Batterie mit nichtwässrigem Elektrolyten

摘要

A non-aqueous electrolyte battery capable of quickly diffusing magnesium ions and improving cycle operation resistance, incorporating a positive electrode containing LixMO2 (where M is an element containing at least Ni or Co) as a positive-electrode active material thereof; a negative electrode disposed opposite to the positive electrode and containing a negative-electrode active material which permits doping/dedoping magnesium ions: and a non-aqueous electrolyte disposed between the positive electrode and the negative electrode and containing non-aqueous solvent and an electrolyte constituted by magnesium salt, wherein the value of x of LixMO2 satisfies a range 0.1 ≤ x ≤ 0.5.
