Ndizolakwika zodziwika kuti mabatire a lithiamu iron phosphate ndi osiyana ndi mabatire a lithiamu-ion.Kunena zoona, pali mitundu yambiri ya mabatire a lithiamu-ion, ndipo lithiamu iron phosphate ndi imodzi mwa izo.
Tiyeni tiwone chomwe lifiyamu chitsulo phosphate ndi chiyani, chifukwa chake ndi chisankho chabwino pamitundu ina ya mabatire, komanso momwe ikufananizira ndi zosankha zina za batri ya lithiamu-ion.
Kodi Lithium Iron Phosphate ndi chiyani?
Lithium iron phosphate ndi mankhwala omwe ali ndi LiFePO4 kapena "LFP" mwachidule.LFP imapereka magwiridwe antchito abwino a electrochemical, kukana otsika ndipo ndi imodzi mwazinthu zotetezeka komanso zokhazikika za cathode zomwe zimapezeka pamabatire a lithiamu-ion.
Kodi Battery ya Lithium Iron Phosphate ndi chiyani?
Mabatire a lithiamu iron phosphate ndi mtundu wa batri ya lithiamu-ion yomwe imagwiritsa ntchito lithiamu iron phosphate ngati zinthu za cathode kusunga ma ion a lithiamu.Mabatire a LFP nthawi zambiri amagwiritsa ntchito graphite ngati zinthu za anode.Mapangidwe amankhwala a mabatire a LFP amawapangitsa kukhala okwera kwambiri, kukhazikika kwamafuta abwino, komanso moyo wautali.
Mabatire ambiri a lithiamu iron phosphate ali ndi ma cell anayi a batire omwe amalumikizidwa motsatizana.Mphamvu yamagetsi ya cell ya batri ya LFP ndi 3.2 volts.Kulumikiza ma cell anayi a batri a LFP pamndandanda kumabweretsa batire ya 12-volt yomwe ndi njira yabwino kwambiri yosinthira mabatire ambiri a 12-volt lead-acid.
Lithium Iron Phosphate vs.Mitundu ina ya Lithium-Ion
Lithium iron phosphate ndi imodzi mwa mitundu yambiri ya mabatire a lithiamu-ion.Kusintha mankhwala a cathode kumapanga mitundu yosiyanasiyana ya mabatire a lithiamu-ion.Zina mwazodziwika bwino ndi Lithium Cobalt Oxide (LCO), Lithium Manganese Oxide (LMO), Lithium Nickel Cobalt Aluminium Oxide (NCA), Lithium Nickel Manganese Cobalt Oxide (NMC), ndi Lithium Titanate (LTO).
Iliyonse mwa mitundu ya batri iyi ili ndi mphamvu ndi zofooka zosiyanasiyana zomwe zimawapangitsa kukhala oyenera pamapulogalamu osiyanasiyana.Kuyang'ana zinthu zazikulu zamitundu ya batri iyi, titha kuwona komwe mabatire a lithiamu iron phosphate amaima komanso kuti ndi mapulogalamu ati omwe ali abwino kwambiri.
Kuchuluka kwa Mphamvu
Mabatire a LFP ali ndi amodzi mwamagawo apamwamba kwambiri amphamvu pakati pa mitundu ina ya lithiamu-ion.Mwa kuyankhula kwina, mphamvu yeniyeni yeniyeni imatanthauza kuti mabatire a LFP amatha kutulutsa mphamvu zambiri zamakono ndi mphamvu popanda kutenthedwa.
Kumbali inayi, ndikofunikira kukumbukira kuti mabatire a LFP ali ndi amodzi mwamagawo otsika kwambiri amphamvu.Mphamvu zochepa zomwe zimatanthawuza kuti mabatire a LFP ali ndi mphamvu zochepa zosungira mphamvu pa kulemera kwake kusiyana ndi njira zina za lithiamu-ion.Izi nthawi zambiri sizovuta chifukwa kukulitsa mphamvu ya banki ya batri kumatha kuchitika polumikiza mabatire angapo molumikizana.Izi sizingakhale zabwino kugwiritsa ntchito komwe kumafunikira mphamvu zochulukirapo pamalo opepuka kwambiri, monga magalimoto amagetsi a batri.
