Abstract:
1. A lithium ion-sulfur battery comprising: a lithium metal plate as a supply source of lithium ions; first and second sulfur electrodes as positive electrodes; first and second intercalation electrodes as negative electrodes after the lithium ions are intercalated from the lithium metal plate to be charged and discharged together with the first and second sulfur electrodes, wherein each of the first and second intercalation electrodes is interposed between the lithium metal plate and each of the first and second sulfur electrodes, and each of the first and second intercalation electrodes comprises a metal electrode in the form of a mesh to have a structure receiving the intercalated lithium ions; first, second, third and fourth separator membranes; and an electrolyte, wherein the first separator membrane, the first intercalation electrode, the second separator membrane, and the first sulfur electrode are sequentially stacked on a first side of the lithium metal plate; the third separator membrane, the second intercalation electrode, the fourth separator membrane and the second sulfur electrode are sequentially stacked on a second side of the lithium metal plate opposed of the first side; and the electrolyte is impregnated therein, such that the lithium metal plate only supplies the lithium ions into the first and second intercalation electrodes during initial charge and the lithium metal plate is disconnected from electric circuits to the first and second intercalation electrodes, each of the first and second intercalation electrodes is connected to each of the first and second sulfur electrodes and serve as negative electrodes in the lithium ion-sulfur battery.
