Novel Battery Plate Assembly and Method of Assembly

The World Intellectual Property Organization (WIPO) published a patent application WO/2011/130514 on October 20, describing a novel battery plate assembly and method of assembly. The invention, submitted by Johnson Controls Technology Company, proposes an improved design for lead-acid battery plates. The abstract outlines a unique grid body structure with opposed frame elements, conductive grid elements, and an active material coating. The design incorporates a highly absorbent separator wrapped around the plate to enhance electrolyte retention.

Key Takeaways:

• The invention involves a battery plate assembly for a lead-acid battery, comprising plates of opposite polarity with an electrically conductive grid body, opposed frame elements, and conductive grid elements.
• The grid body has opposed frame elements, a lug, and an enlarged conductive section, as well as a plurality of interconnecting grid elements defining a grid pattern with open areas.
• A highly absorbent separator is wrapped around at least a portion of the plate of a first polarity, extending to the opposing plate face.
• An electrolyte is provided, with substantially all of the electrolyte absorbed by the separator or active material.
• The patent was filed on April 14, 2011, under Application No. PCT/US2011/032498.
• Johnson Controls Technology Company is the applicant for the patent, with inventors Robert Mack, J. and Jeffrey L. Troxel listed.
• The novel design aims to enhance the performance and efficiency of lead-acid battery plates.
