Dab tsi yog cov txheej txheem nthuav dav ntawm zhenan graphite electrodes?
Kev tsim cov roj hauv lub roj teeb yog qhov tseem ceeb ua rau roj teeb o. Seb lub roj teeb tsis sib xws, caij tsheb kauj vab, lossis tswj hwm thaum muaj kub, qhov no yuav ua rau muaj kev sib txawv ntawm cov roj. Graphite hluav taws xob yog tsim los ntawm cov roj coke thiab rab koob coke raws li cov ntaub ntawv raw, nrog cov txheej txheem suav nrog, molding, ci, graphitization, thiab machining. Lawv tau siv los ua hluav taws xob ntawm cov hluav taws xob hauv arc rauv taws kom kub thiab yaj scrap hlau. Nyob ntawm lawv cov qauv zoo, lawv tuaj yeem raug cais ua lub zog dav dav, lub zog loj, thiab ultra} lub zog loj.
Graphite electrodes tsuas yog suav nrog plaub hom duab hluav taws xob, oxidation {{} {{{{2} high fais fab graphite hluav taws xob. Graphite cov pas nrig nquag siv los ua cua sov uas muaj cov cua sov hauv siab- kub lub tshuab ziab khaub ncaws, nrog kev ua haujlwm siab tshaj plaws ntawm 3000 degree. Thaum kub siab, lawv nquag siv oxidation thiab tsuas yog siv tau hauv nruab nrab nruab nrab lossis oxidizing cua, tsis suav cov plua plav ib puag ncig. Lawv muaj cov coefficient ntawm thermal expansion, siab thermal conductivity, thiab kev tiv thaiv (8 ~ 13) {17 ·. Lawv txoj kev ua tau zoo dua li ntawm Sic lossis Mosi2 cov pas nrig, thiab lawv yog cua sov-resistant, tiv taus heev heev thiab cua sov, thiab pheej yig. Graphite blocks yog hom hluavtaws hluavtaws, ua los ntawm COKE los ntawm ntau yam kev ua haujlwm.
Feem ntau, yog tias cov duab yog ua kom huv siab los yog siv los ua kom muaj fiber cabro fiber, nws tus nqi nce ntxiv. Nws tau raug pov thawj tias roj teeb o tuaj tshwm sim los ntawm kev rhuav tshem ntawm cov lithium {{1} ion roj teeb electrolyte. Muaj ob qho xwm txheej uas decomposition tshwm sim: ib qho yog vim yog impurities, xws li cov khoom seem hlau, dej, thiab yaj roj; Qhov tod yog vim muaj tsawg electrochemical lub qhov rais ntawm cov electrolyte, ua rau decompose thaum lub sijhawm them. Piv txwv li, cov organic huab cua EC thiab Dec, tom qab radicals tsis zoo, uas yog qhov ua kom muaj oxygen dawb radical, uas yog cov pa oxo}} Lub thickness hloov ntawm roj teeb hluav taws xob cov phiaj xwm ntau yam sib txawv:
(1) Rau txias - rolled electrode daim hlau, tom qab so, cov tuab tuab, cov tuab tuab, cov tuab tuab ua kom nruj dua; Raws li kev ntxhov siab tib yam, ib qho loj dua modulus ntawm cov phau ntawv tau tshwm sim hauv tsawg dua, thaum ziab tuaj yeem ua rau hluav taws xob phaj.
(2) Kev nqus tau ntawm electrolyte los ntawm electrode thiab o ntawm cov khoom electrode tuaj yeem nce cov hluav taws xob thickness.
(3) Thaum lub sijhawm them teeb meem roj teeb, Lithium sib txuas ua kom muaj hluav taws xob nthuav dav vim kev hloov pauv hauv cov lattice tsis sib xws.
Daim ntawv no cov ntsiab lus Cov txheej txheem hloov dua siab tshiab thiab anode nthuav dav hauv lithium {{} ion roj teeb graphite anodes.
Nyob rau hauv lithium - Graphite coin cell, raws li cov electrode maj mam nce raws li Lithium yog intercalated rau hauv graphite. Tus txheej txheem no tuaj yeem faib ua ob peb theem, nrog cov txheej txheem graphite nce hauv cov ntsiab lus lithium (x maj mam nce). Lixc6 muaj nyob rau ntau theem sib txawv; Cov lus 1 teev qee tus yam ntxwv ntawm tus txheej txheem no, qhov twg x sawv cev rau cov pob txha caj qaum hauv Lexc6, thiab D yog interlayer spacing ntawm graphite lattice. Nrog nce lithium intercalation, cov theem hloov ntawm 2h graphite rau LIC12, thiab thaum kawg rau tag nrho cov Lithiaden Lat6 (372 ma theoretical muaj peev xwm / g). Qhov kev hloov pauv no ua rau lub d -} sib txuas kom maj mam nce, ua rau muaj cov hluav taws xob tuab.
