description	The present invention relates to a method for producing high-purity lithium sulfide through wet and dry processes and, more specifically, to a lithium sulfide production method capable of mass-producing high-purity lithium sulfide through: a dry process of reacting lithium hydroxide (LiOH) with hydrogen sulfide (H2S) gas in an organic solvent; and a dry process of reacting a dry product obtained therefrom with hydrogen sulfide (H2S) gas. La présente invention concerne une méthode de production de sulfure de lithium de haute pureté par des procédés humides et secs et, plus spécifiquement, une méthode de production de sulfure de lithium capable de produire en masse du sulfure de lithium de haute pureté par : un procédé sec de réaction d'hydroxyde de lithium (LiOH) avec du sulfure d'hydrogène (H2S) gazeux dans un solvant organique ; et un procédé sec de réaction d'un produit sec obtenu à partir de celui-ci avec du sulfure d'hydrogène (H2S) gazeux. 본 발명은 습식 및 건식 공정을 통한 고순도 황화리튬의 제조방법에 관한 것으로, 상세하게는 수산화리튬(LiOH)을 유기용매 하에서 황화수소(H2S) 기체와 반응시키는 습식 공정과, 이로부터 수득된 건조 수득물을 황화수소(H2S) 기체와 반응시키는 건식 공정을 통해 고순도의 황화리튬을 대량으로 생산할 수 있는 황화리튬의 제조방법을 제공한다.
