However, LIB technologies still lack of safety problem because utilization of liquid electrolytes may drive to explosion at high temperature. Thus, development of solid electrolytes based on lithium aluminium titanate phosphate (LATP) have attracted a lot of attention because they are safer than liquid electrolytes. However, utilization of LATP as solid electrolytes in LIB still limited because of their conductivity is lower than liquid electrolytes. Porous LATP are expected to solve this low conductivity problem by increasing their surface area and their ability to deliver ion. In this research, porous LATP were synthesized using sol gel method and chitosan as template. Concentration of chitosan were varied from 0.0-2.0% w/v to know the influence of chitosan to morphology and properties of obtained LATP. Based on X-ray Diffraction (XRD), all of samples contained LiTi2(PO4)3 (JCPDS PDF 35-0754) and AlPO4 (JCPDS PDF 11-0500), which are part of LATP. Based on Brunauer-Ernett-Teller (BET), Scanning Electron Microscope (SEM), and Electron Impedance Spectroscopy (EIS) analysis, 0.5% w/v chitosan concentration is the optimum condition to obtain the highest surface area (10.7 m2/g) and ionic conductivity (2.2×10-7 S/cm).[/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]Aluminium titanate,Chitosan concentration,Energy storage technologies,High energy densities,Impedance spectroscopy,Liquid electrolytes,Optimum conditions,porous LATP[/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]Chitosan,lithium-ion battery,porous LATP,sol gel method,solid electrolytes[/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]This research was funded by Metal Industry Development Center (B4T), Indonesian ministry of Industry.
