Ua hoʻolaha ʻo Tesla's 2021 Q3 hōʻike i kahi hoʻololi i nā pākahi LiFePO4 ma ke ʻano he maʻamau hou i kāna mau kaʻa.Akā, he aha ke ʻano o nā pākahi LiFePO4?
NEW YORK, NEW YORK, USA, Mei 26, 2022 /EINPresswire.com / — He ʻoi aku ka maikaʻi o lākou i nā pākahi Li-Ion?Pehea ka ʻokoʻa o kēia mau ʻaʻa mai nā ʻokoʻa ʻē aʻe?
Hoʻolauna i nā Bateri LiFePO4
ʻO ka pākaukau lithium iron phosphate (LFP) kahi pākaukau lithium-ion me ka wikiwiki o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana.ʻO ia kahi pākaukau e hoʻouka hou ʻia me LiFePO4 ma ke ʻano he cathode a me kahi electrode carbon graphitic me ke kākoʻo metala e like me ka anode.
He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka ikehu liʻiliʻi o nā pākahi LiFePO4 ma mua o nā ʻona lithium-ion a me nā haʻahaʻa haʻahaʻa haʻahaʻa.He haʻahaʻa ko lākou hoʻokuʻu haʻahaʻa me nā pihi ākea a ʻoi aku ka palekana ma mua o ka Li-ion.Ua ʻike ʻia kēia mau pākaukau ʻo nā pā lithium ferrophosphate.
ʻO ka mea i hana ʻia o nā Bateri LiFePO4
Na John B. Goodenough lāua ʻo Arumugam Manthiram nā Bateri LiFePO4 i haku.ʻO lākou kekahi o ka poʻe mua i hoʻoholo i nā mea i hoʻohana ʻia i nā pā lithium-ion.ʻAʻole kūpono nā mea anode no nā pākahi lithium-ion ma muli o ko lākou makemake no ka pōkole pōkole.
Ua ʻike nā kānaka ʻepekema ʻoi aku ka maikaʻi o nā mea cathode i ka hoʻohālikelike ʻana i nā cathodes pākahi lithium-ion.ʻIke nui ʻia kēia i nā ʻano pākaukau LiFePO4.Hoʻonui lākou i ka paʻa a me ka conductivity a hoʻomaikaʻi i nā ʻano ʻano ʻē aʻe.
I kēia mau lā, loaʻa nā pākahi LiFePO4 ma nā wahi āpau a loaʻa nā noi like ʻole, me ka hoʻohana ʻana i nā waʻa, nā ʻōnaehana solar, a me nā kaʻa.ʻAʻole kūʻai ʻia nā pila LiFePO4 a emi ke kumu kūʻai ma mua o ka nui o nā mea ʻē aʻe.ʻAʻohe mea ʻawaʻawa a ʻoi aku ka lōʻihi o ka mālama ʻana.
Nā ʻōlelo kikoʻī o ka pākaukau LFP -
ʻO ka hana o nā Pūnaehana Hoʻokele Batri ma nā Bateri LFP
Hoʻokumu ʻia nā pākahi LFP me nā pūnaewele pili wale;loaʻa iā lākou kahi ʻōnaehana e hōʻoia i ka noho ʻana o ka pākaukau i loko o nā palena palekana.Mālama ka ʻōnaehana hoʻokele pila (BMS), mālama, a nānā i ka pākaukau ma lalo o nā kūlana hana e hōʻoia i ka palekana a hoʻolōʻihi i ke ola pākaukau.
ʻO ka hana o nā Pūnaehana Hoʻokele Baterya i nā Bateri LFP -
ʻOiai ʻoi aku ka ʻoi aku o ka hoʻomanawanui ʻana o nā cell lithium iron phosphate, akā naʻe, hiki i ka overvoltage i ka wā o ka hoʻouka ʻana, e hōʻemi ana i ka hana.ʻO ka mea i hoʻohana ʻia i ka cathode hiki ke hōʻino a nalowale kona kūpaʻa.Hoʻoponopono ka BMS i ka hoʻopuka ʻana o kēlā me kēia cell a hōʻoia i ka mālama ʻana i ka volta kiʻekiʻe o ka pākaukau.
Ke hoʻohaʻahaʻa nei nā mea electrode, lilo ka Undervoltage i mea hopohopo nui.Inā hāʻule ka uila o kekahi kelepona ma lalo o kahi paepae i kuhikuhi ʻia, hoʻokaʻawale ka BMS i ka pila mai ke kaapuni.Hoʻohana ia ma ke ʻano he backstop i kahi kūlana overcurrent a e pani i kāna hana i ka wā pōkole.
LiFePO4 Batteri vs. Lithium-Ion Battery
ʻAʻole kūpono nā pila LiFePO4 no nā mea hoʻohana e like me nā wati.Aia lākou ma lalo o kahi haʻahaʻa haʻahaʻa haʻahaʻa ma mua o nā ʻāpana lithium ʻē aʻe.Eia nō naʻe, ʻo ia ka mea maikaʻi loa no nā ʻōnaehana ikehu lā, nā RV, nā kaʻa kolepa, nā moku bass, a me nā kaʻa uila.
