Mai ka hoʻomaka ʻana o ke kenekulia 21, me ka piʻi ʻana o nā mea uila uila e like me nā smartphones, nā papa, nā mea hiki ke hoʻohana a me nā drones, ke koi nonā pākahi lithiumua ʻike i kahi pahū i ʻike ʻole ʻia.Ke ulu nei ka noi honua no nā pā lithium ma kahi o 40% a 50% i kēlā me kēia makahiki, a ua hana ka honua ma kahi o 1.2 biliona mau mea hoʻoili kaʻa kaʻa hou a ʻoi aku ma mua o 1 miliona mau pihi mana no nā kaʻa uila, 80% o ia mau mea mai ka Mākeke Pākē.Wahi a Gartner data: Ma ka makahiki 2025, hiki i ka 5.7 billion Ah ka nui o ka pākaukau lithium honua, me ka nui o ka ulu ʻana o ka makahiki he 21.5%.Me ka holomua o ka ʻenehana a me ka hoʻokele kumu kūʻai, ua lilo ka pākaukau Li-ion i kumu kūʻai hoʻokūkū koʻikoʻi i ka pākaukau lead-acid kuʻuna i loko o ka pā uila mana kaʻa hou.
1. ʻIke ʻenehana
Ke hoʻomau nei ka hoʻomohala ʻana o ka ʻenehana ʻenehana lithium, mai nā mea ternary i hala a hiki i ke kiʻekiʻe o ka ikehu lithium iron phosphate material, i kēia manawa ke hoʻololi i ka lithium iron phosphate a me nā mea ternary, a ʻo ke kaʻina cylindrical ka mea nui.Ma ke kahua o ka mea kūʻai uila, cylindrical lithium iron phosphate batteries e hoʻololi mālie ana i ka cylindrical a me ka square lithium iron phosphate batteries;mai nā noi pākaukau mana, mai ka hoʻomaka ʻana o ka hoʻohana ʻana a hiki i kēia lā, ke piʻi nei ka nui o nā noi pā uila mana i kēlā me kēia makahiki.ʻO ka nui o nā ʻāina nui o ka honua i kēia manawa e pili ana i ka 63%, e manaʻo ʻia e hōʻea ma kahi o 72% i 2025. I ka wā e hiki mai ana, me ka holomua ʻenehana a me ka hoʻokele kumu kūʻai, manaʻo ʻia e ʻoi aku ka paʻa o ka huahana pākaukau lithium a hōʻike i kahi mākeke ākea. ākea.
2. Mākeke ʻĀina
ʻO ka pākaukau Li-ion ka mea i hoʻohana pinepine ʻia i ke ʻano o ka pā uila a loaʻa kahi ākea o nā noi ma ke kahua o nā kaʻa ikehu hou, a ʻo ke koi mākeke no ka pā Li-ion nui.ʻAe, piʻi 44.2% makahiki-ma-makahiki.Ma waena o lākou, ʻo ka hana ʻana o Ningde Times he 41.7%;Ua helu ʻo BYD i ka lua, me 18.9% o ka hana.Me ka hoʻomau ʻana o ka hoʻonui ʻana i ka mana hana o ka ʻoihana, ke piʻi nui nei ka hoʻokūkū hoʻokūkū o ka ʻoihana pākaukau lithium, ʻo Ningde Times, BYD a me nā ʻoihana ʻē aʻe e hoʻomau i ka hoʻonui ʻana i kā lākou māhele mākeke ma muli o ko lākou pono ponoʻī, ʻoiai ua hōʻea ʻo Ningde Times i kahi hui hoʻolālā me. Samsung SDI a ua lilo ʻo ia i hoʻokahi o nā mea hoʻolako uila mana nui o Samsung SDI;Ke hoʻomau nei ʻo BYD i ka hoʻonui ʻana i kāna hoʻopukapuka ʻana ma ke kahua o nā pihi mana ma muli o kāna mau pono ʻenehana, a i kēia manawa i ka hoʻolālā ʻana o ka mana hana o ka BYD i ke kahua o nā pihi mana ua hoʻomaikaʻi mālie a komo i ke kahua o ka hana nui;Loaʻa i ka BYD kahi ʻoi aku ka hohonu a me ka piha piha o nā mea ʻenehana lithium i luna, kona kiʻekiʻe nickel ternary lithium, nā huahana graphite system i hiki ke hoʻokō i nā koi o ka hapa nui o nā ʻoihana pākaukau lithium.
