PROBLEM TO BE SOLVED : To provide a method for producing a glass-ceramic ion conductor which recycles materials containing rare and expensive starting materials such as rare earths, precious metals or germanium from spent batteries. SOLUTION : The method for producing a glass-ceramic ion conductor, comprises steps of : preparing recycled materials from spent batteries which contain glass-ceramic ion conductors; adding glass raw materials; melting the recycled materials; homogenizing the obtained melt; and molding and ceramicizing a glass. Ion conductors which are similar to conventional glass-ceramic ion conductors (e.g., LiSiCon structure) and particularly suitable as a solid electrolyte are produced by adding recycled components from the spend batteries.
