PURPOSE:To prevent deterioration of a positive plate and increase life of a sealed lead-acid battery by accommodating a carbon dioxide absorbing material in the space inside a battery. CONSTITUTION:A carbon dioxide absorbing material 5 is accommodated in the space inside a battery. Basic materials or those solutions such as oxides or hydroxides of calcium, barium, potassium, sodium, or porous materials such as zeolite, carbon are used as the carbon oxide absorbing material. The carbon dioxide absorbing material is wrapt with a sheet or a mat, or impregnated in a porous body, or accommodated in a container having an opening at its upper part, then it is set in the space inside a battery. Therefore, since carbon dioxide is practically removed, formation of barrier is prevented and life is increased. |