★ʻO kekahi o nā mea maikaʻi nui o kēia mau pila ʻo ko lākou ola pōʻaiapuni.
Hiki i kēia mau pila ke lōʻihi ma mua o 4x ka lōʻihi ma mua o nā mea ʻē aʻe.ʻOi aku ka palekana a hiki i ka 100% hohonu o ka hoʻokuʻu ʻana, ʻo ia ka mea hiki ke hoʻohana ʻia no kahi manawa lōʻihi.
Aia ma lalo iho nā kumu hou aʻe i ʻoi aku ka maikaʻi o kēia mau ʻokoʻa i nā pākahi Li-ion.
★ Ke Kumukuai Haahaa
Hoʻokumu ʻia nā pākahi LFP me ka hao a me ka phosphorus.ʻO ke kumu kūʻai o nā pākaukau LFP i manaʻo ʻia e like me ka 70 pakeneka haʻahaʻa i kēlā me kēia kg ma mua o nā ʻona NMC waiwai nui.Hāʻawi ʻia kāna mea hoʻohui kemika i ka uku kumukūʻai.ʻO nā kumukūʻai kelepona haʻahaʻa haʻahaʻa i hōʻike ʻia no nā pā LFP i hāʻule ma lalo o $100/kWh no ka manawa mua ma 2020.
★Pili Kaiapuni liʻiliʻi
ʻAʻole i loaʻa i nā pihi LFP ka nickel a i ʻole kobalt, he kumukūʻai a nui ka hopena o ke kaiapuni.Hiki ke hoʻihoʻi ʻia kēia mau pākaukau e hōʻike ana i ko lākou eco-friendly.
★ Hoʻomaikaʻi i ka maikaʻi a me ka hana
Ua ʻike ʻia nā pākaukau LFP no ko lākou ola lōʻihi, e hoʻolilo iā lākou i koho kaulana no nā noi e koi ana i ka mana mana hilinaʻi a paʻa i ka manawa.ʻOi aku ka lohi o ka pohō o ka mana ma mua o nā pākahi lithium-ion ʻē aʻe, e kōkua ana i ka mālama ʻana i kā lākou hana no ka wā lōʻihi.Hoʻohui ʻia, loaʻa iā lākou ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ka hopena i ka liʻiliʻi o ke kūpaʻa kūloko a me ka wikiwiki o ka hoʻoiho / hoʻokuʻu ʻana.
★ Hoʻonui i ka palekana a me ka paʻa
Paʻa ka wela a me ka paʻa ʻana o nā pākahi LFP, no laila ʻaʻole hiki ke pahū a i ʻole ke ahi.Hoʻopuka ʻo LFP i hoʻokahi hapaono o ka wela o ka NMC waiwai nui i ka nickel.No ka mea, ʻoi aku ka ikaika o ka paʻa Co-O i nā pākahi LFP, ua hoʻokuʻu ʻia nā ʻātoma oxygen me ka mālie inā pōkole a wela paha.Eia kekahi, ʻaʻohe lithium i waiho ʻia i loko o nā cell i hoʻopiha piha ʻia, e hoʻohālikelike iā lākou i ka nalowale o ka oxygen i hoʻohālikelike ʻia i nā hopena exothermic i ʻike ʻia i nā cell lithium ʻē aʻe.
★ Liʻiliʻi a māmā
ʻOi aku ka māmā o nā Bateri LFP ma mua o 50% ma mua o nā pākaukau lithium manganese oxide.ʻOi aku ka māmā ma mua o 70% ma mua o nā pākaukau lead-acid.Ke hoʻohana ʻoe i kahi pākaukau LiFePO4 i loko o kahi kaʻa, hoʻohana ʻoe i ke kinoea liʻiliʻi a ʻoi aku ka nui o ka maneuverability.He liʻiliʻi a paʻa hoʻi lākou, e ʻae iā ʻoe e mālama i ka lewa ma kāu scooter, waʻa, RV, a i ʻole ka noi ʻoihana.
LiFePO4 Bateri vs. Non-Lithium Bateri
He nui nā pōmaikaʻi o nā pākahi lithium akā hiki ke hoʻololi ʻia i ka wā waena ma muli o ka hiki ke loaʻa i nā pā LiFePo4 hou no ka mea ʻoi aku ka maikaʻi o ka ʻenehana kahiko.
☆ Nā Baʻa Akika Lead
ʻIke ʻia paha he kumukūʻai maikaʻi nā pākaʻi lead-acid i ka wā mua, akā ʻoi aku ka nui o ke kumukūʻai i ka wā lōʻihi.ʻO kēia ma muli o ke koi ʻana o lākou i ka mālama pinepine ʻana a me ka hoʻololi.He 2-4 mau manawa lōʻihi ka LiFePO4 me ka mālama ʻole.
