Chii chinonzi Lithium Iron Phosphate?

Icho chinowanzo fungira kuti lithium iron phosphate mabhatiri akasiyana ne lithium-ion mabhatiri.Muchokwadi, kune akawanda marudzi emabhatiri e-lithium-ion, uye lithium iron phosphate inongova imwe yadzo.

Ngatitarisei kuti chii chaizvo chinonzi lithium iron phosphate, nei iri sarudzo yakanaka kune mamwe marudzi emabhatiri, uye kuti inofananidzwa sei nedzimwe sarudzo dze lithium-ion bhatiri.

Chii chinonzi Lithium Iron Phosphate?

Lithium iron phosphate ikemikari inosanganiswa LiFePO4 kana "LFP" kwenguva pfupi.LFP inopa yakanaka electrochemical performance, yakaderera kuramba uye ndeimwe yakachengeteka uye yakagadzikana zvakanyanya cathode zvinhu zviripo kune lithium-ion mabhatiri.

Chii chinonzi Lithium Iron Phosphate Battery?

Lithium iron phosphate mabhatiri imhando ye lithium-ion bhatiri inoshandisa lithium iron phosphate se cathode material kuchengeta lithium ions.LFP mabhatiri anowanzo shandisa graphite seanode zvinhu.Iko kemikari yekugadzira mabhatiri eLFP inovapa yakakwira ikozvino chiyero, yakanaka kugadzikana kwemafuta, uye hupenyu hurefu.

Mazhinji lithium iron phosphate mabhatiri ane mana mabhatiri maseru akaiswa munhevedzano.Iyo yezita remagetsi yeLFP bhatiri cell ndeye 3.2 volts.Kubatanidza masero mana ebhatiri reLFP munhevedzano kunoguma nebhatiri re12-volt iri yakanakisa kutsiva sarudzo kune akawanda 12-volt lead-asidhi mabhatiri.

Lithium Iron Phosphate Vs.Alternative Lithium-Ion Mhando

Lithium iron phosphate ingori imwe yemhando dzakawanda dzemabhatiri e-lithium-ion.Kushandura kemikari yekemikari ye cathode inogadzira marudzi akasiyana emabhatiri e-lithium-ion.Dzimwe dzesarudzo dzinowanzozivikanwa ndeiyi Lithium Cobalt Oxide (LCO), Lithium Manganese Oxide (LMO), Lithium Nickel Cobalt Aluminium Oxide (NCA), Lithium Nickel Manganese Cobalt Oxide (NMC), uye Lithium Titanate (LTO).

Imwe neimwe yemhando dzebhatiri idzi dzine masimba akasiyana uye kushaya simba izvo zvinovaita kuti vakwane kune akasiyana maapplication.Tichitarisa zvinhu zvikuru zveaya mabhatiri marudzi, tinogona kuona pamire lithium iron phosphate mabhatiri uye kuti ndeapi maapplication aakanyanya kunaka.

Energy Density

Mabhatiri eLFP ane imwe yemhando yepamusoro-soro yemagetsi pakati pemamwe marudzi e-lithium-ion.Mune mamwe mazwi, yakakwirira chaiyo simba zvinoreva kuti LFP mabhatiri anogona kuendesa yakakwira huwandu hwazvino uye simba pasina kupisa.

Nekune rimwe divi, zvakakosha kuti tirambe tichifunga kuti mabhatiri eLFP ane imwe yeakadzika yakananga simba ratings.Simba rakaderera rinoreva kuti mabhatiri eLFP ane mashoma ekuchengetedza simba pahuremu pane mamwe ma lithium-ion sarudzo.Ichi hachisati chiri chinhu chikuru nekuti kuwedzera bhatiri bhangi kugona kunogona kuitwa nekubatanidza akawanda mabhatiri akafanana.Izvi zvinogona kunge zvisiri zvakanakira application panodiwa kusimba kwesimba rakanyanyisa munzvimbo yakareruka, senge mota dzemagetsi ebhatiri.

Battery Life Cycles

Mabhatiri eLithium iron phosphate ane hupenyu hunotanga paanenge zviuru zviviri zvakazara ekuburitsa uye anowedzera zvichienderana nekudzika kwekubuda.Masero uye yemukati mebhatiri manejimendi system (BMS) anoshandiswa paDragonfly Energy akaedzwa kusvika pamusoro pe5,000 akazara ekuburitsa madhijitari achichengeta 80% yehuwandu hwebhatiri rekutanga.

LFP ndeyechipiri chete kune lithium titanate muhupenyu.Nekudaro, mabhatiri eLTO anga agara ari anonyanya kudhura lithium-ion bhatiri sarudzo, zvichiita kuti aite mari-inorambidza kune akawanda maapplication.

Discharge Rate

Chiyero chekubuda chinoyerwa muhuwandu hwehuwandu hwebhatiri, zvichireva kuti chiyero chekubuda che1C chebhatiri re100Ah 100A inoenderera.Mabhatiri eLFP anowanikwa mune zvekutengesa ane 1C inoenderera yekuburitsa chiyero asi anogona kudarika izvi kwenguva pfupi zvichienderana nebhatiri manejimendi system.

Masero eLFP pachawo anogona kupa 25C kubuda kwenguva pfupi zvakachengeteka.Iko kugona kudarika 1C inobvumidza iwe kushandisa mabhatiri eLFP mune yakakwirira-simba maapplication anogona kunge aine mapikisi ekutanga mudhirowa iripo.

Operating Temperatures

Mabhatiri eLFP haapinde mumamiriro ekupisa kusvika kusvika 270 degrees Celsius.Kuenzaniswa nedzimwewo zvakajairika lithium-ion bhatiri sarudzo, LFP mabhatiri ane yechipiri-yepamusoro yekushanda tembiricha muganho.

