Abstract

Porous Lithium Titanate (Li ₄ Ti ₅ O ₁₂ ) is one of attractive materials for safer and more stable anode of lithium-ion batteries with improved ionic conductivity. In this study, porous Li ₄ Ti ₅ O ₁₂ were synthesized by sol-gel method using eggshell membrane as soft template. X-Ray Diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) results indicated that Li ₄ Ti ₅ O ₁₂ were successfully formed. Scanning Electron Microscope (SEM), Brunauer-Emmett-Teller (BET) and Electrochemical Impedance Spectroscopy (EIS) results showed that porous Li ₄ Ti ₅ O ₁₂ with highest surface area (23.1 ±0.4 m ² 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.
