Nanometer sized cellulose is known as nanocrystalline has a higher surface area than cellulose. Due to this property, it is more easily to be modified for various applications such as for reinforcing agent in lithium ion battery separator. Nanocrystalline cellulose was obtained by acid hydrolysis of cellulose. The cellulose used in this study was obtained by isolation of corncob, followed by hydrolyzed using H2SO4 50% at 45°C for 60 minutes. Nanocrystalline cellulose was then characterized by FT-IR spectroscopy, Particle Size Analyzer (PSA), Scanning Electron Microscope (SEM) and X-Ray diffraction. Based on PSA results, the nanocrystalline cellulose has an average diameter of 17,4 nm with a spherical morphology determined by SEM analysis. The analysis of X-Ray diffraction showed the crystallinity index of nanocrystalline cellulose was higher than isolated cellulose in the amount of 75%. The Impedance Spectrometry (IE) measurement showed that the ionic conductivity of PVA/LiClO4/nanocrystalline cellulose membrane is 1.66 × 10-4 S/cm. So, nanocrystalline cellulose has a potential to be used as a nanocomposite in polymer electrolyte membranes for lithium ion battery separator.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acid hydrolysis,corncob,Impedance spectrometry,Lithium ions,Nanocrystalline cellulose,Particle size analyzers,Polymer electrolyte membranes,Spherical morphologies[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]acid hydrolysis,corncob,lithium ion battery separator,nanocrystalline cellulose[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICEVTIMECE.2015.7496689[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
