Synthesis and Characterization of Li₄Ti₅O₁₂ Doped by Na and Al as Anodes Material for Li-Ion Batteries

Abstract:

Li₄Ti₅O₁₂ pure and Li₄Ti₅O₁₂ with Na and Al doped Li_(3-x/3)Al_xNaTi_(5-2x/3)O₁₂ (x=0, 0.025, 0.05, 0.075) as anodes for Li-ion batteries are synthesized at 850°C via solid state reaction using Li₂CO₃, TiO₂-anatase, Al₂O₃ and Na₂CO₃ as precursor. The effect of substitution of Al and Na in Li₄Ti₅O₁₂ on characterization of precursor and electrochemical performance is studied. It is found that Na doped in Li₄Ti₅O₁₂ pure affected the formation of three phase i.e NaLiTi₃O₇, Li₄Ti₅O₁₂, dan Li₂TiO₃. Meanwhile, Al doped contributed to the formation of NaLiTi₃O₇ phase significantly. The SEM images show that the particles have polyhedral shape with uniform size distribution. Na doped in the Li₄Ti₅O₁₂affected particle size become larger against Al doped particle size become smaller than undoped material, the best particle size measured by PSA is 30,89 . All characterization of material will determine the electrochemical performance of Li-ion battery.
