20130202954 | MAGNESIUM BATTERY - The magnesium battery according to the present invention has a negative electrode which is composed of magnesium and a liquid-retaining section in which an aqueous electrolytic solution that can cause the elution of magnesium ions from the negative electrode can be retained. The liquid-retaining section can retain an aqueous solution of a citric acid salt as an aqueous electrolytic solution and can generate an electromotive force sustainably between the negative electrode and a positive electrode. Thus, citric acid salt ions and magnesium ions eluted from the negative electrode form a complex, thereby increasing the solubility of the magnesium ions. As a result, the precipitation of magnesium oxide in the negative electrode can be prevented and magnesium can be electrolyzed sustainably, whereby the negative electrode capacity in the magnesium battery can be sustainably high. | 08-08-2013 |
