Muchimiro chekristaro cheLifepo4, atomu yeokisijeni yakanyatsoiswa mumapato matanhatu.PO43-tetraonal uye FEO6 octopus inoumba skeleton yenzvimbo yekristaro.LI neFe zvinotora mukaha uripakati peoctopus, uye P inotora mukaha wetetraonal.Iyo FE inogara yakajairwa pakona chinzvimbo cheoctopus, uye li inogara kune yakajairika divi reoctopus.Iyo FEO6 octopus yakabatana kune imwe neimwe pane BC pamusoro pekristaro, uye iyo Li6 octopus chimiro paB -axis direction yakabatana mune chetani chimiro.1 Feo6 octopus uye 2 LiO6 octopus uye 1 PO43-tetraonal co-edge.
Nekuda kwekusaenderera mberi kweFEO6 co-edge octopus network, iyo yemagetsi conductivity haigone kuumbwa;panguva imwecheteyo, PO43-tetraon inogumira kuhuwandu hwekuchinja kwelatiti, iyo inokanganisa kupera kwemvura uye kupararira kwemagetsi kweLI +, iyo inotungamirira kumagetsi ekugadzirisa uye ion diffusion yeLIFEPO4 yakanaka zvinhu zvinhu uye kupararira kweion.Kushanda zvakanaka kwakaderera zvakanyanya.
Iyo theoretical kupfuura Lifepo4 bhatiri yakakwirira (inenge 170mAh/g), uye yekuburitsa chikuva 3.4V.LI + Retinate simba pakati peyakanaka uye isina kunaka bipolar kuti ishandise kuchaja uye kuburitsa, uye iyo oxidation reaction inoitika panguva yekuchaja.Li + inofamba kubva padanda rakanaka, rakaiswa mubato rakashata kuburikidza ne electrolyte, uye simbi yakashanduka kubva kuFe2 + kusvika kuFe3 +, uye oxidation reaction yakaitika.
Rutivi rworuboshwe rwe lithium iron phosphate bhatiri ndiyo yakanaka electrode inoumbwa ne lifpo4 zvinhu zvemuorivhi chimiro, iyo yakabatana kune yakanaka electrode yebhatiri nealuminium foil.Kurudyi kune electrode yakaipa yebhatiri inoumbwa nekabhoni (graphite), iyo yakabatana neiyo negative electrode yemhangura foil nebhatiri.Pakati pane diaphragm yepolymer, iyo inoparadzanisa electrode yakanaka kubva kune electrode yakaipa.Iyo lithium ion inogona kuva maerekitironi kuburikidza nediaphragm uye haigoni kudarika diaphragm.Bhatiri rinochajwa ne electrolytes, uye bhatiri rakavharirwa negoko resimbi.
Iyo yekuchaja uye yekuburitsa mhinduro yelithium iron phosphate mabhatiri iri pakati peLifepo4 neFEPO4.Munguva yekuchaja, iyo LIFEPO4 zvishoma nezvishoma yakaparadzaniswa kubva kune lithium ion kuita FEPO4.Munguva yekuburitsa, iyo lithium ion yakamisikidzwa FEPO4 kuita LIFEPO4.
Munguva yekuchaja kwebhatiri, lithium ions inotamiswa kubva kusimbi phosphate makristasi kuenda pamusoro pekristaro.Pasi pesimba remunda wemagetsi, pinda mu electrolyte, wozopfuura nepakati pe diaphragm, uye wozotamira kune pamusoro pe graphite crystal kuburikidza ne electrolyte, uye wozoiswa mukati me graphite lattice.
Panguva imwecheteyo, iyo yemagetsi conductive aluminium foil muunganidzi electrode inoyerera ichienda kune yakanaka electrode, uye iyo yemhangura foil muunganidzi inoyerera nepakati nenzeve, bhatiri positive column, rekunze redunhu, negative electrode column, uye nzeve dzisina kunaka kune bhatiri negative electrode, uye zvino inoyerera ichienda kune litteria negative electrode , Ita iyo negative electrode charge to balance.Lithium ions inoshandurwa kuita iron phosphate mushure me lithium iron phosphate dehydrated.
Kana bhatiri rapera, lithium ions inobviswa kubva mu graphite crystal, inopinda mu electrolyte, yobva yapfuura nepakati pe diaphragm, inotamira pamusoro pe lithium iron phosphate kuburikidza ne electrolyte, uye yozoiisa zvakare mumucheka we lithium. iron phosphate.
Panguva imwecheteyo, muunganidzi wemhangura yemhangura inoyerera ichienda kune yakashata yemagetsi emeridian, kuburikidza nearuminiyamu foil muunganidzi wealuminium foil yepolar nzeve, iyo yakaipa koramu yebhatiri, rekunze redunhu, iyo yakanaka pole column, uye. iyo yakanaka polar nzeve kubhatiri.Lithium positive poles anoita kuti positive charge isvike pachiyero.Lithium ions yakanyudzwa mushure mesimbi phosphate makristasi, uye iron phosphate inoshandurwa kuita lithium iron phosphate.
