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 kwempuphu, okuqukethwe komlotha, okuqukethwe kwesibabule, okuqukethwe kwe-nitrogen, Ngaphezu kokuqhathanisa izinkomba zokusebenza ezijwayelekile ezifana ne-aspect ratio kanye nokusabalalisa usayizi wezinhlayiyana, ukunakwa kufanele kukhokhwe ku-coefficient yokwanda okushisayo, ukumelana, amandla okucindezela, ukuminyana kweqiniso, ukuminyana kwenqwaba, ukuminyana kwenqwaba isimo esingavinjiwe kanye Ukuhlaziywa nokuhlolwa kwezinkomba zesici ezifana nedatha yokwandisa esimweni esivinjelwe, izinga lokushisa ngesikhathi sokunwetshwa nokufinyela, njll. Lezi zinkomba zesici zibaluleke kakhulu ukulungisa imingcele yenqubo ekukhiqizeni ama-electrode e-graphite nokulawula ukusebenza kwama-electrode e-graphite. 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 ukukhulisa 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. ukhokho.
