METHOD OF MANUFACTURING LITHIUM ION CONDUCTIVE GLASS CERAMIC

摘要

A method of manufacturing a lithium ion conductive glass ceramic, includes a step of forming granules using a material including an SiO2 source, a ZrO2 source, a P2O5 source and an Na2O source; a step of obtaining a powder including a glass ceramic by passing the granules under a heated gas phase atmosphere to melt the granules and solidifying the melted granules; a step of obtaining a target object including a glass ceramic by performing a heat treatment on the powder to precipitate crystals; and a step of obtaining a lithium ion conductive glass ceramic by performing an ion-exchange process on the target object in molten salt including lithium ions.

1. A method of manufacturing a lithium ion conductive glass ceramic, comprising:
a step (a) of forming granules using a material including an SiO2 source, a ZrO2 source, a P2O5 source and an Na2O source; a step (b) of obtaining a powder that becomes a target object including a glass ceramic by passing the granules under a heated gas phase atmosphere to melt the granules, solidifying the melted granules and precipitating crystals while the melted granules are being solidified, the powder including, in terms of oxides, 20 mol % to 60 mol % of SiO2, 5 mol % to 45 mol % of ZrO2, 3 mol % to 30 mol % of P2O5 and 15 mol % to 45 mol % of Na2O; and a step (d) of obtaining a lithium ion conductive glass ceramic by performing an ion-exchange process on the target object in molten salt including lithium ions.
