ʻO ka electrode maikaʻi onā pākahi lithium-ionʻO ka lithium iron phosphate material, he mea maikaʻi loa ia i ka hana palekana a me ke ola pōʻai.ʻO kēia kekahi o nā hōʻailona ʻenehana koʻikoʻi o ka pā uila.Hiki ke hoʻokō ʻia ke ola o Lifepo4 me 1C e hoʻopiʻi ana a me ka hoʻokuʻu ʻana i ke ola pōʻaiapuni i 2000 mau manawa, ʻaʻole pahū ka puncture, ʻaʻole maʻalahi ke puhi a pahū i ka wā i hoʻonui ʻia.He mea maʻalahi ka hoʻohana ʻana i nā ʻāpana lithium iron phosphate cathode i ka nui o ka mana.
Lithium iron phosphate ma ke ʻano he mea cathode
ʻO ka pākaukau Lifepo4 e pili ana i kahi pākahi lithium-ion e hoʻohana ana i ka lithium iron phosphate ma ke ʻano he mea electrode maikaʻi.ʻO nā mea electrode maikaʻi o nā pā lithium-ion ka nui o ka lithium cobaltate, lithium manganate, lithium nickelate, nā mea ternary, lithium iron phosphate, a me nā mea like.I waena o lākou, ʻo ka lithium cobaltate ka mea electrode maikaʻi i hoʻohana ʻia i ka hapa nui o nā pā lithium-ion.Ma ke kumu, ʻo ka lithium iron phosphate he hana hoʻopili a deintercalation.Ua like kēia kumumanaʻo me ka lithium cobaltate a me ka lithium manganate.
nā pono pākaukau lifepo4
1. Kiʻekiʻe ka hoʻouka a me ka hoʻokuʻu pono
ʻO ka pākaukau Lifepo4 kahi pākahi lua lithium-ion.ʻO kekahi kumu nui no nā pihi mana.Loaʻa iā ia nā pōmaikaʻi nui ma mua o nā pila NI-MH a me Ni-Cd.He kiʻekiʻe ka pākaukau ʻo Lifepo4 a hoʻokuʻu i ka pono, a ʻo ka hoʻopiʻi a me ka hoʻokuʻu ʻana hiki ke piʻi ma luna o 90% ma lalo o ke ʻano o ka hoʻokuʻu ʻana, ʻoiai ʻo ka pākaukau lead-acid ma kahi o 80%.
2. lifepo4 pākaukau kiʻekiʻe palekana hana
ʻO ka palapala PO i loko o ka lithium iron phosphate crystal he paʻa a paʻakikī ke hoʻoheheʻe ʻia, ʻaʻole e hāʻule a wela paha e like me ka lithium cobaltate a i ʻole e hana i kahi mea oxidizing ikaika a hiki i kahi wela kiʻekiʻe a i ʻole overcharge, a no laila he palekana maikaʻi. i ka hana maoli. , He wahi liʻiliʻi o ka hāpana i ʻike ʻia he ʻano wela i ka acupuncture a i ʻole ka hoʻāʻo pōkole pōkole, akā ʻaʻohe hanana pahū.I ka hoʻokolohua overcharge, ua hoʻohana ʻia kahi uku kiʻekiʻe-voltage i ʻoi aku ke kiʻekiʻe ma mua o ka uila hoʻokuʻu ponoʻī, a ua ʻike ʻia aia nō kahi hanana Explosion.Eia nō naʻe, ua hoʻomaikaʻi maikaʻi ʻia kona palekana overcharge i hoʻohālikelike ʻia i ka pākaukau lithium cobalt oxide wai electrolyte maʻamau.
3. Lifepo4 pākaukau lōʻihi pōʻaiapuni ola
ʻO ka pākaukau Lifepo4 e pili ana i kahi pākahi lithium-ion e hoʻohana ana i ka lithium iron phosphate ma ke ʻano he mea electrode maikaʻi.He 300 mau manawa ka lōʻihi o ke ola lead-acid, a ʻo ka mea kiʻekiʻe loa he 500 manawa.ʻO ka lithium iron phosphate power battery he ola pōʻai ma mua o 2000 mau manawa, a hiki ke hoʻohana ʻia ka uku maʻamau (5-hola helu) a hiki i 2000 mau manawa.ʻO ke ʻano like ʻole o ka pākaukau lead-acid he "hapalua makahiki hou, hapalua makahiki kahiko, mālama a mālama ʻia no ka hapalua makahiki", a hiki i 1 ~ 1.5 mau makahiki, a ua hoʻohana ʻia ka pākaukau lifepo4 ma lalo o nā kūlana like, e ola ke ola theoretical. hiki i 7-8 makahiki.Ke noʻonoʻo nei i ka laulā, ʻoi aku ka nui o ke kumu kūʻai o ka hana ma mua o ʻehā mau manawa ma mua o ʻehā mau manawa ma mua o nā pākī lead-acid.Hiki ke hoʻopiʻi a hoʻokuʻu ʻia me ka 2C kiʻekiʻe o kēia manawa.Ma lalo o ke kauā kūikawā, hiki ke hoʻopiha piha ʻia ka pākaukau i loko o 1.5 mau minuke o ka hoʻouka ʻana o 1.5C, a hiki i ka manawa hoʻomaka ke piʻi i 2C, akā ʻaʻohe hana like o ka pākaukau lead-acid.
