1. Nā kahua noi anode pākahiko Lithium:
I kēia manawa, ʻo nā mea anode i kālepa ʻia he graphite maoli a me ka graphite artificial. He maʻalahi ke graphitized i ka Needle Coke a he ʻano mea maka graphite artificial kiʻekiʻe. Ma hope o ka graphitization, he ʻano fibrous maopopo a me ke ʻano microcrystalline graphite maikaʻi. Ma ke kuhikuhi o ke axis lōʻihi o nā ʻāpana, loaʻa iā ia nā pono o ka conductivity uila a me ka thermal maikaʻi a me ka coefficient hoʻonui thermal liʻiliʻi. Kuʻi ʻia ka Needle Coke, hoʻokaʻawale ʻia, hoʻohālike ʻia, granulated, a graphitized e loaʻa ai ka mea graphite artificial, nona ke kiʻekiʻe o ka crystallinity a me ka graphitization, a kokoke i kahi ʻano papa graphite kūpono.
Ua ulu wikiwiki ka ʻoihana kaʻa ikehu hou i nā makahiki i hala iho nei. Mai Ianuali a Kepakemapa 2022, ʻo ka huina o nā pila mana ma koʻu ʻāina he 372GWh, he piʻi makahiki-ma-makahiki o 176%. Ua wānana ka China Automobile Association e hiki aku ka huina o nā kūʻai aku o nā kaʻa uila i 5.5 miliona i ka makahiki 2022, a ʻo ka nui o ke komo ʻana o nā kaʻa uila i loko o ka makahiki e ʻoi aku ma mua o 5.5 miliona. 20%. Ma muli o ka "laina ʻulaʻula o ka pāpā ʻana i ka puhi ʻana" o ka honua a me ke kulekele kūloko o "nā pahuhopu kalapona pālua", manaʻo ʻia e hiki aku ka noi honua no nā pila lithium i 3,008GWh i ka makahiki 2025, a e hiki aku ka noi no ka nila coke i 4.04 miliona tons.
2. Nā kahua noi electrode graphite:
He mea kiʻekiʻe ke ʻano o ka nila coke no ka hana ʻana i nā electrodes graphite mana kiʻekiʻe/ultra-kiʻekiʻe. Loaʻa i kona helehelena kahi ʻano fibrous i hoʻomohala maikaʻi ʻia a me kahi ratio lōʻihi-ākea o nā ʻāpana nui. I ka wā o ka hoʻoheheʻe ʻana o ka extrusion, ua hoʻonohonoho ʻia ke axis lōʻihi o ka hapa nui o nā ʻāpana ma ke kuhikuhi extrusion. . ʻO ka hoʻohana ʻana i ka nila coke e hana i nā electrodes graphite mana kiʻekiʻe/ultra-kiʻekiʻe he mau pono o ka resistivity haʻahaʻa, ka coefficient hoʻonui wela haʻahaʻa, ke kūpaʻa haʻalulu wela ikaika, ka hoʻohana ʻana i ka electrode haʻahaʻa a me ke kiʻekiʻe o ke au i ʻae ʻia. Loaʻa i nā nila cokes i hoʻokumu ʻia i ka lanahu a me ka ʻaila ko lākou mau ʻano ponoʻī i ka hana. I ka hoʻohālikelike ʻana i ka hana o ka nila coke, me ka hoʻohui ʻana i ka ʻoiaʻiʻo maoli, ka nui o ka piula wai, ke kūʻē ʻana o ka pauka, ka ʻike lehu, ka ʻike sulfur, a me ka ʻike naikokene. Ma waho aʻe o ka hoʻohālikelike ʻana i nā ʻōkuhi hana maʻamau e like me ka lakio hiʻohiʻona a me ka hoʻolaha ʻana o ka nui o ka ʻāpana, pono e uku ʻia ka nānā ʻana i ke koina hoʻonui wela, ke kūʻē ʻana, ka ikaika compressive, ka nui o ka nui, ka nui o ka nui, ka hoʻonui ʻana o ka nui, ka anisotropy, ke kūlana i kāohi ʻole ʻia a me ka loiloi ʻana i nā ʻōkuhi hiʻohiʻona e like me ka ʻikepili hoʻonui i ke kūlana i kāohi ʻia, ka pae mahana i ka wā o ka hoʻonui ʻana a me ka ʻaelike ʻana, a pēlā aku. He mea nui loa kēia mau ʻōkuhi hiʻohiʻona e hoʻoponopono i nā palena hana i ke kaʻina hana o nā electrodes graphite a e kāohi i ka hana o nā electrodes graphite. Ma ke ʻano holoʻokoʻa, ʻoi aku ka kiʻekiʻe o ka hana o ka nila coke aila ma mua o ka nila coke lanahu.
Hoʻohana pinepine nā ʻoihana kalapona haole i ka coke nila aila kiʻekiʻe ma ke ʻano he mea maka nui no ka hana ʻana i nā electrodes graphite UHP a me HP nui. Hoʻohana pū nā ʻoihana kalapona Kepani i kekahi coke nila lanahu ma ke ʻano he mea maka, akā no ka hana ʻana i nā electrodes graphite me nā kikoʻī ma lalo o Φ600mm. ʻOiai ʻoi aku ka lōʻihi o ka hana ʻana o ka coke nila ma koʻu ʻāina ma mua o nā ʻoihana haole, ua ulu wikiwiki ia i nā makahiki i hala iho nei a ua hoʻomaka e lawe i ke ʻano. I kēia manawa, ʻo nā hui electrode graphite mana kiʻekiʻe o koʻu ʻāina he coke nila lanahu nui. Ma ke ʻano o ka hana holoʻokoʻa, hiki i nā ʻāpana hana coke nila kūloko ke hoʻokō i nā pono o nā ʻoihana kalapona e hana i nā electrodes graphite kiʻekiʻe/ultra-mana no ka coke nila. Eia nō naʻe, aia nō kekahi ʻokoʻa i hoʻohālikelike ʻia me nā ʻoihana haole i ke ʻano o ka coke nila. Hilinaʻi mau nā mea maka electrode graphite ultra-kiʻekiʻe nui i ka coke nila i lawe ʻia mai, ʻoi aku ka lawe ʻia mai o nā hui electrode graphite kiʻekiʻe/ultra-mana. Coke nila ma ke ʻano he mea maka.
I ka makahiki 2021, ʻo ka hana kila kūloko he 1.037 biliona tone, ʻo ia hoʻi ka hana kila umu uila he emi ma mua o 10%. Ke hoʻolālā pū nei ke Kuhina ʻOihana a me ka ʻIke ʻIke e hoʻonui i ka hapa o ka hana kila umu uila i ʻoi aku ma mua o 15% i ka makahiki 2025. Ua wānana ka National Iron and Steel Association e hiki i ka 30% i ka makahiki 2050. E hiki i ka 60% i ka makahiki 2060. ʻO ka hoʻonui ʻana i ka lakio hana kila o nā umu uila e hoʻokele pololei i ke koi no nā electrodes graphite, a ʻoiaʻiʻo hoʻi, ke koi no ka nila coke.
