FLUORINE-CONTAINING MAGNESIUM COMPOUND

Document Type and Number:

Japanese Patent JP2014214040

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a fluorine-containing magnesium compound which can reversibly insert and extract magnesium ions, secure a high voltage and energy density during oxidation-reduction reaction (charge-discharge reaction) and has safety and excellent practicality, and to provide a positive electrode active material, a positive electrode and a magnesium secondary battery.SOLUTION: There are provided: a fluorine-containing magnesium compound having a composition represented by the formula MgMAOF(wherein, M represents a transition metal atom, a tin atom, an antimony atom or an indium atom; A represents a phosphorus atom, a silicon atom or a sulfur atom; m is a number larger than 0 and 2 or less; p is 3 or 4; q is a number of 0.5 to 1.5); a positive electrode active material; a positive electrode containing the active material; and a magnesium secondary battery provided with the positive electrode.
