He aha ka Lithium Iron Phosphate?

He manaʻo kuhihewa maʻamau ia he ʻokoʻa nā pā lithium iron phosphate ma mua o nā pā lithium-ion.ʻO ka ʻoiaʻiʻo, nui nā ʻano o nā pā lithium-ion, a ʻo ka lithium iron phosphate kekahi o lākou.

E nānā kāua i ke ʻano o ka lithium iron phosphate, no ke aha he koho maikaʻi loa ia no kekahi mau ʻano ʻano pila, a pehea ia e hoʻohālikelike ai i nā koho pākaukau lithium-ion ʻē aʻe.

He aha ka Lithium Iron Phosphate?

ʻO ka Lithium iron phosphate he pūhui kemika LiFePO4 a i ʻole "LFP" no ka pōkole.Hāʻawi ʻo LFP i ka hana electrochemical maikaʻi, haʻahaʻa haʻahaʻa a ʻo ia kekahi o nā mea cathode palekana a paʻa loa i loaʻa no nā pā lithium-ion.

He aha ka Lithium Iron Phosphate Battery?

ʻO nā ʻeke hao hao phosphate he ʻano pākaukau lithium-ion e hoʻohana ana i ka lithium iron phosphate ma ke ʻano he cathode e mālama ai i nā ion lithium.Hoʻohana maʻamau nā pākaukau LFP i ka graphite e like me ka mea anode.Hāʻawi ka hana kemika o nā pākahi LFP iā lākou i ka helu kiʻekiʻe o kēia manawa, ke kūpaʻa wela maikaʻi, a me ke ola lōʻihi.

ʻO ka hapa nui o nā pākahi lithium hao phosphate he ʻehā mau pūnaewele i hoʻopaʻa ʻia i ka moʻo.ʻO 3.2 volts ka volta helu o kahi pūnae uila LFP.ʻO ka hoʻohui ʻana i ʻehā mau pūnaewele pākahi LFP i ka moʻo e loaʻa i kahi pākaukau 12-volt he koho hoʻololi maikaʻi loa ia no nā ʻāpana 12-volt lead-acid he nui.

Lithium Iron Phosphate Vs.Nā ʻano Lithium-Ion ʻē aʻe

ʻO ka Lithium iron phosphate kekahi o nā ʻano pākahi lithium-ion.ʻO ka hoʻololi ʻana i ka pūhui kemika no ka cathode e hana i nā ʻano ʻokoʻa o nā ʻāpana lithium-ion.ʻO kekahi o nā koho maʻamau ʻo Lithium Cobalt Oxide (LCO), Lithium Manganese Oxide (LMO), Lithium Nickel Cobalt Aluminum Oxide (NCA), Lithium Nickel Manganese Cobalt Oxide (NMC), a me Lithium Titanate (LTO).

He ʻokoʻa nā ikaika a me nā nāwaliwali o kēlā me kēia ʻano pākaukau i kūpono iā lākou no nā noi like ʻole.Ke nānā nei i nā waiwai nui o kēia mau ʻano pākaukau, hiki iā mākou ke ʻike i kahi e kū ai nā pā lithium iron phosphate a no nā noi ʻoi aku ka maikaʻi.

ʻAiʻi ikaika

Loaʻa i nā pākahi LFP kekahi o nā helu mana kikoʻī kiʻekiʻe loa ma waena o nā ʻano lithium-ion ʻē aʻe.ʻO nā huaʻōlelo ʻē aʻe, ʻo ia ka mana kikoʻī kiʻekiʻe e hiki i nā ʻāpana LFP ke hāʻawi i ka nui o ka manawa a me ka mana me ka ʻole o ka wela.

Ma ka ʻaoʻao ʻē aʻe, he mea nui e hoʻomanaʻo e loaʻa i nā pākahi LFP kekahi o nā helu haʻahaʻa haʻahaʻa haʻahaʻa.ʻO ka ikehu haʻahaʻa haʻahaʻa, ʻo ia ka liʻiliʻi o ka hiki ke mālama ʻana i ka ikehu i nā ʻāpana LFP ma mua o nā koho lithium-ion ʻē aʻe.ʻAʻole kēia he hana nui no ka mea hiki ke hana ʻia ka hoʻonui ʻana i ka mana o ka waihona pākaukau ma o ka hoʻopili ʻana i nā pila he nui i ka like.ʻAʻole kūpono paha kēia no kahi noi kahi e koi ʻia ai ka nui o ka ikehu ma kahi māmā loa, e like me nā kaʻa uila.

