Title:
LITHIUM SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/096331
Kind Code:
A1
Abstract:
The present invention relates to a lithium secondary battery and, more specifically, to a lithium secondary battery comprising a cathode catalyst including a transition metal composite having a stable structure in which four nitrogens are bonded to the transition metal as a cathode catalyst for a reduction reaction of sulfur generated during operation of the lithium secondary battery having a sulfur-containing material included in a cathode thereof, thereby improving performance and longevity of the battery.
