Habka Loo Maareeyo Qashinka Lithium Ion Battery

Waxaa jira xaddi badan oo aan la cusboonaysiin karin oo leh qiime sare oo dhaqaale, sida kobalt, lithium, nikkel, copper, aluminium, iwm. Ma yarayn karto oo kaliya wasakhowga batteriga qashinka, laakiin sidoo kale iska ilaali in la lumiyo khayraadka birta ah ee kobalt, nikkel , iwm. adoo dib u warshadeynaya qashinka ama baytariyada lithium ion ee aan u qalmin.

Ktkbofan Energy New Material Co. Ltd ee Changzhou ayaa iskaashi la college iyo aasaasay koox cilmi ku salaysan taageero ka macalimiinta Jiangsu University of technology, Jiangsu technology habka biraha dhif iyo shaybaar muhiimka ah codsiga. Mawduuceeda cilmi-baaristu waa dib-u-warshadaynta birta qiimaha leh ee batteriga lithium ion qashinka ah. Cilmi-baaris saddex sano ah iyo horumarinta ka dib, waxay xallisay arrimaha soo saarista adag, geeddi-socodka dheer, khatarta deegaanka ee ka soo baxa dareeraha organic, geeddi-socodka teknoolajiyada gaaban, isticmaalka awoodda hoos u dhaca, hagaajinta heerka dib-u-warshadaynta birta, nadiifinta iyo soo kabashada, taas oo ka dhigaysa guusha sanadlaha ah. 8000 oo tan qashinka lithium ion baytari si buuxda u xidhan dib u warshadaynta iyo codsiga.

Mashruucan waxaa iska leh ka faa'iidaysiga kheyraadka qashinka adag. Mabda'a farsamada waa kala soocidda iyo dib-u-warshadaynta biraha nonferrous by saarista hydrometallurgical, oo ay ku jiraan leach, nadiifinta xal iyo fiirsashada, fiirsashada dareeraha, iwm Waxa kale oo ay soo saartaa alaabta birta element by farsamada electrometallurgy (electrodeposition).

Tillaabooyinka farsamadu waa: ka horraysiinta qashinka lithium ion baytari marka hore, oo ay ku jiraan sii dayn, kala dirid, jajabinta iyo kala soocidda. Kadibna dib u warshadeeyo balaastiig ka dib kala furfurid iyo birta dibadda. Soo saar walxaha korantada ka dib dheecaanka alkaline, dheecaanka aashitada iyo nadiifinta.

Soo saaristu waa tallaabada ugu muhiimsan ee kala soocida naxaasta kobalt iyo nikkel. Kadibna naxaasta waxaa la geliyaa booska electrodeposition waxayna soo saartaa wax soo saarka naxaasta ee korantada. Mar labaad soo saar ka dib marka la soo saaro kobalt iyo nikkel. Waxaan heli karnaa milix kobalt ah iyo cusbo nikkel ka dib marka la isku koobo. Ama qaado cobalt iyo nikkel ka dib marka laga soo saaro booska electrodeposition, ka dibna ka samee kobalt iyo nikkel kaydinta electrode.

Soo kabashada cobalt, naxaasta iyo nikkel ee habka kaydinta korantada waa 99.98%, 99.95% iyo 99.2% ~99.9%. Labada badeecadood ee kobaltous sulfate iyo nikkel sulfate labaduba waxay gaadheen heer ku habboon.

Hayso cilmi-baaris miisaan-ballaadhin ah iyo warshadaynta oo horumarisa guusha cilmi-baarista ee la wanaajiyey, deji khad wax-soo-saar nadiif ah oo si buuxda u xiran oo ah batari lithium ion qashinka ah oo leh soo kabasho sanadle ah oo ka badan 8000 tan, dib-u-warshad 1500 tan cobalt, 1200 tan oo naxaas ah, 420 tan nikkel, kaas oo Guud ahaan waxa ku kacaya in ka badan 400 milyan yuan.

Waxaa la sheegay in guriga uusan ka jirin hydrometallurgy. Sidoo kale waa dhif in lagu arko dalal shisheeye. Waxaa laga yaabaa inaan isku dayi karno inaan habkan u qaadano codsi ballaaran.

Guushani waxa ay door hormuud ah ka ciyaartaa qashinka qaranka Li ion batari dib u warshadaynta, iyo si guul leh u kabida kaydinta tamarta. Marka la barbar dhigo shirkadaha kale ee batteriga, waxa ay leedahay faa'iidooyin muuqda oo ay ka mid yihiin deegaanka saaxiibtinimo, qiimo jaban iyo faa'iido sare.

Waxay isku dari kartaa oo si fudud u dhexgelin kartaa habka tignoolajiyada ee loo yaqaan 'hydrometallurgy', kaas oo leh isticmaalka tamarta hooseeya laakiin soo kabashada alaabta sare.
