Iyo yakanaka electrode yelithium ion bhatiri inogadzirwa ne lithium iron phosphate material, iyo ine mabhenefiti makuru maererano nekuchengetedza kuita uye kutenderera hupenyu. Aya ndiwo mamwe akakosha ehunyanzvi zviratidzo zvemabhatiri emagetsi. Lifepo4 bhatiri 1C kuchaja uye kuburitsa kutenderera hupenyu kusvika ku2000 nguva, puncture haina kuputika, overcharge haisi nyore kupisa uye kuputika. Lithium iron phosphate cathode zvinhu zvinoita kuti hombe-inokwana lithium-ion mabhatiri nyore kushandisa munhevedzano.

Lithium Iron Phosphate Cathode Material

Lifepo4 bhatiri inoreva lithium ion bhatiri rinoshandisa lithium iron phosphate seyakanaka electrode zvinhu. Lithium-ion bhatiri cathode zvinhu zvinonyanya kusanganisira lithium cobalt oxide, lithium manganate, lithium nicklate, ternary zvinhu, uye lithium iron phosphate. Pakati pavo, lithium cobalt oxide ndiyo cathode zvinhu zvinoshandiswa mumabhatiri akawanda e-lithium-ion. Mumusimboti, lithium iron phosphate zvakare iri intercalation uye deintercalation process. Iyi nheyo yakafanana ne lithium cobalt oxide uye lithium manganese oxide.

Lifepo4 bhatiri mukana

1. Kuchaja kwepamusoro uye kuburitsa kushanda zvakanaka

Iyo Lifepo4 bhatiri i lithium ion yechipiri bhatiri. Imwe yemashandisirwo makuru ndeyemabhatiri emagetsi. Iyo ine mabhenefiti makuru pamusoro penickel-metal hydride uye nickel-cadmium mabhatiri. Lifepo4 bhatiri ine yakanyanya kuchaja uye yekuburitsa kunyatsoita, iyo inogona kusvika kupfuura 90% munzvimbo yakaburitswa, nepo iyo yelead-asidhi bhatiri ingangoita 80%.

2. Lifepo4 bhatiri ine yakakwirira kuchengetedza kushanda

Iyo PO bond mu lithium iron phosphate crystal yakagadzikana uye yakaoma kuparara. Kunyangwe pasi pekushisa kwepamusoro kana kuwandisa, haizoputsiki kana kupisa se lithium cobalt oxide, uye haizogadziri zvinhu zvakasimba oxidizing, saka ine kuchengeteka kwakanaka.

Zvinonzi mukushanda chaiko, nhamba shoma yemasampuli akawanikwa achipisa mu acupuncture kana pfupi-circuit bvunzo, asi hapana kuputika kwakaitika. Mukuedza kwe overcharge, high voltage charge iyo yaive yakakwira kakawanda pane yekuzvibvisa yega yakashandiswa, uye zvakaonekwa kuti pachine chiitiko chekuputika. Zvakadaro, kuchengetedzeka kwayo kwekuwandisa kunovandudzwa zvakanyanya kana ichienzaniswa neyakajairwa mvura electrolyte lithium cobalt oxide mabhatiri.

3. Lifepo4 bhatiri ine hupenyu hurefu hwekutenderera

Lifepo4 bhatiri inoreva lithium ion bhatiri rinoshandisa lithium iron phosphate seyakanaka electrode zvinhu.

Hupenyu hwekutenderera kwehurefu hwehupenyu hwelead-acid bhatiri hunenge ka300, kusvika ku500 times. Hupenyu hwekutenderera kwe lithium iron phosphate power bhatiri inodarika nguva dze2000, uye iyo standard charge (5 hour rate) inogona kusvika ka2000.

Lead-asidhi mabhatiri emhando imwe chete “hafu yegore, yekare hafu yegore, uye hafu yegore yekugadzirisa” anogona kusvika ku1 kusvika kumakore 1.5, nepo lifepo4 mabhatiri achange aine hupenyu hwekufungidzira hwemakore manomwe kusvika masere kana akashandiswa. pasi pemamiriro akafanana.

