Abstract

본 발명은 2이상의 금속전구체를 고분자와 함께 전기 방사한 후 열처리하여 나노 응집체 또는 나노 입자 형태의 다성분계 나노 복합산화물 분말을 얻을 수 있으며, 얻어진 나노 복합산화물 분말을 음극 및 양극의 전극활물질로 사용하면 저렴한 비용으로 전극 및 박막전지의 대량생산이 이루어질 수 있는 다성분계 나노 복합산화물 분말의 제조방법, 이를 이용한 전극의 제조방법과 이를 이용한 박막 전지 및 그 제조방법에 관한 것이다. 본 발명의 다성분계 나노 복합산화물 분말의 제조방법은 2이상의 금속전구체를 섬유 성형성 고분자 및 용매와 혼합하여 방사용액을 준비하는 단계와; 상기 방사용액을 전기방사하여 금속전구체가 탑재된 고분자 나노 복합섬유를 형성하는 단계와; 상기 나노 복합섬유를 산화분위기에서 열처리하여 고분자를 제거함에 의해 다성분계 나노 복합산화물 입자 섬유로 변환하는 단계와; 상기 얻어진 나노 복합산화물 섬유를 분쇄하여 다성분계 나노 복합산화물 분말을 형성하는 단계를 포함하는 것을 특징으로 한다.
