Abstract
An apparatus for producing lithium sulfide, including: a reaction container for allowing lithium hydroxide powder to be in contact with a hydrogen sulfide gas; a stirring blade inside the reaction container; a first heating apparatus that keeps the temperature of an inner wall of the reaction container that is in contact with the powder; and a second heating apparatus that keeps the temperature of an inner wall that is not in contact with the powder.
Claims17
An apparatus for producing lithium sulfide, comprising:
- a reaction container for allowing lithium hydroxide powder to be in contact with a hydrogen sulfide gas;
- a stirring blade inside the reaction container;
- a first heating apparatus that keeps a temperature of an inner wall of the reaction container that is in contact with the lithium hydroxide powder;
- and
- a second heating apparatus that keeps a temperature of an inner wall of the reaction container that is not in contact with the lithium hydroxide powder,
- wherein a capacity of the reaction container is 0.1 liter or more and 100 kiloliters or less.
3 more elements
A method for producing lithium sulfide, the method comprising:
- incorporating lithium hydroxide into a reaction container in an amount of 0.1 kg or more relative to 1 liter of a capacity of the reaction container,
- introducing hydrogen sulfide to the reaction container at a flow rate of 5 liters;
- min or less relative to 1 kg of the lithium hydroxide, and
- reacting the lithium hydroxide with the hydrogen sulfide while stirring the lithium hydroxide so as not to allow it to be stagnated,
- wherein the method is performed in an absence of a solvent.
