AMORPHOUS LITHIUM IONIC CONDUCTOR B2O3-0.7Li2O-0.7LiCl-xAl2O3
非晶态锂离子导体B2O3-0.7Li2O-0.7LiCl-xAl2O3

The effect of additive Al2O3 on both the formation of amorphous B2O3-0.7Li2O-0.7LiCl and it's ion conduction property have been studied. It has been found that rather large slab of amorphous material could be easily prepared by pouring directly the melt contained suitable amount of additive Al2O3 onto a copper plate at room temperature without using liquid nitrogen.The additive A12O3 decreases slightly the conductivity of amorphous B2O3-0.7Li2O-0.7LiCl but in high temperature range this effect is far less obvious because of the activation energy for the amorphous containing Al2O3 is slightly larger than that of pure one. It has been shown that Al2O3 = 0.03 is the optimum content which makes the preparation of amorphous more easily and dose not seriously influence the conductivity.
