ABSTRACT:
A porous compressible plastic material is inserted into the head space above the cells in a storage battery to attenuate the explosion of combustible gases accumulating therein. The attenuation material is distributed to create a unique bimodal por distribution, including a major proportion of small pores effective in attenuation and a minor proportion of large pores effective in gas and electrolyte management. Both open cell and fibrous materials may be utilized.
