Mumakore achangopfuura,lithium-ion mabhatiriave masimba akakosha emagetsi emhando dzakasiyana dzemagetsi.Nekudaro, kunetseka nezve kuchengetedzwa kwakatenderedza mabhatiri aya kwamutsa nhaurirano yenjodzi dzawo.Lithium Iron Phosphate (LiFePO4) ikemikari yebhatiri chaiyo yakagamuchira kutariswa nekuda kwekuchengetedzwa kwayo kwakagadziridzwa kana ichienzaniswa neyakajairwa Li-ion mabhatiri.Kusiyana nedzimwe pfungwa dzisiridzo, lithium iron phosphate mabhatiri haakonzere kuputika kana kutyisidzira moto.Muchikamu chino, isu tine chinangwa chekubvisa iyi nhema uye kujekesa maitiro ekuchengetedza eLiFePO4 mabhatiri.
Dzidza nezve lithium iron phosphate mabhatiri
LiFePO4 bhatiri iri advanced lithium-ion bhatiri rinoshandisa lithium iron phosphate se cathode material.Iyi chemistry inopa zvakakosha zvakakosha, kusanganisira yakakwira simba density, kureba kutenderera hupenyu, yakaderera yekuzviburitsa mwero, uye zvakanyanya kukosha, kuchengetedzwa kwakawedzera.Nemagadzirirwo, mabhatiri e-lithium iron phosphate anogara akagadzikana uye ane njodzi yakaderera yekutiza kwekupisa-chinhu chinogona kukonzera kuputika nemoto.
Sayenzi kuseri kweLiFePO4 bhatiri chengetedzo
Chimwe chezvikonzero zvikuru mabhatiri eLiFePO4 anonzi akachengeteka ndeyekugadzikana kwavo kwekristalline chimiro.Kusiyana nemamwe mabhatiri e-lithium-ion ane cathode zvinhu zvinosanganisira lithium cobalt oxide kana lithium nickel manganese cobalt (NMC), LiFePO4 ine hurongwa hwakasimba.Iyi crystalline chimiro inobvumira zviri nani kupisa kupisa panguva yekushanda kwebhatiri, kuderedza njodzi yekupisa uye zvinokonzeresa kutiza kwekushisa.
Pamusoro pezvo, LiFePO4 bhatiri kemikari ine tembiricha yekuparara kwepamusoro kana ichienzaniswa nemamwe maLi-ion chemistries.Izvi zvinoreva kuti LiFePO4 mabhatiri anogona kumira tembiricha yepamusoro pasina kuparara kwemafuta, ichiwedzera chengetedzo muganho mumashandisirwo akasiyana siyana.
Matanho ekuchengetedza muLiFePO4 bhatiri dhizaini
Matanho akasiyana-siyana ekuchengetedza anoshandiswa mukugadzira mabhatiri eLiFePO4 kuderedza njodzi yekuputika uye moto.Aya matanho anobatsira kuvandudza kuchengetedzwa kwese uye kuvimbika kweLiFePO4 mabhatiri.Zvimwe zvinozivikanwa zvekuchengetedza zvinosanganisira:
1. Maelectrolyte akagadzikana: Mabhatiri eLiFePO4 anoshandisa electrolytes asingabatiki, kusiyana nemagetsi e-lithium-ion mabhatiri anoshandisa organic electrolytes anopisa.Izvi zvinobvisa mukana wekutsva kwe electrolyte, izvo zvinoderedza zvakanyanya njodzi yemoto.
2. Battery management system (BMS): Imwe neimwe yeLiFePO4 bhatiri pack ine BMS, iyo ine mabasa akadai sekudzivirira kwekuwedzera, kuchengetedzwa kwakanyanya, uye kupfupika kwedunhu kudzivirira.Iyo BMS inoramba ichitarisa uye inogadzirisa bhatiri voltage, yazvino, uye tembiricha kuti ive nechokwadi chekuchengetedza uye kunyatsoita bhatiri kuita.
3. Thermal runaway kudzivirira: LiFePO4 mabhatiri haanyanyi kutarisana nekupisa kwemhepo nekuda kwemakemikari akachengeteka.Muchiitiko chechiitiko chakanyanya, lifepo4 bhatiri fekitori inowanzowedzera nzira dzekudzivirira kupisa, senge mafizi anopisa kana dzimba dzinodzivirira kupisa, kuti iwedzere kuderedza njodzi.
Zvishandiso uye zvakanakira LiFePO4 bhatiri
LiFePO4 mabhatiri anoshandiswa mumhando dzakasiyana-siyana dzemaindasitiri, kusanganisira mota dzemagetsi (EVs), chengetedzo yemagetsi, magetsi evatengi, uye kunyange michina yekurapa.Kuchengetedzeka kwavo kwakakwidziridzwa, hupenyu hurefu, uye kuvimbika kunoita kuti ive yakanakira maapplication akadai.
Mukupedzisa
Kusiyana nemafungiro asiriwo, mabhatiri eLiFePO4 haana njodzi yekuputika kana moto.Yayo yakagadzika kristaro chimiro, yakakwira yekupisa kupisa tembiricha, uye matanho ekuchengetedza anosanganisirwa mukugadzira maitiro anoita kuti ive yakachengeteka.Nekuwedzera kuri kuita kwesimba rekuchengetedza simba rekugadzirisa, lithium iron phosphate mabhatiri akaiswa seyakavimbika uye yakachengeteka sarudzo kune akasiyana maindasitiri.Mashoko asiriwo pamusoro pekuchengetedzwa kwebhatiri anofanira kugadziriswa uye ruzivo rwakakwana runosimudzirwa kuitira kuti vanhu vaite sarudzo dzine ruzivo nezvesarudzo dzemagetsi.
Kana iwe uchifarira lithium iron phosphate mabhatiri, unogamuchirwa kubata lifepo4 bhatiri fekitori Radiance kuverenga zvimwe.
