Mai ka makahiki 2018, ua piʻi nui ka mana hana o nā electrode graphite ma Kina. Wahi a ka ʻikepili a Baichuan Yingfu, ʻo ka mana hana aupuni he 1.167 miliona tons i ka makahiki 2016, me ka haʻahaʻa o ka hoʻohana ʻana i ka mana e like me 43.63%. I ka makahiki 2017, ua hōʻea ka mana hana o nā electrode graphite o Kina i ka liʻiliʻi loa o 1.095 miliona tons, a laila me ka hoʻomaikaʻi ʻana o ka pōmaikaʻi o ka ʻoihana, e hoʻomau ʻia ka hoʻokomo ʻana i ka mana hana i ka makahiki 2021. ʻO ka mana hana o nā electrode graphite o Kina he 1.759 miliona tons, he 61% i piʻi aʻe mai ka makahiki 2017. I ka makahiki 2021, ʻo ka hoʻohana ʻana i ka mana o ka ʻoihana he 53%. I ka makahiki 2018, ʻo ka nui o ka hoʻohana ʻana i ka mana o ka ʻoihana electrode graphite i hōʻea i ka 61.68%, a laila hoʻomau i ka emi ʻana. Manaʻo ʻia ka hoʻohana ʻana i ka mana i ka makahiki 2021 he 53%. Hoʻolaha nui ʻia ka mana o ka ʻoihana electrode graphite ma ka ʻākau o Kina a me ka hikina ʻākau o Kina. I ka makahiki 2021, ʻoi aku ka nui o ka hana ʻana o ka electrode graphite ma ka ʻĀkau a me ka ʻākau hikina o Kina ma mua o 60%. Mai ka makahiki 2017 a i ka makahiki 2021, e paʻa ana ka mana hana o ka electrode graphite kūlanakauhale "2+26" ma 400,000 a 460,000 tons.
Mai ka makahiki 2022 a i ka makahiki 2023, e emi ana ka nui o ka electrode graphite hou. I ka makahiki 2022, ua manaʻo ʻia he 120,000 tons ka nui o ka electrode graphite hou, a i ka makahiki 2023, ua manaʻo ʻia he 270,000 tons ka nui o ka electrode graphite hou. Inā paha e hiki ke hoʻokomo ʻia kēia ʻāpana o ka mana hana i ka wā e hiki mai ana, e hilinaʻi mau ana ia i ka loaʻa kālā o ka mākeke electrode graphite a me ka nānā ʻana o ke aupuni i ka ʻoihana hoʻohana ikehu kiʻekiʻe, aia kekahi mau mea kānalua.
No ka ʻoihana hoʻohana ikehu kiʻekiʻe ka electrode graphite a me ka hoʻokuʻu kalapona kiʻekiʻe. ʻO ka hoʻokuʻu kalapona no kēlā me kēia tona o ka electrode graphite he 4.48 tons, ʻoi aku ka haʻahaʻa ma mua o ka metala silicon a me ka alumini electrolytic. Ma muli o ke kumukūʻai kalapona o 58 yuan/ton ma Ianuali 10, 2022, ʻo ke kumukūʻai hoʻokuʻu kalapona he 1.4% o ke kumukūʻai o ka electrode graphite mana kiʻekiʻe. ʻO ka hoʻohana mana no kēlā me kēia tona o ka electrode graphite he 6000 KWH. Inā helu ʻia ke kumukūʻai uila ma 0.5 yuan/KWH, ʻo ke kumukūʻai uila he 16% o ke kumukūʻai o ka electrode graphite.
Ma lalo o ke kua o ka "mana pālua" o ka hoʻohana ʻana i ka ikehu, ua kāohi nui ʻia ka wikiwiki o ka hana o ke kila eAF ma lalo me ka electrode graphite. Mai Iune 2021, ua emi loa ka wikiwiki o ka hana o 71 mau ʻoihana kila eAF ma kahi o ʻekolu mau makahiki, a ua kāohi nui ʻia ke koi no ka electrode graphite.
ʻO ka hoʻonui ʻia ʻana o ka puka ʻana o nā electrode graphite ma waho a me ka hakahaka o ka lako a me ke koi no ka electrode graphite mana ultra-kiʻekiʻe. Wahi a ka ʻikepili Frost & Sullivan, ua emi ka puka ʻana o ka electrode graphite ma nā ʻāina ʻē aʻe o ka honua mai 804,900 tons i ka makahiki 2014 a i 713,100 tons i ka makahiki 2019, nona ka puka ʻana o ka electrode graphite mana ultra-kiʻekiʻe ma kahi o 90%. Mai ka makahiki 2017, ʻo ka hoʻonui ʻia ʻana o ka hakahaka o ka lako a me ke koi o ka electrode graphite ma nā ʻāina ʻē e hele mai ana mai ka electrode graphite mana ultra-kiʻekiʻe, i hoʻokumu ʻia e ka ulu nui ʻana o ka puka kila maka o ka umu uila ma waho mai 2017 a i 2018. I ka makahiki 2020, ua emi ka hana ʻana o ke kila umu uila ma waho ma muli o nā kumu maʻi ahulau. I ka makahiki 2019, ua hōʻea ka hoʻokuʻu aku ʻana o Kina i ka electrode graphite i 396,300 tons. I ka makahiki 2020, i hoʻopilikia ʻia e ka maʻi ahulau, ua hāʻule nui ka hana kila umu uila ma waho i 396 miliona tons, i lalo o 4.39% makahiki ma ka makahiki, a ua hāʻule ka hoʻokuʻu aku ʻana o Kina i ka electrode graphite i 333,900 tons, i lalo o 15.76% makahiki ma ka makahiki.
