Abstract:
(EN) Disclosed is a method for improving the life properties and the charging speed of a lithium-sulfur secondary battery, capable of simultaneously improving the life properties and the charging speed of the secondary battery by inducing uniform reaction of the lithium-sulfur secondary battery. The method for improving the life properties and the charging speed of the lithium-sulfur secondary battery comprises a step of applying a graduated charging speed for each section when charging the lithium-sulfur secondary battery.
(FR) Cette invention concerne un procédé conçu pour améliorer les propriétés de durée de vie et la vitesse de charge d'une batterie rechargeable au lithium-soufre, apte à améliorer simultanément les propriétés de durée de vie et la vitesse de charge de la batterie rechargeable en induisant une réaction uniforme de la batterie rechargeable au lithium-soufre. Le procédé conçu pour améliorer les propriétés de vie et la vitesse de charge de la batterie rechargeable au lithium-soufre comprend une étape d'application d'une vitesse de charge progressive pour chaque section lors de la charge de la batterie rechargeable au lithium-soufre.
(KO) 리튬-황 이차전지의 균일한 반응을 유도하여 이차전지의 수명특성과 충전속도를 동시에 개선시킬 수 있는, 리튬-황 이차전지의 수명특성 및 충전속도 개선방법이 개시된다. 상기 리튬-황 이차전지의 수명특성 및 충전속도 개선방법은, 리튬-황 이차전지의 충전 과정에 있어서, 충전속도를 구간별로 차등 적용하는 단계;를 포함한다.
