摘要：

The new crystalline material family, lithium superionic conductor (thio-LISICON), was found in the Li2S-GeS2-P2S5 system. The solid solution member x = 0.75 in Li4-xGe1-xPxS4 shows the highest conductivity of 2.2 x 10(3) S cm(-1) at 25 degreesC of any sintered ceramic, together with negligible electronic conductivity, high electrochemical stability, no reaction with lithium metal, and no phase transition up to 500 degreesC. Its material design concepts of changing constituent ions with various ionic radii. valence, and polarizability are described. (C) 2001 The Electrochemical Society.
