Abstract
【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
Description
ニッケル水素電池は、使用により容量が徐々に劣化し得る。容量劣化の要因の1つは、負極の水素吸蔵合金から水素が排出されてしまい、負極容量が劣化することにあると考えられる。上述した特許文献1に開示された技術では、ニッケル水素電池に対して過充電を行なって負極に水素を充填することによって、負極容量を回復させている。
Claims (5)
