Bhatiri reLithiumibheteri rinoshandisa simbi yelithium kana kuti lithium compound se electrode. Nekuda kwepuratifomu ine voltage yakakwira, huremu hushoma uye hupenyu hurefu hwebasa re lithium, bhatiri re lithium rave rudzi rukuru rwebhatiri rinoshandiswa zvakanyanya mumagetsi evatengi, masisitimu ekuchengetera simba, mota dzemagetsi nedzimwe nzvimbo. Nhasi, ngationgororei matanho mashoma ekupedzisira ekugadzira mabhatiri e lithium, Formation-OCV testcapacity-Separation.
Kuumbwa
Kugadzirwa kwebhatiri reLithium ndiyo nzira yekutanga yekuchaja bhatiri mushure mekunge bhatiri reLithium razadzwa nemvura.
Maitiro aya anogona kumutsa zvinhu zvinoshanda mubhatiri uye kumutsabhatiri re lithiamuPanguva imwe chete, munyu we lithium unoshanda pamwe chete ne electrolyte kuti ugadzire firimu re solid electrolyte interface (SEI) padivi re negative electrode re lithium battery. Firimu iri rinogona kudzivirira kuitika kwe side reactions, nokudaro richideredza kurasikirwa kwe active lithium mu lithium battery. Hunhu hweSEI hune simba guru pahupenyu hwe cycle, kurasikirwa kwekutanga kwe capacity, uye rate performance ye lithium batterys.
Kuongororwa kweOCV
OCV test kuyedzwa kwevoltage ye open circuit, AC internal resistance uye shell voltage ye cell imwe chete. Ichi chikamu chakakosha kwazvo chekugadzirwa kwebhatiri. Inofanira kusangana neOCV accuracy ye 0.1mv uye shell voltage accuracy ye 1mv. OCV test inoshandiswa kurongedza masero.
Maitiro ekugadzira bvunzo dzeOCV
OCV bvunzo inonyanya kuyera hunhu hwebhatiri nekudzvanya maprobes akabatana nevoltage tester uye internal resistance tester panzeve dzakanaka nedzisina kunaka dzebhatiri resoft pack.
Bvunzo yeOCV iripo ikozvino inonyanya kuitwa semi-automatic test. Mushandi anoisa bhatiri nemaoko mumudziyo wekuyedza, uye probe yemudziyo wekuyedza inosangana nenzeve dzakanaka nedzisina kunaka dzebhatiri kuti iite OCV test pabhatiri, uye obva aburitsa bhatiri nemaoko orongedza.
Kupatsanurwa kwesimba rebhatiri reLithium
Mushure meboka remabhatiri e lithiamuZvakagadzirwa, kunyangwe saizi yacho yakafanana, kugona kwemabhatiri kuchasiyana. Saka, anofanira kuchajwa zvizere pamudziyo zvichienderana nezvinodiwa, uye obva aburitswa (aburitswa zvachose) zvichienderana nemagetsi akatarwa. Nguva inotorwa kuburitsa bhatiri zvakazara zvakawedzerwa nemagetsi ekuburitsa ndiyo kugona kwebhatiri.
Chero bedzi simba rakaedzwa richisvika kana kupfuura simba rakagadzirwa, bhatiri re lithium rinokwanisa, uye bhatiri rine simba risingasviki simba rakagadzirwa harigone kunzi bhatiri rinokwanisa. Maitiro aya ekusarudza mabhatiri akakodzera kuburikidza nekuyedza simba anonzi kupatsanura simba.
Basa rebhatiri re lithiamuKupatsanurana kwesimba hakungobatsiri chete pakugadzikana kwefirimu reSEI, asiwo kunogona kupfupisa nguva inopedzwa nemaitiro ekupatsanurana simba, kuderedza kushandiswa kwesimba uye kuwedzera kugona kwekugadzira.
Chimwe chinangwa chekupatsanura mabhatiri ndechekuisa mumapoka uye kuisa mabhatiri mumapoka, kureva kuti, kusarudza mamonomer ane resistance yemukati yakafanana uye kugona kusanganisa. Pakubatanidza, avo chete vane performance yakafanana ndivo vanogona kugadzira bhatiri.
Mhedziso
Pakupedzisira,bhatiri re lithiamuapedza zvese zvinoitwa nebhatiri mushure mekuongororwa kwakazara, kupfapfaidza kodhi yegiredhi, kuongororwa kwekuongorora giredhi, uye kurongedza, achimirira kuunganidzwa mubhatiri.
Nezvemabhegi emabhatiri, kana uine pfungwa yemabhegi emabhatiri akagadzirwa nemaoko, Heltec inopavanoedza kugona kwebhatirikuti unzwisise maparamita ebhatiri rako uye kuti ufunge kana zvakakodzera kubatanidza paki yebhatiri yaunoda. Tinokupawochiyereso chebhatirikuchengetedza mabhatiri ako ekare uye kuenzana kwemabhatiri nekuchaja zvisina kuenzana uye kuburitsa mvura zvisina kuenzana kuti bhatiri rishande zvakanaka uye rigare kwenguva refu.
Heltec Energy ndiyo shamwari yako yaunovimba nayo mukugadzira mabheteri. Nekutarisa kwedu kutsvagurudzo nekuvandudza, pamwe chete nemidziyo yedu yakawanda yemabhatiri, tinopa mhinduro dzese kuti tisangane nezvinodiwa zviri kuchinja muindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa vatengi, uye hukama hwakasimba nevatengi zvinoita kuti tive sarudzo yakanaka kune vagadziri vemabheteri nevatengesi pasi rese.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
