| titleOfInvention | Manufacturing method of nickel-metal hydride secondary battery and nickel-hydrogen secondary battery |
| abstract | PROBLEM TO BE SOLVED: To reduce the content of cobalt in a hydrogen storage alloy while maintaining good battery characteristics of a nickel-metal hydride secondary battery. SOLUTION: In a positive electrode plate 15 having a positive electrode mixture, a negative electrode plate 16 having a negative electrode mixture containing a hydrogen storage alloy, and a nickel hydrogen secondary battery including an electrolytic solution, the hydrogen storage alloy contains cobalt and the electrolytic solution is. When the weight of the electrolytic solution contains 1.0% by weight or less of the tungsten element, and the mass ratio of cobalt is more than 0 mol% and 0.05 mol or less, and the distance between the electrodes is 75 μm or less, the tungsten element When the weight ratio is 0.1% by weight or more and the distance between the poles is more than 75 μm and 100 μm or less, the weight ratio of the tungsten element is 0.3% by weight or more and the distance between the poles is more than 100 μm and 150 μm or less. When the weight ratio of the element is 0.5% by weight or more and the distance between the poles is more than 150 μm and 200 μm or less, the weight ratio of the tungsten element is 0.6% by weight or more.
