Abstract
Official abstract text for this publication.
An electrochemical device including a negative electrode made of a magnesium-based material includes an electrolyte solution consisting of a solvent composed of linear ether, and magnesium salt dissolved in the solvent, in which the magnesium salt is dissolved in 3 moles or more per liter of the solvent.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrochemical device comprising a negative electrode including a magnesium-based material, and a positive electrode including S 8 or polymeric sulfur, wherein the electrochemical device includes an electrolyte solution consisting of a solvent composed of linear ether, and magnesium salt dissolved in the solvent, wherein a total concentration of the magnesium salt in the electrolyte solution is in a high concentration state such that the magnesium salt is dissolved in 3 moles or more per liter of the solvent, thereby the solvent in the electrolyte solution is in a state of being substantially coordinated to the magnesium salt and not substantially coordinated to the S 8 or polymeric sulfur, and wherein solubility of S 8 or polymeric sulfur is 0.5 milligram or less per milliliter of the electrolyte solution. 2. The electrochemical device according to claim 1 , wherein the magnesium salt is MgCl 2 and Mg(TFSI) 2 . 3. The electrochemical device according to claim 1 , wherein the solvent is dimethoxyethane.