Kaapuni Ola

Loaʻa ka lōʻihi o ke ola ʻana o nā pā hao hao phosphate e hoʻomaka ana ma kahi o 2,000 mau kaʻina hoʻokuʻu piha a hoʻonui ʻia ma muli o ka hohonu o ka hoʻokuʻu ʻana.Ua hoʻāʻo ʻia nā kelepona a me ka ʻōnaehana hoʻokele pākaukau i loko (BMS) i hoʻohana ʻia ma Dragonfly Energy ma luna o 5,000 mau kaʻina hoʻokuʻu piha ʻoiai e paʻa ana ka 80% o ka mana o ka pākaukau kumu.

ʻO ka LFP ka lua wale nō i ka lithium titanate i ke ola.Eia nō naʻe, ʻo nā pākahi LTO ka mea maʻamau i ke koho pākaukau lithium-ion nui loa, e hoʻolilo iā lākou i ke kumu kūʻai no ka hapa nui o nā noi.

Ka helu hoʻokuʻu

Ana ʻia ka nui o ka hoʻokuʻu ʻana i ka nui o ka mana o ka pākaukau, ʻo ia hoʻi, he 1C ka hoʻokuʻu ʻana no ka pā 100Ah he 100A mau.Loaʻa i nā pākaʻi LFP kūʻai kūʻai maʻamau i ka helu hoʻokuʻu mau ʻana he 1C akā hiki ke ʻoi aku i kēia no nā manawa pōkole ma muli o ka ʻōnaehana hoʻokele pākaukau.

Hiki i nā pūnaewele LFP ke hāʻawi i kahi hoʻokuʻu 25C no nā manawa pōkole me ka palekana.ʻO ka hiki ke ʻoi aku ma mua o 1C e hiki iā ʻoe ke hoʻohana i nā pākaukau LFP i nā noi mana kiʻekiʻe e loaʻa paha nā spike hoʻomaka i ka huki o kēia manawa.

Nā Mahana Hana

ʻAʻole komo nā ʻōhua LFP i nā kūlana holo wela a hiki i ka 270 degere Celsius.Ke hoʻohālikelike ʻia i nā koho pākaukau lithium-ion maʻamau, loaʻa i nā pākahi LFP ka lua o ka palena wela hana kiʻekiʻe loa.

ʻO ka ʻoi aku o ka palena wela ma ka pā lithium-ion ke kumu o ka pōʻino a hiki ke alakaʻi imahuka wela, malia paha he ahi.ʻO ka palena hana kiʻekiʻe o LFP e hoʻemi nui i ka manawa o kahi hanana holo wela.Hoʻohui ʻia me kahi BMS kiʻekiʻe e pani pono i nā cell ma mua o kēia mau kūlana (ma kahi o 57 degere Celsius), hāʻawi ʻo LFP i nā pono palekana koʻikoʻi.

Nā Pōmaikaʻi Palekana

ʻO nā pākahi LFP kekahi o nā kemika paʻa o nā koho lithium-ion āpau.ʻO kēia kūpaʻa e hoʻolilo iā lākou i kekahi o nā koho palekana no nā mea kūʻai aku a me nā noi ʻoihana.

ʻO kahi koho palekana ʻē aʻe ʻē aʻe he lithium titanate, ʻo ia ka mea maʻamau i ke kumu kūʻai ʻole a ʻaʻole hana ma ka volta kūpono i ka hapa nui o nā kūlana no kahi pani 12V.

Lithium Iron Phosphate Vs.Nā Bateri Lead-Acid

Hāʻawi ʻia nā pākaukau lithium iron phosphate i nā mea he nuiʻoi aku ka maikaʻi ma mua o nā pākaukau lead-acid.ʻO ka mea kaulana loa ʻo ia ka loaʻa ʻana o nā pākahi LFP ma kahi o ʻehā mau manawa o ka nui o ka ikehu o nā pākī lead-acid.Hiki iā ʻoe ke hoʻopololei i nā pākahi LFP hohonu me ka ʻole e hōʻino iā lākou.Hoʻopiha hou lākou i ka 5 wikiwiki ma mua o nā pākī lead-acid.

Ke alakaʻi nei kēia kiʻekiʻe ikehu kiʻekiʻe i kahi manawa holo lōʻihi me ka hoʻohaʻahaʻa like ʻana i ke kaumaha o ka ʻōnaehana pākahi.

