Wahi a kekahi nūhou i hoʻokuʻu ʻia e ka Electronic Information Department o ka Ministry of Industry and Information Technology ma Dekemaba 10, i mea e hoʻoikaika hou ai i ka hoʻokele ʻana i ka ʻoihana pākaukau lithium-ion a hoʻoikaika i ka hoʻololi a me ka hoʻomaikaʻi ʻana i ka ʻoihana a me ka holomua ʻenehana, ka Ua hoʻokele manawaleʻa ʻo Ministry of Industry and Information Technology i ka "Lithium-ion Battery Industry Specification Conditions" a me ka "Lithium-ion Battery Industry Specification Announcement Management" Ua hoʻoponopono hou ʻia nā ana a ke hoʻolaha ʻia nei. ʻO ka "Lithium-ion Battery Industry Specification Conditions (2018 Edition)" a me nā "Interim Measures for the Administration of Lithium-ion Battery Industry Specification Announcements (2018 Edition)" (Announcement No. 5, 2019 of the Ministry of Industry and Information Technology. ) e hoʻopau ʻia i ka manawa like.
Manaʻo ʻo "Lithium-ion battery industry standard condition (2021)" e alakaʻi i nā ʻoihana e hōʻemi i nā papahana hana e hoʻonui wale i ka mana hana, hoʻoikaika i ka ʻenehana ʻenehana, hoʻomaikaʻi i ka maikaʻi o ka huahana, a hoʻemi i nā kumukūʻai hana. Pono nā hui pākaukau Lithium-ion e hoʻokō i kēia mau kūlana: ma ka Lepupalika Kanaka o Kina Ua hoʻopaʻa inoa ʻia a hoʻokumu ʻia ma ke kānāwai ma ka ʻāina, me ke ʻano kūʻokoʻa kūʻokoʻa; hana kūʻokoʻa, kūʻai aku a me nā lawelawe lawelawe o nā huahana pili i ka ʻoihana pākaukau lithium-ion; ʻAʻole emi nā lilo R&D ma lalo o 3% o ka loaʻa kālā nui o ka ʻoihana no ka makahiki, a ua paipai ʻia nā hui e loaʻa i nā ʻoihana R&D kūʻokoʻa ma luna a i ʻole ka pae panalāʻau. loaʻa i nā huahana nui nā patent ʻenehana; ʻaʻole e emi ka huahana maoli o ka makahiki i hala i ka manawa o ka hoʻolaha ʻana ma lalo o 50% o ka mana hana maoli o ka makahiki hoʻokahi.
ʻO ka "Lithium-ion Battery Industry Standard Conditions (2021)" e koi pū i nā hui e hoʻohana i ka ʻenehana kiʻekiʻe, mālama i ka ikehu, pili i ke kaiapuni, palekana a paʻa, a me nā kaʻina hana a me nā lako hana akamai loa, a hoʻokō i nā koi penei: 1. Lithium-ion pono nā hui pākaukau ʻO ka hiki ke nānā i ke kūlike o ka electrode ma hope o ka uhi ʻana, a ʻo ka pololei o ka mana o ka electrode coating mānoanoa a me ka lōʻihi ʻaʻole i emi iho ma mua o 2μm a me 1mm; pono e loaʻa iā ia ka ʻenehana hoʻomaloʻo electrode, a ʻaʻole pono e emi ka pololei o ka mana o ka wai ma mua o 10ppm. 2. Pono nā hui pākaukau Lithium-ion i hiki ke hoʻomalu i nā kūlana kaiapuni e like me ka mahana, ka haʻahaʻa a me ka maʻemaʻe i ka wā o ke kaʻina hana; pono iā lākou ke ʻike i nā hoʻāʻo kiʻekiʻe-voltage kūloko kūloko (HI-POT) ma ka laina ma hope o ka hui ʻana o ka pākaukau. 3. Pono nā ʻoihana pākaukau lithium-ion i hiki ke hoʻomalu i ka volta kaapuni hāmama a me ke kūpaʻa kūloko o nā cell hoʻokahi, a ʻaʻole e emi ka pololei o ka mana ma lalo o 1mV a me 1mΩ; pono iā lākou ke nānā i ka hana o ka papa pale pākaukau ma ka pūnaewele.
Ma nā ʻōlelo o ka hana huahana, ua hana ka "Lithium-ion Battery Industry Specification Conditions (2021 Edition)" i kēia mau koi:
