Abstract
This invention provides a non-aqueous electrolyte magnesium secondary battery comprising a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte, the non-aqueous electrolyte comprising [N(SO2CF3)2]− as an anion, and Mg2+ and/or an organic onium cation as a cation.
Claims6
A non-aqueous electrolyte magnesium secondary battery comprising a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte,
- wherein the non-aqueous electrolyte consists of Mg[N(SO2CF3)2]2 as an electrolyte salt and an ionic liquid as a solvent,
- wherein the ionic liquid consists of [N(SO2CF3)2]− as an anion and an organic onium cation as a cation,
- wherein the organic onium cation is at least one cation selected from the group consisting of tetramethylammonium (N1111), tetraethylammonium (N2222), tetra n-propylammonium (N3333), tetra n-butylammonium (N4444), tetra n-pentylammonium (N5555), and 5-azoniaspiro[4.4]nonane (AS44).
