Iyo yakanaka electrode yelithium-ion mabhatiriiri lithium iron phosphate material, ine mabhenefiti makuru mukuchengetedza kuita uye kutenderera hupenyu.Aya ndiwo mamwe akanyanya kukosha tekinoroji zviratidzo zvesimba bhatiri.Lifepo4 bhatiri ine 1C yekuchaja uye yekuburitsa kutenderera hupenyu hunogona kuwanikwa 2000 nguva, iyo puncture haina kuputika, haisi nyore kupisa uye kuputika kana yakawandisa.Lithium iron phosphate cathode zvinhu zvinoita kuti hombe-inokwana lithium-ion mabhatiri nyore kushandisa munhevedzano.
Lithium iron phosphate se cathode zvinhu
Lifepo4 bhatiri inoreva lithium-ion bhatiri rinoshandisa lithium iron phosphate seyakanaka electrode zvinhu.Iyo yakanaka electrode zvinhu zve lithium-ion mabhatiri anonyanya kusanganisira lithium cobaltate, lithium manganate, lithium nicklate, ternary zvinhu, lithium iron phosphate, nezvimwe zvakadaro.Pakati pavo, lithium cobaltate ndiyo yakanaka electrode zvinhu zvinoshandiswa mumabhatiri akawanda e-lithium-ion.Mumusimboti, lithium iron phosphate zvakare iri embedding uye deintercalation process.Iyi nheyo yakafanana ne lithium cobaltate uye lithium manganate.
lifepo4 bhatiri zvakanakira
1. Kuchaja kwepamusoro uye kuburitsa kushanda zvakanaka
Lifepo4 bhatiri i lithium-ion yechipiri bhatiri.Chimwe chinangwa chikuru ndere mabhatiri emagetsi.Iyo ine mabhenefiti makuru pamusoro peNI-MH uye Ni-Cd mabhatiri.Lifepo4 bhatiri ine yakakwira chaji uye inoburitsa kunyatsoshanda, uye kuchaja uye kuburitsa kushanda zvakanaka kunogona kusvika pamusoro pe90% pasi pemamiriro ekubuda, nepo lead-asidhi bhatiri ingangoita 80%.
2. lifepo4 bhatiri yakakwirira kuchengetedza kuita
Iyo PO bond mu lithium iron phosphate crystal yakagadzikana uye yakaoma kuparara, uye haiputsi kana kupisa se lithium cobaltate kana kuumba chinhu chakasimba oxidizing kunyange pakupisa kwepamusoro kana kudarika, uye nokudaro ine kuchengeteka kwakanaka.mukushanda chaiko. , chikamu chiduku chemuenzaniso chakawanikwa chine chiitiko chinopisa mu acupuncture kana pfupi-circuit test, asi pakanga pasina chiitiko chekuputika.Muchiyedzo che overcharge, chaji ye-high-voltage yaive yakakwira kakawanda pane yekuzvibvisa yega yakashandiswa, uye zvakaonekwa kuti pakanga pachine chiitiko cheKuputika.Zvakangodaro, kuchengetedzeka kwayo kwekuwedzeredza kwakavandudzwa zvakanyanya zvichienzaniswa neyakajairwa mvura electrolyte lithium cobalt oxide bhatiri.
3. Lifepo4 bhatiri hupenyu hurefu hwekutenderera
Lifepo4 bhatiri inoreva lithium-ion bhatiri rinoshandisa lithium iron phosphate seyakanaka electrode zvinhu.Iyo yehurefu-yehupenyu inotungamira-asidhi bhatiri ine kutenderera hupenyu hwenguva dzinosvika mazana matatu, uye iyo yepamusoro ndeye 500 nguva.Iyo lithium iron phosphate simba bhatiri ine hupenyu hwekutenderera kweanopfuura 2000 nguva, uye chiyero chechaji (5-awa chiyero) inogona kushandiswa kusvika ku2000 nguva.Iyo yakafanana mhando lead-asidi bhatiri "itsva hafu yegore, yekare hafu yegore, kuchengetedza uye kuchengetedza kwehafu yegore", kusvika ku1 ~ 1.5 makore, uye lifepo4 bhatiri rinoshandiswa pasi pemamiriro akafanana, hupenyu hwekufungidzira huchaita. kusvika 7-8 makore.Tichifunga zvizere, muyero wemutengo wekuita unodarika zvakapetwa kana zvemabhatiri e-lead-acid.Kubuda kwepamusoro-ikozvino kunogona kubhadhariswa nekukurumidza uye kuburitswa neiyo yakakwira ikozvino 2C.Pasi pejaja yakakosha, bhatiri rinogona kuzara mukati me1.5 maminetsi e1.5C kuchaja, uye yekutanga ikozvino inogona kusvika 2C, asi lead-asidhi bhatiri haina kuita kwakadaro.