4. Hana maikaʻi wela
Hiki ke piʻi ka mahana kiʻekiʻe o ka lithium iron phosphate i 350 ° C -500 ° C aʻo ka lithium manganate a me ka lithium cobaltate aia wale nō ma kahi o 200 ° C. ʻO ke ana wela hana ākea (-20C-+ 75C), me ke kū'ē kiʻekiʻe, lithium iron phosphate. Hiki i ka piko hoʻomehana uila ke hiki i 350 °C-500 °C, aʻo ka lithium manganate a me ka lithium cobalt oxide wale nō ma 200 °C.
5. Lifepo4 pākaukau Kiʻekiʻe
ʻOi aku ka nui o kona mana ma mua o nā pākahi maʻamau (lead-acid, etc.).ʻO ka mana monomer he 5AH-1000AH.
6. ʻAʻohe hopena hoʻomanaʻo
Ke hana nei nā pākaukau rechargeable ma lalo o nā kūlana i hoʻopau pinepine ʻole ʻia, a e hāʻule koke ka mana ma lalo o ka mana helu.Kapa ʻia kēia hanana ka hopena hoʻomanaʻo.ʻO ka hoʻomanaʻo e like me ka nickel-metal hydride a me ka nickel-cadmium batteries, akā ʻaʻole i loaʻa kēia hanana i ka lifepo4 battery, ʻaʻohe mea o ke ʻano o ka pākaukau, hiki ke hoʻohana ʻia me ka uku, ʻaʻole pono e hoʻokuʻu a hoʻouka hou.7.Māmā o ka pākaukau lifepo4
ʻO ka pākaukau lifepo4 o ka mana kikoʻī like ʻo 2/3 o ka nui o ka pākaukau lead-acid, a ʻo ke kaumaha he 1/3 o ka pākaukau lead-acid.
8. ʻO nā pila Lifepo4pili kaiapuni
Manaʻo ʻia ʻo ka pākaukau ʻaʻole i loaʻa i nā metala kaumaha a me nā metala liʻiliʻi (ʻo Ni-MH batteries e koi i nā metala liʻiliʻi), non-toxic (SGS certified), non-polluting, e like me nā lula ʻo European RoHS, he palapala ʻōmaʻomaʻo piha. .No laila, ʻo ke kumu i makemake nui ʻia ai nā pā lithium e ka ʻoihana i ka noʻonoʻo ʻana i ke kaiapuni.No laila, ua hoʻokomo ʻia ka pākaukau i loko o ka papahana hoʻomohala ʻenehana kiʻekiʻe ʻo "863" i ka wā o ka manawa "Tenth Five-Year Plan" a ua lilo ʻo ia i kākoʻo kī nui a me ka papahana hoʻomohala hoʻoikaika.Me ke komo ʻana o Kina i ka WTO, e piʻi wikiwiki ana ka nui o nā kaʻa kaʻa uila i Kina, a ua koi ʻia nā kaʻa uila e komo i ʻEulopa a me ʻAmelika Hui Pū ʻIa me nā pākaukau ʻaʻole haumia.ʻO ka hana o ka pākaukau lithium-ion e hilinaʻi nui i nā mea maikaʻi a maikaʻi ʻole.ʻO Lithium iron phosphate kahi mea pākahi lithium i ʻike ʻia i nā makahiki i hala iho nei.ʻAʻole hiki ke hoʻohālikelike ʻia kāna hana palekana a me ke ola pōʻai i nā mea ʻē aʻe.ʻO nā hōʻailona ʻenehana koʻikoʻi o ka pākaukau.Loaʻa i ka pākaukau Lifepo4 nā mea maikaʻi o nā mea ʻawaʻawa ʻole, ʻaʻole haumia, hana palekana maikaʻi, kahi ākea o nā mea maka, nā kumukūʻai haʻahaʻa, a me ke ola lōʻihi.He mea cathode kūpono no ka hanauna hou onā pākahi lithium-ion.