☆ Nā Baʻa Gel
ʻAʻole koi ʻia nā pila gel, e like me LiFePO4, i ka hoʻouka hou ʻana a ʻaʻole e nalowale ka uku i ka wā e mālama ʻia ai.Akā ʻoi aku ka lohi o nā pila gel.Pono lākou e hoʻopau koke i ka hoʻopiha piha ʻana e pale i ka luku.
☆ AGM nā ʻōhua
ʻOiai ʻoi aku ka nui o ka pōʻino ʻana o nā pākahi AGM ma lalo o 50% ka nui, hiki ke hoʻokuʻu ʻia nā ʻāpana LiFePO4 me ka ʻole o ka pōʻino.Eia kekahi, paʻakikī ke mālama iā lākou.
Nā noi no nā Bateri LiFePO4
He nui nā pono waiwai o nā pākaukau LiFePO4, me
● Nā Waʻa lawaiʻa a me nā Kaʻa: Hiki iā ʻoe ke hoʻonui i ka manawa ma ka wai me ka liʻiliʻi o ka manawa hoʻouka a me ka manawa holo lōʻihi.ʻO ke kaumaha liʻiliʻi e hāʻawi i ka maʻalahi o ka lawelawe ʻana a me ka wikiwiki wikiwiki i ka wā o nā hoʻokūkū lawaiʻa kiʻekiʻe.
● ʻO nā scooter a me nā moped: ʻAʻohe paona make e hoʻolohi iā ʻoe.E hoʻopaʻa i kāu pākaukau i ka liʻiliʻi ma mua o ka piha piha no nā huakaʻi hele wale me ka ʻole o ka pōʻino.
●Nā hoʻonohonoho ʻana o ka lā: E hali i nā ʻokoʻa liʻiliʻi LiFePO4 ma nā wahi a pau e lawe ai ke ola iā ʻoe (ʻoiai i ka mauna a i ʻole ma waho o ka pā) e hoʻohana i ka mana o ka lā.
●Ka hoʻohana pāʻoihana: ʻO kēia nā pahu lithium palekana a paʻakikī loa e kūpono iā lākou no nāʻoihanaʻoihana e like me nā mīkini papahele, liftgates, a me nā mea'ē aʻe.
Eia kekahi, hoʻohana nā pākahi lithium iron phosphate i nā mea hana ʻē aʻe e like me nā kukui uila, nā uila uila, nā mea lekiō, nā kukui pilikia, a me nā mea ʻē aʻe.
Hiki i ka hoʻokō ʻana i ka LFP Wid-Scale
ʻOiai ʻoi aku ka liʻiliʻi o nā pali LFP a ʻoi aku ka paʻa ma mua o nā mea ʻē aʻe, ua lilo ka nui o ka ikehu i mea pale nui i ka hoʻohana nui ʻana.He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa loa nā pākahi LFP, ma waena o 15 a me 25%.Eia nō naʻe, ke hoʻololi nei kēia me ka hoʻohana ʻana i nā electrodes mānoanoa e like me nā mea i hoʻohana ʻia i ka Model 3 i hana ʻia e Shanghai, nona ka ikehu o 359Wh/lita.
Ma muli o ka lōʻihi o ke ola ʻana o nā pākahi LFP, ʻoi aku ka nui o ko lākou mana ma mua o nā pā Li-ion o ke kaumaha like.ʻO ia ke ʻano o ka hoʻohālikelike ʻana o ka ikehu o kēia mau pākahi i ka manawa.
ʻO kahi pale ʻē aʻe i ka lawe ʻana i ka lehulehu ʻo ia ka mea i lanakila ai ʻo Kina i ka mākeke ma muli o ka pepehi ʻana i nā patent LFP.I ka pau ʻana o kēia mau patent, aia ka manaʻo e ʻike ʻia ka hana ʻana o LFP, e like me ka hana ʻana o nā kaʻa.
Hoʻohana nui nā kaʻa kaʻa nui e like me Ford, Volkswagen, a me Tesla i ka ʻenehana ma o ka hoʻololi ʻana i nā nickel a i ʻole cobalt formulations.ʻO ka hoʻolaha hou ʻana e Tesla i kāna hōʻano hou i kēlā me kēia hapaha ka hoʻomaka wale nō.Ua hāʻawi pū ʻo Tesla i kahi hōʻano pōkole ma kāna pākaukau 4680, e ʻoi aku ka nui o ka ikehu a me ka laulā.Hiki nō hoʻi iā Tesla ke hoʻohana i ka hana "cell-to-pack" e hoʻohui i nā cell hou aʻe a hoʻokipa i ka haʻahaʻa haʻahaʻa o ka ikehu.
ʻOiai kona mau makahiki,LFPa he mea koʻikoʻi paha ka hoʻemi ʻana i nā kumukūʻai pākaukau i ka wikiwiki ʻana i ka lawe ʻana i ka EV.Ma ka 2023, manaʻo ʻia nā kumukūʻai lithium-ion kokoke i $100/kWh.Hiki i nā LFP ke hiki i nā mea hana kaʻa ke hoʻoikaika i nā mea e like me ka maʻalahi a i ʻole ka manawa hoʻomaha ma mua o ke kumukūʻai.
