ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Soláthraí Stáisiún Cumhachta Inaistrithe

Fosfooraska birta ee Lithium wuxuu u jiraa qaab fosfateed lithium macdanta dabiiciga ah, wuxuu leeyahay qaab dhismeed olivine ah oo nidaamsan. Lithium fosfat fosfat caanaha kimikalka molecular waa: LIMPO4, halkaas oo lithium waa togan; birta dhexe ee birta waa qiimo wanaagsan; Fosfooraska waa saddex-qiimo taban, oo inta badan loo isticmaalo sida batari lithium walxo wanaagsan. Codsiga baytariyada fosfateed ee birta lithium waa: Qalabka kaydinta tamarta, qalabka korontada, baabuurta korontada fudud, baabuurta waaweyn ee korontada, qalabka yar yar iyo awoodda mobile, oo ay ku jiraan lithium iron fosfateed oo leh tamarta cusub ee baabuurta korontada 45% ee tirada guud ee fosfit.

Marka labaad, lithium birta fosfooraska sida walxaha lithium electrode marka la barbar dhigo qalabka kale ee lithium batariyada wanaagsan, qaab dhismeedka olivine waa ammaan badan, deegaanka saaxiibtinimo, raqiis, muddada dheer, waxqabadka heerkulka sare, iwm. Waxqabadka badbaadada waa furaha PO adag ee kiristaalo-fosfateed-sare ah, way adagtahay in la dumiyo, mana noqon doonto qaab dhismeed burburay ama dhalin doona oksaydhyo xooggan inta lagu jiro xad-dhaafka iyo heerkulka sare.

Nolosha wareegga nolosha batteriga-asiidh-ashitada dheer ee wareegga nolosha waxay ku dhowdahay 300 jeer, nolosha adeeggu waa inta u dhaxaysa 1 iyo 1.5 sano. Iyo tirada baytari fosfateed birta lithium gaari kartaa in ka badan 2,000, aragti ahaan isticmaalka nolosha 7-8 sano.

Heerkulka sare ee heerkulka sare waa heerkulka ugu sarreeya ee fosfateet-free birta ilaa 350 ° C ilaa 500 ° C, halka lithium manganate iyo lithium cobaltate ay tahay kaliya 200 ° C. bay&39;ada u saaxiibka ah baytari fosfateed lithium birta guud ahaan waxaa loo arkaa in aanay ku jirin biraha culus iyo biraha dhif ah, aan sun, aan wasakhayn, waa baytari deegaanka cagaaran buuxda. Habka dallaca iyo dheecaanka ee fosfooraska birta lithium sida maaddada electrode togan waa ka duwan yahay qalabka kale ee caadiga ah, iyo dallaca iyo dheecaanka electrochemical ka tarjumaysaa labada weji ee fosfooraska birta lithium, lacag iyo falcelinta dheecaan waa sida soo socota: Dallacaadda Dallacaadda: Dareen, Li + From LifePO4, Fe2 + laga badiyay electron galay FE3 +; markii la sii daayo, Li + wuxuu ku dhexjiraa fosfit bir ah LifePo4.

Isbeddelka Li + wuxuu ku dhacaa interface Lifepo4 / Fepo4, sidaas darteed dallacaadda iyo qulqulka qulqulka waa mid aad u fidsan, suurtogalnimada sidoo kale waa mid deggan, oo ku habboon qalabka elektiroonigga ah. Saddexaad, diyaarinta phosphate iron lithium diyaarinta maaddooyinka leh lithium birta fosfateed. Qaar ka mid ah ilaha lithium ee caadiga ah, isha birta, isha kaarboon, iyo isha fosfooraska waa sida soo socota: Diyaarinta budada fosfateed ee birta lithium waxay saameyn kartaa waxqabadkeeda sida walxo togan.

Waxaa jira habab badan oo loogu talagalay diyaarinta fosfooraska birta ee lithium, sida heerkulka sare ee falcelinta wejiga adag, habka dhimista kulaylka kaarboon, iyo habka hydrothermal unminerated, buufin kulaylka xal, Sol - habka gel, habka guud ee roobab, iwm. 1. Heerkulka sare ee falcelinta wejiga adag ee heerkul sare Habka falcelinta wejiga adag waa in la diyaariyo fosfateta birta lithium waa horumarka ugu bislaaday ee horumarka hadda jira iyo habka ugu isticmaalka badan.

Ka dib isha birta, isha lithium, isha fosfooraska waxaa lagu qasi karaa mitir kiimikaad ka badan isku dhafan isku dhafan, jawi aan firfircooneyn, marka hore 5 ilaa 10 saacadood oo heerkul hoose ah (300 ~ 350 ° C), sidaas darteed alaabta ceeriin ayaa marka hore la gooyaa, ka dibna heerkul sare (600 ~ 800 ° C) Sintering 10 ~ 20h fosfat olith. Heerkulka sare ee habka adag ee habka fosfooraska lithium waa mid sahlan, xaaladaha diyaarinta waa sahlan tahay in la xakameeyo, khasaaruhu waa in cabbirka crystal uu yahay mid weyn, dhexroorka qaybtu ma fududa in la xakameeyo, qaybinta waa mid aan sinnayn, qaabka sidoo kale waa mid aan caadi ahayn, kala duwanaanta alaabta ayaa liidata. 2.