ʻO ka hopena kemika i loko o nā pākaʻi lead-acid ka mea e hoʻopau ʻia ai ke kinoea, kahi e pono ai e hoʻokuʻu ʻia nā pila a hoʻopiha hou ʻia me ka wai e ka mea hoʻohana.Inā ʻaʻole mālama pono ʻia nā pākaukau, hiki ke kahe ka wai waika, e hōʻino i ka pākaukau a hoʻopilikia.ʻO kahi ʻē aʻe, ʻaʻole pau nā pila LFP a ʻaʻole pono e hoʻokuʻu ʻia a hoʻopiha hou ʻia.ʻOi aku ka maikaʻi, hiki iā ʻoe ke kau iā lākou i kēlā me kēia orientation.

ʻOi aku ke kumu kūʻai o nā pākahi LFP ma mua o nā pākī lead-acid.Eia nō naʻe, ʻo ka lōʻihi o ke ola ʻana o nā pākahi LFP e kaulike ana i ko lākou kumukūʻai kiʻekiʻe.I ka hapanui o nā hihia, e lōʻihi ka lōʻihi o nā pākahi LFP ma mua o 5-10 mau manawa ma mua o nā pākī lead-acid, e hopena i ka nui o ka mālama kālā.

ʻO nā Bateri Lithium Iron Phosphate ʻoi aku ka maikaʻi no ka hoʻololi ʻana i nā noi pākaukau Lead-Acid

Nui nā ʻokoʻa lithium-ion i loaʻa, a ʻoi aku kekahi ma mua o ka lithium iron phosphate i kekahi mau ʻano hana.Eia nō naʻe, i ka wā e hoʻololi ai i nā pākahi 12-volt lead-acid, ʻo LFP ke koho maikaʻi loa i loaʻa.

ʻO ke kumu nui o kēia, ʻo ka volts cell nominal no ka lithium iron phosphate he 3.2 volts.He 12.7 volts ka volt nominal o ka 12-volt lead-acid battery.No laila, ʻo ka hoʻopaʻa ʻana i ʻehā mau pūnaewele i loko o ka pākaukau e loaʻa ai ka 12.8 volts (4 x 3.2 = 12.8) - kokoke i kahi pāʻani maikaʻi loa!ʻAʻole hiki kēia me nā ʻano pākahi lithium-ion ʻē aʻe.

Ma waho aʻe o kahi pāʻani voltage kokoke loa, hāʻawi ʻo LFP i nā pono ʻē aʻe ma ke ʻano he hoʻololi lead-acid.E like me ka mea i kūkākūkā ʻia ma luna nei, lōʻihi ka lōʻihi, kūpaʻa, palekana, paʻa, māmā, a me ka ikehu kiʻekiʻe.He mea kūpono kēia iā lākou no nā noi he nui!Nā mea liketrolling motors,Nā RV,nā kaʻa kolepa, a me nā noi ʻē aʻe i hilinaʻi maʻamau i nā ʻaniani lead-acid.

Hoʻokumu ʻo Dragonfly Energy a me Battle Born Batteries i kekahi o nā pākahi lithium hao phosphate maikaʻi loa i loaʻa.Hoʻolālā haʻaheo lākou a hui pū ʻia ma ʻAmelika Hui Pū ʻIa me nā mea kiʻekiʻe loa i loaʻa.Eia kekahi, ua hoʻāʻo ikaika ʻia kēlā me kēia pākaukau a helu ʻia ʻo UL.

Hoʻohui pū ʻia kēlā me kēia pākaukauʻōnaehana hoʻokele pākaukaue hōʻoia i ka holo pono ʻana o ka pākaukau ma lalo o nā kūlana āpau.ʻO Dragonfly Energy a me Battle Born Batteries he mau kaukani mau ʻaʻa i hoʻokomo ʻia a hana palekana i nā noi like ʻole a puni ka honua.

I kēia manawa ua ʻike ʻoe

I ka hopena, ʻo ka lithium iron phosphate kekahi o nā ʻano like ʻole o nā pākahi lithium-ion i loaʻa.Eia nō naʻe, ʻo nā ʻano hiʻohiʻona kūʻokoʻa i hana i nā pākaukau LFP e lilo lākou i mea koho maikaʻi loa i nā pākaona lead-acid 12-volt o ka wā i hala.
