1. Izinkambu ze-anode yebhethri ye-lithium:
Njengamanje, izinto ezithengiswayo ze-anode ikakhulukazi ziyi-graphite yemvelo kanye ne-graphite yokwenziwa. I-needle coke kulula ukwenziwa i-graphitized futhi iwuhlobo lwekhwalithi ephezulu ye-graphite yokwenziwa kwempahla eluhlaza. Ngemuva kwe-graphitization, inesakhiwo esicacile se-fibrous kanye nesakhiwo esihle se-graphite microcrystalline. Ekuqondeni kwe-axis ende yezinhlayiya, inezinzuzo ze-conductivity enhle kagesi kanye ne-thermal kanye ne-coefficient encane yokwandisa ukushisa. I-needle coke iyachotshozwa, ihlukaniswe, ibunjwe, ifakwe i-granulated, futhi yenziwe i-graphite ukuze kutholwe impahla ye-graphite yokwenziwa, enezinga eliphezulu le-crystallinity kanye ne-graphitization, futhi iseduze nesakhiwo esiphelele se-graphite.
Imboni entsha yezimoto zamandla ithuthuke ngokushesha eminyakeni yamuva. Kusukela ngoJanuwari kuya kuSepthemba 2022, ukuphuma okuhlanganisiwe kwamabhethri kagesi ezweni lami kungu-372GWh, okuwukunyuka konyaka ngo-176%. I-China Automobile Association ibikezela ukuthi ukuthengiswa okuphelele kwezimoto zikagesi kuzofinyelela ezigidini ezingu-5.5 ngo-2022, futhi izinga lokungena kwezimoto zikagesi unyaka wonke lizodlula izigidi ezingu-5.5. 20%. Ithonywe "umugqa obomvu wokuvinjelwa komlilo" wamazwe omhlaba kanye nenqubomgomo yasekhaya "yezinhloso zekhabhoni ezimbili", isidingo somhlaba wonke samabhethri e-lithium kulindeleke ukuthi sifinyelele ku-3,008GWh ngo-2025, kanti isidingo senaliti coke sizofinyelela amathani ayizigidi ezi-4.04
2. Izinkambu ze-graphite electrode:
I-needle coke iyimpahla yekhwalithi ephezulu yokukhiqiza ama-electrode amagraphite wamandla aphezulu/aphezulu kakhulu. Ukubukeka kwayo kunokwakheka kwe-fibrous ethuthuke kahle kanye nesilinganiso esikhulu sobude bezinhlayiyana. Ngesikhathi sokubunjwa kwe-extrusion, i-eksisi ende yezinhlayiya eziningi ihlelwa eduze kwesiqondiso se-extrusion. . Ukusetshenziswa kwe-coke yenaliti ukukhiqiza ama-electrode e-graphite aphezulu/aphezulu kunezinzuzo zokungabekezeleli okuphansi, i-coefficient ephansi yokwandisa ukushisa okushisayo, ukumelana nokushaqeka okushisayo okuqinile, ukusetshenziswa okuphansi kwe-electrode kanye nokugcwala okuphezulu okuvunyelwe kwamanje. Ama-coke enaliti asekelwe ngamalahle kanye ne-oyela anezici zawo ekusebenzeni. Uma kuqhathaniswa nokusebenza kwenaliti ye-coke, ngaphezu kokuminyana kweqiniso, ukuminyana kompompi, ukumelana nempuphu, okuqukethwe komlotha, okuqukethwe kwesibabule, okuqukethwe kwe-nitrogen, Ngaphezu kokuqhathanisa izinkomba zokusebenza ezivamile ezifana ne-aspect ratio nokusabalalisa usayizi wezinhlayiyana, ukunakwa kufanele futhi ikhokhwe ku-coefficient yokwandisa okushisayo, ukumelana, amandla okucindezela, ukuminyana kwenqwaba, ukuminyana kweqiniso, ukunwetshwa kwenqwaba, i-anisotropy, isimo esingavinjiwe kanye nokuhlaziywa nokuhlolwa kwezinkomba zesici ezifana nedatha yokunwetshwa esimweni esivinjelwe, izinga lokushisa ngesikhathi sokwanda nokufinyela, njll. Lezi zinkomba zesici zibaluleke kakhulu ukulungisa imingcele yenqubo ekukhiqizeni ama-electrode e-graphite nokulawula ukusebenza kwama-graphite electrode. Sekukonke, ukusebenza kwe-coke yenaliti esekwe ku-oyela kuphakeme kancane kunokwe-coke yenaliti esekwe emalahleni.
Amabhizinisi ekhabhoni yakwamanye amazwe avame ukukhetha icoke yenaliti kawoyela yekhwalithi ephezulu njengento eluhlaza eyinhloko yokukhiqiza ama-electrode amakhulu e-UHP ne-HP graphite. Amabhizinisi ekhabhoni aseJapan nawo asebenzisa i-coke yenaliti esekelwe emalahleni njengezinto zokusetshenziswa, kodwa kuphela ukukhiqiza ama-electrode e-graphite anemininingwane engaphansi kuka-Φ600mm. Nakuba ukukhiqizwa kwezimboni ze-needle coke ezweni lami sekwephuzile kunokwezinkampani zakwamanye amazwe, sekuthuthuke ngokushesha eminyakeni yamuva futhi sekuqalile ukumila. Njengamanje, ama-electrode e-graphite electrode ezwe lakithi anamandla amakhulu ikakhulukazi ayi-coke yenaliti eyenziwe ngamalahle. Mayelana nokukhiqizwa okuphelele, amayunithi okukhiqiza izinaliti zasekhaya angakwazi ukuhlangabezana nezidingo zamabhizinisi ekhabhoni ukuze akhiqize ama-electrode e-graphite aphezulu/amandla e-coke yenaliti. Kodwa-ke, lisekhona igebe elithile uma liqhathaniswa nezinkampani zakwamanye amazwe ngekhwalithi yenaliti coke. Izinto zokusetshenziswa ze-ultra-high-power graphite electrode zisathembele ku-coke yenaliti engenisiwe, ikakhulukazi amajoyinti ama-electrode e-graphite aphezulu/amandla amakhulu angeniswa kwamanye amazwe. Inaliti coke njengoba impahla eluhlaza.
Ngo-2021, ukukhiqizwa kwensimbi yasekhaya kuzoba amathani ayizigidi eziyizinkulungwane eziyi-1.037, lapho ukwenziwa kwensimbi yesithando somlilo kagesi kubalwa ngaphansi kuka-10%. UMnyango Wezimboni Nobuchwepheshe Bolwazi ngokuhlanganyela uhlela ukwandisa ingxenye yokwenziwa kwensimbi yesithando sikagesi ibe ngaphezu kuka-15% ngo-2025. I-National Iron and Steel Association ibikezela ukuthi izofinyelela ku-30% ngo-2050.Izofinyelela ku-60% ngo-2060. isilinganiso se-steelmaking sezithando zikagesi sizoqhuba ngokuqondile isidingo sama-graphite electrode, futhi-ke, isidingo se-coke yenaliti.
