Abstract
There is provided an electrolyte solution including a solvent formed from a sulfone, and a magnesium salt dissolved in the solvent.
Claims18
An electrolyte solution comprising:
- a solvent formed from a sulfone;
- and
- a magnesium salt dissolved in the solvent,
- wherein a molar ratio of the sulfone based on the magnesium salt in the electrolyte solution is 4 or more to 35 or less.
1 more element
A method for producing an electrolyte solution, the method comprising:
- dissolving a magnesium salt in a low-boiling-point solvent capable of dissolving a magnesium salt;
- dissolving a sulfone in a solution in which the magnesium salt is dissolved in the low-boiling-point solvent;
- and
- removing the low-boiling-point solvent from the solution in which the sulfone is dissolved.
1 more element
An electrolyte solution comprising:
- a solvent formed from a sulfone and a non-polar solvent;
- and
- a magnesium salt dissolved in the solvent,
- wherein a molar ratio of the sulfone based on the magnesium salt in the electrolyte solution is 4 or more to 20 or less.

A method for producing an electrolyte solution, the method comprising:
- dissolving a magnesium salt in a low-boiling-point solvent capable of dissolving a magnesium salt;
- dissolving a sulfone in a solution in which the magnesium salt is dissolved in the low-boiling-point solvent;
- removing the low-boiling-point solvent from the solution in which the sulfone is dissolved;
- and
- mixing a non-polar solvent in the solution from which the low-boiling-point solvent was removed.
2 more elements
An electrochemical device comprising:
- an electrolyte solution,
- wherein the electrolyte solution is
- a solution including a solvent formed from a sulfone and a magnesium salt dissolved in the solvent, wherein a molar ratio of the sulfone based on the magnesium salt in the electrolyte solution is 4 or more to 35 or less, or
- a solution including a solvent formed from a sulfone and a non-polar solvent, and a magnesium salt dissolved in the solvent, wherein a molar ratio of the sulfone based on the magnesium salt in the electrolyte solution is 4 or more to 20 or less.
