Hōʻike ka Lithium iron phosphate maikaʻi i ke kūpaʻa wela maikaʻi, ka hilinaʻi palekana, ka palekana o ke kaiapuni kalapona haʻahaʻa, ʻo ia ka mea maikaʻi maikaʻi o nā modules nui. Eia naʻe, he haʻahaʻa ka pilestance density o ka lithium iron phosphate positive electrode material, a ʻaʻole kiʻekiʻe ka nui o ka ikehu, ʻoi aku ka palena o ka noi. No ka hoʻohana ʻana i nā palena o ka lithium iron phosphate positive electrode material, hiki i nā limahana kūpono ke hoʻomaikaʻi i ka conductivity o ia mau mea ma ke ʻano o ka doping i nā cation metala kiʻekiʻe kahi e doped ʻia ai nā cations metala kiʻekiʻe.

Ma hope o ka manawa o ka hoʻomohala ʻana, hoʻomohala ʻia ka lithium iron phosphate, a hoʻohana nui ʻia ia i nā kula he nui, e like me nā ʻāpana kaʻa uila, nā kahua paʻa uila, nā lako mana kelepona, nā kahua mālama mālama ikehu, etc. Hoʻohana nui ʻia ka Lithium iron phosphate positive material i ke kahua o nā kaʻa uila, ʻoi aku ka mea kaʻa uila, ʻoi aku ka nui o ka mea holo uila, ʻoi aku ka nui o ka mea holo uila, ʻoi aku ka maikaʻi o ka pono kūʻokoʻa, ʻo ia hoʻi nā haʻahaʻa haʻahaʻa o ke ola pōʻaiapuni, waiwai i nā kumuwaiwai, nā kumukūʻai haʻahaʻa. Eia naʻe, ʻo ka nele o ka olivine crystal structure o ka lithium iron phosphate positive electrode material, e like me ka haʻahaʻa uila conductivity, liʻiliʻi lithium ion diffusion coefficient, etc.

, ka mea e hoʻohaʻahaʻa ai i ka ikehu haʻahaʻa, ka maikaʻi ʻole o ka mahana a me ka hana hewa, etc. e kaupalena &39;ia ma ka wahi noi. E hoʻomaikaʻi i kona mau hemahema.

I kēia mau makahiki i hala iho nei, ua ʻike ka mākeke pākahi lithium-ion ikaika o koʻu ʻāina i ka piʻi ʻana o ka pahū, ʻo ka ʻenehana ʻenehana kāna kumu hoʻokūkū. I kēia manawa, he mea nui ka mana lithium-ion me ka lithium iron phosphate ion batteries, lithium-manganese acid ion batteries and three-dimensional ion battery. Hoʻohālikelike ka Papa 2 i ka hana ʻana o nā ʻano pākaukau lithium-ion, kahi DOD kahi hohonu hohonu hohonu (Discharge).

Kākoʻo ʻo Lithium iron phosphate ion i koʻu ʻāina i ka ʻoihana lithium-ion ʻoihana ʻoihana hapa-Wanjiang Mountain, a he nui nā mea maikaʻi i nā ʻokoʻa like ʻole: ʻoi aku ka lōʻihi o ka pā lithium iron phosphate ion, haʻahaʻa haʻahaʻa wela, maikaʻi ka thermal stability, a ʻo ka lithium iron phosphate Ion batteries no ka palekana kaiapuni. Hoʻohana ʻia ka pākaukau Lithium phosphate ion i nā kaʻa kaʻa uila me ke kumu kūʻai haʻahaʻa a me ka hana paʻa, a ke hōʻike nei ka mākeke i kahi kūlana kiʻekiʻe. Loaʻa ka waiwai i ka palekana maikaʻi, ke ola pōʻai lōʻihi, ke kumu kūʻai haʻahaʻa, etc.

E like me ka ʻike ma luna, hāʻawi mākou i nā manaʻo e ana i nā kumu kūʻai: 1) ʻO ka nui o ka pā uila ma kahi o 50% kiʻekiʻe ma mua o ka ikehu.

