Abstract

본발명은 양극활물질, 제 1 LLZO, 제 1전도성 고분자, 제 1리튬염 및 도전재를 포함하는 양극;리튬 금속을 포함하는 음극; 및 양극과 음극사이에, 제 2 LLZO, 제 2 전도성 고분자 및 제 2 리튬염을 포함하는 복합고체전해질층;을 포함하고, 제 1및 제 2 LLZO는 각각 독립적으로 알루미늄이 도핑 또는 비도핑된 LLZO인 전고체 리튬이차전지가 제공된다. 본 발명의 전고체리튬이차전지는 양극과 복합고체전해질층에 동시에 전도성 고분자, 리튬염 및 무기계 세라믹 고체전해질을 포함하여 전지의 방전용량 및 싸이클 특성이 향상될 수 있다. 또한, 본 발명의 전고체 리튬이차전지의 제조방법은 양극과 복합고체전해질층에 동시에 전도성 고분자, 리튬염 및 무기계 세라믹 고체전해질을 포함시켜 비소결 방식으로 전고체 리륨이차전지를 제조함으로써 제조비용을 감소시키고, 활물질 /활물질간,고체전해질 입자 간, 전해질 /전극 간의 계면반응을 제어하여 전지의 내부저항을 보다 감소시킬 수 있다.
