Waqtigan xaadirka ah, baytariyada lithium ion waxay door muhiim ah ka ciyaareen nolosha dadka, laakiin weli waxaa jira dhibaatooyin ku jira tiknoolajiyada baytariyada lithium. Sababta ugu weyn ayaa ah in elektrolytka loo isticmaalo baytariyada lithium uu yahay lithium hexafluorophosphate, kaas oo aad ugu nugul qoyaanka isla markaana leh waxqabad heerkul sare. Alaabooyinka xasilloonida iyo kala-goysyadu waxay u nugul yihiin walxaha elektrolytka, taasoo keenta waxqabadka badbaadada liita ee baytariyada lithium. Isla mar ahaantaana, LiPF6 waxay sidoo kale leedahay dhibaatooyin sida milmi la'aan liidata iyo koronto-qaadis hooseeya oo ku jirta jawi heerkul hooseeya, kuwaas oo aan dabooli karin isticmaalka baytariyada lithium ee awoodda leh. Sidaa darteed, aad ayey muhiim u tahay in la sameeyo cusbo lithium elektrolyt ah oo cusub oo leh waxqabad aad u wanaagsan.
Ilaa hadda, hay'adaha cilmi-baarista waxay sameeyeen noocyo kala duwan oo cusbo lithium elektrolyt ah oo cusub, kuwa ugu badan ee matalaya waa lithium tetrafluoroborate iyo lithium bis-oxalate borate. Kuwaas waxaa ka mid ah, lithium bis-oxalate borate ma fududa in lagu burburiyo heerkulka sare, aan u nugulayn qoyaanka, habka isku-darka fudud, maya Waxay leedahay faa'iidooyinka wasakhowga, xasilloonida electrochemical, daaqad ballaaran, iyo awoodda lagu sameeyo filim SEI oo wanaagsan oo ku yaal dusha sare ee elektrolytka taban, laakiin milmida hooseeya ee elektrolytka ee dareeraha carbonate toosan waxay horseedaa inuu hooseeyo, gaar ahaan waxqabadkiisa heerkulka hooseeya. Cilmi-baaris ka dib, waxaa la ogaaday in lithium tetrafluoroborate uu leeyahay milmi weyn oo ku jira dareeraha carbonate sababtoo ah cabbirka yar ee molecular, kaas oo si wax ku ool ah u hagaajin kara waxqabadka heerkulka hooseeya ee baytariyada lithium, laakiin ma samayn karo filim SEI ah oo ku yaal dusha sare ee elektrolytka taban. Elektrolytka lithium milix lithium difluorooxalate borate, sida laga soo xigtay astaamaha qaab-dhismeedka, lithium difluorooxalate borate wuxuu isku daraa faa'iidooyinka lithium tetrafluoroborate iyo lithium bis-oxalate borate qaab-dhismeedka iyo waxqabadka, ma aha oo kaliya dareeraha carbonate toosan. Isla mar ahaantaana, waxay yareyn kartaa daxalka elektroolka waxayna kordhin kartaa socodka, taasoo sii wanaajinaysa waxqabadka heerkulka hooseeya iyo waxqabadka heerka baytariyada lithium ion. Lithium difluorooxalate borate sidoo kale waxay samayn kartaa lakab sifooyin qaab-dhismeed ah oo ku yaal dusha sare ee elektroodhka taban sida lithium bisoxalate borate. Filim SEI oo wanaagsan ayaa ka weyn.
Vinyl sulfate, oo ah wax kale oo lagu daro milix aan lithium ahayn, sidoo kale waa wax lagu daro sameynta filimka SEI, kaas oo joojin kara hoos u dhaca awoodda bilowga ah ee batteriga, kordhin kara awoodda sii deynta bilowga ah, yareyn kara ballaarinta batteriga ka dib marka la dhigo heerkul sare, iyo wanaajin kara waxqabadka dallacaadda-sii deynta batteriga, taas oo ah, tirada wareegyada. . Sidaas darteed, kordhinta adkeysiga sare ee batteriga iyo kordhinta cimriga adeegga batteriga. Sidaa darteed, rajada horumarinta ee waxyaabaha lagu daro elektrolytka ayaa sii kordheysa, baahida suuquna way sii kordheysaa.
