New Lithium Fast Ion Conductors of Li1+2x+yAlxYbyTi2-x-ySixP3-xO12 System
摘要
Abstract
Refined natural kaolinite was used as a starting material for preparing new lithium fast ion conductors of Li1+2x+yAlxYbyTi2-x-ySixP3-xO12 system by high temperature (9501150C) solid phase reaction for about 20h. The syntheses temperatures are lowered with increasing the value of x and y for the system. The X-ray powder diffraction shows that a Lisicon phase with R3c space group exists in the composition range of y=0.3, x0.4 and y=0.5, x0.3. The initial composition with y=0.3, x=0.1 possesses a maximum ionic conductivity of 2.4510-2S/cm at 673K and its activation energy is 38.3kJ/mol in the temperature range of 473673K.关键词
