Title:
MAGNESIUM AIR BATTERY HAVING PLURALITY OF CELLS
Document Type and Number:
WIPO Patent Application WO/2016/088610
Kind Code:
A1
Abstract:
[Problem] To improve the current continuation time and the discharge capacity of a magnesium air battery having a plurality of cells. [Solution] A magnesium air battery 10 comprising a case 11 having: four cells 20 layered therein and enclosed in a state in which a conductive metal plate 28 is laminated on one end; and the lower surface thereof being sealed by a cap 15 having a through-hole 16 formed therein. Each cell 20 comprises: a stainless steel positive electrode 21; a positive electrode active substance 22 including an activated carbon; an electrolyte layer 23 comprising a separator plate holding an electrolyte; and a negative electrode 24 comprising a magnesium alloy AZ31. Osmosis of the electrolyte between cells is suppressed as a result of providing a conductive adhesive layer 30 between the cells. As a result, occurrence of counter electromotive voltage between cells and generation of magnesium hydroxide can be suppressed and the continuous power generation period and discharge capacity can be improved.
