Zusammenfassung:	PURPOSE: Provided is a process for producing a lithium-contained nitride for a lithium secondary battery, which can improve lifetime property and capacity of the lithium secondary battery. CONSTITUTION: The process for producing the lithium-contained nitride comprises the steps of: synthesizing the lithium-contained nitride; sintering the nitride at 600-800deg.C for 6-10 hours; grinding the sintered nitride mechanically by using a ball mill, wherein the ground lithium-contained nitride has an average particle diameter of 1-50 micrometer. 본 발명은 리튬 이차 전지용 리튬함유 질화물의 제조 방법에 관한 것으로서, 상기 방법은 리튬함유 질화물을 합성하는 단계; 상기 질화물을 소결하는 단계; 및 소결된 질화물을 기계적으로 분쇄하는 단계를 포함한다.
