発明の名称 (英語) ELECTROLYTE SOLUTION, SECONDARY BATTERY AND METHOD FOR PRODUCING ELECTROLYTE SOLUTION NEW
発明の概要(英語) Provided is an electrolyte solution which is capable of maintaining a high magnesium ion concentration. An electrolyte solution according to one embodiment of the present invention is obtained by mixing a solvent, magnesium metal and an elemental halogen.
従来技術、競合技術の概要(英語) BACKGROUND ART
Current as a secondary battery has been widely used for the lithium ion secondary battery, magnesium secondary battery using magnesium as a negative electrode is, 'next-generation secondary battery' have garnered attention as.The magnesium secondary battery, the amount of electricity per unit volume often available, is inexpensive and is rich in the metal resources, safety is high in the air in view of, the lithium ion secondary battery is advantageous.
The magnesium secondary battery, when discharge of the magnesium metal is dissolved as magnesium ions, magnesium ions at the time of the charging as a magnesium metal to be deposited.Therefore, the electrolyte for the magnesium secondary battery, a sufficient amount of magnesium ions and held, and the negative electrode (magnesium metal) between the deposition and dissolution reaction efficiently generated on the obtained characteristics.
Such electrolytic solution as an example, Patent Document 1 is, the magnesium salt dissolved in a solvent consisting of a sulfonic acid electrolyte was disclosed.This technique further, as a method of manufacturing the electrolyte of the magnesium salt is dissolved, (1) a low boiling point solvent (for example, alcohol) the steps of dissolving a magnesium salt, (2) (1) a solution obtained by dissolving the sulfonic acid in the step from the solution obtained, (3) (2) a step of removing the low boiling point solvent, and has disclosed a method for manufacturing.
In addition, Patent Document 2 is, magnesium ions, the ion conductive medium comprising a halogen and a non-aqueous solvent has been disclosed.According to this document, the ion conductivity in the medium, the non-aqueous solvent and halogen to form the molecular complex.
