1. Amasimi okusetyenziswa kwe-anode yebhetri yeLithium:
Okwangoku, izinto ze-anode ezithengiswayo ikakhulu ziigrafiti yendalo kunye negrafiti yokwenziwa. I-Needle coke kulula ukuyigrafiti kwaye luhlobo lwezinto ezisemgangathweni ophezulu zegrafiti yokwenziwa. Emva kokugrafiti, inesakhiwo esicacileyo se-fibrous kunye nesakhiwo esihle se-graphite microcrystalline. Ngakwicala le-axis ende yamasuntswana, ineengenelo zokuqhuba umbane kunye nobushushu obuhle kunye ne-coefficient encinci yokwandisa ubushushu. I-Needle coke iyatyunyuzwa, ihlulwe, imile, igobile, kwaye yenziwe igrafiti ukuze kufunyanwe izinto zegrafiti yokwenziwa, enezinga eliphezulu lekristali kunye negrafiti, kwaye ikufutshane nesakhiwo esigqibeleleyo segrafiti.
Ishishini lezithuthi zamandla elitsha liphuhlile ngokukhawuleza kwiminyaka yakutshanje. Ukususela ngoJanuwari ukuya kuSeptemba 2022, imveliso eqokelelweyo yeebhetri zamandla kwilizwe lam yi-372GWh, ukwanda konyaka nonyaka kwe-176%. I-China Automobile Association iqikelela ukuba intengiso iyonke yezithuthi zombane iya kufikelela kwi-5.5 yezigidi ngo-2022, kwaye izinga lokungena kwezithuthi zombane kulo lonke unyaka liya kudlula kwi-5.5 yezigidi. 20%. Iphenjelelwa "ngumgca obomvu wokuthintelwa kokutshisa" wamazwe ngamazwe kunye nomgaqo-nkqubo wasekhaya we "dual carbon goals", imfuno yehlabathi yeebhetri ze-lithium kulindeleke ukuba ifikelele kwi-3,008GWh ngo-2025, kwaye imfuno ye-needle coke iya kufikelela kwi-4.04 yezigidi zeetoni.
2. Amasimi okusetyenziswa kwe-graphite electrode:
I-Needle coke sisixhobo esisemgangathweni ophezulu sokwenza ii-electrode ze-graphite ezinamandla aphezulu/aphezulu. Inkangeleko yayo inesakhiwo esiphuhlileyo se-fibrous texture kunye nomlinganiselo omkhulu wobude nobubanzi be-particle. Ngexesha lokubumba i-extrusion, i-axis ende yee-particles ezininzi icwangciswa kwicala le-extrusion. . Ukusetyenziswa kwe-needle coke ukuvelisa ii-electrode ze-graphite ezinamandla aphezulu/aphezulu kuneenzuzo zokumelana okuphantsi, i-coefficient yokwandiswa kobushushu obuphantsi, ukumelana okunamandla kobushushu, ukusetyenziswa kwe-electrode ephantsi kunye noxinano oluphezulu oluvumelekileyo lwamandla. Ii-needle coke ezisekelwe kumalahle kunye ne-oyile zineempawu zazo ekusebenzeni. Xa kuthelekiswa ukusebenza kwe-needle coke, ukongeza kwi-true density, i-tap density, i-powder resistivity, i-ash content, i-sulfur content, i-nitrogen content. Ukongeza ekuthelekisweni kwezalathisi zokusebenza eziqhelekileyo ezifana nomlinganiselo we-aspect kunye nokusasazwa kobungakanani be-particle, kufuneka kuqwalaselwe i-thermal expansion coefficient, i-resistivity, amandla okucinezela, i-bulk density, i-true density, i-bulk expansion, i-anisotropy, i-uninhibited state kunye noHlahlelo kunye novavanyo lwezalathisi zeempawu ezifana nedatha yokwandiswa kwimeko ethintelweyo, uluhlu lobushushu ngexesha lokwandiswa kunye nokucutheka, njl. Ezi zalathisi zeempawu zibaluleke kakhulu ukulungisa iiparameter zenkqubo kwinkqubo yokuvelisa ii-graphite electrodes kunye nokulawula ukusebenza kwee-graphite electrodes. Lilonke, ukusebenza kwe-needle coke esekwe kwioyile kuphezulu kancinci kunokwe-needle coke esekwe kumalahle.
Amashishini ekhabhoni angaphandle adla ngokukhetha i-oyile ye-needle coke esemgangathweni ophezulu njengezinto eziphambili zokwenza i-electrodes ezinkulu ze-UHP kunye ne-HP graphite. Amashishini ekhabhoni aseJapan asebenzisa i-needle coke esekwe kumalahle njengezinto zokwenza i-ayikhri, kodwa kuphela ekuveliseni i-electrodes ze-graphite ezineenkcazo ezingaphantsi kwe-Φ600mm. Nangona imveliso ye-needle coke yemizi-mveliso kwilizwe lam idlulele kuneyeenkampani zangaphandle, ikhule ngokukhawuleza kwiminyaka yakutshanje kwaye iqalile ukuthatha imo. Okwangoku, ii-electrode ze-graphite ezinamandla aphezulu zelizwe lam ikakhulu zi-needle coke esekwe kumalahle. Ngokuphathelele imveliso iyonke, iiyunithi zemveliso ye-needle coke zasekhaya zinokuhlangabezana neemfuno zamashishini ekhabhoni ukuvelisa i-electrodes ze-graphite ezinamandla aphezulu/aphezulu ze-needle coke. Nangona kunjalo, kusekho umsantsa othile xa kuthelekiswa neenkampani zangaphandle kumgangatho we-needle coke. Izinto zokwenza i-graphite electrode enamandla aphezulu kakhulu zisaxhomekeke kwi-needle coke engeniswe kwamanye amazwe, ngakumbi ii-electrode ze-graphite electrode ezinamandla aphezulu/aphezulu ezingeniswa kwamanye amazwe. I-Needle coke njengezinto zokwenza i-ayikhri.
Ngowama-2021, imveliso yentsimbi yasekhaya iya kuba yi-1.037 yeebhiliyoni zeetoni, apho ukwenza intsimbi yesithando sombane kubiza ngaphantsi kwe-10%. UMphathiswa wezeShishini kunye neTekhnoloji yoLwazi uceba ngokudibeneyo ukwandisa inani lokwenza intsimbi yesithando sombane ukuya ngaphezulu kwe-15% ngo-2025. I-National Iron and Steel Association iqikelela ukuba iya kufikelela kwi-30% ngo-2050. Iya kufikelela kwi-60% ngo-2060. Ukunyusa umlinganiselo wokwenza intsimbi yezithando zombane kuya kuqhuba ngqo imfuno yee-electrode ze-graphite, kwaye ewe, imfuno ye-needle coke.
