Abstract
The invention provides a process for producing a sulfide-based solid electrolyte, the process having: a raw material composition preparation step for preparing a raw material composition containing at least sulfur (S), an adhesion inhibitor addition step for adding to the raw material composition an adhesion inhibitor that inhibits formation of adhered substances including the unreacted raw material composition, on the inner surface of a milling pot during mechanical milling, and a vitrification step for synthesizing sulfide-based glass by carrying out mechanical milling on the raw material composition to which the adhesion inhibitor has been added.
Claims14
A process for producing a sulfide-based solid electrolyte, comprising:
- preparing a raw material composition containing at least sulfur;
- adding to the raw material composition an adhesion inhibitor that inhibits formation of adhered substances including the unreacted raw material composition on an inner surface of a milling pot during mechanical milling, the adhesion inhibitor being an alkane that is liquid at normal temperature;
- and
- synthesizing sulfide-based glass by carrying out mechanical milling on the raw material composition to which the adhesion inhibitor has been added;
- and
- baking the sulfide-based glass.
