Abstract
Porous compressible plastic material, effective in attenuating the explosion of combustible gases which accumulate in the head space of a storage battery, is prepared for installation by compressing the material and maintaining the compression with a releasable binding means. The compressed attenuation material is inserted into the head space of the battery and, upon release of the binding means, the material reexpands to fill the head space. Various embodiments of the general method are disclosed and each may be used with a variety of open cell and fibrous plastic materials. The releasable binder may be either a physical enclosure or a chemical adhesive, each of which is preferably releasable by dissolution in the battery electrolyte.
