Zusammenfassung: | The present invention relates to a lithium-sulfur all-solid battery comprising a graphite sheet interposed between an anode containing sulfur and an anode current collector. The lithium-sulfur all-solid battery according to the present invention inserts a graphite sheet between the electrode and the anode current collector to enable smooth electron transfer between a current collector layer and the anode layer, thereby significantly reducing the volume of the secondary battery while greatly increasing the capacity per volume.
본 발명은 황(sulfur)을 함유하는 양극 및 양극 집전체 사이에 개재(介在)된 흑연 시트(graphite sheet)를 포함하는 리튬-황 전고체전지에 관한 것으로서, 본 발명에 따른 리튬-황 전고체전지는 집전체층과 양극층 간의 원활한 전자이동을 가능케하는 흑연 시트를 전극 및 양극 집전체 사이에 삽입시킴으로써, 이차전지 전체 부피를 현저히 감소시킴과 동시에 부피당 용량을 크게 증가시킬 수 있다. |