Kutarisisa kwakadzama, zvichinzi chiyero chemutengo-kushanda chinopeta nekanopfuura kana icho emabhatiri e-lead-asidhi. Kubuda kwepamusoro ikozvino kunogona kushandisa yakakwira ikozvino 2C kukurumidza kuchaja uye kuburitsa. Pasi pejaja yakakosha, bhatiri rinogona kubhadharwa zvakakwana mumaminitsi 1.5 pa 1.5C, uye kutanga ikozvino kunogona kusvika ku2C, nepo bhatiri re-lead-acid risina kuita kwakadaro.

4. Kubata kwakanaka kwekushisa

Iyo tembiricha yepamusoro yelithium iron phosphate inogona kusvika 350 ℃-500 ℃, nepo lithium manganate uye lithium cobaltate inongotenderedza 200 ℃. Yakakura yekushanda tembiricha yemhando (-20C-+ 75C), yakakwirira tembiricha kuramba, lithium iron phosphate electric heat peak inogona kusvika 350 ° C-500 ° C, nepo lithium manganate uye lithium cobaltate iri pa200 ° C chete.

5. Lifepo4 bhatiri yakakwirira

Iine simba rakakura kudarika mabhatiri akajairwa (lead-acid, nezvimwewo). Iyo monomer huwandu ndeye 5AH-1000AH.

6. Hapana ndangariro mhedzisiro

Kana iyo bhatiri rechargeable kazhinji isina kuburitswa zvizere, huwandu huchakurumidza kudonha pasi peyakayerwa huwandu. Chiitiko ichi chinonzi memory effect. Kuyeuka kwakafanana neNi-MH neNi-Cd mabhatiri, asi lifepo4 bhatiri harina chiitiko ichi. Hazvina mhosva kuti bhatiri riri mumamiriro api, rinogona kuchajwa uye kushandiswa pasina kuburitsa uye kubhadharisa.

7. Huremu hwelifepo4 bhatiri

Iyo lifepo4 bhatiri yezvakafanana uye kugona ndeye 2/3 yevhoriyamu yelead-asidhi bhatiri, uye huremu i1/3 yelead-asidhi bhatiri.

8. Lifepo4 bhatiri inoenderana nenharaunda

Bhatiri rinowanzoonekwa serisina chero simbi inorema uye isingawanzo simbi (iyo nickel-hydrogen bhatiri inoda simbi isingawanzo), isiri-chepfu (SGS certification), isingasvibise, inoenderana neEuropean RoHS mirau, uye ndeye yakasvibira. bhatiri chitupa.

Naizvozvo, chikonzero nei mabhatiri e-lithium achifarirwa neindasitiri inonyanya kukonzerwa nekufunga kwezvakatipoteredza. Nokudaro, munguva ye “Eleventh Five-Year Plan” nguva, bhatiri yakabatanidzwa mu “863” yenyika yepamusoro-soro chirongwa chekusimudzira uye yakava purojekiti inokosha yenyika uye kukurudzira.

Nekupinda kwenyika yangu kuWTO, kutengesa kwenyika yangu mabhasikoro emagetsi kuchawedzera nekukurumidza, uye mabhasikoro emagetsi achipinda muEurope neUnited States ave kudiwa kuti ange aine mabhatiri asingasvibise.

Kuita kwemabhatiri e-lithium-ion kunonyanya kuenderana nezvinhu zvakanaka uye zvisina kunaka. Lithium iron phosphate ndeye lithium bhatiri zvinhu izvo zvakangoonekwa mumakore achangopfuura. Kuchengetedza kwayo kuita uye hupenyu hwekutenderera hahuenzaniswi nezvimwe zvinhu. Iyo inonyanya kukosha tekinoroji chiratidzo chebhatiri.

Lifepo4 bhatiri ine zvakanakira kwete-chepfu, isina-kusvibisa, yakanaka kuchengetedzwa kwekuita, huwandu hwakawanda hwezvigadzirwa, mutengo wakaderera uye hupenyu hurefu. Iyo yakanaka cathode zvinhu zvechizvarwa chitsva che lithium-ion mabhatiri.
