Lub ntsiab
Lithium roj teeb seplators tau ua rau muaj kev tiv thaiv kev tiv thaiv nruab nrab ntawm qhov zoo thiab tsis zoo elecodes, ua tshuaj ions tab sis tsis electrons. Qhov tsim nyog, tom qab txhaj thiab tsim, tus separator yuav tsum tuav lub zoo meej, tiaj tus haum nrog electrode. Txawm li cas los xij, feem ntau, thaum disassembling lub roj teeb, tus separator yog pom tias muaj kev sib dhos loj. (Qhov no tseem tuaj yeem pom meej meej los ntawm wrinkles ntawm qhov tsis zoo electrode.)
Cov hauv qab no tham cov ntsiab lus wrinkles hauv peb cov ntsiab lus tseem ceeb: qhov teeb meem ntawm cais tawm wrinkles, thiab cov kev daws teeb meem rau separator wrinkles.
Kev phom sij ntawm cov nyom wrinkles
Nce sab hauv kev tiv thaiv: Tus separator lub microporous lub microporous nyob rau hauv lub wrinkled cheeb tsam cuam tshuam, cuam tshuam lithium ion kev sib kis. Qhov no nce sab hauv kev tiv thaiv los ntawm 15% -30%, txo tus nqi thiab txo qis kev ua haujlwm.
Muaj peev xwm fading:Uneven electrolyte infiltration nyob rau hauv lub wrinkled ib cheeb tsam txo cov khoom siv nquag siv. Cov ntaub ntawv sim los ntawm qee cov roj teeb cathhode cathhode lub peev xwm tau ploj mus txog li 8% rau 100 mus.
Lithium plating induces luv luv:Wrinkling nce hauv lub zos tam sim no thiab qhov tshwm sim ntawm Lithium dendrite loj hlob ntawm cov graphite anode anode, nce kev pheej hmoo ntawm cov voj voog luv luv.
Ua rau Diaphragm wrinkling
Khoom tsis xws li:Wrinkles muaj feem ntau yuav tshwm sim thaum lub diaphragm nto ntau dua li 0.3μm (RA qauv tus nqi 0.1μ3) lossis lub zog tensile tsawg dua 300mpa.
Txheej Txheem Tsis Txaus:Ntau dua winding tension tensioning dhau mus ± 3% tuaj yeem ua rau Uneven electrode (cov qauv ntsuas kub ntau dua li 5 qib tsawg dua lossis sib npaug) degree), thiab lwm yam.
Tus Txheej Txheem Tsis Txaus Siab Siv:Tsis raug kub nias siab, ntsuas kub, thiab sijhawm chaw nyob tuaj yeem ua rau cov tsis zoo electrode yob tsim.
Tus Txheej Txheem Tsis Raug:Cov txheej txheem kev txhaj tshuaj feem ntau suav nrog (thawj lub tshuab nqus tsev - so {{1} {}- Lub tshuab nqus tsev thib ob. Yog tias lub tshuab nqus tsev siab dhau yog siab dhau los yog qhov ceev nrawm nrawm, sib cais ntawm lub diaphragm thiab electrode tuaj yeem tshwm sim yooj yim. Nyob rau tib lub sijhawm, roj yog tsim tom qab Pre6- pitter, thiab nqus rau cov roj hauv cov roj hauv cov roj thiab qee qhov electrolyte. Qhov no cov roj kev rho tawm tsim cov roj av thiab cov wrinkles pom.
Tsis tiav electrolyte impregnation:Cov tsis tiav pob hluav taws xob tsis tiav hauv cov chaw qhuav, cov khoob khoob, thiab ua npuas ntawm cov electrode thiab diaphragm, ua rau nws zoo rau wrinkling thaum nqus dej. Cov khoom tsis xws luag hluav taws xob: Intrinsic qhov tsis xws luag nyob rau hauv electrode (xws li pob (xws li pob thiab pits) tuaj yeem cuam tshuam cov nplaum ntawm lub diaphragm rau nws, ua rau electrode wrinkles.
Cov ntsiab lus rau Diaphragm Wrinkling
Cov kev daws teeb meem feem ntau sib qhia ua rau zoo sib xws, suav nrog kev txhim kho cov khoom tseem ceeb ntawm cov diaphragm thiab ua kom zoo nkauj, kub, thiab sau cov txheej txheem.
Optimer electrode impregnation tuaj yeem ua tiav los ntawm kev ncua lub sij hawm impregnation thiab tsim nyog tsa lub sijhawm impregnation (piv txwv li, 45 degree).
Ntxiv rau cov txheej txheem txhim kho, siv coated diaphragms tuaj yeem ua kom tau zoo txo qhov teeb meem ntawm diaphragm wrinkling. Piv txwv li, diaphragms coated ntawm ib sab nrog PVDF tau txhim kho Adhesion tom qab kub nias, tag nrho tshem tawm lossis txo cov pob.
