Lithium bhatiriibhatiri rinoshandisa lithium simbi kana lithium compound se electrode material. Nekuda kweiyo yakakwira voltage platform, huremu huremu uye hupenyu hurefu hwesevhisi yelithium, lithium bhatiri yave rudzi rukuru rwebhatiri rinoshandiswa zvakanyanya mumagetsi evatengi, masisitimu ekuchengetedza simba, mota dzemagetsi nemimwe minda. Nhasi, ngationgororei matanho mashoma ekupedzisira ekugadzira lithium bhatiri, Formation-OCV testcapacity-Separation.
Formation
Lithium bhatiri kuumbwa ndiyo yekutanga kuchaja maitiro ebhatiri mushure mekunge lithium bhatiri razadzwa nemvura.
Iyi nzira inogona kumisa zvinhu zvinoshanda mubhatiri uye kuita iyolithium bhatiri. Panguva imwecheteyo, iyo lithium salt inopindirana ne electrolyte kuumba yakasimba electrolyte interface (SEI) firimu pane negative electrode side re lithium battery. Iyi firimu inogona kudzivirira kuwedzera kuitika kwemaitiro emativi, nekudaro kuderedza kurasikirwa kweiyo inoshanda lithium mubhatiri re lithium. Hunhu hweSEI hune simba guru pahupenyu hwekutenderera, kurasikirwa kwekutanga kwesimba, uye chiyero chekuita kwemabhatiri e lithium.
OCV bvunzo
OCV bvunzo bvunzo yeyakavhurika redunhu voltage, AC yemukati kuramba uye goko remhepo yesero rimwe chete. Icho chikamu chakakosha zvikuru chekugadzirwa kwebhatiri. Inoda kusangana neOCV kurongeka kwe0.1mv uye iyo shell voltage kurongeka kwe1mv. Iyo OCV bvunzo inoshandiswa kugadzirisa maseru.
OCV bvunzo yekugadzira maitiro
OCV bvunzo inonyanya kuyera maitiro ebhatiri nekutsikirira maprobes akabatana nevoltage tester uye yemukati yekupikisa tester panzeve dzakanaka uye dzisina kunaka dzesoft pack bhatiri.
Ikozvino OCV bvunzo inonyanya kuita semi-otomatiki bvunzo. Mushandi anoisa bhatiri nemaoko mumudziyo wekuyedza, uye probe yechishandiso chekuyedza inosangana nenzeve dzakanaka uye dzisina kunaka dzebhatiri kuti aite bvunzo yeOCV pabhatiri, uyezve anoburutsa nekugadzirisa bhatiri.
Lithium bhatiri kugona kupatsanura
Mushure mechikamu chelithium mabhatirianogadzirwa, kunyangwe saizi yakafanana, kugona kwemabhatiri kuchave kwakasiyana. Naizvozvo, ivo vanofanirwa kubhadhariswa zvizere pamidziyo zvinoenderana nezvakatsanangurwa, vobva vaburitswa (kuburitswa zvachose) zvinoenderana neyakatsanangurwa ikozvino. Nguva inotorwa kuburitsa bhatiri yakapetwa zvakazara nekubuda ikozvino ndiko kugona kwebhatiri.
Chero bedzi simba rakaedzwa richisangana kana kudarika simba rakagadzirwa, lithiamu bhatiri inokodzera, uye bhatiri ine zvishoma kudarika yakagadzirirwa simba haigoni kuonekwa sebheteri inokodzera. Iyi nzira yekusarudza mabhatiri akakodzera kuburikidza nekuyedzwa kwehuwandu hunodaidzwa kuti kupatsanura simba.
Basa relithium bhatirikupatsanurwa kwesimba hakusi kungobatsira chete kugadzikana kweiyo SEI firimu, asi zvakare inogona kupfupisa nguva inopedzwa nemaitiro ekugovera, kuderedza kushandiswa kwesimba uye kuwedzera kugadzirwa kwesimba.
Chimwe chinangwa chekugovera masimba ndechekuisa nemapoka mabhatiri, ndiko kuti, kusarudza mamonomeri ane imwechete yemukati kuramba uye kugona kwekusanganisa. Kana uchibatanidza, avo chete vane maitiro akafanana vanogona kugadzira bhatiri pack.
Mhedziso
Pakupedzisira, thelithium bhatiriyapedza maitiro ese ebhatiri sero mushure mekutarisa kwakazara kutaridzika, giredhi kodhi kupfapfaidza, giredhi scanning yekuongorora, uye kurongedza, yakamirira kuunganidzwa mubhatiri pack.
Nezve bhatiri mapaketi, kana uine pfungwa yeDIY bhatiri mapaketi, Heltec inopabhatiri capacity testerskukuita kuti unzwisise bhatiri yako paramita uye funga kana yakakodzera kuunganidza bhatiri paki yaunoda. Isu tinopawobhatiri yakaenzanakuchengetedza mabhatiri ako ekare uye kuenzanisa mabhatiri nechaji isina kuenzana uye kuburitsa kuti uvandudze kushanda kwebhatiri uye hupenyu.
Heltec Energy ishamwari yako yaunovimba nayo mukugadzira bhatiri pack. Nekutarisa kwedu kusingagumi pakutsvaga nekusimudzira, pamwe nehupamhi hwemabhatiri ezvishandiso zvedu, tinopa mhinduro imwe chete yekusangana nezvinodiwa neindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa, uye kudyidzana kwakasimba kwevatengi kunotiita isu kuenda-kune sarudzo yevagadziri vebhatiri pack uye vatengesi pasi rese.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
