Embodiment

[0054] In a 50 gallon hot aqueous slurry, a 60 lb batch of tetrabasic lead sulfate (tribasic sulfuric acid) of greater than 90% by weight purity was prepared according to the method described by Biagetti and Weeks, Bell System Technical Journal, September 1970. lead impurities). The dried material was jet milled to a spherical particle size of 1 micron on an average volume basis with a nominal standard deviation of 1 micron. A laser-based particle size analyzer was used to determine the size of all tetrabasic lead sulfate seed particles.

[0055] These tetrabasic lead sulfate seed particles were added to 2400 lbs of conventional lead oxide paste mixture to achieve the desired loading level of 1% by weight (eg, 24 lbs of lead sulfate seed was added to the mixture). Mixing as is typical in the art is then performed by adding water, followed by the addition of sulfuric acid having a specific gravity of 1.325 in quantity to achieve a nominal peak mixing temperature of 60° C. over...

Abstract

A method of making a battery plate includes mixing particles of tetrabasic lead sulfate with leady oxide to form a paste material. The particles have an average spherical particle diameter of less than 2.5 micrometers. The method also includes providing at least a portion of the paste material on a battery grid curing the battery grid and paste material at a temperature of less than approximately 48 degrees Celsius to produce a battery plate having a cured paste thereon.

Description

[0001] Cross references to related patent applications [0002] This application claims priority to co-pending US Provisional Patent Application Serial No. 60 / 512,951, filed October 21,2003. The entire content of the following patent application is hereby incorporated by reference into this application: Pending US Provisional Patent Application No. 60 / 512,951, filed October 21, 2003. technical field [0003] The present invention relates generally to the field of batteries (eg, lead-acid batteries, such as automotive starting, lighting and ignition (SLI) batteries; industrial batteries; commercial batteries; and marine batteries). More specifically, the present invention relates to materials for use in battery active materials and methods of making the materials. Background technique [0004] The positive and negative plates or grids used in lead-acid batteries are fabricated from lead or lead alloys and include multiple wires connected to multiple nodes (for example, a bat...
