Lithium roj teeb aluminium ntawv ci
Cov roj teeb lithium yog tsim los ntawm cov khoom siv hluav taws xob zoo tam sim no (tam sim no cov khoom siv hluav taws xob), lub thawv, lub phaj sealing, lub phaj tsis zoo, thiab lwm yam. ua tiaj; cov khoom siv lub thawv yuav tsum muaj lub zog siab thiab formability, nrog rau kev nthuav dav zoo; cov ntaub ntawv sealing yuav tsum muaj zoo Formability thiab laser weldability; laminated ntim cov ntaub ntawv txhuas yuav tsum muaj lub zog siab thiab tsim tau; busbar cov ntaub ntawv yuav tsum muaj siab zog thiab conductivity, nrog rau zoo dabtsi yog khoov processability.
Lub roj teeb txhuas ntawv nyiaj peb feem ntau xa mus rau cov lithium-ion roj teeb zoo electrode foil. Qhov no yeej tsis yog txaus. Nws yog qhov zoo tshaj plaws los hu rau qhov tsis hloov pauv zoo electrode foil nrog lub thickness ntawm li 0.1mm raws li tam sim no collector txhuas ntawv ci kom paub qhov txawv ntawm lithium (ion) Lwm cov ntawv txhuas txhuas siv rau cov roj teeb, xws li foils hauv txhuas. -plastic films rau roj teeb mos pob, tab foils, hloov carbon-coated foils, thiab lwm yam. Ntawm ib sab, tam sim no collector aluminium foil yog tam sim no collector electrode, thiab ntawm qhov tod tes, nws yog cov cab kuj ntawm qhov zoo los yog tsis zoo. cov ntaub ntawv electrode ntawm lithium roj teeb, uas yog, cov khoom siv roj teeb lithium yuav tsum tau coated rau nws. Qhov tseeb, tam sim no cov khoom siv aluminium ntawv ci tuaj yeem raug xa mus ua cov ntawv ci roj teeb.
Zoo electrode qauv
Qhov zoo electrode yog tsim los ntawm qhov zoo electrode tam sim no collector (pole tab), high-temperature tape, zoo electrode matrix thiab zoo electrode khoom. Cov ncej ncej yog hais txog 0.1 hli alloy ntawv ci xws li 1070, 1060, 1235, 1230, 1100, 8011, 1N30, 3003, thiab lwm yam. Cov khoom siv feem ntau yog 1235, 1070, 1100, thiab 3003 alloys vim lawv lub zog siab. Qhov zoo electrode substrate yog cov ntawv ci kwv yees li 0.016mm tuab.
Plhaub thiab sealing cov ntaub ntawv
Lub plhaub yog ua los ntawm nyias aluminium daim hlau, uas yuav tsum tau muaj siab formability thiab lub zog, thiab yuav tsum muaj lub siab ua hauj lwm zoo heev tiv thaiv lub plhaub expansion tshwm sim los ntawm kev rov them thiab tawm. Cov khoom ntawm peb lub plhaub phaj yog qhia hauv lub rooj.
Lub foob yog laser welded, yog li nws yuav tsum tau zoo heev laser weldability. Nyob rau tib lub sijhawm, tsis muaj kev ua haujlwm loj yuav tshwm sim thaum lub sijhawm ua haujlwm ntawm qhov tawg-pov thawj valve, thiab nws yuav tsum muaj qhov zoo formability. Cov khoom sib txawv ntawm cov khoom sib khi yog qhia hauv lub rooj.
roj teeb ntawv ci
Muaj ob hom ntawv txhuas rau cov roj teeb lithium-ion: cov ntawv ci, uas muaj lub zog siab, siab conductivity thiab flatness; thiab nto-hloov ntawv ci. Muaj xya hom pav ca foils tsim los ntawm Nyiv United Aluminium Company: A85, C2F, siab zog C2F, FS115, MS812, X383, thiab 503S. Ntawm lawv, A85, C2F, thiab 503S yog cov ntawv xov xwm dav dav uas tuaj yeem siv rau ntau yam pej xeem. , Los ntawm roughening saum npoo, adhesion ntawm cov khoom siv tau zoo heev. Tib lub sijhawm, cov nplaum nplaum tuaj yeem txo qis, thiab cov yam ntxwv ntawm cov roj teeb kuj tseem txhim kho. Kev siv cov txheej txheem roughening tshiab txo cov nqi tsim khoom piv nrog cov txheej txheem ib txwm muaj. Cov khoom ntawm cov ntaub ntawv tiaj tus alloys tau qhia hauv lub rooj.
Aluminium busbar alloy
Lub busbar conductive ntawm lithium roj teeb yog Ameslikas ua los ntawm Cu. Tom qab hloov mus rau aluminium, nws tsis tsuas yog ua tiav qhov hnyav ntawm qhov hnyav, tab sis kuj txo tus nqi; cov conductivity ntawm EC1 alloy yog tib yam li cov ntshiab txhuas 1050-O, tab sis nws lub zog yog ntau tshaj nws 50%; Cov hluav taws xob conductivity ntawm EC2 alloy tsuas yog 57% ntawm tooj liab. Yog hais tias lub busbar phaj thickness tau nce mus rau 1.8 npaug ntawm Cu, qhov ua tau tam sim no tuaj yeem sib npaug ntawm tooj liab.
