More Information
Summary:The present invention relates to an electrode and a lithium secondary battery comprising the same, and more specifically, to an electrode which comprises the following: an electrode layer; a pre-lithiation preventing layer formed on the electrode layer; and a lithium layer formed on the pre-lithiation preventing layer, thereby blocking the fire caused by the lithiation reaction due to the contact between lithium and silicon before assembling a cell, while greatly reducing the irreversible capacity reduction problem of a negative electrode. 본 발명은 전극 및 이를 포함하는 리튬 이차 전지에 관한 것으로, 더욱 상세하게는 전극층; 상기 전극층 상에 형성된 전리튬화 방지층; 및 상기 전리튬화 방지층 상에 형성되는 리튬층을 포함하여 셀 조립 전 리튬과 실리콘의 접촉에 의한 리튬화 반응에 의한 화재를 차단함과 동시에, 음극의 비가역 용량 저하 문제를 크게 개선할 수 있는 전극 및 이를 포함하는 리튬 이차 전지에 관한 것이다.
