Provided is a magnesium secondary battery including a positive electrode member 23 including at least a positive electrode active material layer 23B, a separator 24 disposed facing the positive electrode member 23, a negative electrode member 25 containing magnesium or a magnesium compound disposed facing the separator 24, and an electrolytic solution containing a magnesium salt. The positive electrode active material layer 23B includes magnesium sulfide having a zinc blende type crystal structure.

The present disclosure relates to an apparatus and a method for preparing a disinfectant or a cleaning agent according to an additive. Specifically, the present disclosure relates to an electrolysis apparatus comprising: an additive container to which an additive to be used for electrolysis is added; and a diaphragm-free electrolysis cell in which the electrolysis occurs, wherein, with respect to the electrolysis, water containing chloride ions (Cl.sup.), sodium chloride (NaCl) and a hydrochloric acid (HCl) aqueous solution are electrolyzed in the diaphragm-free electrolysis cell.

Provided is a method of preparing an activated mineral solution, which includes steps of pulverizing granite and/or vermiculite into a powder by grinding, subjecting the powder to an electrolysis treatment, dissolving the powder in an aqueous ammonia solution and an acidic solution to prepare a mixed solution, emitting ultrasonic waves on the mixed solution, introducing microorganisms onto the mixed solution, and neutralizing the mixed solution, in which the mineral is selected from the group consisting of Fe, Mg, Al, Ti, K, Ca, Mn, Nb, P, Na, Zn, V, Cr, Ni, Si, B, Cu, Li, Ga, Co, Sr, In, Rb, Sb, Ta, Y, and combinations thereof.

There are provided methods and systems for an electrochemical cell including an anode and a cathode where the anode is contacted with a metal ion that converts the metal ion from a lower oxidation state to a higher oxidation state. The metal ion in the higher oxidation state is reacted with hydrogen gas, an unsaturated hydrocarbon, and/or a saturated hydrocarbon to form products.
