1. Goobaha codsiga ee bateriga lithium anode:
Waqtigan xaadirka ah, agabka anode-ka la ganacsiyeeyay ayaa inta badan ah garaafyada dabiiciga ah iyo garaafyada macmalka ah. Coke irbadu way fududahay in la sawiro waana nooc ka mid ah agabka garaafiga macmalka ah ee tayada sare leh. Garaafaynta ka dib, waxay leedahay qaab dhismeed fibros ah oo muuqda iyo qaab dhismeedka microcrystalline garaafeed wanaagsan. Jihada dhidibka dheer ee qaybaha, waxay leedahay faa'iidooyinka korantada wanaagsan iyo kulaylka wanaagsan iyo iskudhafka ballaarinta kulaylka yar. Coke irbadu waa la jajabiyaa, la kala saaraa, qaabaysan, granulated, iyo garaafay si loo helo maadada garaafka macmalka ah, kaas oo leh heer sare oo crystallinity iyo garaafayn, wuxuuna ku dhow yahay qaab-dhismeedka garaafiga ee qumman.
Warshadaha cusub ee baabuurta tamarta ayaa si degdeg ah u horumaray sanadihii ugu dambeeyay. Laga bilaabo Jannaayo ilaa Sebtembar 2022, wax soo saarka guud ee baytariyada korantada ee dalkaygu waa 372GWh, korodhka sanadba sanadka ka dambeeya 176%. Ururka Baabuurta ee Shiinaha ayaa saadaaliyay in wadarta iibka baabuurta korantada ay gaari doonto 5.5 milyan sanadka 2022, iyo heerka gelitaanka baabuurta korontada sanadka oo dhan uu kor u dhaafi doono 5.5 milyan. 20% Iyada oo ay saameynayso khadka caalamiga ah ee "khadka cas ee mamnuucidda gubida" iyo siyaasadda gudaha ee "goolasha laba kaarboon", baahida caalamiga ah ee baytariyada lithium ayaa la filayaa inay gaaraan 3,008GWh sanadka 2025, iyo baahida loo qabo coke cirbadu waxay gaari doontaa 4.04 milyan oo tan.
2. Garoomada codsiga graphite electrode:
Coke irbadu waa shay tayo sare leh oo lagu soo saaro koronto garaafyo sare/ultra-sare leh. Muuqaalkeedu wuxuu leeyahay qaab-dhismeed dhogor leh oo si fiican u horumaray iyo saamiga dhererka-ballaadhka qayb weyn. Inta lagu jiro qaabaynta extrusion, dhidibka dheer ee qaybaha badankooda waxaa lagu habeeyaa jihada extrusion. . Isticmaalka coke irbadda si loo soo saaro koronto garaafyada sare / ultra-sare leh waxay leedahay faa'iidooyinka iska caabbinta hooseeya, iskudhafka fidinta kulaylka hooseeya, caabbinta shoogga kulaylka xooggan, isticmaalka korantada hooseeya iyo cufnaanta hadda la oggol yahay ee sarreeya. Cokes-ku-saleysan dhuxusha iyo saliida-ku-saleysan ee cirbadaha waxay leeyihiin sifooyin u gaar ah waxqabadka. Marka la barbardhigo waxqabadka coke cirbadda, marka lagu daro cufnaanta dhabta ah, cufnaanta tuubada, caabbinta budada, content ash, content sulfur, content nitrogen. sidoo kale waxaa lagu bixiyaa isugeynta balaarinta kulaylka, iska caabinta, xoogga cufan, cufnaanta bulk, cufnaanta dhabta ah, ballaarinta bulk, anisotropy, gobolka aan la xakameynin iyo Falanqaynta iyo qiimeynta tilmaamayaasha sifaha sida xogta ballaarinta ee gobolka xaddidan, heerkulka heerkulka inta lagu jiro ballaarinta iyo foosha, iwm. Tilmaamayaashan sifaha ah ayaa aad muhiim u ah si loo hagaajiyo cabbirada habka habka wax soo saarka ee electrodes graphite iyo in la xakameeyo waxqabadka graphite electrodes. Isku soo wada duuboo, waxqabadka kookaha cirbadda saliidda ku salaysan ayaa waxyar ka sarreeya kan kookaha irbadda ee dhuxusha.
Shirkadaha ajnabiga ah ee kaarboonka waxay inta badan doortaan kookaha cirbadda saliidda oo tayadoodu sarreyso inay noqoto alaabta ceeriin ee ugu weyn ee soo saarta UHP iyo HP garaafyada elektiroonigga ah. Shirkadaha kaarboonka ee Japan waxay sidoo kale u isticmaalaan qaar ka mid ah coke irbad dhuxusha ku salaysan sida alaabta ceeriin, laakiin kaliya wax soo saarka ee electrodes graphite oo leh tilmaamo ka hooseeya Φ600mm. In kasta oo wax-soo-saarka wershadaha ee coke-ga irbadda ee dalkaygu uu ka dambeeyo kan shirkadaha shisheeye, haddana si xawli ah ayuu u horumaray sannadihii u dambeeyay oo wuxuu bilaabay inuu qaab yeesho. Waqtigan xaadirka ah, wadarta tamarta sare ee graphite electrode ee wadankeygu waa inta badan coke-ku-saleysan dhuxusha. Marka la eego wadarta wax soo saarka, cutubyada wax soo saarka coke cirbadaha gudaha ayaa asal ahaan dabooli kara baahida shirkadaha kaarboonka si ay u soo saaraan koronto garaafyo sare / ultra awood leh oo loogu talagalay coke irbadda. Si kastaba ha ahaatee, weli waxaa jira farqi gaar ah marka loo eego shirkadaha ajnabiga ah ee tayada coke irbadda. Qalabyada cayriin ee cabbirka aadka u sarreeya ee ultra-sare ee garaafiga ah ayaa wali ku tiirsan kookaha irbadda ee dibedda laga keeno, gaar ahaan kala-goysyada korantada garaafyada ee awoodda sare/awoodda sare leh waa la soo dejiyaa. Irbada coke sida alaabta ceeriin.
Sannadka 2021, wax-soo-saarka birta waddanku wuxuu noqonayaa 1.037 bilyan oo tan, kuwaas oo foornada korontada ku shaqeysata ay ka yar tahay 10%. Wasaaradda Warshadaha iyo Tignoolajiyada ayaa si wada jir ah u qorsheyneysa in ay kordhiso saamiga birta foornada korontada laga sameeyo in ka badan 15% sanadka 2025. Ururka birta iyo birta ee qaranka ayaa saadaaliyay in uu gaari doono 30% sanadka 2050 saamiga steelmaking ee foornooyinka korontada si toos ah u kaxayn doona baahida loo qabo electrodes graphite, iyo dabcan, baahida loo qabo coke irbadda.