Habka dhimista kulaylka Carbonatic habka dhimista kulaylka kaarboon waa in lagu daro ilaha kaarboon ( istaarijka, sucrose, iwm) ee isku dhafka alaabta ceeriin, sida caadiga ah loo isticmaalo si wadajir ah wejiga adag heerkulka sare, iyo isha carbon yarayn kartaa Fe3 + in calcination heerkulka sare ee Fe2 +, Ka fogow falcelinta inta lagu guda jiro falcelinta si ay u noqdaan Fe3 +, si ay habka iskudubarid waa ka badan oo macquul ah, laakiin waqti ka falcelin waa muddo dheer. 3.

Buufin pyrolysis xal kulaylka buufin waa hab wax ku ool ah oo lagu helo cabbirka qayb isku mid ah iyo qaabka caadiga ah ee budada fosfateed birta lithium. Hordhac waa iniin ka mid ah reactor 450 ilaa 650 ° C leh gaaska side, iyo lithium birta fosfateed la helay ka dib falcelinta heerkulka sare. Spheroid spherical spherical ceeryaamo horudhac ah oo lagu diyaariyey pyrolysis buufin ah ayaa sarreeya, qaybinta qaybinta qaybtuna waa lebis.

Ka dib falcelinta heerkulka sare, pneumophosphate ayaa la helaa. Fosfooraska birta ee lithium waxay ku habboon tahay kordhinta aagga dusha sare ee walxaha, kordhinta tamarta saamiga mugga ee walxaha. 4.

Habka kuleylinta biyuhu waa habka isku dhafka dareeraha, waxaa loola jeedaa fal-celinta kiimikaad ee weelka cadaadiska xiran ee weelka cadaadiska xiran, waxaana kiimiko ahaan uga falceliyaa walxaha ceeriin, lagu dhaqo sifeyn, qallajin ka dib qallajinta. Fosfooraska birta ee lithium waxaa la heli karaa ka dib marka heerkulka sare la qaboojiyo. Diyaarinta ferrite ee habka hydrothermal waxay leedahay faa&39;iidooyinka xakamaynta sahlan ee qaabka crystalline iyo xajmiga walxaha, celceliska dhexroorka qayb ka mid ah, dhexroorka qayb yar, habka fudud, laakiin waxay u baahan tahay heerkul sare iyo qalabka cadaadiska sare, kharashka sare, habka adag.

Marka lagu daro habka kor ku xusan, waxaa jira habka roobka ee caadiga ah, habka sol-gel, habka dhimista oksaydhka, habka qalajinta emulsified, iyo habka mikrowave. 4. Soo koobid In kasta oo habka diyaarinta ee fosfooraska birta lithium uu aad uga badan yahay, marka laga reebo heerkulka sare habka falcelinta wejiga adag, inta badan heerka cilmi shaybaarka.

Iyada oo qoto dheer oo joogto ah ee diyaarinta fosfooraska iyo wax ka beddelka, xawaaraha warshadaynta ee fosfatka ferrite si joogto ah ayaa loo dedejiyaa. Si aad u ogaato horumarkii u dambeeyay ee baytariyada birta-ion-ka ee lithium, fadlan iska diiwaan geli Seminaarka Tijaabada Qalabka Diyaarinta Walxaha Tamarta iyo Tijaabada Oktoobar 16-17! Waqtigaas, Professor, Professor, Hu Guorong, Central South University, ayaa wadaagi doona warbixinta "Lithium-Ion Battery Positive Code Material Lithium Lithium Lithium Industrialization". Ku-xigeenka Agaasimaha Machadka Metallurgy iyo Deegaanka, Jaamacadda Bartamaha Koonfurta, Agaasime kuxigeenka Machadka Teknolojiyadda, Waaxda Sare ee Battery, Waaxda Injineerinka, Shiinaha, Shiinaha Chemistry iyo Ururka Awoodda Jirka, Shiinaha Ururka Batroolka Lithium, Guddiga Bixinta Awoodda Caalamiga ah, Guddiga Isgaarsiinta Battery Lithium.

Inta badan ku hawlan aragtida iyo codsiga korantada kiimikaad, agabka tamarta iyo dhinacyo kale, waxayna ku guulaysteen natiijooyin soo ifbaxaya horumarinta iyo warshadaynta baytariyada lithium-ion ee qalabka elektiroonigga ah. Qabo oo ka qayb in ka badan 20 heer qaran iyo heer gobol mashruuc cilmi cilmi sayniska, oo ay ku jiraan mashruuc gaar ah oo ka mid ah warshadaha waaweyn ee Horumarinta Qaranka iyo Guddiga Dib-u-habaynta, mid ka mid ah Waaxda Sayniska iyo Teknolojiyadda Qaranka ee 863, ayaa mas&39;uul ka ah sayniska iyo teknoolajiyada qaranka mashruuca mashruuca taageero, a alaabta qorshaha qorshooyin qaran iyo mashaariic badan oo muhiim ah oo sayniska iyo teknoolajiyada ee Gobolka Hunan. Natiijooyin muuqda ayaa lagu gaadhay warshadaynta batariyada lithium-ion ee qalabka elektiroonigga togan, oo si guul leh loo xaqiijiyo noolaha lithium cobalt, lithium manganate iyo phosphate iron lithium.

Ku saabsan 2017 Tamarta Diyaarinta Qalabka Granular iyo Seminar Tijaabada Tijaabada Tijaabada Kulankani waxa uu ujeedadiisu tahay in la bixiyo dhufto ee isgaarsiinta ee culimada ku habboon gudaha iyo dibadda, in codsiga ee granules tamarta, xoojinta macluumaadka warshadaha, batari lithium, capacitor, unugyada shidaalka , Korantada gaadhiga batari horumarka samaynta tabaruc.
