Njira Yoyendetsera Zinyalala Battery Lithium Ion

Pali zochuluka zosasinthika zomwe zili ndi mtengo wapamwamba wachuma, monga cobalt, lithiamu, faifi tambala, mkuwa, aluminiyamu, ndi zina zotero. Izo sizingakhoze kokha kuchepetsa kuipitsidwa kwa zinyalala batire, komanso kupewa kuwononga zitsulo chuma cobalt, faifi tambala. , etc. pokonzanso zinyalala kapena osayenera lithiamu ion mabatire.

Ktkbofan Energy New Material Co. Ltd ku Changzhou agwirizana ndi koleji ndipo anayambitsa gulu kafukufuku zochokera thandizo la Jiangsu aphunzitsi University of luso, Jiangsu osowa zitsulo ndondomeko luso ndi ntchito zasayansi kiyi. Mutu wake wofufuza ndikubwezeretsanso zitsulo zamtengo wapatali kuchokera ku zinyalala za lithiamu ion batire. Pambuyo zaka zitatu kafukufuku ndi chitukuko chathetsa nkhani za kupanga zovuta, ndondomeko yaitali, kuopsa kwa chilengedwe ku zosungunulira organic, kufupikitsa ndondomeko zamakono, utachepa mowa mphamvu, bwino zitsulo zobwezeretsanso mlingo, chiyero ndi kuchira, zomwe zimapangitsa kukwaniritsa pachaka. 8000 tani zinyalala batire lithiamu ion kwathunthu-otsekedwa yobwezeretsanso ndi ntchito.

Pulojekitiyi ndi yogwiritsa ntchito zinyalala zolimba. Mfundo luso ndi kulekanitsa ndi zobwezeretsanso zitsulo nonferrous ndi hydrometallurgical m'zigawo, kuphatikizapo leach, njira kuyeretsedwa ndi ndende, zosungunulira m'zigawo, etc. Komanso limapanga elemental zitsulo mankhwala ndi electrometallurgy njira (electrodeposition).

Njira zake ndi izi: pretreatment pa zinyalala lithiamu ion batire poyamba, kuphatikizapo kutulutsa, disassembling, kuswa ndi kusanja. Kenako bwezeretsaninso pulasitikiyo mukatha disassemble ndi chitsulo chakunja. Tulutsani ma elekitirodi pambuyo pa kukhetsa kwa alkaline, kutulutsa kwa asidi ndi kuyenga.

Kutulutsa ndi gawo lofunikira pakulekanitsa mkuwa kuchokera ku cobalt ndi faifi tambala. Kenako mkuwa umayikidwa mu electrodeposition slot ndikupanga electrodesign copper kupanga. Tingafinye kachiwiri pambuyo m'zigawo za cobalt ndi faifi tambala. Titha kupeza mchere wa cobalt ndi mchere wa nickel pambuyo poti sunganizidwe bwino. Kapena tengani cobalt ndi faifi tambala mutatha kutulutsa mu electrodeposition slot, kenaka pangani ma electrodesign cobalt ndi faifi tambala.

Kubwezeretsedwa kwa cobalt, mkuwa ndi faifi tambala pa electro-deposition process ndi 99.98%, 99.95% ndi 99.2% ~ 99.9%. Zonse za cobaltous sulfate ndi nickel sulfate zafika pamlingo woyenera.

Khalani ndi kukula & kafukufuku wamafakitale ndi chitukuko pa kupindula wokometsedwa kafukufuku, kukhazikitsa anatsekedwa kwathunthu woyera kupanga mzere zinyalala lifiyamu ion batire ndi kuchira pachaka matani oposa 8000, akonzanso matani 1500 cobalt, matani 1200 mkuwa, 420 matani faifi tambala, amene mtengo wake upitilira 400 miliyoni yuan.

Akuti kunyumba kulibe hydrometallurgy. Siziwonekanso kawirikawiri m'mayiko akunja. Mwina tingayesetse kugwiritsa ntchito njira imeneyi mokulirapo.

Kupindulaku kumagwira ntchito yotsogolera pa zinyalala za dziko Li ion batri kubwezeretsanso, ndikuwonjezera bwino kusungirako mphamvu. Poyerekeza ndi mabizinesi ena a batri, ili ndi maubwino owoneka ngati okonda zachilengedwe, otsika mtengo komanso phindu lalikulu.

Itha kuphatikizira komanso njira yaukadaulo ndi hydrometallurgy, yomwe imakhala ndi mphamvu zochepa koma kuchira kwazinthu zambiri.
