Abstract: Solid electrolyte Li1+xAlxTi2-x(PO4)3(x=0~0.4) was prepared using CH3COOLi·2H2O,Al(NO3)3·9H2O,(NH4)H2PO4,Ti(OC4H9)4 as raw materials by sol-gel technique.The test results show that Li1+xAlxTi2-x(PO4)3 prepared by sol-gel has better cystallintiy.Crystallinity and structure have little difference between the powder and sintered pellet.The ionic conductivity increases first and then decreases with the increase of Al3+ content.When doping amount is 0.3,the ionic conductivity is higher.The change of activation energy is contrary to that of the ionic conductivity.

Key words: sol-gel, solid state electrolyte, A C. impedance, ionic conductivity
