Kev faib tawm thiab qhov zoo ntawm cov ntawv ci tooj liab
Classification ntawm tooj liab ntawv ci
Cov ntawv ci tooj liab feem ntau tuaj yeem muab faib ua ob pawg: dov tooj liab ntawv ci (RA tooj liab ntawv ci) thiab electrolytic tooj liab ntawv ci (ED tooj liab ntawv ci). Ntawm lawv, dov tooj liab ntawv ci muaj qhov zoo ductility thiab lwm yam ntxwv, thiab yog cov tooj liab siv nyob rau hauv cov txheej txheem muag muag muag thaum ntxov. Ntawv ci, thaum electrolytic tooj liab ntawv ci muaj qhov zoo ntawm cov nqi tsim khoom qis dua li cov ntawv ci tooj liab.
(1) Rolled tooj liab ntawv ci
Rolled tooj liab ntawv ci yog ib daim ntawv nyoos (tseem hu ua cov ntawv ntxhib) ua los ntawm dov lub phaj tooj liab ntau zaus, thiab yog roughened raws li qhov yuav tsum tau ua.
Vim qhov kev siv thev naus laus zis ntawm dov tooj liab ntawv ci, nws qhov dav yog qhov nyuaj kom ua tau raws li qhov yuav tsum tau ua ntawm cov tooj liab clad laminates, yog li dov tooj liab ntawv ci tsis tshua muaj siv rau cov tooj liab clad laminates. Txij li thaum lub folding kuj thiab elasticity coefficient ntawm dov tooj liab ntawv ci yog ntau dua li cov electrolytic tooj liab ntawv ci, nws yog haum rau saj zawg zog tooj liab clad laminates.
Cov tooj liab purity ntawm dov tooj liab ntawv ci (99.9%) yog siab dua li ntawm electrolytic tooj liab ntawv ci (99.8%), thiab qhov ntxhib saum npoo yog smoother dua li ntawm electrolytic tooj liab ntawv ci. Cov no yog tag nrho cov conducive rau kev xa xov hluav taws xob sai sai. Yog li ntawd, nyob rau hauv xyoo tas los no, cov teb chaws txawv teb chaws tau siv dov tooj liab ntawv ci los ua cov khoom siv rau cov khoom siv hluav taws xob thiab cov teeb liab ceev ceev thiab cov hlau luam ntawv zoo.
Nws yog siv los ua cov ntaub ntawv luam tawm hauv cov khoom siv suab thiab tuaj yeem txhim kho lub suab zoo. Nws kuj yog siv rau hauv "hlau sandwich boards" ua los txo cov thermal expansion coefficient (TCE) ntawm ntau txheej Circuit Court boards nrog nyias nyob ntawm tej thiab high-layer suav.
(2) Electrolytic tooj liab ntawv ci
Electrolytic tooj liab ntawv ci yog tsim los ntawm thawj dissolving tooj liab rau hauv ib qho kev daws teeb meem, thiab tom qab ntawd electrodepositing tooj liab sulfate electrolyte nyob rau hauv qhov kev txiav txim ntawm ncaj qha tam sim no nyob rau hauv ib tug tshwj xeeb electrolytic khoom los ua tus thawj foil. Cov ntawv ci qub yog tom qab ntawd kho qhov chaw thiab tiv taus corrosion raws li qhov xav tau. Cov txheej txheem ntawm kev kho deg xws li kev kho thermal txheej thiab kev kho oxidation.
Electrolytic tooj liab ntawv ci yog txawv ntawm dov tooj liab ntawv ci. Cov ntaub ntawv crystal deg ntawm electrolytic tooj liab ntawv ntawm ob sab yog txawv. Sab ze ntawm lub cathode roller yog tus du thiab hu ua tus du; sab sab muaj ib tug concave thiab convex siv lead ua qauv thiab yog kuj ntxhib, hu ua matte sab.
Txij li thaum electrolytic tooj liab ntawv ci muaj ib tug columnar siv lead ua qauv thiab nws lub zog, toughness thiab lwm yam khoom yog inferior rau cov dov tooj liab ntawv ci, electrolytic tooj liab ntawv ci feem ntau yog siv nyob rau hauv zus tau tej cov tooj liab-clad laminates thiab ces ua nyob rau hauv nruj boards.
Kev ua tau zoo ntawm carbon-coated tooj liab ntawv ci
1. Txhim kho qhov sib xws ntawm kev siv roj teeb pob thiab txo cov nqi roj teeb kom zoo.
Qhov tseem ceeb txo qhov nce hauv dynamic internal kuj ntawm lub roj teeb ntawm tes;
Txhim kho qhov sib txawv ntawm qhov sib txawv ntawm lub roj teeb pob;
Txuas lub roj teeb lub neej.
2. Txhim kho qhov kev sib txuas ntawm cov khoom siv thiab cov khoom siv tam sim no thiab txo cov nqi tsim khoom ntawm cov ncej. zoo li:
Txhim kho qhov adhesion ntawm cov khoom siv cathode thiab cov khoom siv los ntawm cov khoom siv dej;
Txhim kho qhov adhesion ntawm nanoscale lossis submicron cathode cov ntaub ntawv thiab cov khoom sau;
Txhim kho qhov adhesion ntawm lithium titanate lossis lwm yam khoom muaj peev xwm anode thiab cov khoom sau;
Txhim kho tus ncej ncej tsim tsim nyog tus nqi thiab txo tus ncej ncej tsim cov nqi.
3. Txo polarization, nce tus nqi thiab gram muaj peev xwm, thiab txhim kho roj teeb kev ua tau zoo. zoo li:
Ib nrab txo qhov kev faib ua feem ntawm binder nyob rau hauv cov khoom nquag thiab ua kom muaj peev xwm ntawm gram;
Txhim kho hluav taws xob sib cuag ntawm cov khoom siv thiab cov khoom siv tam sim no;
Txo polarization thiab txhim kho lub zog ua haujlwm.
4. Tiv thaiv cov khoom siv tam sim no thiab txuas ntxiv roj teeb lub neej. zoo li:
Tiv thaiv cov khoom siv corrosion thiab oxidation;
Txhim kho qhov nro ntawm cov khoom siv thiab txhim kho cov txheej txheem yooj yim ntawm cov khoom siv;
tuaj yeem hloov cov ntawv etched kim dua lossis hloov cov ntawv foils nrog cov ntawv nyias nyias.
