Habkani waa mid fudud, sahlan in la shaqeeyo oo hooseeya, laakiin xaaladaha kala duwan ee ions birta ah, oo leh roobabka cusbada kale ee birta ah, taas oo yaraynaysa nadiifinta alaabta. Jin Yujian et al, marka loo eego aragtida casriga ah ee xalka elektrolytka, isticmaalka baytariyada lithium ion salinated. A saturated (NH4) 2SO4 xal aqueous iyo ethanol anhydrous ayaa lagu daray dareere HCl leaching ka LiiCoO2 sida electrode wanaagsan, iyo marka xal, saturated (NH4) 2SO4 xal aqueous iyo ethanol anhydrous ahaayeen 2: 1: 3, CO2 + heerka roobab ka badan 92%.

Badeecada cusbada leh ee ka soo baxday waa (NH4) 2CO (SO4) 2 iyo (NH4) Al (SO4) 2, kuwaas oo adeegsada milix kala qaybsan si ay u kala saaraan labada milix, si ay u helaan badeecooyin kala duwan. Ku saabsan soo saarista iyo kala-soocidda birta qiimaha leh ee qashinka lithium ion batari leach, kor ku xusan waa dhowr siyaabood oo wax badan loo barto. Iyadoo la tixgelinayo arrimo ay ka mid yihiin mugga farsamaynta, kharashka hawlgalka, nadiifinta alaabta iyo wasakhowga sare, Shaxda 2 waxay soo koobaysaa habka farsamada ee isbarbardhigga dhowr biraha kala soocida ee kor lagu sharaxay.

Waqtigan xaadirka ah, adeegsiga baytariyada lithium-ion ee tamarta korantada iyo dhinacyo kale ayaa aad u ballaaran, tirada qashinka lithium-ion baytariyada lama dhayalsan karo. Marxaladdan, habka soo kabashada baytariga lithium-ion ee aan qashinka lahayn ayaa muhiim u ah daawaynta ka hor - dib-u-warshadaynta-leaching-qoyan. Daawadii hore waxaa ka mid ah daadinta, burburinta iyo kala soocida walxaha korantada, iwm.

Waxaa ka mid ah, habka kala diriddu waa mid fudud, waxayna si wax ku ool ah u wanaajin kartaa saameynta kala-soocidda iyo heerka soo kabashada, laakiin dareeraha hadda la isticmaalo ee muhiimka ah (NMP) waa qaali ilaa xad, sidaas darteed codsiga dareeraha ku habboon ayaa mudan in la baaro arrintan. Mid ka mid ah tilmaamaha. Habka dheecaanku wuxuu muhiim u yahay wakiilka yareeya aashitada sida wakiilka leaching, kaas oo gaari kara saameyn leaching la doorbido, laakiin waxaa jiri doona wasakh labaad sida dareeraha wasakhda ah ee dabiiciga ah, iyo habka bayoolojigu wuxuu leeyahay faa&39;iido waxtar leh, ilaalinta deegaanka iyo qiimo jaban, laakiin waxaa jira bir muhiim ah.
