Hanyar Gudanar da Batir Lithium ion Sharar gida

Akwai adadi mai yawa na waɗanda ba a sabunta su ba tare da ƙimar tattalin arziki mai girma, irin su cobalt, lithium, nickel, jan ƙarfe, aluminum, da sauransu. , da sauransu ta hanyar sake yin amfani da sharar gida ko batirin lithium ion da bai cancanta ba.

Ktkbofan Energy New Material Co. Ltd a Changzhou ya hada gwiwa tare da kwaleji da kuma kafa wani bincike kungiyar bisa goyon baya daga Jiangsu malamai Jami'ar fasaha, Jiangsu rare karfe aiwatar fasahar da aikace-aikace key dakin gwaje-gwaje. Taken bincikensa shine sake yin amfani da ƙarfe mai mahimmanci daga batirin lithium ion sharar gida. Bayan shekaru uku bincike da ci gaba, shi ya warware al'amurran da suka shafi rikitarwa masana'anta, dogon tsari, muhalli hatsarori daga Organic sauran ƙarfi, taqaitaccen fasaha tsari, rage amfani da wutar lantarki, inganta karfe sake yin fa'ida kudi, da tsarki da kuma dawo da, wanda ya sa nasarar shekara-shekara. Batirin lithium ion ton 8000 sharar gida da aikace-aikace.

Wannan aikin nasa ne na amfani da albarkatun datti. The fasaha manufa ne segregating da sake amfani da nonferrous karafa da hydrometallurgical hakar, ciki har da leach, bayani tsarkakewa da maida hankali, sauran ƙarfi hakar, da dai sauransu Har ila yau, samar da elemental karfe samfurin da electrometallurgy dabara (electrodeposition).

Matakan dabarun sune: riga-kafi akan batir lithium ion sharar gida da farko, gami da fitarwa, tarwatsawa, fasawa da rarrabuwa. Sa'an nan kuma sake sarrafa robobi bayan tarwatsa da ƙarfe a waje. Cire kayan lantarki bayan leaching alkaline, leaching acid da tacewa.

Ciro shine mabuɗin matakin raba jan ƙarfe daga cobalt da nickel. Sa'an nan kuma an saka tagulla a cikin ramin electrodeposition kuma yana samar da wutar lantarki da aka adana tagulla. Cire kuma bayan hakar cobalt da nickel. Zamu iya samun gishirin cobalt da gishirin nickel bayan taro mai kristal. Ko kuma a ɗauki cobalt da nickel bayan an cire su a cikin rami na electrodeposition, sannan a yi samfuran cobalt da nickel ɗin da aka ajiye na lantarki.

Abubuwan da aka dawo da cobalt, jan ƙarfe da nickel akan tsarin sakawa na lantarki shine 99.98%, 99.95% da 99.2% ~ 99.9%. Duka samfuran sulfate na cobaltous da nickel sulfate sun kai matsayin da ya dace.

Yi bincike-bincike-faɗawa & masana'antu da haɓaka kan ingantacciyar nasarar bincike, kafa cikakkiyar layin samarwa mai tsabta na batir lithium ion mai sharar gida tare da dawo da tan 8000 na shekara-shekara, sake yin fa'ida 1500 ton cobalt, tan 1200 jan ƙarfe, tan nickel 420, wanda gaba daya kudinsa ya haura yuan miliyan 400.

An ce babu hydrometallurgy a gida. Haka kuma ba kasafai ake ganinsa a kasashen waje ba. Wataƙila za mu iya ƙoƙarin ɗaukar wannan hanyar zuwa aikace-aikace mai faɗi.

Wannan nasara tana taka rawa a sharar gida Li ion baturi sake yin amfani da su, da kuma samun nasarar haɓaka makamashin makamashi. Idan aka kwatanta da sauran kamfanonin batir, yana da fa'idodi na fili sun haɗa da yanayin muhalli, ƙarancin farashi da riba mai yawa.

Yana iya haɗawa kuma kawai tsarin fasaha ta hanyar hydrometallurgy, wanda ke da ƙarancin amfani da makamashi amma babban dawo da samfurin.
