1. Iindawo zesicelo se-anode yebhetri yeLithium:
Okwangoku, izinto ezithengiswayo ze-anode ziyi-graphite yendalo kunye negraphite yokwenziwa. Inaliti yecoke kulula ukuba yenziwe igraphiti kwaye luhlobo lwemathiriyeli ekrwada eyenziweyo ekumgangatho ophezulu. Emva kwe-graphitization, inesakhiwo esicacileyo se-fibrous kunye nesakhiwo esihle se-graphite microcrystalline. Kwisalathiso se-axis ende yeengqungquthela, ineenzuzo zombane kunye ne-thermal conductivity kunye ne-coefficient encinci yokwandisa i-thermal. Inaliti ye-coke ityunyuziwe, ihlelwe, ibunjwe, igranulated, kunye ne-graphitized ukufumana izinto eziphathekayo zegraphite, ezinomgangatho ophezulu we-crystallinity kunye ne-graphitization, kwaye isondele kwisakhiwo esifanelekileyo se-graphite.
Ishishini elitsha lezithuthi zamandla liphuhliswe ngokukhawuleza kwiminyaka yakutshanje. Ukusukela ngoJanuwari ukuya kuSeptemba ka-2022, imveliso eyongezelekayo yeebhetri zamandla kwilizwe lam yi-372GWh, ukonyuka konyaka ngonyaka nge-176%. I-China Automobile Association iqikelela ukuba ukuthengiswa okupheleleyo kwezithuthi zombane kuya kufikelela kwi-5.5 yezigidi kwi-2022, kwaye izinga lokungena kwezithuthi zombane kulo nyaka liya kudlula i-5.5 yezigidi. 20%. Ukuthotyelwa ngamazwe ngamazwe "umgca obomvu wokuvalwa kokutsha" kunye nomgaqo-nkqubo wasekhaya "weenjongo zekhabhoni ezimbini", imfuno yehlabathi jikelele yeebhetri ze-lithium kulindeleke ukuba ifike kwi-3,008GWh ngo-2025, kwaye imfuno ye-needle coke iya kufikelela kwi-4.04 yezigidi zeetoni.
2. Iindawo zokusetyenziswa kwe-electrode yegraphite:
Inaliti coke yimathiriyeli ekumgangatho ophezulu wokuvelisa i-electrode yegraphite yamandla aphezulu/aphezulu. Ukubonakala kwayo kunokwakheka kwe-fibrous texture ephuhliswe kakuhle kunye ne-particle enkulu ubude-width ratio. Ngethuba lokubunjwa kwe-extrusion, i-axis ende yeengqungquthela ezininzi zicwangciswe kunye nolwalathiso lwe-extrusion. . Ukusetyenziswa kwe-coke yenaliti ukuvelisa i-electrode ye-graphite ephezulu / ephezulu ineenzuzo zokuxhathisa okuphantsi, i-coefficient ephantsi yokwandiswa kwe-thermal, ukuxhathisa ukutshatyalaliswa kwe-thermal, ukusetyenziswa kwe-electrode ephantsi kunye nobuninzi obuvumelekileyo obukhoyo. Iicoke zeenaliti ezisekelwe ngamalahle kunye neoli zineempawu zazo ekusebenzeni. Xa kuthelekiswa nokusebenza kwenaliti ye-coke, ukongeza kubuninzi bokwenene, ubuninzi bempompo, ukumelana nomgubo, umxholo womlotha, umxholo wesulfure, umxholo we-nitrogen, Ukongeza kuthelekiso lwezalathisi zokusebenza eziqhelekileyo ezifana nomlinganiselo we-aspect ratio kunye nokusabalalisa ubungakanani besuntswana, ingqalelo kufuneka iqwalaselwe. Kwakhona kuhlawulwe kwi-coefficient yokwandiswa kwe-thermal, ukuxhathisa, amandla oxinzelelo, ubuninzi bobuninzi, ubuninzi bokwenyani, ukwanda kobuninzi, i-anisotropy, imeko engathintekiyo kunye nohlalutyo kunye novavanyo lwezibonakaliso zeempawu ezifana nokwandiswa kwedatha kwimeko ethintelweyo, uluhlu lobushushu ngexesha lokwandiswa kunye nokunciphisa, njl. Ezi zalathi zeempawu zibaluleke kakhulu ukulungelelanisa iiparamitha zenkqubo kwinkqubo yokuvelisa i-electrode yegraphite kunye nokulawula ukusebenza kwee-electrode zegraphite. Lilonke, ukusebenza kwe-oyile yenaliti ye-oyile kuphezulu kancinane kune-coke yenaliti esekwe ngamalahle.
Amashishini ekhabhoni angaphandle ahlala ekhetha i-oyile yenaliti ekumgangatho ophezulu njengeyona nto iphambili ekuveliseni i-UHP enkulu kunye ne-HP graphite electrode. Amashishini ekhabhoni yaseJapan nawo asebenzisa icoke enaliti esekwe emalahleni njengemathiriyeli ekrwada, kodwa kuphela ukuvelisa i-electrode yegraphite eneenkcukacha ezingaphantsi kwe-Φ600mm. Nangona ukuveliswa kwemveliso yenaliti ye-coke kwilizwe lam emva kwexesha leenkampani zangaphandle, sele iphuhliswe ngokukhawuleza kwiminyaka yamuva kwaye iqalile ukumila. Okwangoku, i-aggregates ye-electrode ye-graphite yelizwe lam yamandla aphezulu ikakhulu isekwe ngamalahle inaliti. Ngokubhekiselele kwimveliso epheleleyo, iiyunithi zemveliso zenaliti yasekhaya zinokuhlangabezana neemfuno zamashishini ekhabhoni ukuvelisa i-electrode yegraphite ephezulu/ye-ultra-power ye-coke yenaliti. Nangona kunjalo, kusekho i-gap ethile xa kuthelekiswa neenkampani zangaphandle kumgangatho wenaliti ye-coke. Izixhobo ekrwada yegraphite electrode yomgangatho omkhulu we-ultra-high-power isaxhomekeke kwi-coke yenaliti ephuma kumazwe angaphandle, ingakumbi i-high/ultra-power graphite electrode joints are imported. Inaliti ye-coke njengento ekrwada.
Ngo-2021, imveliso yensimbi yasekhaya iya kuba yi-1.037 yeetoni zeebhiliyoni, apho i-steelmaking yesithando sombane isenza i-akhawunti engaphantsi kwe-10%. UMphathiswa wezoShishino kunye neTeknoloji yoLwazi ngokudibeneyo uceba ukunyusa umlinganiselo we-steelmaking yentsimbi yombane ukuya ngaphezu kwe-15% ngo-2025. I-National Iron and Steel Association iqikelela ukuba iya kufikelela kwi-30% ngo-2050.Iya kufikelela kwi-60% ngo-2060. i-steelmaking ratio ye-furnaces yombane iya kuqhuba ngokuthe ngqo imfuno ye-graphite electrode, kwaye ngokuqinisekileyo, imfuno ye-coke yenaliti.
