Abstract

본 발명은 전도성 직물로 형성된 보호층을 포함하는 리튬 이차전지용 음극에 관한 것으로, 보다 상세하게는 상기 리튬 금속층의 적어도 일면 상에 형성되며 공극을 가지는 전도성 직물을 포함하는 리튬 이차전지용 음극 및 이를 포함하는 리튬 이차전지에 관한 것이다. 본 발명에 따른 전도성 직물을 보호층으로 가지는 음극을 적용한 리튬 이차전지는 리튬 금속의 석출 및 제거 반응을 상기 보호층의 공극 내부에서 유도하여, 리튬 금속 표면상에 리튬 금속의 국소적인 형성을 방지하여 덴드라이트 형성을 억제하고 균일한 표면을 형성하게 하며, 이로 인해 셀의 부피팽창을 억제할 수 있다. 뿐만 아니라 전도성 직물의 유연성 및 인장/수축으로 인하여 리튬 금속의 석출 및 제거 반응이 발생되어도 기계적 안정성을 유지할 수 있다.