Kupfuura muganho wekushisa pane lithium-ion bhatiri kunokonzera kukanganisa uye kunogona kutungamirirathermal runaway, zvichida kuguma nemoto.Iyo yakakwirira yekushanda muganho weLFP inoderedza zvakanyanya mukana wechiitiko chinopisa chinotiza.Yakasanganiswa neBMS yemhando yepamusoro yekuvharisa maseru pamberi pemamiriro aya (pakutenderera 57 degrees Celsius), LFP inopa zvakakosha kuchengetedza zvakanakira.

Kuchengetedzwa Kwakanakira

LFP mabhatiri ndeimwe yemakemistri akagadzikana ezvese eti lithium-ion sarudzo.Uku kugadzikana kunoita kuti ive imwe yedzakachengeteka sarudzo kune ese ari maviri akatarisana nevatengi uye maindasitiri maapplication.

Imwe chete yakachengeteka sarudzo ndeye lithium titanate, iyo zvakare inowanzo kudhura-inorambidza uye haishande pamhepo chaiyo mune dzakawanda mamiriro ekutsiva 12V.

Lithium Iron Phosphate Vs.Lead-Acid Mabhatiri

Lithium iron phosphate mabhatiri anopa akawandazvakanakira pamusoro pechinyakare lead-asidhi mabhatiri.Chinonyanya kucherechedzwa ndechekuti mabhatiri eLFP ane kanokwana kana kuwanda kwesimba remabhatiri e-lead-acid.Iwe unogona kudzika-kutenderera mabhatiri eLFP kakawanda pasina kuvakuvadza.Ivo zvakare vanochaja 5 nekukurumidza kupfuura lead-asidhi mabhatiri.

Uku kusimba kwesimba kwakanyanya kunotungamira kune imwe nguva yekumhanya panguva imwe chete ichidzikisa huremu hwebhatiri system.

Kuitwa kwekemikari mukati memabhatiri e-lead-asidhi kunokonzera off-gassing, izvo zvinoda kuti mabhatiri apinzwe mhepo uye nguva nenguva achizadzwa nemvura nemushandisi.Kana mabhatiri asina kuchengetwa akatwasuka, asidhi mhinduro inogona kudonha, ichikuvadza bhatiri uye kukonzera nyonga nyonga.Neimwe nzira, mabhatiri eLFP haabvi-gasi uye haadi kuburitswa kana kuzadzwazve.Kunyangwe zvirinani, iwe unogona kuzviisa mune chero maitiro.

Mabhatiri eLFP pakutanga anodhura kupfuura mabhatiri e-lead-acid.Nekudaro, hupenyu hurefu hwemabhatiri eLFP hunoyeresa mutengo wavo wepamusoro wepamberi.Muzviitiko zvakawanda, mabhatiri eLFP achagara 5-10 nguva yakareba kupfuura lead-asidhi mabhatiri, zvichikonzera kukosha kwese kuchengetwa kwemutengo.

Akanakisa Lithium Iron Phosphate Mabhatiri Ekutsiva Lead-Asidhi Bhatiri Maapplication

Mabhatiri akawanda e-lithium-ion akasiyana aripo, uye mamwe anotopfuura lithium iron phosphate mune mamwe maitiro ekuita.Zvisinei, kana zvasvika pakutsiva 12-volt lead-acid mabhatiri, LFP ndiyo yakanakisa sarudzo iripo.

Chikonzero chikuru cheizvi ndechekuti zita remagetsi sero re lithium iron phosphate i3.2 volts.Iyo yezita remagetsi ye12-volt lead-asidhi bhatiri inosvika 12.7 volts.Nokudaro, wiring masero mana mumutsara mukati mebheteri inobereka 12.8 volts (4 x 3.2 = 12.8) - inenge yakafanana yakakwana!Izvi hazvigoneke neimwe imwe lithium-ion bhatiri mhando.

Pamusoro peinoda kukwana voltage match, LFP inopa mamwe mabhenefiti sekutsiva-asidhi yekutsiva.Sezvakakurukurwa pamusoro apa, mabhatiri eLFP anogara kwenguva refu, akagadzikana, akachengeteka, akasimba, asingaremi, uye ane simba guru.Izvi zvinoita kuti ive yakanyatsokodzera kune akawanda maapplication!Zvinhu zvakadaitrolling motors,RVs,ngoro dzegorofu, uye mamwe maapplication agara achivimba nemabhatiri e-lead-asidhi.

Dragonfly Energy uye Hondo Yakazvarwa Mabhatiri anovaka mamwe emhando yepamusoro lithium iron phosphate mabhatiri aripo.Iwo akagadzirwa anodada uye akaunganidzwa muUnited States aine emhando yepamusoro zvinhu zviripo.Pamusoro pezvo, bhatiri rega rega rinoyedzwa zvine simba uye UL yakanyorwa.

Bhatiri rimwe nerimwe rinosanganisirawo rakasanganiswabhatiri manejimendi systemkuve nechokwadi chekuti bhatiri rinoshanda zvakachengeteka pasi pemamiriro ese.Dragonfly Energy uye Hondo Yakazvarwa Mabhatiri ane zviuru zvemabhatiri akaiswa uye anoshanda zvakachengeteka mune akawanda akasiyana maapplication pasi rese.

Zvino Iwe Unoziva

Mukupedzisa, lithium iron phosphate ingori imwe yemhando dzakasiyana dzemabhatiri e-lithium-ion aripo.Nekudaro, iyo yakasarudzika seti yehunhu inoumba mabhatiri eLFP inovaita imwe nzira inoshamisa kune 12-volt lead-asidhi mabhatiri ekare.
