Waqtigan xaadirka ah, baytariyada lithium ion waxay door muhiim ah ka ciyaareen nolosha dadka, laakiin wali waxaa jira dhibaatooyin xaga tignoolajiyada baytariyada lithium. Sababta ugu weyn ayaa ah in elektrolytka loo isticmaalo baytariyada lithium waa lithium hexafluorophosphate, kaas oo aad u xasaasi u ah qoyaanka oo leh heerkul sare. Deganaansho la'aanta iyo alaabada kala-go'a ayaa ah kuwa udub-dhexaad u ah walxaha korantada, taasoo keentay waxqabadka badbaadada lithium ee baytariyada lithium. Isla mar ahaantaana, LiPF6 waxay sidoo kale leedahay dhibaatooyin ay ka mid yihiin milanka liidata iyo dhaqdhaqaaqa hooseeya ee jawiga heerkulka hooseeya, kaas oo aan buuxin karin isticmaalka baytariyada lithium. Sidaa darteed, aad bay muhiim u tahay in la horumariyo cusbada lithium ee elektrolytka oo leh waxqabad aad u fiican.
Ilaa hadda, hay'adaha cilmi-baaristu waxay soo saareen noocyo kala duwan oo cusbo lithium ah oo elektrolyt ah, kuwa badan oo wakiil ka ah waa lithium tetrafluoroborate iyo lithium bis-oxalate borate. Waxaa ka mid ah, lithium bis-oxalate borate ma fududa in la dumiyo heerkulka sare, dareen la'aanta qoyaanka, habka fududaynta, maya waxay leedahay faa'iidooyinka wasakhda, xasiloonida elektiroonigga ah, daaqad ballaaran, iyo awoodda si loo sameeyo filim wanaagsan oo SEI ah oo ku saabsan dusha sare ee electrode taban, laakiin milanka hoose ee electrolyte ee dareerayaasha carbonate toosan keenaysaa in ay conductivity hooseeyo, gaar ahaan ay heerkulka hooseeyo. Cilmi baaris ka dib, waxaa la ogaaday in lithium tetrafluoroborate ay leedahay milan weyn oo ku jira dareeraha karbohaydrayt sababtoo ah cabbirkeeda molecular yar, taas oo si wax ku ool ah u wanaajin karta waxqabadka heerkulka hooseeya ee baytariyada lithium, laakiin ma samayn karto filimka SEI ee dusha sare ee electrode xun. . Lithium difluorooxalate cusbada electrolyte lithium difluorooxalate borate, sida ay sifooyinka qaab-dhismeedka, lithium difluorooxalate borate isku daraa faa'iidooyinka lithium tetrafluoroborate iyo lithium bis-oxalate borate ee qaab-dhismeedka iyo waxqabadka, ma aha oo kaliya in dareerayaasha carbonate toosan. Isla mar ahaantaana, waxay hoos u dhigi kartaa viscosity ee elektrolytka iyo kordhinta conductivity, taas oo sii wanaajinaya waxqabadka heerkulka hooseeya iyo heerka waxqabadka baytariyada lithium ion. Lithium difluorooxalate borate waxa kale oo ay samayn kartaa lakabka guryaha dhisme ee dusha sare ee electrode taban sida lithium bisoxalate borate. Filimka SEI ee wanaagsan ayaa ka weyn.
Vinyl sulfate, oo ah wax lagu daro milix kale oo aan lithium ah, sidoo kale waa wax lagu daro filimka SEI, kaas oo xakameyn kara hoos u dhaca awoodda bilowga ah ee batteriga, kordhinta awoodda dheecaanka bilowga ah, hoos u dhigida ballaarinta batteriga ka dib marka lagu dhejiyo heerkul sare. , oo wanaajinaya waxqabadka lacag-bixinta ee batteriga, taas oo ah, tirada wareegyada. . Taas oo kordhinaysa dulqaadka sare ee batteriga iyo sii dheeraynta nolosha adeegga batteriga. Sidaa darteed, rajada horumarinta ee waxyaabaha lagu daro korantada ayaa sii kordhaya dareenka, iyo baahida suuqa ayaa sii kordheysa.
Marka loo eego "Buugga Tilmaamaha Hagaajinta Habaynta Qaab-dhismeedka Warshadaha (2019 Edition)", waxyaabaha lagu daro korantada ee mashruucani waxay la jaan qaadayaan qaybta koowaad ee qaybta dhiirigelinta, Qodobka 5 (tamar cusub), dhibic 16 "horumarinta iyo adeegsiga tamarta cusub ee mobilada teknoolajiyada", Qodobka 11 (warshadaha kiimikada petrochemical) dhibic 12 "la hagaajiyey, koollada biyaha ku salaysan iyo koollada cusub ee kulul kulul, nuuga biyaha deegaanka saaxiibtinimo, wakiilada biyaha daaweynta, shaandho molecular mercury adag, meerkuri-free iyo kuwo kale oo waxtar leh oo deegaanka saaxiibtinimo iyo wax lagu daro, nanomaterials, Horumarinta iyo soo saarista qalabka xuubka functional, reagents ultra-nadiif ah oo sare-nadiifinta, photoresists, gaaska elektarooniga ah, qalabka crystal dareere-waxqabadka sare iyo kiimikooyin kale oo cusub oo cusub; Marka loo eego dib-u-eegista iyo falanqaynta dukumentiyada siyaasadda warshadaha ee qaranka iyo kuwa maxalliga ah sida "Ogaysiis ku saabsan Tilmaamaha Liiska Xun ee Horumarinta Dhaqaalaha Suunka (Dhaqanka Tijaabada)" ( Dukumentiga Xafiiska Changjiang No. 89), waxaa la go'aamiyay in mashruucani aanu ahayn Mashruuc horumarineed oo xaddidan ama mamnuuc ah.
Tamarta la isticmaalo marka uu mashruucu gaadho awooda wax soo saarka waxa ka mid ah koronto, uumi iyo biyo. Waqtigan xaadirka ah, mashruucu wuxuu qaadanayaa tignoolajiyada wax soo saarka sare ee warshadaha iyo qalabka, wuxuuna qaatay tallaabooyin kala duwan oo lagu badbaadinayo tamarta. Ka dib markii la isticmaalo, dhammaan tilmaamayaasha isticmaalka tamarta waxay gaareen heerkii ugu sarreeyay ee isla warshadaha Shiinaha, waxayna la jaan qaadayaan heerka qaran iyo warshadaha kaydinta tamarta, heerarka kormeerka tamarta iyo qalabka. Heerka hawlgalka dhaqaalaha; Ilaa inta uu mashruucu fulinayo tilmaamayaasha waxtarka tamarta kala duwan, tilmaamayaasha isticmaalka tamarta 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 loo eego isticmaalka tamarta macquulka ah. Iyadoo taas lagu salaynayo, waxaa la go'aamiyay in mashruucu uusan ku lug lahayn ka faa'iidaysiga kheyraadka on-line.
Miisaanka naqshadeynta mashruuca waa: lithium difluorooxalate borate 200t / a, kaas oo 200t / a lithium tetrafluoroborate loo isticmaalo sida alaabta ceeriin ee lithium difluorooxalate alaabta borate, iyada oo aan shaqada post-processing, laakiin waxa kale oo la soo saari karaa sida alaabta la dhammeeyey. si gooni ah iyadoo loo eegayo baahida suuqa.
