초록

나노 탄소재료를 복합화하면 기존 재료의 특성을 유지하면서 그 효율을 극대화할 수 있다. 여기에 이종원소를 부가하면 전기화학적인 특성이 디자인되므로, 나노 탄소재료의 복합화를 통해 한 종류의 나노 재료로부터 여러 강점을 얻을 수 있다. 특히 탄소나노섬유와 금속산화물을 복합화하면 탄소나노섬유의 전기이중층 뿐만 아니라 금속산화물의 산화 환원 반응을 이용하여 비축전 용량, 고율 특성, 수명 특성이 향상되고 높은 수준의 출력밀도가 유지되는 고용량 슈퍼 캐퍼시터용 전극 소재를 개발할 수 있다. 본 총설에서는 탄소의 고출력특성과 금속산화물의 고에너지 특성이 동시에 발현되는 금속산화물계 탄소나노섬유복합체의 제법과 응용에 대한 최신연구를 다루도록 하겠다.

The hybridization of carbon nano-materials enhances the efficiency of each function of the resulting structure or composites. Also, the addition of non-carbon elements to nanomaterials modifies the electrochemical properties. Electrodes combining porous carbon nanofibers (CNFs) and metal oxides benefit from the combination of the double-layer capacitance of the CNFs and the pseudocapacitive character associated with the surface redox-type reactions. Consequently, they demonstrate superior supercapacitor performance in terms of high capacitance, high energy/power efficiency and high rate capability. This paper presents a comprehensive review of the latest advances made in the development and application of various metal oxide/CNF composites (CNFCs) to supercapacitor electrodes.
