| Zusammenfassung: | The present invention relates to a positive electrode for a lithium secondary battery, comprising sulfur-halloysite complex which can improve the capacity and energy amount of the battery by replacing the conventional sulfur-carbon composite being applied as a positive electrode active material with a sulfur-clay complex and increasing the sulfur content in the positive electrode, to a production method thereof, and to a lithium secondary battery comprising the positive electrode. The positive electrode for a lithium secondary battery comprises the sulfur-halloysite complex including: halloysite, a kaolin-based clay; and sulfur supported on the halloysite.
양극 활물질로 적용 중인 통상의 황-탄소 복합체를 황-점토 복합체로 대체하고, 양극 내 황의 함량을 높임으로써 전지의 용량 및 에너지량을 향상시킬 수 있는, 황-할로이사이트 복합체를 포함하는 리튬 이차전지용 양극, 그 제조방법 및 상기 양극을 포함하는 리튬 이차전지가 개시된다. 상기 리튬 이차전지용 양극은, 고령토계 점토인 할로이사이트; 및 상기 할로이사이트에 담지된 황;을 포함하는 황-할로이사이트 복합체를 포함한다. |