Ke hoʻomau ʻia ka nui o ka hoʻopiʻi, hoʻemi ʻia ka leo ma mua o hoʻokahi hapakolu, no laila e hoʻokele ʻia ka uhi ʻili alumini. Ke kumukūʻai Pack, me ka manaʻo he 33% ka emi ʻana 2) ʻO ka ikehu, ka mea hana, ke kumukūʻai hana, a me ka emi ʻana o ka BMS ma muli o ke kaʻina hana optimization a me ka hōʻemi ʻana o nā ʻāpana, me ka manaʻo ʻana he 20% ​​hōʻemi 3) manaʻo hou aʻe e hiki ke hoʻokuʻu ʻia nā kumu waiwai (me ka electrode maikaʻi, electrode maikaʻi ʻole, diaphragm, electrolyte, copper foil , Methyl, pahu pahu pahu), hiki ke hāʻule ke kumu kūʻai 60. yuan / WH i 24.

3% i ka 0.527 yuan / WH. 4) E noʻonoʻo hou aʻe i ka palena waiwai nui o ka hui e hiki ke hoʻohana ʻia no ka loaʻa ʻana o nā kumukūʻai kūʻai maoli, e like me ka mea i hōʻike ʻia ma ke Kiʻi 35, ʻo ke ʻano o ka pahi a me ke ʻano CTP e alakaʻi wale i nā kaʻa kalepa, ʻoiai ua hoʻolaha ʻia ʻo BYD, e hoʻohana ʻia ke ʻano pākaukau ma Han.

Ke manaʻoʻiʻo nei mākou ua hoʻohana ʻia ʻo BYD i kā mākou kaʻa kaʻa ponoʻī, ʻo ia ka mea e uhaʻi ai i ka loiloi ʻenehana maʻamau: ke holomua pinepine nei nā ʻenehana hou i nā kaʻa kalepa, a ʻoi aku ka makaʻala o nā kaʻa kaʻa. Ke hoʻohana nei ʻo BYD i nā ʻeke ʻeke ma luna o kāna kaʻa ponoʻī, ʻaʻole kānalua i ka wikiwiki o ka hoʻolaha ʻana i ke kaʻa kaʻa. ʻO kaʻoiaʻiʻo, ua like ke ʻano o ka pā a me ke ʻano CTP, a no ka hoʻohaʻahaʻa hou ʻana i nā kumukūʻai, ʻoiai ka nui o ka pākahi monomer, a makemake ʻia ka lithium iron phosphate.

Ma muli o ka 2019, ua nui nā mea kanu mīkini laina mua e hoʻohana i ke ʻano CTP no ka hoʻāʻo ʻana, no laila ke manaʻo nei e hoʻohana kēia ʻenehana i kēia ʻenehana i 2020. E like me nā manaʻo i luna, helu mākou i 10 mau mika a ʻoi aku paha, ua hoʻemi ʻia ke kumukūʻai pākaukau e 30%, a ua hoʻemi ʻia ke kumukūʻai pākaukau mai 225,000 a i 158,000. Inā ʻaʻohe kālā, hiki ke mālama ʻia ka palena o ka loaʻa kālā.

Manaʻo mākou e hoʻonui hou ʻia ka pākaukau o 2020 phosphate&39;s tamite i nā kaʻa kalepa. Mai ka hiʻohiʻona o ka hoʻopukapuka kālā, ua kau ʻia ka upstream phosphite, a me ka hoʻomaikaʻi maikaʻi ʻana o ke kaʻa ʻoihana i lalo. No ka mea ua hala ka upstream o ka lithium iron phosphate i ʻekolu makahiki shuffle, ʻoi aku ka kiʻekiʻe o ka ʻoihana.

I ke kaulahao ʻoihana, inā hiki ʻoe i nā mea hoʻolako 10, ua kiʻekiʻe loa ia i ka noʻonoʻo ʻana, a aia wale nō nā mea hoʻolako 3-4 o nā ʻaoʻao ʻekolu. No laila ke manaʻoʻiʻo nei mākou e pōmaikaʻi ka leadload. Manaʻo: German nano, Guoxuan high-tech, BYD a me Yutong Bus.
