Zvakanakira zve lithium iron phosphate mabhatiri
1. Kuvandudzwa kwekuita kwekuchengetedza
Iyo PO bond mu lithium iron phosphate crystal yakagadzikana uye yakaoma kuparara.Kunyangwe pakupisa kwakanyanya kana kuwandisa, haizopunzike uye kuburitsa kupisa se lithium cobalt oxide kana kuumba yakasimba oxidizing zvinhu, saka ine chengetedzo yakanaka.Chirevo chakaratidza kuti mukushanda chaiko, nhamba shoma yemasampuli yakawanikwa ichipfuta muacupuncture kana pfupi-circuit miedzo, asi pakanga pasina kuputika.kuputika chiitiko.Kunyangwe zvakadaro, kuchengetedza kwayo kuwandisa kwakavandudzwa zvakanyanya kana zvichienzaniswa neyakajairwa mvura electrolyte lithium cobalt oxide mabhatiri.
2. Kuvandudzwa kwehupenyu
Lithium iron phosphate bhatiri inoreva lithium ion bhatiri inoshandisa lithium iron phosphate seyakanaka electrode zvinhu.
Upenyu hwehupenyu hwehupenyu hurefu hwemabhatiri e-lead-acid inenge ka300, uye iyo yakawanda ndeye 500 nguva, asi hupenyu hwekutenderera kwe lithium iron phosphate power mabhatiri hunogona kusvika kudarika nguva dze2,000, uye chiyero chekuchaja (5-awa chiyero) kushandiswa kunogona kusvika 2,000 nguva.Iyo lead-asidi bhatiri yemhando imwechete "itsva hafu yegore, yekare hafu yegore, uye kuchengetedza uye kuchengetedza kwehafu yegore", inova 1 ~ 1.5 makore zvakanyanya, uye lithium iron phosphate bhatiri inoshandiswa pasi pemamiriro akafanana, Theoretical hupenyu huchasvika 7 ~ 8 makore.Kutarisisa kwakadzama, chiyero chekushanda-mutengo chinoti inopfuura kane kane iyo yemabhatiri e-lead-asidhi.Kubuda kwepamusoro-ikozvino kunogona kukurumidza kuchaja uye kuburitsa yakakwira-ikozvino 2C.Pasi pechaja yakakosha, bhatiri rinogona kuzara mukati me40 maminetsi e1.5C kuchaja, uye yekutanga ikozvino inogona kusvika 2C, asi lead-asidhi mabhatiri haana kuita uku.
3. Kushanda kwakanaka kwekushisa kwepamusoro
Iyo yemagetsi kupisa peak ye lithium iron phosphate inogona kusvika 350 ℃-500 ℃, nepo lithium manganate uye lithium cobaltate inongotenderedza 200 ℃.Yakakura yekushanda tembiricha renji (-20C-75C), ine yakanyanya kupisa tembiricha, iyo yemagetsi kupisa peak yelithium iron phosphate inogona kusvika 350 ℃-500 ℃, nepo lithium manganate uye lithium cobaltate inongotenderedza 200 ℃.
4. Kugona kukuru
Mabhatiri anowanzo shanda pasi pemamiriro ekuchajiwa zvizere, uye simba rinokurumidza kudonha pasi peyero yakayerwa.Chiitiko ichi chinonzi memory effect.Kufanana nickel-metal hydride uye nickel-cadmium mabhatiri, pane chiyeuchidzo, asi lithium iron phosphate mabhatiri haana chiitiko ichi.Hazvina mhosva kuti bhatiri riri mumamiriro akaita sei, rinogona kushandiswa chero nguva pasina kuribvisa risati rachaja.
5. Kurema kwakareruka
Vhoriyamu yebhatiri yelithium iron phosphate ine chirevo chakafanana uye kugona ndeye 2/3 yevhoriyamu yelead-acid bhatiri, uye huremu i1/3 yelead-acid bhatiri.
6. Kuchengetedza kwezvakatipoteredza
Lithium iron phosphate mabhatiri anowanzoonekwa seasina simbi inorema uye isingawanzo simbi (nickel-metal hydride mabhatiri anoda isingawanzo simbi), isina-chepfu (SGS yakasimbiswa), isingasvibise, inoteerana neEuropean RoHS mirau, uye ndeye mhedziso. green bhatiri chitupa.Naizvozvo, chikonzero nei iyo lithium bhatiri inofarirwa neindasitiri inonyanya kukonzerwa nekuchengetedzwa kwezvakatipoteredza.Naizvozvo, bhatiri rakabatanidzwa mu "863" yenyika yepamusoro-soro chirongwa chekusimudzira panguva ye "Gumi-Makore Mashanu Chirongwa" nguva, uye yave chirongwa chakakosha chinotsigirwa nekukurudzirwa nenyika.Nekupinda kweChina muWTO, huwandu hwekutengesa kunze kwemabhasikoro emagetsi eChina huchawedzera nekukurumidza, uye mabhasikoro emagetsi anopinda muEurope neUnited States ave kudiwa kuti ange aine mabhatiri asingasvibise.
Nekudaro, dzimwe nyanzvi dzakataura kuti kusvibiswa kwezvakatipoteredza kunokonzerwa nemabhatiri e-lead-asidhi kunowanzoitika mune isiri-yakajairwa kugadzirwa maitiro uye kudzokorodza maitiro emabhizinesi.Nenzira imwecheteyo, mabhatiri e-lithium ndeemagetsi matsva, asi haigoni kudzivisa dambudziko rekusvibiswa kwesimbi inorema.Lead, arsenic, cadmium, mercury, chromium, nezvimwewo mukugadzirisa zvinhu zvesimbi zvinogona kuburitswa muguruva nemvura.Bhatiri pacharo ikemikari, saka inogona kukonzera marudzi maviri ekusvibiswa: imwe inzira yekusvibisa tsvina mupurojekiti yekugadzira;imwe yacho ndeyekusvibiswa kwebhatiri mushure mekuraswa.
Lithium iron phosphate mabhatiri anewo zvikanganiso zvawo: semuenzaniso, yakaderera tembiricha kuita kwakashata, density yepombi yezvinhu zvakanaka electrode yakaderera, uye huwandu hwemabhatiri e lithium iron phosphate akaenzana masimba akakura kupfuura emabhatiri e lithium ion akadai se lithium. cobalt oxide, saka haina zvakanakira mumabhatiri madiki.Kana yakashandiswa mumabhatiri emagetsi, lithium iron phosphate mabhatiri, semamwe mabhatiri, inoda kutarisana nedambudziko rekusimba kwebhatiri.
