1. Magawo ogwiritsira ntchito anode ya batri ya Lithium:
Pakadali pano, zinthu zogulitsidwa za anode makamaka ndi graphite yachilengedwe ndi graphite yopangira. Needle coke ndi yosavuta kupangidwa kukhala graphit ndipo ndi mtundu wa zinthu zopangira graphite zapamwamba kwambiri. Pambuyo pa graphitization, imakhala ndi kapangidwe kabwino ka fibrous komanso kapangidwe kabwino ka graphite microcrystalline. Poyang'ana mbali yayitali ya tinthu tating'onoting'ono, ili ndi ubwino wamagetsi abwino ndi kutentha komanso coefficient yaying'ono yokulitsa kutentha. Needle coke imaphwanyidwa, kugawidwa m'magulu, kupangidwa, kuphwanyidwa, ndi kupangidwa kuti ipange zinthu zopangira graphite, zomwe zimakhala ndi crystallinity yambiri komanso graphitization, ndipo zili pafupi ndi kapangidwe kabwino ka graphite.
Makampani atsopano a magalimoto amphamvu apita patsogolo mofulumira m'zaka zaposachedwa. Kuyambira Januwale mpaka Seputembala 2022, mphamvu zonse za mabatire amagetsi m'dziko langa ndi 372GWh, kuwonjezeka kwa chaka ndi chaka kwa 176%. Bungwe la Magalimoto la China likuneneratu kuti kugulitsa magalimoto amagetsi kudzafika pa 5.5 miliyoni mu 2022, ndipo kuchuluka kwa magalimoto amagetsi kudzapitirira 5.5 miliyoni chaka chonse. 20%. Motsogozedwa ndi "mzere wofiira woletsa kuyaka" wapadziko lonse lapansi ndi mfundo zapakhomo za "zolinga ziwiri za kaboni", kufunikira kwa mabatire a lithiamu padziko lonse lapansi kukuyembekezeka kufika pa 3,008GWh mu 2025, ndipo kufunikira kwa needlecoke kudzafika pa matani 4.04 miliyoni.
2. Minda yogwiritsira ntchito ma electrode a grafiti:
Needle coke ndi chinthu chapamwamba kwambiri chopangira ma electrode a graphite amphamvu kwambiri/amphamvu kwambiri. Mawonekedwe ake ali ndi kapangidwe ka ulusi wopangidwa bwino komanso chiŵerengero chachikulu cha kutalika kwa tinthu tating'onoting'ono. Pakuumba kwa extrusion, mzere wautali wa tinthu tating'onoting'ono tambiri umayikidwa motsatira njira yotulutsira. . Kugwiritsa ntchito needle coke popanga ma electrode a graphite amphamvu kwambiri/amphamvu kwambiri kuli ndi ubwino wa kukana kochepa, kuchulukitsa kutentha pang'ono, kukana kutentha kwambiri, kugwiritsa ntchito ma electrode ochepa komanso kuchuluka kwa mphamvu yovomerezeka. Ma needle coke okhala ndi malasha ndi mafuta ali ndi makhalidwe awoawo pakugwira ntchito. Poyerekeza magwiridwe antchito a singano, kuwonjezera pa kuchuluka kwenikweni, kuchuluka kwa tap, kukana kwa ufa, kuchuluka kwa phulusa, kuchuluka kwa sulfure, kuchuluka kwa nayitrogeni, Kuphatikiza pa kuyerekeza zizindikiro za magwiridwe antchito wamba monga chiŵerengero cha mbali ndi kugawa kwa tinthu tating'onoting'ono, chisamaliro chiyeneranso kuperekedwa ku kuchuluka kwa kutentha, kukana, mphamvu yokakamiza, kuchuluka kwakukulu, kuchuluka kwenikweni, kukula kwakukulu, anisotropy, mkhalidwe wosaletseka ndi Kusanthula ndi kuwunika kwa zizindikiro za makhalidwe monga deta yowonjezereka mu mkhalidwe woletsedwa, kuchuluka kwa kutentha panthawi yokulitsa ndi kufupika, ndi zina zotero. Zizindikiro za makhalidwe awa ndizofunikira kwambiri kusintha magawo a njira popanga ma electrode a graphite ndikuwongolera magwiridwe antchito a ma electrode a graphite. Ponseponse, magwiridwe antchito a singano yochokera ku mafuta ndi apamwamba pang'ono kuposa a singano yochokera ku malasha.
Makampani akunja a kaboni nthawi zambiri amasankha mafuta abwino kwambiri a singano coke ngati zinthu zopangira zazikulu zopangira ma electrode akuluakulu a UHP ndi HP graphite. Makampani a kaboni aku Japan amagwiritsanso ntchito singano coke yochokera ku malasha ngati zinthu zopangira, koma kokha popanga ma electrode a graphite okhala ndi zofunikira pansi pa Φ600mm. Ngakhale kuti kupanga kwa singano coke m'dziko langa kwachedwa kuposa kwa makampani akunja, kwakula mofulumira m'zaka zaposachedwa ndipo kwayamba kukula. Pakadali pano, ma electrode a graphite amphamvu kwambiri m'dziko langa makamaka ndi singano coke yochokera ku malasha. Ponena za kupanga konse, mayunitsi opanga singano coke m'nyumba amatha kukwaniritsa zosowa za makampani a kaboni kuti apange ma electrode amphamvu kwambiri a graphite a singano coke. Komabe, pali kusiyana kwina poyerekeza ndi makampani akunja pa mtundu wa singano coke. Zipangizo zazikulu za graphite electrode yochokera ku ultra-high-power zimadalirabe singano coke yochokera kunja, makamaka ma electrode a graphite amphamvu kwambiri omwe amatumizidwa kunja. Singano coke ngati zinthu zopangira.
Mu 2021, kupanga zitsulo zapakhomo kudzakhala matani 1.037 biliyoni, omwe kupanga zitsulo zapa ng'anjo yamagetsi kumakhala kochepera 10%. Unduna wa Zamalonda ndi Ukadaulo wa Chidziwitso ukukonzekera limodzi kukweza kuchuluka kwa kupanga zitsulo zapa ng'anjo yamagetsi kufika pa 15% mu 2025. Bungwe la National Iron and Steel Association likuneneratu kuti lidzafika pa 30% mu 2050. Lidzafika pa 60% mu 2060. Kuonjezera chiŵerengero cha kupanga zitsulo zapa ng'anjo yamagetsi kudzalimbikitsa mwachindunji kufunikira kwa ma electrode a graphite, komanso, kufunikira kwa needlecoke.
