Kuchengetedza magetsilithium iron phosphate mabhatirianoshandiswa zvakanyanya mumunda wekuchengetedza simba, asi hapana mabhatiri akawanda anogona kunyatsoita kuti ishande yakadzikama kwenguva yakareba. Upenyu chaihwo hwebhatiri ye-lithium-ion inokonzerwa nemhando dzakasiyana-siyana, kusanganisira maitiro emuviri wesero, kutonhora kwemhepo, kushandisa nzira nezvimwe zvakadaro. Pakati pavo, hunhu hwemuviri hwesero hune simba guru pahupenyu chaihwo hwemabhatiri e-lithium-ion. Kana hunhu hwemuviri hwesero husina kusangana nemamiriro chaiwo kana kana bhatiri ine mamwe matambudziko panguva yekushandiswa, ichakanganisa hupenyu hwayo chaihwo uye basa chairo.
1. Kuwandisa mari
Pasi pekushandiswa kwakajairika, nhamba yekuchaja kutenderera kwelithium iron phosphate bhatiriinofanira kuva 8-12 nguva, zvikasadaro zvichaita overcharging. Kuwedzeresa kuchaita kuti iyo inoshanda yesero ipedze mukuburitsa uye kutadza. Hupenyu hwesevhisi hunodzikira sezvo huwandu hwebhatiri hunodzikira zvishoma nezvishoma. Panguva imwecheteyo, kudzika kwekuchaja kwakanyanya kunotungamira kukuwedzera polarization, kuwedzera kuparara kwebhatiri uye kupfupisa hupenyu hwebhatiri; kuwandisa kuchakonzera kuparara kwe electrolyte uye kuwedzera kukora kwemukati me electrochemical system yebhatiri. Naizvozvo, hudzamu hwekuchaja hunofanirwa kudzorwa panguva yekushandiswa kwebhatiri kudzivirira kuwandisa.
2. Sero yebhatiri yakakuvadzwa
Lithium iron phosphate bhatirimukushandiswa chaiko kunozokanganiswawo nemamiriro ekunze. Semuenzaniso, nekukanganisa kana zvinhu zvevanhu, senge pfupi-dunhu kana kuora kwesimba mukati mepakati; musimboti mukuchaja uye kuburitsa maitiro nekunze voltage, tembiricha, zvichikonzera kukanganisa kwemukati, kukukurwa kwezvinhu zvemukati, nezvimwewo. Mukuita kwekushandisa bhatiri discharge capacity decay phenomenon inoda kubhadhariswa nenguva, kana ichirambidzwa deflate charger inofanira kuburitswa kutanga mushure mekuchaja; sero iri mukuita kubhadharisa uye kuburitsa abnormalities inofanira kumira kubhadharisa kana kutsiva sero nenguva yakarebesa pasina kushandisa kana kuchaja nekukurumidza kunokonzeresa chimiro chemukati chebhatiri kukuvadzwa deformation uye kutungamirira mukurasikirwa kwemvura. Uye zvakare, iwe unofanirwa kutarisisa kumhando yemasero ebhatiri uye nyaya dzekuchengetedza uye zvimwe zvinhu pahupenyu hwebhatiri uye basa.
