摘要：

The effect of calcination on Li ion conductivity of Li1.5Al0.5Ge1.5(PO4)(3) (LAGP) solid electrolyte prepared by a sol gel method is examined. The Li ion conductivity of LAGP increases with calcination temperature. After reaching maximum conductivity at 850 degrees C, the conductivity decreases with increase of the calcination temperature. The calcination holding time also strongly affects Li ion conductivity of LAGP. The conductivity increases with holding time until 12 h and then decreases. It is found that the control of crystallization rate is critical to obtain bulk LAGP with high Li ion conductivity. The highest bulk and total conductivities at 30 degrees C are 9.5 x 10(-4) and 1.8 x 10(-4) S cm(-1), respectively, obtained for the bulk LAGP calcined at 850 degrees C for 12 h.
