수열합성을 통해 합성한 다공성 NiO는 리튬 폴리설파이드의 용출을 억제하기 위하여 리튬-황 전지의 전극에 사용되었다. 리튬-황 전지의 전극은 경제적이고 간단한 진공 여과 방법을 이용하여 집전체와 바인더가 없는 프리스탠딩 플렉서블 전극으로 제작되었다. 다공성 NiO를 첨가한 S/CNT/NiO 전극은 순수 S/CNT 전극에 비해 125 mA h g^-1 증가한 877 mA h g^-1 (0.2 C)의 초기 방전용량과 200 사이클 후 84% (S/CNT: 66%)의 우수한 용량 유지율을 나타내었다. 이는 방전 과정 중에서 NiO와 리튬 폴리설파이드의 강한 화학적 결합에 의하여 리튬 폴리설파이드의 전해질로 용출되는 것을 억제하여 나타난 결과이다. 또한 S/CNT/NiO 전극의 유연성 테스트를 위해 1.6 × 4 cm²의 파우치셀로 제작하여 폴딩한 상태와 하지 않은 상태에서 모두 620 mA h g^-1의 안정적인 사이클 특성을 나타내었다.

Abstract ▼ AI-Helper

Porous NiO synthesized via hydrothermal synthesis was used in the electrodes of lithium-sulfur batteries to inhibit the elution of lithium polysulfide. The electrode of the lithium-sulfur battery was manufactured as a freestanding flexible electrode using an economical and simple vacuum filtration method without a current collector and a binder. The porous NiO-added S/CNT/NiO electrode exhibited a high initial discharge capacity of 877 mA h g-1 (0.2 C), which was 125 mA h g-1 higher than that of S/CNT, and also showed excellent retention of 84% (S/CNT: 66%). This is the result of suppressing the dissolution of lithium polysulfide into the electrolyte by the strong chemical bond between NiO and lithium polysulfide during the charging and discharging process. In addition, for the flexibility test of the S/CNT/NiO electrode, the 1.6 × 4 cm2 pouch cell was prepared and exhibited stable cycle characteristics of 620 mA h g-1 in both the unfolded and folded state.