4. Kuita kwakanaka kwekushisa
Iyo tembiricha yepamusoro yelithium iron phosphate inogona kusvika 350 ° C -500 ° C nepo lithium manganate uye lithium cobaltate inongotenderedza 200 ° C. Wide yekushanda tembiricha range (-20C–+75C), ine yakakwirira-tembiricha kuramba, lithium iron phosphate. electric heat peak inogona kusvika 350 °C-500 °C, ukuwo lithium manganate uye lithium cobalt oxide chete pa200 °C.
5. Lifepo4 bhatiri High capacity
Iine simba rakakura kudarika mabhatiri akajairwa (lead-acid, nezvimwewo).Iyo monomer inokwana 5AH-1000AH.
6. Hapana ndangariro mhedzisiro
Rechargeable mabhatiri anoshanda pasi pemamiriro ayo kazhinji asina kuburitswa zvizere, uye huwandu huchakurumidza kuwira pasi peyakayerwa huwandu.Chiitiko ichi chinonzi memory effect.Memory yakafanana nickel-metal hydride uye nickel-cadmium mabhatiri, asi lifepo4 bhatiri haina chiitiko ichi, pasinei nemamiriro ezvinhu bhatiri iri mukati, inogona kushandiswa nechaji, hapana chikonzero chekubudisa uye recharge.7.Huremu hwelifepo4 bhatiri
Iyo lifepo4 bhatiri reiyo yakafanana dhizaini bhatiri i2/3 yevhoriyamu yelead-asidhi bhatiri, uye huremu i1/3 yebhatiri relead-acid.
8. Lifepo4 mabhatirivane ushamwari nemhoteredzo
Bhatiri rinowanzoonekwa sekusina chero simbi inorema uye isingawanzo simbi (Ni-MH mabhatiri anoda isingawanzo simbi), isina-chepfu (SGS yakasimbiswa), isingasvibise, inoenderana neEuropean RoHS mirau, ndeye yakaperera girinhi bhatiri chitupa. .Naizvozvo, chikonzero nei mabhatiri e-lithium achifarirwa neindasitiri inonyanya kufunga nezvezvakatipoteredza.Nokudaro, bhatiri rakabatanidzwa mu "863" yenyika yepamusoro-soro chirongwa chekusimudzira munguva ye "Gumi-Makore mashanu Chirongwa" uye yave yenyika yakakosha kutsigira nekukurudzira chirongwa chekusimudzira.Nekupinda kweChina kuWTO, huwandu hwekutengesa kunze kwemabhasikoro emagetsi kuChina huchawedzera nekukurumidza, uye mabhasikoro emagetsi achipinda muEurope neUnited States ave kudiwa kuti ange aine mabhatiri asingasvibise.Kuita kwebhatiri ye lithium-ion kunoenderana zvakanyanya nezvakanaka uye zvisina kunaka zvinhu.Lithium iron phosphate ndeye lithium bhatiri zvinhu izvo zvakangoonekwa mumakore achangopfuura.Kuchengetedza kwayo kuita uye hupenyu hwekutenderera hazvienzaniswi nezvimwe zvinhu.Izvo zvakakosha zvehunyanzvi zviratidzo zvebhatiri.Lifepo4 bhatiri ine zvakanakira kwete-chepfu, isina-kusvibisa, yakanaka kuchengetedzwa kwekuita, huwandu hwakawanda hwezvigadzirwa, mitengo yakaderera, uye hupenyu hurefu.Iyo yakanaka cathode zvinhu zvechizvarwa chitsva chelithium-ion mabhatiri.
