摘要:
This invention provides an inorganic fiber paper that consists essentially of inorganic materials and has a basis weight of less than 100 g/m2 and has been mainly produced by a wet sheet making method. The inorganic fiber paper comprises inorganic fibers and an inorganic binder as materials, wherein the inorganic fibers have been bound to each other with the inorganic binder. In the inorganic fiber paper, the content of impurities during wet sheet making is low, the water resistance and flexibility are good, and satisfactory strength and high porosity can be realized. The inorganic fiber paper is produced from a material comprising 60 to 97% by mass of inorganic fibers having an average fiber diameter of not more than 5 μm and 3 to 40% by mass of an inorganic binder composed mainly of a silica-based flaky inorganic material that has a hydroxyl group content per specific surface area of not less than 20 μmol/m2 as measured by a BET method, an average particle diameter of not more than 2 μm as measured by a laser scattering method and an aspect ratio of not less than 10.

摘要:
A separator for a lead-acid battery, a pasting paper for a lead-acid battery, a plate for a lead-acid battery, and a lead-acid battery using the same are disclosed. The separator comprises a microporous sheet containing a heavy metal adsorbent comprising a rare earth compound having high heavy metal adsorbability in a neutral region and low heavy metal adsorbability in an acidic region, wherein the heavy metal adsorbent is unevenly distributed in a thickness direction of the sheet, thereby forming the heavy metal adsorbent-containing layer extending in a horizontal direction of the sheet and a layer which does not substantially contain the heavy metal adsorbent.
摘要:
The separator for storage battery of the present invention is a separator for storage battery mainly composed of microfibrous glass and an expanded microcapsule which has been kept in shape with its shell rendered water-permeable by expansion is incorporated in the aforesaid microfibrous glass so that an electrolyte can be retained in the gap between the glass fibers and in the expanded microcapsule to provide a high electrolyte retention and allow the aforesaid expanded microcapsule to act as a cushioning material, whereby the separator is provided with an enhanced restoring force under pressure and is thus kept the adhesion to the electrode over an extended period of time, making it possible to attain the enhancement of the storage battery capacity and the prolongation of its life and apply only a low pressure to incorporate the electrode group in the battery case during assembly of storage battery.
