Abstract
Official abstract text for this publication.
A method for producing complexed particles, wherein the method comprises: obtaining a good solvent solution, by dissolving Li 2 S, and LiX (X is at least one selected from a group consisting of F, Cl, Br, and I) in a good solvent, and precipitating particles by contacting the good solvent solution with a poor solvent having a temperature at least 165° C. higher than the boiling point of the good solvent, to evaporate off the good solvent; and, wherein the method satisfies at least one of the following: (i) the good solvent solution being obtained by further dissolving H 2 S in the good solvent, and (ii) H 2 S being dissolved in the poor solvent.
First claim

1 . A method for producing complexed particles, wherein the method comprises: obtaining a good solvent solution, by dissolving Li 2 S, and LiX (X is at least one selected from a group consisting of F, Cl, Br, and I) in a good solvent, and precipitating particles by contacting the good solvent solution with a poor solvent having a temperature at least 165° C. higher than the boiling point of the good solvent, to evaporate off the good solvent; and, wherein the method satisfies at least one of the following: (i) the good solvent solution being obtained by further dissolving H 2 S in the good solvent, and (ii) H 2 S being dissolved in the poor solvent. 2 . The method according to claim 1 , wherein the LiX is LiI and LiBr. 3 . The method according to claim 1 , wherein at least the (i) is satisfied. 4 . The method according to claim 3 , wherein in the (i), the good solvent solution is obtained by further dissolving H 2 S in the good solvent by blowing H 2 S into the good solvent. 5 . The method according to claim 1 , wherein at least the (ii) is satisfied. 6 . The method according to claim 5 , wherein in the (ii), the H 2 S is dissolved in the poor solvent by blowing H 2 S into the poor solvent. 7 . The method according to claim 1 , wherein the ratio of the LiX (X is at least one selected from a group consisting of F, Cl, Br, and I) is 0.30 mol to 0.60 mol based on 1 mol of Li 2 S. 8 . A method for producing complexed particles, wherein the method comprises: obtaining a good solvent solution, by dissolving LiHS, and LiX (X is at least one selected from a group consisting of F, Cl, Br, and I) in a good solvent, and precipitating particles by contacting the good solvent solution with a poor solvent having a temperature at least 165° C. higher than the boiling point of the good solvent to evaporate off the good solvent. 9 . The method according to claim 8 , wherein the ratio of the LiX (X is at least one selected from a group consisting of F, Cl, Br, and I) is 0.30 mol to 0.60 mol based on 1 mol of LiS. 10 . The method according to claim 8 , wherein the LiX is LiI and LiBr. 11 . The method according to claim 1 , wherein the contacting the good solvent solution with the poor solvent is by dropping, spraying, or injecting the good solvent solution into the poor solvent. 12 . The method according to claim 11 , wherein the contacting the good solvent solution with the poor solvent is by dropping the good solvent solution into the poor solvent.