3. Hupenyu hwebhatiri husina kukwana
Iyo yakaderera tembiricha yemonomer inotungamira kupfupi sero hupenyu, kazhinji, iyo monomer mukushandiswa kweiyo tembiricha tembiricha haigone kudzika kupfuura 100 ℃, kana tembiricha yakadzikira kupfuura 100 ℃ inotungamira mukufambiswa kwema electron mukati me. sero kubva cathode kusvika anode, zvichiita kuti bhatiri maerekitironi haagoni zvinobudirira muripo, zvichikonzera kuwedzera sero kukwanisa kuora, zvichiita bhatiri kukundikana (simba density kuderedza). Shanduko mumagadzirirwo emagetsi emonomer inokonzeresa kuramba kwemukati, kushanduka kwevhoriyamu uye shanduko yemagetsi, nezvimwewo zvinokanganisa hupenyu hwebhatiri, mazhinji ebhatiri e lithium iron phosphate anoshandiswa mumunda wekuchengetedza simba ibhatiri rekutanga, bhatiri rechipiri. kana matatu mabhatiri masisitimu anoshandiswa pamwechete. Sekondari bhatiri system hupenyu hupfupi uye kutenderera nguva kushoma (kazhinji 1 kusvika 2 nguva) mushure mekuda kutsiva, izvo zvinowedzera bhatiri pacharo mari yekushandisa uye matambudziko ekusvibiswa kwechipiri (iyo yakadzikira tembiricha mukati mesero inoburitsa simba rakawanda uye kuita bhatiri voltage kudonha) mukana; Hutatu mune imwe bhatiri system hupenyu hwakareba uye kutenderera nguva yakawanda (kusvika makumi ezviuru zvenguva) mushure memubhadharo mukana (uchienzaniswa neternary lithium bhatiri) (ine yakanyanya simba density). Hupenyu hupfupi hwesevhisi uye mitsetse shoma pakati pesero rimwe chete ichava nekudonha kwesimba rakakura (izvi zvinokonzerwa nekushomeka kwemukati kwesero rimwe chete) kuunza kupikisa kwemukati kwebhatiri; hupenyu hurefu hwebasa uye humwe hutenderedzwa pakati pesero rimwe chete huchaita kuti kupikisa kwemukati kwebheteri uye kuderedza simba rayo remagetsi (izvi zvinokonzerwa nekati pfupi yemukati yebheteri) kukonzera kudonha kwesimba remagetsi.
4. The ambient tembiricha yakanyanyisa uye yakaderera, ichakanganisawo hupenyu hwebhatiri.
Lithium-ion mabhatiri haana chaanoita pakufambiswa kwelithium ion mutembiricha yekushanda, asi kana tembiricha yeambient yakanyanya kana kuderera, density yechaji pamusoro pelithium ion inodzikira. Sezvo density yechaji ichidzikira zvinotungamira kune lithium ions mune iyo negative electrode pamusoro deembedding uye discharge. Kurebesa nguva yekubuda, zvinoita kuti bhatiri riwedzere kuzara kana kubuda zvakanyanya. Naizvozvo, bhatiri rinofanirwa kunge riine nzvimbo yakanaka yekuchengetera uye inonzwisisika yekuchaja mamiriro. Kazhinji kutaura, tembiricha yemukati inofanirwa kudzorwa pakati pe25 ℃ ~ 35 ℃ kusapfuudza 35 ℃; iyo yekuchaja ikozvino haifanire kunge iri pasi pe10 A/V; kusapfuudza maawa makumi maviri; mutero wega wega unofanirwa kuburitswa 5 ~ 10 nguva; iyo yakasara simba haifaniri kudarika 20% yehuwandu hwehuwandu mushure mekushandisa; usachengete tembiricha iri pasi pe5 ℃ kwenguva yakareba mushure mekuchaja; iyo bhatiri seti haifanirwe kunge iri pfupi-inotenderera kana kupiswa kunze panguva yekuchaja uye yekuburitsa bhatiri paki haifanirwe kunge ipfupi-inotenderera kana kupiswa panguva yekuchaja uye kuburitsa.
5. Kuita kusina kunaka kwebheteri sero kunokonzera kuderera kwehupenyu uye kushandiswa kwesimba shoma mukati mebheteri sero.
Mukusarudzwa kwezvinhu zvecathode, mutsauko mukuita kwecathode zvinhu unokonzera akasiyana simba rekushandisa bhatiri. Kazhinji, kurebesa kwehupenyu hwebhatiri, kunowedzera simba reyero yesimba reiyo cathode zvinhu uye kukwira kwereshiyo yesimba reyero yemonomeri, kunowedzera simba rekushandisa mukati mebhatiri. Nekudaro, nekuvandudzwa kwe electrolyte, kuwedzera kwemukati kunowedzera, nezvimwewo, iyo simba density yakakwira uye monomer simba density yakadzikira, inova nemhedzisiro pakuita kwebhatiri cathode zvinhu. Iyo yakakwirira yehuwandu hwe nickel uye cobalt zvinhu mu cathode zvinhu, iyo yakakwirira mukana wekugadzira mamwe oxides mu cathode; nepo mukana wekugadzira oxides mu cathode idiki. Nekuda kwechiitiko ichi, iyo cathode zvinhu zvine yakakwira yemukati kuramba uye nekukurumidza vhoriyamu yekuwedzera mwero, nezvimwe.
