Abstract:
(EN) Disclosed is a method for improving the life of a lithium-sulfur secondary battery capable of improving the life properties of the secondary battery by inducing uniform reaction of the lithium-sulfur secondary battery. The method for improving the life of the lithium-sulfur secondary battery includes a self-activation step of charging to reach a zone in which a long-chain lithium polysulfide is formed in the process of charging the lithium-sulfur secondary battery, and then allowing ten minutes to four hours of rest time.
(FR) L'invention concerne un procédé destiné à améliorer la durée de vie d'une batterie secondaire au lithium-soufre, permettant d'améliorer les propriétés de vie de la batterie secondaire par induction d'une réaction uniforme de ladite batterie. Le procédé selon l'invention comprend une étape d'auto-activation de charge pour atteindre une zone dans laquelle un polysulfure de lithium à longue chaîne est formé dans le processus de charge de la batterie secondaire au lithium-soufre, puis une étape de repos durant de dix minutes à quatre heures.
(KO) 리튬-황 이차전지의 균일한 반응을 유도하여 이차전지의 수명특성을 개선시킬 수 있는, 리튬-황 이차전지의 수명 개선방법이 개시된다. 상기 리튬-황 이차전지의 수명 개선방법은, 리튬-황 이차전지의 충전 과정에 있어서, 장 사슬 리튬 폴리설파이드(long chain lithium polysulfide)가 형성되는 영역에 도달하도록 충전한 후, 10 분 내지 4 시간의 휴지기(rest time)를 부여하는 자기 활성화 단계(Self-activation step)를 포함한다.
