1. Oghere ngwa batrị anode lithium:
Ka ọ dị ugbu a, ihe anode a na-ere ahịa bụ nke kacha graphite eke na graphite artificial. Coke agịga dị mfe ka a na-esepụta ya na ọ bụ ụdị akụrụngwa graphite arụrụ arụ dị elu. Mgbe graphitization gasịrị, ọ nwere usoro fibrous doro anya yana ezigbo microcrystalline graphite. Na ntụziaka nke ogologo axis nke irighiri ihe, ọ nwere uru nke ezigbo ọkụ eletrik na thermal conductivity na obere ọnụọgụ mgbasawanye ọkụ. A na-egwepịa coke agịga, nkewa, kpụrụ ya, granulated, na eserese iji nweta ihe osise graphite wuru, nke nwere ogo kristal na eserese dị elu, ma dịkwa nso n'ụdị nwere akwa graphite zuru oke.
Ụlọ ọrụ ụgbọ ala ume ọhụrụ amalitela ngwa ngwa n'afọ ndị na-adịbeghị anya. Site na Jenụwarị ruo Septemba 2022, mkpokọta batrị ike na mba m bụ 372GWh, mmụba kwa afọ nke 176%.

2. graphite electrode ubi ngwa:
agịga coke bụ ihe dị elu maka imepụta electrodes graphite dị elu / ultra-high ike. Ọdịdị ya nwere usoro udidi fibrous emepụtara nke ọma na nnukwu akụkụ ogologo-obosara. N'oge extrusion ịkpụzi, ogologo axis nke ọtụtụ ahụ na-ahaziri tinyere extrusion direction. . Ojiji nke coke agịga na-emepụta electrodes graphite dị elu / ultra-high nwere uru nke obere resistivity, obere mgbasawanye ọkụ ọkụ, nkwụsị ọkụ ọkụ siri ike, obere electrode oriri na nnukwu ohere ugbu a njupụta. Coal nke dabeere na coal na mmanụ mmanụ nwere àgwà nke ha na arụmọrụ. Na ntụnyere nke agịga coke arụmọrụ, na mgbakwunye na ezi njupụta, mgbata njupụta, powder resistivity, ash ọdịnaya, sọlfọ ọdịnaya, nitrogen ọdịnaya, Na mgbakwunye na ntụnyere ot arụmọrụ egosi dị ka akụkụ ruru na urughuru size nkesa, nlebara anya kwesịrị. a ga-akwụkwa ya na ọnụọgụ mgbasawanye thermal, resistivity, compressive ike, nnukwu njupụta, ezi njupụta, nnukwu mgbasawanye, anisotropy, steeti na-egbochighị ya na nyocha na nyocha nke njirimara njirimara dị ka data mgbasawanye na steeti a na-egbochi, ọnọdụ okpomọkụ n'oge mgbasawanye na nkwekọrịta, wdg Ihe ngosi njirimara ndị a dị ezigbo mkpa iji dozie usoro usoro na mmepụta nke electrodes graphite na ijikwa ọrụ nke electrodes graphite. N'ozuzu ya, arụmọrụ nke coke agịga na-adabere na mmanụ dị ntakịrị elu karịa nke coke coke dabeere na coal.
Ụlọ ọrụ carbon nke mba ọzọ na-ahọrọkarị coke agịga mmanụ dị elu dị ka isi akụrụngwa maka imepụta nnukwu UHP na HP graphite electrodes. Ụlọ ọrụ ndị Japan na-arụ ọrụ carbon na-ejikwa ụfọdụ coke agịga coal dị ka akụrụngwa, mana ọ bụ naanị maka mmepụta nke electrodes graphite nwere nkọwa n'okpuru Φ600mm. Ọ bụ ezie na mmepụta mmepụta nke coke coke na mba m na-emecha karịa nke ụlọ ọrụ mba ọzọ, ọ na-etolite ngwa ngwa n'afọ ndị na-adịbeghị anya ma malite ịmalite. Ka ọ dị ugbu a, mkpokọta elektrọd graphite nwere ike dị elu nke obodo m bụ coke nke agịga sitere na coal. N'ihe gbasara mkpokọta mmepụta, ngalaba mmepụta coke agịga nwere ike na-egbo mkpa nke ụlọ ọrụ carbon iji mepụta electrodes graphite dị elu / ultra-power maka agịga coke. Otú ọ dị, a ka nwere ụfọdụ ọdịiche ma e jiri ya tụnyere ụlọ ọrụ mba ọzọ na àgwà coke agịga. Ngwa ngwa graphite nke nwere nnukwu oke ọkụ ka na-adabere na coke agịga ebubata, ọkachasị akwa / ultra-power graphite electrode nkwonkwo na-ebubata. Agụba coke dị ka akụrụngwa.
Na 2021, mmepụta ígwè ụlọ ga-abụ ijeri tọn 1.037, nke ọkụ ọkụ eletrik na-akpata ihe na-erughị 10%. Ministri nke ụlọ ọrụ na teknụzụ ozi jikọtara ọnụ na-ezube ịbawanye nha nke igwe ọkụ eletrik karịa 15% na 2025. National Iron and Steel Association na-ebu amụma na ọ ga-eru 30% na 2050. Ọ ga-eru 60% na 2060. Ogo nchara nke ọkụ eletrik ga-eme ka ọchịchọ nke electrodes graphite ozugbo, na n'ezie, ọchịchọ coke agịga.
