Abstract
A flooded lead-acid battery include a pasting substrate embedded into an active material of at least one surface of either the positive plates or the negative plates of each respective plurality, wherein the pasting substrate has an initial thickness. The pasting substrate thickness has a compressed thickness within the container that is at least 10 to 20% less than the initial thickness.
Claims8
A flooded lead-acid battery, comprising:
- a container;
- a plurality of positive plates disposed in the container;
- a plurality of negative plates disposed in the container;
- a pasting substrate embedded into an active material of at least one surface of either the positive plates or the negative plates of each respective plurality, wherein the pasting substrate has a basis weight of 23 g/m2 to 31 g/m2 and the pasting substrate and comprises greater than about 50 wt. % glass fibers based on a total weight of the pasting substrate, wherein the pasting substrate comprises a blend of fibers having an average fiber diameter of 5 μm to 8 μm with fibers having an average fiber diameter of 11 to 14 μm, wherein the pasting substrate thickness has a compressed thickness within the container that is at least 10 to 20% less than the initial thickness;
- and
- an electrolyte disposed in the container to a sufficient level to flood the plurality of positive and negative plates.
