Abstract

PURPOSE:To obtain a superior solid electrolyte for an electrochromic display element by specifying the compositional ratio of the components of an amorphous body of lithium fluoroaluminate so as to increase the ionic conductivity. CONSTITUTION:LiF is mixed with AlF3 in 5:3 molar ratio, and NaF is substituted for part of the LiF. Powder of the resulting mixture is melted by heating, and the melt is spouted from the bottom nozzle of a crucible onto a rotating copper roll under pressure of gaseous Ar. Thus, the melt is formed into a film shape by the rapid cooling or other method to manufacture a solid electrolyte film made of amorphous body represented by the general formula[where (a) is 0.45-0.7, (b) is 0.3-0.55 and (x) is 0.1-1.0). This film has high Li ionic conductivity such as about 1X10<-5> (OMEGAcm)<-1> and is suitable for use as a solid electrolyte for an electrochromic display element, etc.
