoro a n'ime ngwa ngwa.
Mmezu a na-ebute ụzọ na mkpofu mba batrị ion imegharị ihe, ma na-emeju nchekwa ike nke ọma. Tụnyere ụlọ ọrụ batrị ndị ọzọ, ọ nwere uru pụtara ìhè gụnyere omume enyi na gburugburu ebe obibi, ọnụ ala dị ala na nnukwu uru.
Ọ nwere ike ijikọ na naanị usoro teknụzụ site na hydrometallurgy, nke nwere obere ume ike mana mgbake ngwaahịa dị elu.
