Needle coke ke mofuta oa boleng bo holimo o ntlafalitsoeng ka matla ka thepa ea khabone. Ponahalo ea eona ke porous solid le silevera ea bohlooho le metallic luster. Sebopeho sa eona se na le sebopeho se hlakileng se phallang, se nang le masoba a maholo empa a se makae le sebopeho sa oval hanyenyane. Ke thepa e tala bakeng sa ho hlahisa lihlahisoa tse phahameng tsa carbon tse kang electrode ea matla a phahameng, lisebelisoa tse khethehileng tsa carbon, carbon fiber le lisebelisoa tsa eona tse kopantsoeng.
Ho ea ka lisebelisoa tse fapaneng tse tala, nale coke e ka aroloa ka oli ea nale coke le coke ea nale ea mashala. Nale coke e hlahisoang ke masalla a petroleum ke oli ea nale coke. Nale coke e hlahisoang ho tsoa ho sekontiri sa mashala 'me karoloana ea eona ke letoto la mashala la nale coke.
Li-index tse amang boleng ba nale coke li kenyelletsa boima ba 'nete, sebabole, dikahare tsa naetrojene, taba e sa tsitsang, molora, coefficient ea ho atolosa mocheso, resistivity, vibration density, joalo-joalo Ka lebaka la coefficient e fapaneng ea index, nale coke e ka aroloa ka sehlopha se seholo (sehlopha se setle), sehlopha sa pele le sehlopha sa bobeli.
Phapang ea ts'ebetso lipakeng tsa coke ea nale ea mashala le oli e kenyelletsa lintlha tse latelang.
1. Tlas'a maemo a tšoanang, electrode ea graphite e entsoeng ka oli ea nale ea coke e bonolo ho e bōpa ho feta coke ea nale ea mashala.
2. Ka mor'a ho etsa lihlahisoa tsa graphite, boima le matla a lihlahisoa tsa graphitized tsa oli-series ea nale coke e phahame hanyenyane ho feta ea coke ea nale ea mashala, e bakoang ke ho atolosoa ha letoto la nale ea mashala nakong ea graphitization.
3. Tšebelisong e khethehileng ea electrode ea graphite, sehlahisoa se entsoeng ka graphite sa coke ea nale ea oli se na le coefficient e tlaase ea ho atolosa mocheso.
4. Mabapi le li-index tsa 'mele le tsa lik'hemik'hale tsa electrode ea graphite, khanyetso e khethehileng ea sehlahisoa sa graphitized ea oli ea nale coke e phahame hanyenyane ho feta sehlahisoa sa mashala sa nale ea coke.
5. Ntho ea bohlokoa ka ho fetisisa ke hore mashala a lekanya nale coke e atoloha ha mocheso o fihla ho 1500-2000 ℃ ts'ebetsong ea mocheso o phahameng oa graphitization, kahoo sekhahla sa ho phahama ha mocheso se lokela ho laoloa ka thata, eseng ho phahama ha mocheso ka potlako, ho molemo hore u se ke ua sebelisa letoto la tlhahiso ea graphitization, mashala a lekanya nale coke ka ho eketsa li-additives ho laola katoloso ea eona. Empa ho thata le ho feta ho fumana coke ea nale ea oli.
6. Calcined oli nale coke na le ho feta tse nyenyane tse coke le phatsa boholo bo botle, ha mashala nale coke na le dikahare ka tlaase ho moo le boholo phatsa boholo (35 — 40 limilimithara), e leng ho ka kopana le ditlhoko tsa foromo foromo phatsa boholo, empa e tlisa mathata ho basebelisi.
7. Ho ea ka kenyelletso ea Japane Petroleum Coke Company, ho lumeloa hore ho hlophisoa ha oli ea nale ea coke ho bonolo ho feta coke ea nale ea mashala, kahoo ho bonolo ho laola nako ea ho pheha le ho futhumatsa.
Ho tloha ka holimo, coke ea nale ea oli e na le tse 'nè tse tlaase: matla a tlaase a bohata a fokolang, matla a tlaase, CTE e tlaase, khanyetso e khethehileng, tse peli tsa pele tse tlaase ho lihlahisoa tsa graphite, tse peli tsa ho qetela tse tlaase ho lihlahisoa tsa graphite li ntle. Ka kakaretso, li-index tsa ts'ebetso ea letoto la oli ea nale coke li molemo ho feta letoto la mashala la nale, 'me tlhokahalo ea kopo le eona e feta.
Hajoale, li-electrode tsa graphite ke 'maraka o ka sehloohong oa tlhokeho ea nale, e nkang karolo ea 60% ea kakaretso ea ts'ebeliso ea nale, athe likhoebo tsa li-electrode li na le tlhokahalo e hlakileng ea boleng ba nale, ntle le tlhokahalo ea boleng ba motho. Tlhokahalo ea nale ea lisebelisoa tsa lithium ion battery anode e fapane haholo, 'maraka oa dijithale o phahameng o rata oli e phehiloeng ka coke,' maraka oa betri ea matla o itšetlehile haholo ka coke ka ts'ebetso e phahameng ea litšenyehelo.
Tlhahiso ea li-needle coke e na le moeli o itseng oa tekheniki, ka hona likhoebo tsa lapeng ha li fumanehe hangata. Hona joale, likhoebo tse ka sehloohong tsa tlhahiso ea lihlahisoa tsa nale coke li kenyelletsa: Weifang Fumei New Energy, Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei matla a macha, Shandong Yiwei, Sinopec jinling Petrochemical, Maoming Coolstream production series, Coco-Cool-Cool-Cool-Cool-Cool-Cool-Coo-Entertainment, joalo-joalo.
