1. Libaka tsa ts'ebeliso ea betri ea lithium anode:
Hona joale, lisebelisoa tsa anode tse rekisoang haholo-holo ke graphite ea tlhaho le graphite ea maiketsetso. Nale coke e bonolo ho etsoa graphitized 'me ke mofuta oa lisebelisoa tse tala tsa graphite tsa boleng bo holimo. Kamora graphitization, e na le sebopeho se hlakileng sa fibrous le sebopeho se setle sa graphite microcrystalline. Ka tataiso ea axis e telele ea likaroloana, e na le melemo ea motlakase o motle le motlakase oa mocheso le coefficient e nyenyane ea ho atolosa mocheso. Coke ea nale e sithabelitsoe, e arotsoe, e bōpehile, e granulated, 'me e entsoe ka graphite ho fumana lisebelisoa tsa maiketsetso tsa graphite, tse nang le tekanyo e phahameng ea crystallinity le graphitization,' me e haufi le mohaho o phethahetseng oa graphite.
Indasteri e ncha ea likoloi tsa matla e tsoetse pele ka potlako lilemong tsa morao tjena. Ho tloha ka Pherekhong ho isa Loetse 2022, tlhahiso e akaretsang ea libeteri tsa motlakase naheng ea heso ke 372GWh, keketseho ea selemo le selemo ea 176%. Mokhatlo oa China Automobile Association o bolela esale pele hore thekiso e felletseng ea likoloi tsa motlakase e tla fihla ho limilione tse 5.5 ka 2022, mme sekhahla sa ho kenella ha likoloi tsa motlakase ho pholletsa le selemo se tla feta limilione tse 5.5. 20%. E susumetsoa ke "mohala o mofubelu oa thibelo ea mollo" le leano la lehae la "lipheo tse peli tsa carbon", tlhokahalo ea lefats'e ea libeteri tsa lithium e lebelletsoe ho fihla ho 3,008GWh ka 2025, mme tlhoko ea nale e tla fihla ho lithane tse limilione tse 4.04
2. Libaka tsa kopo ea li-electrode tsa graphite:
Needle coke ke thepa ea boleng bo holimo bakeng sa ho etsa li-electrode tsa graphite tse phahameng / tse phahameng haholo. Ponahalo ea eona e na le sebopeho se entsoeng hantle sa fibrous le tekanyo e kholo ea bolelele ba likaroloana. Nakong ea ho bōptjoa ha extrusion, sebaka se selelele sa likaroloana tse ngata se hlophisitsoe hammoho le tataiso ea extrusion. . Tšebeliso ea lisebelisoa tsa nale ho hlahisa li-electrode tsa graphite tse phahameng / tse phahameng haholo li na le melemo ea ho hanyetsa ka tlaase, ho fokotsa mocheso o fokolang oa mocheso, ho hanyetsa mocheso o matla oa mocheso, ho sebelisoa ha li-electrode tse tlaase le matla a phahameng a amohelehang a hona joale. Li-cokes tsa nale tse entsoeng ka mashala le oli li na le litšobotsi tsa tsona ts'ebetsong. Papisong ea ts'ebetso ea nale ea coke, ho phaella ho boima ba 'nete, boima ba pompong, ho hanyetsa phofo, molora, dikahare tsa sebabole, naetrojene, Ho phaella ho papisong ea matšoao a tloaelehileng a ts'ebetso a kang aspect ratio le kabo ea boholo ba likaroloana, tlhokomelo e lokela ho etsoa. e boetse e lefshoa ho coefficient ea ho atolosa mocheso, resistivity, matla a khatello, bongata ba bongata, boima ba 'nete, katoloso ea bongata, anisotropy, boemo bo sa thibeloang le Tlhahlobo le tlhahlobo ea matšoao a kang a ho atolosa sebakeng se thibetsoeng, mocheso oa mocheso nakong ea ho atolosa le ho fokotseha, joalo-joalo matšoao ana a tšobotsi a bohlokoa haholo ho fetola mekhoa ea ts'ebetso ts'ebetsong ea tlhahiso ea li-electrode tsa graphite le ho laola ts'ebetso ea li-electrode tsa graphite. Ka kakaretso, ts'ebetso ea nale e thehiloeng ka oli e phahame hanyane ho feta ea coke ea nale e entsoeng ka mashala.
Likhoebo tsa khabone tsa kantle ho naha hangata li khetha li-electrode tsa oli ea boleng bo holimo e le thepa e tala ea ho hlahisa li-electrode tse kholo tsa UHP le HP graphite. Likhoebo tsa k'habone tsa Japane le tsona li sebelisa coke ea nale e entsoeng ka mashala e le lisebelisoa tse tala, empa feela bakeng sa tlhahiso ea li-electrode tsa graphite tse nang le lintlha tse ka tlase ho Φ600mm. Le hoja tlhahiso ea liindasteri ea needle coke naheng ea heso e se e le morao ho feta ea lik'hamphani tsa linaha tse ling, e tsoetse pele ka potlako lilemong tsa morao tjena 'me e qalile ho ba teng. Hajoale, li-electrode tsa graphite tsa naha ea heso tse matla haholo ke coke ea nale e entsoeng ka mashala. Mabapi le tlhahiso e felletseng, likarolo tsa tlhahiso ea nale ea lapeng li ka fihlela litlhoko tsa likhoebo tsa k'habone ho hlahisa li-electrode tsa graphite tse phahameng / tsa matla bakeng sa coke ea nale. Leha ho le joalo, ho ntse ho na le lekhalo le itseng ha le bapisoa le lik'hamphani tsa kantle ho naha ka boleng ba nale. Lisebelisoa tse tala tsa graphite electrode tse kholo tsa matla a maholo li ntse li itšetlehile ka coke ea nale e tsoang linaheng tse ling, haholo-holo li-electrode tsa graphite tse phahameng / tse nang le matla a mangata li romeloa linaheng tse ling. Nale coke e le thepa e tala.
Ka 2021, tlhahiso ea tšepe ea malapeng e tla ba lithane tse limilione tse likete tse 1.037, tseo ho tsona ho etsoa tšepe ea sebōpi sa motlakase ka tlase ho 10%. Lekala la Indasteri le Theknoloji ea Boitsebiso ka kopanelo le rera ho eketsa karolo ea ho etsa tšepe ea sebōpi sa motlakase ho feta 15% ka 2025. Mokhatlo oa Sechaba oa Iron le Steel Association o bolela esale pele hore o tla fihla 30% ka 2050. E tla fihla 60% ka 2060. Ho eketseha. karo-karolelano ea tšepe ea libopi tsa motlakase e tla khanna ka ho toba tlhokahalo ea li-electrode tsa graphite, 'me ho hlakile, tlhokahalo ea nale coke.
