Thaum muas carbon-coated tooj liab ntawv ci los yog carbon-coated aluminium ntawv ci rau lithium-ion roj teeb, ib qho ntawm cov lus nug ntau tshaj plaws los ntawm cov tuam txhab roj teeb yog:
Kuv puas yuav tsum xaiv tus primer dej los yog NMP-based primer rau kuv lub roj teeb?
Qhov no yog ib lo lus nug tseem ceeb vim hais tias cov primer tsis yog tsuas yog ib tug conductive txheej ntawm cov hlau tam sim no collector thiab cov khoom siv electrode. Nws kuj plays lub luag hauj lwm nyob rau hauv interfacial adhesion, hluav taws xob kev sib cuag, tshuaj tiv thaiv, thiab manufacturing stability.
Xaiv cov primer tsis haum yuav ua rau tsis zoo adhesion, txheej delamination, nce kev tiv thaiv, corrosion, los yog puas thaum lub sij hawm tom ntej electrode processing.Txawm li cas los xij, tsis muaj universal teb raws li roj teeb chemistry ib leeg.
Piv txwv li, LFP cathodes tsis tas yuav tsum muaj tib lub primer formulation nyob rau hauv txhua kab ntau lawm. Qhov kev xaiv tsim nyog yog nyob ntawm seb cov electrode slurry siv PVDF / NMP, CMC / SBR / dej, los yog lwm yam binder thiab hnyav system.
Hauv phau ntawv qhia no, peb piav qhia qhov sib txawv ntawm cov dej-raws li thiab NMP-based primers, yuav ua li cas xaiv cov primer zoo rau carbon-coated copper foil thiab carbon-coated aluminium foil, thiab cov tuam txhab roj teeb dab tsi yuav tsum ntsuas ua ntej muab qhov kev txiav txim.
