In this study, porous Li4Ti5O12 were synthesized by sol-gel method using eggshell membrane as soft template. X-Ray Diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) results indicated that Li4Ti5O12 were successfully formed. Scanning Electron Microscope (SEM), Brunauer-Emmett-Teller (BET) and Electrochemical Impedance Spectroscopy (EIS) results showed that porous Li4Ti5O12 with highest surface area (23.1 ±0.4 m2 g-1) and highest ionic conductivity (7.2 ±0.3 ×10-10 S cm-1) could be obtained by preparing sample in the presence of eggshell membrane, using lower precursor concentration (0.025 M) and calcination temperature at 850 °C.[/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]Brunauer emmett tellers,Calcination temperature,Egg shell membranes,Energy dispersive spectroscopies (EDS),Li4Ti5O12,Lithium titanate,Precursor concentration,Soft template[/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]egg shell membrane,ionic conductivity,lithium-ion batteries,porous Li4Ti5O12,soft template[/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/10.1088/2053-1591/ab1298[/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]
