Abstract
(EN)
The present invention relates to a lithium secondary battery system comprising a molybdenum sulfide (MoS2) electrode and, more specifically, to a lithium secondary battery system having electrochemical properties enhanced by the control of charge/discharge voltages and the co-insertion of lithium-electrolyte through solvent electrolyte control. In the secondary battery system according to the present invention, an ether-based solvent able to be co-inserted, together with lithium ions, into the interlayer of MoS2 is employed as an electrolyte solvent and the charge/discharge voltage condition is controlled to 1.0-3.0 V, thereby enhancing electrochemical properties of the battery, such as the battery’s rate, lifespan, and so forth.

La présente invention concerne un système de batterie secondaire au lithium comprenant une électrode à base de sulfure de molybdène (MoS2) et, plus particulièrement, un système de batterie secondaire au lithium ayant des propriétés électrochimiques améliorées par la commande de tensions de charge/décharge et la co-insertion d'électrolyte de lithium par commande d'électrolyte de solvant. Dans le système de batterie secondaire selon la présente invention, un solvant à base d'éther pouvant être co-inséré, conjointement avec des ions lithium, dans la couche intermédiaire de MoS2 est utilisé en tant que solvant d'électrolyte et la condition de tension de charge/décharge est commandée de 1,0 à 3,0 V, ce qui permet d'améliorer les propriétés électrochimiques de la batterie, telles que le régime de la batterie, la durée de vie, etc.
