Abstract
Li ion conductive sulfide glass, can be made by providing a pre-mix of precursor materials for making the Li ion conductive sulfide glass, providing a melting tank for processing the pre-mix to a molten state, and heating the melting tank to a temperature that is sufficient to melt form the Li ion conductive sulfide glass, wherein the melting tank is a metal vessel having inner wall surfaces that are coated with a corrosion resistant metal oxide layer.
Claims10
A method of making Li ion conductive sulfide glass, the method comprising:
- i) providing a pre-mix of precursor materials for making the Li ion conductive sulfide glass;
- ii) providing a melting tank for processing the pre-mix to a molten state;
- and
- iii) heating the melting tank to a temperature that is sufficient to melt form the Li ion conductive sulfide glass;

A method of making thin Li ion conductive glass sheet, the method comprising:
- i) providing a draw tower for making thin glass sheet, the draw tower comprising a draw apparatus that interfaces with a melting tank to allow Li ion conductive sulfide glass to flow from the melting tank to the draw apparatus;
- ii) loading the melting tank with a pre-mix of precursor materials for making the Li ion conductive sulfide glass;
- iii) heating the melting tank to a temperature that is sufficient to melt process the pre-mix to a molten Li ion conductive sulfide glass;
- iii) maintaining the melting tank at a temperature sufficient to allow the glass to flow;
- iv) flowing the glass into the draw apparatus for making thin conductive glass sheet.
A method of making Li ion conductive sulfide glass, the method comprising:
- i) providing a pre-mix of precursor materials for making the Li ion conductive sulfide glass;
- ii) providing a primary vessel for processing the pre-mix to a molten state, wherein the primary vessel has an inner metal sealing layer, wherein the metal of the sealing layer is corrosion resistant and has a melting temperature above the processing temperature of the glass.
A method of making Li ion conductive sulfide glass, the method comprising:
- i) providing a vessel system comprising a primary vessel and an interior secondary vessel, wherein the secondary vessel is vitreous carbon;
- ii) loading the secondary vessel with a pre-mix of precursor materials for making Li ion conductive sulfide glass;
- and
- iii) heating the vessel system to a temperature sufficient to melt form the Li-ion conductive sulfur glass.
