BATTERY SEPARATOR MATERIAL |
摘要 |
<p>A paper web for use in making a battery separator is formed from a furnish contg. a synthetic pulp; the fibrils of the pulp are filled with an inorganic filler, and the web incoporates a wetting agent. The web is formed on a paper-making machine, and is cheap and homogeneous. The electrical resistance across the separator is low, partic, after extended life in a battery. The pore size is lower, the distribution of pore size is narrower and the porosity is higher than in paper sheets made from wood pulp. The web can be consolidated by heat, and can be embossed to form projections.</p> |