Sida ku xusan "Buugga Tilmaamaha Hagaajinta Qaab-dhismeedka Warshadaha (Daabacaadda 2019)", waxyaabaha lagu daro elektrolytka ee mashruucan waxay la jaan qaadayaan qaybta koowaad ee qaybta dhiirigelinta, Qodobka 5 (tamarta cusub), qodobka 16 "horumarinta iyo adeegsiga tignoolajiyada tamarta cusub ee moobaylka", Qodobka 11 (Warshadaha kiimikada ee batroolka) qodobka 12 "dhalaal la beddelay, oo ku salaysan biyaha iyo dhejisyo cusub oo kulul dhalaaliya, nuugayaasha biyaha ee deegaanka u fiican, wakiilada daaweynta biyaha, meerkuriga adag ee shaandhada molecular, aan lahayn meerkuri iyo waxyaabo kale oo cusub oo waxtar leh oo deegaanka u fiican, walxaha nano, Horumarinta iyo soo saarista agabka xuubka shaqeynaya, reagents-ka aadka u nadiifsan oo saafi ah, photoresists, gaasaska elektaroonigga ah, agabka kiristaalka dareeraha ah ee waxqabadka sare leh iyo kiimikooyin kale oo cusub oo wanaagsan; Sida ku cad dib u eegista iyo falanqaynta dukumentiyada siyaasadda warshadaha ee qaranka iyo kuwa maxalliga ah sida "Ogeysiiska Liiska Taban ee Horumarinta Suumanka Dhaqaalaha (ee Hirgelinta Tijaabada)" (Dokumentiga Xafiiska Changjiang No. 89), waxaa la go'aamiyay in mashruucani uusan ahayn mashruuc horumarineed oo xaddidan ama mamnuuc ah.
Tamarta la isticmaalo marka mashruucu gaaro awoodda wax soo saarka waxaa ka mid ah koronto, uumi iyo biyo. Waqtigan xaadirka ah, mashruucu wuxuu qaataa tignoolajiyada wax soo saarka ee horumarsan ee warshadaha iyo qalabka, wuxuuna qaataa tallaabooyin kala duwan oo lagu badbaadinayo tamarta. Ka dib markii la isticmaalay, dhammaan tilmaamayaasha isticmaalka tamarta waxay gaareen heer sare oo isla warshaddaas ah ee Shiinaha, waxayna la jaan qaadayaan qeexitaannada naqshadeynta badbaadinta tamarta ee qaranka iyo warshadaha, heerarka la socodka badbaadinta tamarta iyo qalabka. Heerka hawlgalka dhaqaalaha; ilaa inta mashruucu hirgelinayo tilmaamayaasha waxtarka tamarta ee kala duwan, tilmaamayaasha isticmaalka tamarta ee wax soo saarka iyo tallaabooyinka badbaadinta tamarta ee lagu soo jeediyay warbixintan inta lagu jiro dhismaha iyo wax soo saarka, mashruucu waa mid macquul ah marka laga eego aragtida isticmaalka tamarta ee macquulka ah. Iyada oo lagu saleynayo tan, waxaa la go'aaminayaa in mashruucu uusan ku lug lahayn isticmaalka kheyraadka khadka tooska ah.
Cabbirka naqshadeynta mashruuca waa: lithium difluorooxalate borate 200t/a, kaas oo 200t/a lithium tetrafluoroborate loo isticmaalo sidii agabka ceeriin ee badeecooyinka lithium difluorooxalate borate, iyada oo aan la samayn shaqo ka dib, laakiin sidoo kale waxaa loo soo saari karaa sidii badeeco dhammaystiran oo si gaar ah loogu talagalay iyadoo loo eegayo baahida suuqa. Vinyl sulfate waa 1000t/a. Eeg Shaxda 1.1-1
