Abstract

본 발명은 비정질상 음극활물질 및 이를 이용한 전극의 제조방법 및 이를 포함하는 이차전지 및 하이브리드 커패시터에 관한 것으로서, 본 발명에 의한 비정질상 음극활물질은, 금속산화물 또는 금속인산화물 중 적어도 하나를 포함하여 이루어지며, 상기 금속산화물과 상기 금속인산화물은 비정질상인 것을 특징으로 한다. 상기 금속산화물은 MOX (0 < X ≤ 3)의 형태로 이루어지며, 상기 M은 몰리브덴(Mo), 바나듐(V), 스칸듐(Sc), 티타늄(Ti), 크롬(Cr), 이트륨(Y), 지르코늄(Zr), 니오브(Nb), 텅스텐(W) 중 적어도 하나인 것을 특징으로 하며, 상기 금속인산화물은 AxBy(PO4) (0 ≤ x ≤ 2, 0 < y ≤ 2)의 형태로 이루어지며, 상기 A는 리튬(Li), 나트륨(Na), 칼륨(K) 중 적어도 하나이고, 상기 B는 몰리브덴(Mo), 바나듐(V), 스칸듐(Sc), 티타늄(Ti), 크롬(Cr), 이트륨(Y), 지르코늄(Zr), 니오브(Nb), 텅스텐(W) 중 적어도 하나인 것을 특징으로 한다. 본 발명에 의하면, 비정질상인 금속의 산화물 및 인산화물을 음극활물질로 사용함으로써, 리튬, 소디움 등의 저장장소와 이들 이온의 확산속도를 증대시켜 전지의 용량과 속도특성을 크게 향상시킬 수 있는 장점이 있으며, 직선에 가까운 기울기를 갖는 충 방전 전압곡선을 보이고 있기 때문에 완전지의 충전과 방전 상태를 추적하거나 예측하기에 용이하며, 여기에 더하여 우수한 싸이클 수명을 보이고 있기 때문에, 리튬 이차전지, 소디움 이차전지, 하이브리드 커패시터의 음극으로 상용화 가능성이 매우 클 것으로 예상된다.
