PURPOSE:To provide a nickel - zinc battery having a long service life by setting the thickness total of a nickel electrode, a zinc electrode and a separator in a specific % of the electrode plate laminating directional internal dimension of a battery jar. CONSTITUTION:A positive electrode plate and a negative electrode plate are wrapped in a single polyamide nonwoven fabric, and the positive electrode plate is also wrapped doubly in polypropylene microporous film. The two positive electrode paltes and the three negative electrode plates are combined with each other, and a plate group can be formed. This plate group is inserted into an acrylic battery jar, and potassium hydroxide aqueous solution formed by saturating oxidized zinc is injected, and a nickel - zinc battery can be obtained. A ratio of a plate group thickness of the battery to a battery jar internal dimension is set in 85-95%. |
