E hoʻomaka ana mai 2022, ua piʻi nui ka noi o ka mākeke no nā huahana mālama ikehu ma muli o ka nele o ka ikehu a me ka piʻi nui ʻana o nā kumukūʻai uila ma nā ʻāina he nui a puni ka honua. Ma muli o ke kiʻekiʻe o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana a me ke kūpaʻa maikaʻi,nā pākahi lithiumua manaʻo ʻia ma ke ao holoʻokoʻa ʻo ia ka koho mua no nā mea mālama ikehu hou. Ma ke kahua hoʻomohala hou, he hana koʻikoʻi ia no nā hoa hana a pau o ka ʻoihana keleawe keleawe e neʻe mau i mua a hoʻoikaika hou i ka hoʻololi ʻana o ka huahana a me ka hoʻonui ʻana e hoʻokō i ka noi mākeke hou a hoʻokō i ka hoʻomohala kiʻekiʻe. ʻAʻole paʻakikī ka loaʻa ʻana o ka mākeke pākaukau lithium i kēia lā, ke ulu wikiwiki nei ke koi no ka mālama ʻana i ka mana, ke ʻano maʻamau o ka ʻemi ʻana o ka pākaukau, a ua lilo nā huahana pāpaʻi keleawe keleawe lahilahi i "huahana pahū".
ʻO Lithium copper foil ka pōkole nopākaukau lithium-ioncopper foil, i hoʻohana ʻia ma ke ʻano he mea no ka mea ʻohi anode o nā pā lithium-ion a no ka ʻāpana koʻikoʻi o ka foil keleawe electrolytic. He ʻano metala keleawe ia i hana ʻia e ke ʻano electrolytic me ka mālama ʻana i ka ʻili, a ʻo ia ka hoʻohālikelike maʻamau o ka pahu keleawe lithium mānoanoa. Hiki ke hoʻokaʻawale ʻia ka pahu pahu pahu Li-ion e ka mānoanoa i loko o ka ʻāpana keleawe lahilahi (12-18 microns), ka pahu keleawe ultra-thin (6-12 microns) a me ka pahu keleawe ultra-thin (6 microns a lalo). Ma muli o ke koi nui o ka ikehu o nā kaʻa ikehu hou, hoʻohana ʻia nā pihi mana e hoʻohana i ka pepa keleawe ultra-thin a lahilahi loa me ka mānoanoa lahilahi.
Maikaʻi nonā pākahi lithium maname nā koi koi ikaika nui, ua lilo ka lithium copper foil i hoʻokahi o nā holomua. Ma lalo o ka manaʻo e hoʻololi ʻole nā ʻōnaehana ʻē aʻe, ʻoi aku ka lahilahi a me ka māmā o ka pahu keleawe i hoʻohana ʻia i nā pā lithium, ʻoi aku ka kiʻekiʻe o ka nui o ka ikehu. Ma keʻano he pahu lithium keleawe ma waena o ke kaulahao o ka ʻoihana, hoʻomohala ʻia ka hoʻomohala ʻana o ka ʻoihana e ka upstream raw material a me nā pā lithium lalo. ʻO nā mea waiwai i uka e like me ke keleawe a me ka sulfuric acid he mau waiwai nui me ka lako lako akā ke loli pinepine nei ke kumu kūʻai; Hoʻopili ʻia nā pā lithium i lalo e ka hoʻomohala ʻana i nā kaʻa ikehu hou a me ka mālama ʻana i ka ikehu. I ka wā e hiki mai ana, pōmaikaʻi nā kaʻa ikehu hou mai ka hoʻolālā kalapona kūʻokoʻa aupuni, a ke manaʻo ʻia nei ka piʻi nui ʻana o ka kaulana, a e ulu wikiwiki ka noi no nā pā lithium-ion mana. Ke ulu wikiwiki nei ka mālama ʻana i ka ikehu kemika o Kina, a me ka ulu ʻana o ka mana makani, photovoltaic a me nā ʻoihana ʻē aʻe, e ulu wikiwiki ana ka mālama ʻana i ka ikehu electrochemical o Kina. Manaʻo ʻia ʻo 57.4% mai ka makahiki 2021-2025 ka nui o ka ulu ʻana o ka hoʻoulu ʻana o ka ikehu electrochemical.
