Iri zita rakazara reti lithium iron phosphate bhatiri inonzi lithium iron phosphate lithium ion bhatiri, iyo inoreva lithium ion bhatiri inoshandisa lithium iron phosphate seyakanaka electrode zvinhu. Kune akawanda marudzi emhando dzecathode mabhatiri e lithium-ion mabhatiri, kunyanya lithium cobalt oxide, lithium manganate, lithium nicklate, ternary zvinhu, lithium iron phosphate uye zvichingodaro. Pakati pavo, lithium cobalt oxide parizvino ndiyo cathode zvinhu zvinoshandiswa mumabhatiri mazhinji e-lithium-ion, nepo zvimwe zvinhu zvecathode zvisina kugadzirwa zvakanyanya pamusika nekuda kwezvikonzero zvakasiyana. Lithium iron phosphate zvakare imwe yemabhatiri e-lithium-ion. Panyaya yemusimboti wezvinhu, lithium iron phosphate zvakare iri intercalation / deintercalation process, iyo yakangofanana ne lithium cobaltate uye lithium manganate.

Lithium iron phosphate mabhatiri ari lithium-ion sekondari mabhatiri. Imwe yekushandiswa kwayo kukuru ndeye bhatiri remagetsi. Iyo ine mabhenefiti makuru pamusoro peNI-MH uye Ni-Cd mabhatiri.

Chazvakanakira

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. Mumwe mushumo wakaratidza kuti mukushanda chaiko kweacupuncture kana kupfupika kwedunhu kuedza, chikamu chidiki chemasampuli chakawanikwa chichipisa, asi hapana kuputika kwakaitika. Mukuedza kwekuwandisa, kuchaja kwemagetsi kwakapetwa kakati wandei kupfuura kudzima kwemagetsi kwakashandiswa, uye zvakaonekwa kuti pachine chiitiko cheKuputika. Zvakadaro, kuchengetedzeka kwayo kwekuwedzeredza kwakavandudzwa zvakanyanya kana zvichienzaniswa neyakajairwa mvura electrolyte lithium cobalt oxide mabhatiri.

2, kuvandudzwa kwehupenyu hurefu

“Lithium iron phosphate battery” inoreva bhatiri re lithium ion rinoshandisa lithium iron phosphate sechinhu chakanaka che electrode.

Upenyu hwehupenyu hwehupenyu hurefu hunotungamira-asidhi bhatiri inenge ka300, uye iyo yakakwirira ndeye 500 nguva, nepo lithium iron phosphate power bhatiri ine hupenyu hwekutenderera hwenguva dzinopfuura 2000, uye inogona kushandiswa kwe2000 nguva chiyero chechaji (5 maawa chiyero). Lead-asidhi mabhatiri emhando imwechete “itsva hafu yegore, hafu yegore, uye hafu yegore yekugadzirisa”, iyo inogona kutora kusvika ku1 kusvika kumakore 1.5. Kana yakashandiswa pasi pemamiriro akafanana, lithium iron phosphate mabhatiri ane hupenyu hwekufungidzira hwemakore manomwe kusvika masere. Kutarisisa kwakadzama, chiyero chekuita-mutengo chinoti inopfuura kane kane iyo yemabhatiri e-lead-asidhi. Kubuda kwepamusoro-ikozvino kunogona kukurumidza kuchaja uye kuburitsa yakakwira-ikozvino 7C. Nejaja yakatsaurirwa, bhatiri rinogona kuzara mukati memaminitsi makumi mana e8C kuchaja, uye kutanga ikozvino kunogona kusvika 4C, asi mabhatiri e-lead-acid haana kuita kwakadaro.

3, yakanaka tembiricha kuita

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, lithium iron phosphate electric heat peak inogona kusvika 350 ℃-500 ℃, nepo lithium manganate uye lithium cobaltate inongotenderedza 200 ℃.

4, hukuru hukuru

∩Kugona kwemabhatiri ekuchajiswa kuchadzikira nekukasira pane yakayerwa huwandu kana achiwanzochajiwa uye asingabudiswe. 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 kuchajwa uye kushandiswa pasina kutanga wariburitsa.

6, uremu huremu

Vhoriyamu yebhatiri yelithium iron phosphate yezvakafanana uye kugona ndeye 2/3 yevhoriyamu yelead-acid bhatiri, uye huremu ndeye 1/3 yelead-acid bhatiri.

7, kuchengetedzwa kwezvakatipoteredza

Lithium iron phosphate mabhatiri anowanzoonekwa seasina simbi inorema uye isingawanzo simbi (iyo nickel-hydrogen bhatiri inoda simbi isingawanzo), isina-chepfu (SGS yakasimbiswa), isingasvibise, inoenderana neEuropean RoHS mirau, uye yakasvibira yakazara. bhatiri chitupa. Naizvozvo, chikonzero nei mabhatiri e-lithium achifarirwa neindasitiri inonyanya kukonzerwa nekuchengetedzwa kwezvakatipoteredza. Nokudaro, bhatiri yakabatanidzwa mu “863” yenyika yepamusoro-soro chirongwa chekusimudzira munguva ye “Gumi reKuronga Kwemakore mashanu” uye yakava purojekiti inokosha yenyika uye kukurudzira. Nekupinda kweChina kuWTO, huwandu hwemabhasikoro emagetsi eChina hunotengeswa kunze kwenyika huchawedzera nekukurumidza, uye mabhasikoro emagetsi anopinda muEurope nekuUnited States ave kudiwa kuti ange aine mabhatiri asingasvibise.

Asi dzimwe nyanzvi dzakataura kuti kusvibiswa kwezvakatipoteredza kunokonzerwa nemabhatiri e-lead-asidhi kunonyanya kuitika mukugadzirwa kwekambani kusingaenzaniswi uye kudzokororwazve. 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 pachayo imhando yemakemikari zvinhu, saka zvinokwanisika kugadzira marudzi maviri ekusvibisa: imwe ndeyekusvibiswa kwemaitiro tsvina mukugadzira engineering; imwe yacho kusvibiswa kwebhatiri mushure mekunge raraswa.

Lithium iron phosphate mabhatiri anewo zvikanganiso zvawo: semuenzaniso, kushomeka kwekushisa-kuderera, kuderera kwepombi density yezvinhu zvecathode, uye huwandu hwebhatiri relithium iron phosphate rehuwandu hwakaenzana hwakakura pane hwemabhatiri e lithium-ion se lithium. cobalt oxide, saka haina mukana mune micro-mabhatiri. Kana ichishandiswa mumabhatiri emagetsi, lithium iron phosphate mabhatiri, semamwe mabhatiri, anofanirwa kutarisana nenyaya dzebhatiri.
