Abstract
The present invention relates to a method for controlling the density of an amorphous sulfide and, more specifically, to a method for producing an amorphous sulfide having high ionic conductivity of lithium ions by controlling the interplanar distance between a metal atom and a chalcogen atom through the adjustment of the reaction temperature and rate, in carrying out a sulfidation reaction by supplying a sulfur source in a gas phase onto the surface of a metal or an alloy.
Claims7
A method of preparing an amorphous sulfide exhibiting excellent ionic conductivity, the method comprising:
- preparing a metal or an alloy comprising the metal;
- gas-phase supplying a sulfur source to a surface of the metal or the alloy;
- and
- controlling a reaction rate by adjusting a reaction temperature between the sulfur source and the metal or the alloy −50° C. to 400° C., such that a density of the amorphous sulfide is adjusted,
- wherein the higher the reaction rate is, the lower the density of the amorphous sulfide is.