Battery Life Cycles
Mabatire a Lithium iron phosphate amakhala ndi moyo wautali womwe umayamba pafupifupi 2,000 kutulutsa kwathunthu ndikuwonjezeka kutengera kuya kwa kukhetsa.Maselo ndi makina oyendetsera batire amkati (BMS) omwe amagwiritsidwa ntchito ku Dragonfly Energy ayesedwa mpaka kupitilira 5,000 kutulutsa kwathunthu kwinaku akusunga 80% ya mphamvu ya batire yoyambirira.
LFP ndi yachiwiri kwa lithiamu titanate m'moyo wonse.Komabe, mabatire a LTO akhala akukhala okwera mtengo kwambiri a lithiamu-ion batire, kuwapangitsa kukhala otsika mtengo pamapulogalamu ambiri.
Mtengo Wotulutsa
Kuthamanga kwa batire kumayesedwa mu kuchuluka kwa kuchuluka kwa batire, kutanthauza kuti 1C yotulutsa batire ya 100Ah ndi 100A mosalekeza.Mabatire a LFP omwe amapezeka pamalonda nthawi zambiri amakhala ndi 1C yotulutsa mosalekeza koma amatha kupitilira izi kwakanthawi kochepa kutengera dongosolo la kasamalidwe ka batri.
Maselo a LFP eni ake amatha kutulutsa kutulutsa kwa 25C kwakanthawi kochepa.Kutha kupitilira 1C kumakupatsani mwayi wogwiritsa ntchito mabatire a LFP pamapulogalamu amphamvu kwambiri omwe atha kukhala ndi zoyambira pakujambula komweko.
Kutentha kwa Ntchito
Mabatire a LFP salowa m'malo othawirako kutentha mpaka pafupifupi madigiri 270 Celsius.Poyerekeza ndi njira zina zodziwika bwino za batri ya lithiamu-ion, mabatire a LFP ali ndi kutentha kwachiwiri kwapamwamba kwambiri.
Kupitirira malire a kutentha kwa batri ya lithiamu-ion kumayambitsa kuwonongeka ndipo kungayambitsekutentha kwathawa, mwina kuchititsa moto.Kutsika kwakukulu kwa LFP kumachepetsa kwambiri mwayi wa chochitika chothawa kutentha.Kuphatikizidwa ndi BMS yapamwamba kwambiri kuti atseke ma cell bwino izi zisanachitike (pafupifupi madigiri 57 Celsius), LFP imapereka zabwino zambiri zachitetezo.
Ubwino Wachitetezo
Mabatire a LFP ndi amodzi mwamafakitale okhazikika pazosankha zonse za lithiamu-ion.Kukhazikika uku kumawapangitsa kukhala amodzi mwa njira zotetezeka kwambiri pazogwiritsa ntchito zomwe zimayang'ana ogula komanso mafakitale.
Njira ina yokhayo yotetezeka ndi lithiamu titanate, yomwe nthawi zambiri imakhala yotsika mtengo ndipo siigwira ntchito pamagetsi olondola nthawi zambiri m'malo mwa 12V.
Lithium Iron Phosphate vs.Mabatire a Lead-Acid
Mabatire a lithiamu iron phosphate amapereka zambiriubwino kuposa mabatire amtundu wa lead-acid.Chodziwika kwambiri ndi chakuti mabatire a LFP ali ndi mphamvu pafupifupi kanayi kuchulukitsa kwamphamvu kwa mabatire a lead-acid.Mutha kuzungulira mabatire a LFP mobwerezabwereza osawawononga.Amawonjezeranso 5 mwachangu kuposa mabatire a lead-acid.
