Ini additioni toi thei cathodei andi anode,i componenti thati alsoi affecti thei sodium-ioni batteryi performancei isi thei separator.i Thei separatori hasi ani importanti rolei asi ai pathwayi fori rapidi movementi ofi ionici chargei fromi cathodei toi anodei andi vicei versa.i Thei separatori alsoi functionsi asi ai separatori betweeni thei cathodei andi anodei toi preventi internali shorti circuit.i Materialsi commonlyi usedi asi separatori materialsi arei stilli dominatedi byi thei polyolefini polymeri materiali group,i namelyi polypropylenei andi polyethylenei becausei theyi havei highi electrochemicali resistancei properties.i However,i thei lowi thermali resistancei andi wettabilityi propertiesi ofi polyolefinsi cani decreasei thei performancei ofi sodium-ioni battery.i Cellulosei isi ani alternativei materiali toi replacei polyolefini becausei ofi itsi abundance,i biodegradable,i highi thermali andi chemicali resistance,i andi goodi wettabilityi properties.i Thisi researchi focusesi oni thei synthesisi andi characterizationi ofi cellulosei fromi sugarcanei bagassei asi sodium-ioni batteryi separator.i Sugarcanei bagassei asi ai sourcei ofi cellulosei isi usedi becausei iti containsi ai loti ofi cellulosei comparedi toi anotheri biomass.i Isolationi ofi cellulosei wasi carriedi outi usingi alkalizationi methodsi withi NaOHi solution,i bleaching,i andi hydrolysisi withi H2SO4i solution.i Theni thei cellulosei wasi madei intoi ai batteryi separatori usingi thei papermakingi methodi andi testedi fori FTIR,i TEM,i SEM,i wettability,i tensilei strength,i andi dimensionali stabilityi ati variousi temperatures.i Fromi thei characterizationi ofi thei membranei ini thisi research,i iti wasi foundi thati ai porousi membranei hadi betteri wettabilityi propertiesi andi thermali resistancei thani thei commerciallyi usedi batteryi separator,i celgard.i However,i thei leveli ofi fiberi densityi formed,i andi thei tensilei resistancei ofi thei resultingi membranei isi worsei thani celgard.i Thesei resultsi indicatei thati sugarcanei bagassei cellulosei cani bei usedi asi ani alternativei asi ai polyolefini substitutei fori sodium-ioni batteryi separatorsi withi furtheri optimizationi ofi thei synthesisi process.
