1. Izinkambu zohlelo lokusebenza lwe-anode yebhethri le-lithium:
Njengamanje, izinto ze-anode ezithengiswayo ziyi-graphite yemvelo kanye ne-graphite yokwenziwa. I-Needle coke kulula ukuyi-graphit futhi iwuhlobo lwezinto zokusetshenziswa ze-graphite zokwenziwa ezisezingeni eliphezulu. Ngemva kokuyi-graphit, inesakhiwo esicacile se-fibrous kanye nesakhiwo esihle se-graphite microcrystalline. Ngasohlangothini lwe-axis ende yezinhlayiya, inezinzuzo zokuqhuba kahle kukagesi nokushisa kanye ne-coefficient encane yokwandisa ukushisa. I-Needle coke iyachotshozwa, ihlukaniswe, ibunjwe, igoqwe, futhi i-graphitized ukuze kutholakale izinto ze-graphite zokwenziwa, ezinezinga eliphezulu le-crystallinity kanye ne-graphitization, futhi iseduze nesakhiwo esiphelele se-graphite layered.
Imboni yezimoto ezintsha zamandla ithuthuke ngokushesha eminyakeni yamuva nje. Kusukela ngoJanuwari kuya kuSepthemba 2022, umkhiqizo ohlanganisiwe wamabhethri kagesi ezweni lami ungu-372GWh, ukwanda konyaka nonyaka okungu-176%. I-China Automobile Association ibikezela ukuthi inani lokuthengiswa kwezimoto zikagesi lizofinyelela ku-5.5 million ngo-2022, kanti izinga lokungena kwezimoto zikagesi unyaka wonke lizodlula ku-5.5 million. 20%. Ithonywe "umugqa obomvu wokuvimbela ukushisa" wamazwe ngamazwe kanye nenqubomgomo yasekhaya "yemigomo ye-carbon ephindwe kabili", isidingo somhlaba wonke samabhethri e-lithium kulindeleke ukuthi sifinyelele ku-3,008GWh ngo-2025, kanti isidingo se-needle coke sizofinyelela ku-4.04 million tons.
2. Amasimu okusetshenziswa kwe-graphite electrode:
I-Needle coke iyinto esezingeni eliphezulu yokukhiqiza ama-electrode e-graphite anamandla aphezulu/aphezulu. Ukubukeka kwayo kunesakhiwo sokuthungwa kwe-fibrous esithuthukisiwe kahle kanye nesilinganiso esikhulu sobude nobubanzi bezinhlayiya. Ngesikhathi sokubumba i-extrusion, i-axis ende yezinhlayiya eziningi ihlelwe ngendlela ye-extrusion. . Ukusetshenziswa kwe-needle coke ukukhiqiza ama-electrode e-graphite anamandla aphezulu/aphezulu kunezinzuzo zokumelana okuphansi, i-coefficient yokwanda kokushisa okuphansi, ukumelana okunamandla kokushaqeka kokushisa, ukusetshenziswa kwe-electrode okuphansi kanye nobuningi bamanje obuvumelekile. Ama-needle coke asekelwe emalahleni nasekelwe ku-oyela anezici zawo ekusebenzeni. Ekuqhathanisweni kokusebenza kwe-needle coke, ngaphezu kobuningi beqiniso, ubuningi be-tap, ukumelana ne-powder, okuqukethwe komlotha, okuqukethwe kwe-sulfur, okuqukethwe kwe-nitrogen, Ngaphezu kokuqhathaniswa kwezinkomba zokusebenza ezivamile ezifana ne-aspect ratio kanye nokusatshalaliswa kosayizi wezinhlayiyana, kufanele futhi kuqashelwe i-thermal expansion coefficient, resistivity, compressive strength, bulk density, true density, bulk expansion, anisotropy, uninhibited state kanye nokuhlaziywa kanye nokuhlolwa kwezinkomba zezimpawu ezifana nedatha yokwanda esimweni esivinjelwe, izinga lokushisa ngesikhathi sokwanda kanye nokuncipha, njll. Lezi zinkomba zezimpawu zibaluleke kakhulu ukulungisa amapharamitha enqubo enqubweni yokukhiqiza ama-graphite electrodes nokulawula ukusebenza kwama-graphite electrodes. Sekukonke, ukusebenza kwe-needle coke esekelwe ku-oyela kuphakeme kancane kunokwe-needle coke esekelwe kumalahle.
Amabhizinisi ekhabhoni angaphandle avame ukukhetha i-coke yamafutha ekhwalithi ephezulu njengezinto zokusetshenziswa eziyinhloko zokukhiqiza ama-electrode amakhulu e-UHP kanye ne-HP graphite. Amabhizinisi ekhabhoni aseJapan asebenzisa ne-coke yamalitha esuselwe kumalahle njengezinto zokusetshenziswa, kodwa kuphela ekukhiqizweni kwama-electrode e-graphite anezincazelo ezingaphansi kwe-Φ600mm. Nakuba ukukhiqizwa kwezimboni kwe-coke yamalitha ezweni lakithi sekudlule isikhathi kunokwezinkampani zakwamanye amazwe, kuthuthuke ngokushesha eminyakeni yamuva nje futhi sekuqalile ukubonakala. Njengamanje, ama-electrode e-graphite anamandla aphezulu ezweni lami ikakhulukazi ama-coke asekelwe kumalahle. Ngokuphathelene nokukhiqizwa okuphelele, amayunithi okukhiqiza i-coke yasekhaya angahlangabezana nezidingo zamabhizinisi ekhabhoni ukukhiqiza ama-electrode e-graphite aphezulu/amandla aphezulu e-coke yamalitha. Kodwa-ke, kusenesikhala esithile uma kuqhathaniswa nezinkampani zakwamanye amazwe ngekhwalithi ye-coke yamalitha. Izinto zokusetshenziswa ze-graphite electrode yamandla aphezulu kakhulu zisathembele ku-coke yamalitha engenisiwe, ikakhulukazi amajoyinti e-electrode e-graphite aphezulu/amandla aphezulu angeniswa. I-coke yamalitha njengezinto zokusetshenziswa.
Ngo-2021, ukukhiqizwa kwensimbi yasekhaya kuzoba ngamathani ayizigidigidi eziyi-1.037, lapho ukwenziwa kwensimbi yesithando sikagesi kubalwa ngaphansi kuka-10%. UMnyango Wezimboni Nobuchwepheshe Bolwazi uhlela ngokuhlanganyela ukwandisa inani lokwenziwa kwensimbi yesithando sikagesi libe ngaphezu kuka-15% ngo-2025. I-National Iron and Steel Association ibikezela ukuthi izofinyelela ku-30% ngo-2050. Izofinyelela ku-60% ngo-2060. Ukwandisa isilinganiso sokwenza insimbi yezithando zikagesi kuzothuthukisa ngqo isidingo sama-electrode e-graphite, futhi-ke, isidingo se-needle coke.
