1. Minda yekushandisa anode yebhatiri reLithium:
Parizvino, zvinhu zveanode zvinotengeswa zvinonyanya kuve graphite yechisikigo uye graphite yekugadzira. Needle coke iri nyore kugadzirwa graphit uye imhando yezvigadzirwa zvemhando yepamusoro zve graphite yekugadzira. Mushure me graphitization, ine chimiro chakajeka che fibrous uye chimiro chakanaka che graphite microcrystalline. Munzira ye axis refu yezvimedu, ine zvakanakira zve conductivity yakanaka yemagetsi nekupisa uye thermal expansion coefficient diki. Needle coke inopwanywa, inorongwa, inoumbwa, inochekwa, uye inogadziriswa graphit kuti iwane zvigadzirwa zve graphite yekugadzira, ine mwero wepamusoro we crystallinity uye graphitization, uye iri pedyo nechimiro chakakwana che graphite layered.
Indasitiri itsva yemotokari dzemagetsi yakawedzera nekukurumidza mumakore achangopfuura. Kubva muna Ndira kusvika Gunyana 2022, huwandu hwemabhatiri emagetsi munyika yangu hunosvika 372GWh, kuwedzera kwegore negore kwe176%. Sangano reChina Automobile Association rinofanotaura kuti huwandu hwese hwekutengesa mota dzemagetsi huchasvika mamiriyoni 5.5 muna 2022, uye huwandu hwemotokari dzemagetsi dzinopinda mugore rose huchapfuura mamiriyoni 5.5. 20%. Nekukurudzirwa ne "mutsara mutsvuku wekurambidza kupisa" wepasi rose uye mutemo we "dual carbon goals", kudiwa kwemabhatiri e lithium pasi rose kunotarisirwa kusvika 3,008GWh muna 2025, uye kudiwa kwe needle coke kuchasvika mamiriyoni 4.04 ematani.
2. Minda yekushandisa graphite electrode:
Needle coke chinhu chemhando yepamusoro chekugadzira ma electrode e graphite ane simba guru/rakanyanya. Chitarisiko chayo chine chimiro che fibrous texture chakagadzirwa zvakanaka uye chiyero chikuru chehurefu nehupamhi hwe particle. Munguva yekuumbwa kwe extrusion, axis refu yezvikamu zvakawanda inorongwa nenzira yekubuda. . Kushandiswa kwe needle coke kugadzira ma electrode e graphite ane simba guru/rakanyanya kune zvakanakira zve resistivity yakaderera, low thermal expansion coefficient yakaderera, strong thermal shock resistance, low electrode use uye high permitble current density. Ma needle coke ane hunhu hwawo mukushanda. Mukufananidza mashandiro e needle coke, pamusoro pehuwandu hwechokwadi, huwandu hwetap density, hupfu hunodzivirira, huwandu hwedota, huwandu hwesarufa, huwandu hwenitrogen, Pamusoro pekufananidza zviratidzo zvemaitiro zvakajairika zvakaita se aspect ratio uye kugoverwa kwehukuru hweparticle, kutarisisa kunofanirwawo kubhadharwa kune thermal expansion coefficient, resistivity, compressive strength, bulk density, true density, bulk expansion, anisotropy, uninhibited state uye Kuongorora uye kuongorora zviratidzo zvecharacteristic senge expansion data mumamiriro akadziviswa, tembiricha range panguva yekuwedzera uye contraction, nezvimwewo. Zviratidzo izvi zvecharacteristic zvakakosha zvikuru kugadzirisa ma process parameters mukugadzirwa kwema graphite electrodes uye kudzora mashandiro ema graphite electrodes. Pamusoro pezvose, mashandiro e needle coke akavakirwa pamafuta akakwira zvishoma pane e needle coke akavakirwa pamarasha.
Makambani ekunze anowanzo sarudza ma "needle coke" emafuta emhando yepamusoro sezvinhu zvikuru zvekugadzira ma "electrodes" makuru eUHP neHP graphite. Makambani eJapan anogadzira "carbon" anoshandisawo mamwe ma "needle coke" emarasha sezvinhu zvekugadzira, asi chete pakugadzira ma "electrodes" e "graphite" ane zvirevo zviri pasi pe Φ600mm. Kunyangwe kugadzirwa kwe "needle coke" mumaindasitiri munyika yangu kwave kunonoka kupfuura kwemakambani ekunze, kwave kukura nekukurumidza mumakore achangopfuura uye kwatanga kuoneka. Parizvino, ma "electrode aggregates" e "grafiti" emunyika yangu anonyanya kuve ma "needle coke" emarasha. Panyaya yekugadzirwa kwese, ma "needle coke" emumba anogona kusangana nezvinodiwa nemabhizinesi e "carbon" kuti agadzire ma "electrodes" e "grafiti" e "high-power" e "needle coke". Zvisinei, kuchine musiyano wakakura kana tichienzanisa nemakambani ekunze mumhando ye "needle coke". Zvinhu zvikuru zve "grafiti coke" zve "large-high-power" zvichiri kuvimba ne "needle coke" inopinzwa munyika, kunyanya ma "joints" e "grafiti electrode" e "high-power" anopinzwa munyika. "Needle coke" sezvinhu zvekugadzira.
Muna 2021, kugadzirwa kwesimbi yemuno kuchave matani mabhiriyoni 1.037, ayo ekugadzira simbi yemagetsi muchoto isingasviki 10%. Bazi reIndasitiri neTekinoroji yeRuzivo pamwe chete rinoronga kuwedzera huwandu hwekugadzira simbi yemagetsi muchoto kusvika pamusoro pe15% muna 2025. Sangano reNational Iron and Steel rinofanotaura kuti richasvika 30% muna 2050. Richasvika 60% muna 2060. Kuwedzera chiyero chekugadzira simbi muchoto chemagetsi kuchakurudzira zvakananga kudiwa kwema graphite electrodes, uye zvechokwadi, kudiwa kwe needle coke.