3.ʻO ka nānā ʻana i ka hoʻolālā ʻana o nā mea pākaukau lithium
Mai ka hana kemika, aia ka nui o nā mea cathode (me nā mea lithium cobaltate a me nā mea lithium manganate), nā mea electrode maikaʻi ʻole (me ka lithium manganate a me ka lithium iron phosphate), electrolyte (me ka sulfate solution a me ka nitrate solution), a me ka diaphragm (me LiFeSO4 a me LiFeSO4. LiFeNiO2).Mai ka hana waiwai, hiki ke hoʻokaʻawale i nā mea electrode maikaʻi a maikaʻi ʻole.Hoʻohana maʻamau nā ʻona Lithium-ion i ka cathode e hoʻomaikaʻi i ka pono o ka hoʻouka ʻana, ʻoiai e hoʻohana ana i ka lithium ma ke ʻano he cathode;electrode maikaʻi ʻole e hoʻohana ana i ka nickel-cobalt-manganese alloy;ʻO nā mea cathode ka nui o NCA, NCA + Li2CO3 a me Ni4PO4, etc.;ʻO ka electrode maikaʻi ʻole ma ke ʻano he puʻupuʻu ion i loko o ka mea cathode a ʻo ka diaphragm ka mea koʻikoʻi loa, pili pono kona ʻano i ka hana ʻana o nā pā lithium-ion.I mea e loaʻa ai ka uku kiʻekiʻe a hoʻokuʻu i ka ikehu kūikawā a me ke ola lōʻihi, pono e loaʻa i ka lithium nā hiʻohiʻona kiʻekiʻe a me nā hiʻohiʻona ola lōʻihi.Hoʻokaʻawale ʻia nā electrodes Lithium i nā ʻona paʻa, nā ʻāpana wai a me nā ʻāpana polymer e like me ka mea, ʻo ia ka polymer fuel cell he ʻenehana maʻamau me nā uku kumukūʻai a hiki ke hoʻohana ʻia i nā kelepona kelepona a me nā mea kūʻai uila ʻē aʻe;ka mana paʻa ma muli o ke kiʻekiʻe o ka ikehu a me ke kumu kūʻai haʻahaʻa o ka hoʻohana, kūpono no ka mālama ʻana i ka ikehu a me nā māla ʻē aʻe;a me ka mana polymer ma muli o ka haʻahaʻa haʻahaʻa o ka ikehu a me ke kumu kūʻai haʻahaʻa akā i kaupalena ʻia ke alapine o ka hoʻohana ʻana, kūpono no ka pā pākaukau lithium.Hiki ke hoʻohana ʻia nā kinikini wahie Polymer i nā kelepona kelepona, nā kamepiula kamepiula a me nā kiʻi kamepiula;Aia ka ʻenehana ʻenehana paʻa i kēia manawa i ka pae hoʻokolohua.
4.Manufacturing kaʻina hana a me ke kumu kūʻai
Hoʻokumu ʻia nā ʻeke uila lithium mea kūʻai aku me ka hoʻohana ʻana i nā cell voltage kiʻekiʻe, ka mea nui i haku ʻia me nā mea electrode maikaʻi a maikaʻi ʻole a me nā mea diaphragm.ʻO ka hana a me ke kumukūʻai o nā mea cathode ʻokoʻa ʻokoʻa loa, kahi ʻoi aku ka maikaʻi o ka hana ʻana o nā mea cathode, ʻoi aku ka haʻahaʻa o ke kumukūʻai, ʻoiai ʻoi aku ka maikaʻi o ka hana ʻana o nā mea diaphragm, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.Wahi a ka China Industry Information Network, hōʻike ka mea kūʻai aku i nā mea uila lithium maikaʻi a maikaʻi ʻole nā mea electrode no 50% a 60% o ka huina kālā.Hana ʻia ka mea maikaʻi i nā mea ʻino akā ʻoi aku ka nui o kāna kumukūʻai ma mua o 90%, a me ka piʻi ʻana o ke kumukūʻai kūʻai waiwai maikaʻi ʻole, ua piʻi mālie ke kumukūʻai huahana.
5.Equipment e kākoʻo ana i nā koi o nā mea hana
Ma keʻano holoʻokoʻa, ʻo nā mea hana hoʻohui i nā pahu lithium i loko o ka mīkini hoʻoheheʻe ʻia, ka mīkini laminating, a me ka laina hoʻopau wela, a me nā mea ʻē aʻe. oiai he sila maikai.E like me ka koi o ka hana, hiki ke hoʻolako ʻia me nā mold e like me ka ʻike ʻana i ka ʻoki pololei ʻana o nā mea hoʻopihapiha (core, negative material, diaphragm, etc.) a me ka envelopp.Mīkini hoʻopaʻa: Hoʻohana nui ʻia kēia mea hana e hoʻolako i ke kaʻina hana hoʻopaʻa ʻana no ka pā uila lithium mana, ʻo ia ka nui o nā ʻāpana nui ʻelua: ka wikiwiki kiʻekiʻe a me ke alakaʻi wikiwiki.
