To increase the positive electrode capacity of a nickel hydrogen battery.SOLUTION: A manufacturing method of a nickel hydrogen battery includes a first step of preparing a first nickel hydrogen battery including nickel hydroxide Ni (OH)on a positive electrode, and a second step of manufacturing a second nickel hydrogen battery by performing 600% overcharge on the prepared first nickel hydrogen battery. The 600% overcharge is a process of supplying 600% of the rated capacity of the first nickel hydrogen battery to the first nickel hydrogen battery.SELECTED DRAWING: Figure 4 【課題】ニッケル水素電池の正極容量を増加させる。【解決手段】ニッケル水素電池の製造方法は、正極に水酸化ニッケルＮｉ（ＯＨ）２を含む第１ニッケル水素電池を準備する第１工程と、準備された第１ニッケル水素電池に対して６００％過充電を行なうことによって第２ニッケル水素電池を製造する第２工程とを含む。６００％過充電は、第１ニッケル水素電池の定格容量の６００パーセントの電力量を第１ニッケル水素電池に供給する処理である。【選択図】図４
