Embodiment 1

[0056] In Example 1, it was made according to image 3 The physical type of spacer shown. Photographs were taken of the clapboard, shown in figure 1 and figure 2 .

Embodiment 2

[0058] In Example 2, several cells were constructed and tested to determine how well the improved separator according to the present invention would function. The batteries used were tubular flooded inverter batteries, commercially available from Aegan Batteries, Bangalore, India. The battery tested was 12V100Ah at 20 hours. The number of plates per unit is 9 (4 positive, 5 negative). The antimony content in the grid is 2.5%. The average dry plate weight for the positive plates was 474.5 grams, and the average dry plate weight for the negative plates was 336 grams. The weight of the positive plate group is 1898+ / -2 grams / unit; the weight of the negative plate group is 1680+ / -1 grams / unit.

[0059] For the experimental cells, the separator used was a backplate thickness of about 400 microns, an overall thickness of about 1.6 mm and according to image 3 Coated polyethylene separator with zigzag profile. This experimental separator was coated with surfactant coatings at two...

Abstract

New, improved or optimized battery separators, components, batteries, industrial batteries, inverter batteries, batteries for heavy or light industrial applications, forklift batteries, float charged batteries, inverters, accumulators, systems, methods, profiles, additives, compositions, composites, mixes, coatings, and / or related methods of water retention, water loss prevention, improved charge acceptance, production, use, and / or combinations thereof are provided or disclosed. More particularly, the present invention is directed to one or more improved battery separators having various improvements that may result in decreased water loss for a battery in which such a separator is incorporated, enhanced charge acceptance, or combinations thereof. Additionally, the present invention relates to one or more improved battery separators having various improvements with regard to shape, and / or physical profile, and / or chemical(s), additives, mixes, coatings, and / or the like used to make such battery separators (such as oil(s), and / or chemical additive(s) or agents used to coat, finish or improve such battery separators (such as surfactant(s))). The improved battery separators of the instant invention are particularly useful in or with industrial batteries, such as inverter batteries, batteries for heavy or light duty industrial applications, and so forth.