Kuchulukana kwamphamvu kumeneku kumabweretsa nthawi yayitali yothamanga pomwe nthawi imodzi kumachepetsa kulemera kwa batire.
Zomwe zimachitika m'kati mwa mabatire a lead-acid zimapangitsa kuti mabatire azitulutsa mpweya, zomwe zimafuna kuti mabatire atulutsidwe ndi kuwonjezeredwa madzi nthawi ndi nthawi ndi wogwiritsa ntchito.Ngati mabatire sanasungidwe molunjika, asidi amatha kutuluka, kuwononga batire ndikuyambitsa chisokonezo.Kapenanso, mabatire a LFP samachoka pa gasi ndipo safunika kutulutsa mpweya kapena kudzazidwanso.Ngakhalenso bwino, mutha kuwayika mumayendedwe aliwonse.
Mabatire a LFP poyamba amakhala okwera mtengo kuposa mabatire a lead-acid.Komabe, kutalika kwa moyo wa mabatire a LFP kumawongolera mtengo wawo wapamwamba.Nthawi zambiri, mabatire a LFP amatenga nthawi yayitali 5-10 kuposa mabatire a asidi amtovu, zomwe zimapangitsa kuti pakhale ndalama zambiri.
Mabatire Abwino Kwambiri a Lithium Iron Phosphate Oti Asinthe Mabatire a Lead-Acid
Mabatire ambiri a lithiamu-ion alipo, ndipo ena amaposa phosphate ya lithiamu m'magulu ena ogwira ntchito.Komabe, zikafika posintha mabatire a 12-volt lead-acid, LFP ndiye njira yabwino kwambiri yomwe ilipo.
Chifukwa chachikulu cha izi ndikuti mphamvu yamagetsi yotchedwa lithiamu iron phosphate ndi 3.2 volts.Mphamvu yamagetsi ya batri ya 12-volt lead-acid ndi pafupifupi 12.7 volts.Chifukwa chake, ma waya anayi otsatizana mkati mwa batire amatulutsa 12.8 volts (4 x 3.2 = 12.8) - pafupifupi machesi abwino!Izi sizingatheke ndi mtundu wina wa batri wa lithiamu-ion.
Kupitilira machesi owoneka bwino amagetsi, LFP imaperekanso maubwino ena ngati m'malo mwa acid-acid.Monga tafotokozera pamwambapa, mabatire a LFP ndi okhalitsa, okhazikika, otetezeka, okhazikika, opepuka, komanso amakhala ndi mphamvu zambiri.Izi zimawapangitsa kukhala oyenera pamapulogalamu ambiri!Zinthu ngatima trolling motors,RVs,ngolo za gofu, ndi ntchito zambiri zomwe mwamwambo zimadalira mabatire a lead-acid.
Dragonfly Energy ndi Battle Born Battery amapanga mabatire abwino kwambiri a lithiamu iron phosphate omwe alipo.Amapangidwa monyadira ndikusonkhanitsidwa ku United States ndi zida zapamwamba kwambiri zomwe zilipo.Kuphatikiza apo, batire iliyonse imayesedwa mwamphamvu ndipo UL yalembedwa.
Batire iliyonse imaphatikizansopo chophatikizikakasamalidwe ka batrikuonetsetsa kuti batire ikugwira ntchito mosatekeseka muzochitika zonse.Dragonfly Energy ndi Battle Born Batteries ali ndi mabatire masauzande ambiri omwe adayikidwa ndikugwira ntchito mosatekeseka pamapulogalamu osiyanasiyana padziko lonse lapansi.
Tsopano Inu mukudziwa
Pomaliza, lithiamu iron phosphate ndi imodzi mwa mitundu yosiyanasiyana ya mabatire a lithiamu-ion omwe alipo.Komabe, mawonekedwe apadera omwe amapanga mabatire a LFP amawapangitsa kukhala njira yabwino kwambiri kuposa mabatire a 12-volt lead-acid akale.