Me ka hui pū ʻana o nā ʻoihana pākaukau a me nā mea hana keleawe keleawe, ʻo Kina ka lithium battery copper foil i mua o ka honua ma ke ʻano o ka māmā a me ka lahilahi. I kēia manawa, ʻo ka pahu keleawe no nā pā lithium home he 6 microns a me 8 microns. I mea e hoʻomaikaʻi ai i ka nui o ka ikehu o ka pākaukau, ma kahi o ka mānoanoa, ka ikaika tensile, elongation, ka wela a me ka pale ʻana i ka corrosion he mau hōʻailona ʻenehana koʻikoʻi. Ua lilo ʻo 6 microns a me nā ʻāpana keleawe ʻoi aku ka manaʻo o ka hoʻolālā o nā mea hana nui o ka home, a i kēia manawa, 4 microns, 4.5 microns a me nā huahana thinner i hoʻohana ʻia i nā ʻoihana poʻo e like me Ningde Time a me China Innovation Aviation.
He paʻakikī ka hoʻopuka maoli ʻana i ka mana nominal, a ʻo ka nui o ka hoʻohana ʻana i ka nui o ka nui o ka hoʻohana ʻana i ka nui o ka ʻoihana lithium copper foil ma kahi o 80%, me ka noʻonoʻo ʻana i ka hiki ʻole ke hiki ke hana nui ʻia. ʻO 6 micron copper foil a ma lalo paha e hauʻoli i ka mana kūʻai kiʻekiʻe a me ka loaʻa kālā kiʻekiʻe ma muli o ka paʻakikī o ka hana ʻana. Ke noʻonoʻo nei i ke kumu kūʻai kumu kūʻai o ke kumu kūʻai keleawe + ka uku hana no ka lithium copper foil, ʻo ka uku hana o 6 micron copper foil he 5.2 miliona yuan / ton (me ka ʻauhau), ʻo ia ka 47% kiʻekiʻe ma mua o ka uku hana o 8 micron copper foil.
Loaʻa ka pōmaikaʻi mai ka hoʻomohala wikiwiki ʻana o nā kaʻa ʻenehana hou o Kina a me ka ʻoihana pākaukau lithium, he alakaʻi honua ʻo Kina i ka hoʻomohala ʻana i ka pahu lithium copper foil, e uhi ana i ka pepa keleawe lahilahi, ka pahu keleawe ultra-thin a me ka foil keleawe lahilahi. Ua lilo ʻo Kina i mea hana nui loa o ka honua i ka lithium copper foil. Wahi a CCFA, he 229,000 tons ka nui o ka lithium copper foil o Kina i 2020, a ke manaʻo nei mākou he 65% ka mākeke o Kina i ka honua lithium copper foil.
Māhele Nordic: ua hoʻomaka hou ke alakaʻi o ka lithium copper foil i ka ulu ʻana, ka mea nui i ka hoʻomohala ʻana, ka hana ʻana a me ke kūʻai aku ʻana i ka foil keleawe electrolytic no nā pā lithium-ion, ʻo nā huahana electrolytic copper foil nui ka 4-6 micron ʻoi loa ka lahilahi lithium copper foil, 8-10 micron ultra-thin lithium copper foil, 9-70 micron high-performance electronic circuit copper foil, 105-500 micron ultra-thick electrolytic copper foil, etc., i ka home mua e loaa 4.5 micron a me 4 micron loa lahilahi lithium copper foil i loko. hana nui.
ʻO Jiayuan Technology: Ke komo nui nei i ka lithium copper foil, ke hoʻomau nei ka ulu ʻana o ka hana e hiki mai ana, e hana nui ana i ka hana ʻana a me ke kūʻai aku ʻana i nā ʻano like ʻole o ka pahu keleawe electrolytic kiʻekiʻe no nā pā lithium-ion mai 4.5 a 12μm, hoʻohana nui ʻia i ka lithium-ion. nā pila, akā he helu liʻiliʻi o nā noi ma PCB. Ua hoʻokumu ka hui i nā pilina lōʻihi me nā mea hana pākaukau lithium-ion nui a lilo i mea hoʻolako kumu o kā lākou lithium copper foil. Ke komo nui nei ka hui i ka lithium copper foil a ke alakaʻi nei i ka noiʻi a me ka hoʻomohala ʻana i nā huahana, a i kēia manawa ua hāʻawi ʻo ia i ka 4.5 micron ʻoi aku ka lahilahi lithium copper foil i nā mea kūʻai i ka hui.
Wahi a nā papahana keleawe keleawe a nā ʻoihana nui a me ka holomua o kā lākou hana hana, hiki ke hoʻomau ʻia ke ʻano o ka hoʻolako paʻa ʻana o ke keleawe keleawe ma 2022 ma lalo o ka ulu wikiwiki o ka noi, a ke manaʻo ʻia nei ka uku hana o ka lithium copper foil e mālama i kahi kiʻekiʻe. pae. E ʻike ʻo 2023 i kahi hoʻomaikaʻi nui ma ka ʻaoʻao hoʻolako, a e hoʻonui hou ka ʻoihana.
